This study was carried out in the Central Region of Uganda, where most of the final tomato transactions are carried out. They observed that several farmers poorly store their agrochemicals, whereby some keep them around food and in places easily accessible to children, which endangers their lives. Markets and Farms Sampled with Their Main Regional Source of Supplies. ETU is responsible for the toxicity effects during chronic exposure and also known to be carcinogenic and teratogenic in rats.4,5 In addition, laboratory animals that ingested dithiocarbamates were shown to develop neuropathology, thyroid toxicity, and developmental toxicity to the central nervous system. tomatoes in the Kamuli District (Akemn, 2000). Dealing with pesticides in tomato production. The study discovered that contamination is highest at the end of June and beginning of July. Phytophthora infestans isolates from tomatoes were obtained from the zones and only the A1 mating type was recovered. Conclusions. Contact dermatitis has also been reported in workers exposed to mancozeb; the metabolite ETU is suspected to be goitrogenic and teratogenic in humans. All Rights Reserved. Dr. Ssekimpi says; “Some farmers told us they spray their crops even on the day they are going to sell them so as to make them attractive. Amateur rodade. We know that some of the Chemicals are fake. “When it comes to water sources, the number of contaminants increases from seven in April to more than 23 different contaminants at the end of June, due to increased use of pesticides and herbicides,” Dr. Ssekimpi observes. According to scientists from Centre for Agriculture and Bioscience International-CABI, a human health risk assessment done in Ghana showed high cancer risk for adults and children due to the presence of chlorpyrifos, an organophosphate pesticide. Objectives. Pesticide free tomatoes for blanc control could not be obtained. It was observed that none of the farmers used personal protection equipment during the application of macozeb nor during harvesting. Seedlings are usually ready for transplanting 3-4 weeks after sowing, and they must be transplanted on moist soil. Unfortunately, the current Ministry of Health Data Capture system does not clearly capture acute pesticide poisoning as a major community health concern.”. From this, a selected ion monitoring (SIM) method was developed with the target ion for carbon disulfide being mz 76 along with 44 and 78 as reference ions. While Kalumaba mentions many other tomato varieties that can thrive in Ugandan soils, he believes the choice is always in the hands of the farmer. Mancozeb belongs to a group of pesticides known as dithiocarbamates (DTC) that are a non-systemic group of pesticides extensively used in Uganda to protect crops from fungal diseases. doi: https://doi.org/10.5696/i2156-9614-5-8.1. Like onions, tomatoes are some of the high value crops all over the world and one of the best-selling in Uganda. Up to eight harmful pesticide contaminants have been found in tomatoes sold in major markets in Kampala and other parts of Uganda. The column used was an Agilent (Santa Clara, USA) J&W GC column (GS-GASPRO, length 30 m, diameter 0.32 mm with no film thickness). Initially, a standard at a high concentration was run in full scan acquisition mode, the MS was in positive electron impact mode at 70 eV and mass detection range was a mass-to-charge ratio (mz) of 40–550. Tomatoes are one of the most cultivated crops, Tomato crops can be easily grown under proper conditions and regular maintenance.Tomato crops can host of production problems and pathogens when conditions and maintenance are not ideal. The authors declare no competing financial interests. There are more than 300 registered pesticides in Uganda, according to USAID. The system was calibrated daily using perfluorotributylamine.

The problem with tomatoes is that the leaves hang downward, making it difficult to reach the underside. Higher pressures and higher volumes will only partly solve the problem. Pesticide misuse by farmers poses health risks to consumers. Incorporate in manure or potting agents like biocha to enhance the nutrients. Procedural recoveries were determined concurrently with each batch of analytical extracts by analysing the carbon disulphide evolved after digestion of the spiked tomato samples with mancozeb standard. The scientists, who discovered that there are contaminated tomatoes in all the sample districts, observed that unless regulated fast enough, the problem of misuse of pesticides is a ticking time bomb for Uganda that is likely to result in sporadic cancer infections across the country. In Uganda, the work on ARM started with NEPAD and FAO in 2013, and PARM had its risk assessment workshop in June 2015, always in partnership with the Ministry of Agriculture, Animal Industry and Fisheries (MAAIF). The main tomato variety grown in this region is Lycopersicon esculentum. The pests that attack tomatoes include Aphids, Boll worms and Termites. The study also found that farmers applied 3–6 times the dosage of mancozeb recommended by manufacturers. The findings are summarized in Tables 2 and 3. The samples were frozen and cut to minimize degradation of mancozeb when in contact with acidic tomato juices. Pesticide residue research supports a number of activities including crop protection, environmental monitoring, consumer protection, and legislative enforcement. While much about modern farming techniques centers around the use of synthetic pesticides (a catch-all term that includes herbicides, insecticides, and fungicides) on large acreage, organic producers of all sizes also use a variety of chemicals to control … A new study has revealed that most of the tomatoes being consumed in Uganda are poisonous because they are contaminated with deadly pesticides. This arose from past experience of recommended dosages resulting in very dilute solutions that did not serve the intended purpose. There are also allegations of substance abuse and misuse of the post-harvest application to prolong the shelf life of fruit.2. The organic phase (isooctane) was removed and placed in a vial prior to the quantitation of carbon disulphide by GC-MS. The observed practices at farms are likely to put farmers and final consumers at a risk of exposure to dithiocarbamates. This study was done in 5 selected districts of Central Uganda with a focus on markets and farms to investigate the current mancozeb concentrations on tomatoes and identify key areas of improvement … Diseases and pests that attack tomatoes The tomatoes are attached by the following diseases: Bacteria wilt, Blights, Blossom and; Fungal diseases. Using the GC-MS technique, the mancozeb detected as CS2 was identified at a retention time of 6.7 minutes and confirmed with the corresponding selected ions in the mass spectrum as shown in Figure 1. The bottles were then placed in a freezer for 30 minutes to allow the generated carbon disulphide gas to condense. San-marzano. Picture 1. The carrier gas was helium (purity 99.999%) at flow rate of 2.0 ml/min. Although tomatoes serve as a source of livelihood for many rural farmers in Uganda, pests hinder their production. A 5-point calibration was done, ranging from 0.125–5 μg/ml. Copyright ©2019, The Publicist East Africa. Wedge-shaped portions that included outer surfaces from each tomato were prepared.17 Representative portions were taken by mixing opposite quarters and a 50±0.1 g portion required for analysis was weighed into 250 ml gas-tight reaction Duran bottles.9 Iso-octane (20 ml) was added, followed by stannous (II) chloride (reducing solution) in diluted hydrochloric acid (100 ml), and sealed immediately with a cap. This could be attributed to the low level of awareness about the toxicity of mancozeb and the sheer lack of personal protective equipment. Basically, treating a wide range of symptoms presented by many diseases. Extracts of Lippia javanica leaf powder and Solanum delagoense ripe fruit pulp were evaluated for pesticidal effects under on-station conditions against rape aphids and tomato red spider mites as alternatives to conventional pesticides and in They are known to attack tomato plant at the early stage of planting and on the stem. by Atuhaire et al. 12 It is based on the method as originally published, with some modifications which have been validated.13–16 In this method, mancozeb is converted to carbon disulphide (CS2) which is measured by gas chromatography—mass spectrometer (GC-MS) in the electron impact—selected ion monitoring mode. A new study has revealed that most of the tomatoes being consumed in Uganda are poisonous because they are contaminated with deadly pesticides. Mancozeb belongs to a group of pesticides known as dithiocarbamates (DTC) that are a non-systemic group of pesticides extensively used in Uganda to protect crops from fungal diseases. The toxicity of mancozeb, maneb, metiram under the chemical group ethylene bisdithiocarbamate in food is related to the metabolite or its degradation product ethylene thiourea (ETU). According to the scientists, the contamination in water sources is as a result of poor disposal of pesticide containers, spraying near water sources or washing sprayers in community water sources, although at times the contaminants are washed into these sources by rainwater. Dr. Ssekimpi notes that the study also discovered a very worrying trend of Community water source pollution with harmful pesticide residues, which is brought about by poor handling of pesticides by farmers. These are: Kampala, Mukono, Wakiso, Mityana and Mpigi. Roma. Emmanuel Kaye, Antony Nyombi, Innocent Louis Mutambuze, Ruth Muwesa; Mancozeb Residue on Tomatoes in Central Uganda. The sampling approach included purchasing tomatoes from various randomly selected vendors in the markets and growers at the farms.7,8 At least 3 replicate samples were selected from each location with each sample consisting of at least 10 tomatoes, as suggested in the Codex guidelines.9–11 These were packaged in new polythene bags that were marked with unique identifier codes and sealed tight to avoid movement that could cause loss of mancozeb surface residues. The hydrochloric acid and stannous chloride were obtained from Sigma-Aldrich (St. Louis, USA); iso-octane was purchased from Fisher Scientific (Waltham, USA); and lactose was obtained from LabChemie (Mumbai, India). Most farmers spray the pesticide directly on ripening tomatoes and don’t observe pre-harvest intervals. A total of 57 samples obtained from 4 farms and 13 markets were analyzed. Kampala, Uganda | THE INDEPENDENT | Up to eight harmful pesticide contaminants have been found in tomatoes sold in major markets in Kampala and other parts of Uganda. It was observed that farm samples had mean concentrations of 1.03±0.28 mg/kg, while market samples had 0.77±0.49 mg/kg. Sample of the GC-MS chromatogram showing identification and confirmation of CS2. Furthermore, there is no routine pesticide residue food safety monitoring or surveillance plans. Collected samples. Enjoy unlimited access to unrivalled of the biggest topics in marketing, PR & Brand communications alongside practical advice from Brand and Reputation experts across Africa. This could be attributed to vendors who confessed that they preferred leaving visible traces of mancozeb, which was perceived to prolong the shelf life of tomatoes.2. Sample volumes of 1.0 μL were injected in a spitless mode with a solvent cut of 3 minutes. This study had some limitations which include: lack of data on the degradation rates of mancozeb in the Ugandan climate in an open environment versus in a green house, and degradation during transportation and storage of tomatoes. The common dithiocarbamate applied was mancozeb (concentration: 80% wettable powder) and its preharvest application interval was 1–2 days, as opposed to the manufacturers' recommendations of 3–7 days.18,19 The reason given for this short pre-harvest interval was to prolong the shelf-life of tomatoes; also, vendors required visible signs of mancozeb. Marglobe. It was also observed that none of the farmers followed package label instructions for dilution of the powder. All the samples analyzed had detectable concentrations of mancozeb residue. gardening with Doreen Badze. The pesticides approved in organic farming are largely natural ones, though a limited amount of synthetic substances are permitted . Farm visits and interviews revealed that 3 out of the 4 farmers had received some training on pesticide use from the National Agricultural Advisory Services, a body responsible for enhancing agricultural production in Uganda. Farmers respond by using synthetic pesticides which pose environmental challenges. Major Insect Pests of Tomato. In Uganda, intensified production of marketed vegetable crops has led to changing agricultural practices, including crop and input-intensification, a changing set of pests, and increased use and reliance on synthetic pesticides to manage these pests. The observed practices at farms were likely to put the farmers and final consumers at a risk of exposure to dithiocarbamates. All extracts were analyzed using GC-MS (Shimadzu QP2010, Kyoto, Japan). Satisfactory recoveries of between 70 and 110% were obtained and therefore no corrections to the concentrations were made. Besides the contamination of tomatoes and water sources, the researchers also carried out a study to establish pesticide poisoning levels from homes and related registration in health centers where victims go for medical attention. Because tomato fruits are succulent and juicy, it is an easy target for many insects in the field. Methods. Purchased tomatoes. Talking about the same matter, Aggrey Atuhaire, the Coordinator of Pesticide Use, Health and Environment Project at UNACOH, says they collected samples from 86 water sources in the above districts and during their study they established that up to 94% of them were contaminated with at least one detectable concentration of a pesticide residue at the beginning of April and end of June. Gratitude also goes to the Directorate of Government Analytical Laboratory staff for their technical input. Information obtained from mancozeb packets found at farms indicated that the recommended dosages ranged from 40–50 g mancozeb per 20 liters of water. Objectives. Therefore, parametric tests were performed to compare results. When necessary, use only pesticides locally registered for tomatoes or vegetables. Subject: Mancozeb Residue on Tomatoes in Central Uganda, (Optional message may have a maximum of 1000 characters.). From the 13 markets sampled, it was observed that some vendors cleaned their tomatoes, while others did not. Mwanje says; “We have available data on agrochemical use in Uganda. However, the actual dosages applied ranged from 125–300 g mancozeb per 20 liters of water, showing that farmers applied 3 to 6 times more mancozeb than recommended by the manufacturers.

According to Dr. Ssekimpi, results from the scientific analyses indicate that the number of tomatoes contaminated with harmful pesticide residues gets worse at the end of June as the first cropping season March– June nears its end. Pesticide misuse by farmers poses health risks to consumers. Mancozeb belongs to a group of pesticides known as dithiocarbamates (DTC) that are a non-systemic group of pesticides extensively used in Uganda... DOAJ is a community-curated online directory that indexes and provides access to high quality, open access, peer-reviewed journals. It was observed that all the samples analyzed had detectable levels of mancozeb. Several pests were identified as problems for tomato growers; however, none were so … This portal is an active B2B website for all Biocide Suppliers and their products like Biocides. The companies are divided into suppliers for Fungicides, Herbicides, Insecticides, Nematicides, Rodenticides and more. Some of the insect pests that attack tomato include; Aphids:Aphids are known for their ability to increase significantly. Heinz. The data was found to be normally distributed using the Kolmogorov-Smirnov test with a P-value of 0.703 at a 95% confidence level. Mancozeb belongs to a group of pesticides known as dithiocarbamates (DTC) that are a non-systemic group of pesticides extensively used in Uganda to protect crops from fungal diseases. This study assessed the level of dithiocarbamate residues in tomatoes acquired from 20 farmers and 25 … These values were obtained from prior runs during instrument optimisation. Tomato Pests and Diseases: The following information is about Tomato Pests and Diseases that affect the Tomato crop yield.. Therefore, in order to reduce pesticide use in Uganda, the IPM IL needed to work with tomato growers. Taking tomatoes to Juba nearly doubled the price for a box of tomatoes from Shs40,000 to Shs80,000. The interquartile distribution of the DTC concentrations within the samples is shown in Figure 2. Mancozeb belongs to a group of pesticides known as dithiocarbamates (DTC) that are a non-systemic group of pesticides extensively used in Uganda to protect crops from fungal diseases. The other reason was that tomatoes have a short growing period of about three months. The tomatoes received at the laboratories on the 27th of June and further processed the same day. Occupational Health Specialist Victoria Nabankema, who was part of the study, says; “We saw that children are accidentally poisoned while some adults unintentionally use the chemicals for committing suicide. A survey on the tomato late blight situation and current practices for disease management was carried out in Uganda using an informal structured questionnaire approach. The method's LOQ was set at 0.05 mg/kg which equates to the calibration standard of 0.125 μg/ml.12. Results. Furthermore, farms had higher concentrations of mancozeb compared to markets: 1.03±0.28 mg/kg and 0.77±0.49 mg/kg, respectively, although the difference was not statistically significant. They also determined that tomatoes were the number one high-value cash crop in Uganda grown for both local and regional consumption. All vendors and farmers that were approached were willing to take part in this study. Copyright © 2019 The Publicist East Africa , All rights Reserved. Despite some others being genuine, we would like to use extension workers to sensitize people about the dangers of misusing pesticides, insecticides, rodenticides, and other agrochemicals.”.

The analyzed pesticides are documented on DRF-133 version 12 valid from 06-05-2016. It should be noted that over the years, the volume of pesticides imported into Uganda has sharply risen as Climate Change pounds the country, with the emergence of pests like the Fall Army Worms and others exacerbating the problem. The sampling was focused on the markets to look at what final consumers take to their homes, and farms to look at the practice and what goes to the markets. Individual research has reported levels of Dithane M-45, a mancozeb contact fungicide, applied to tomatoes to be 3 to 7 times above the recommended dose.1 It was also noted that the majority of retailers were interested in visible signs of fungicide on tomatoes before purchasing. The study revealed that Mancozeb is extensively used on tomatoes in farms in the central region of Uganda. Atuhaire says that “The greatest concern to experts is that some of the farmers spray without wearing protective gear even in the presence of children, which exposes both the young and adults to deadly health risks.”, Also read: Agripreneurship is the Future of Africa’s Survival, He adds that “Worse still is that the contaminations in tomatoes are scary when compared to recommended international standards for human consumption and the environment, hence the lives of many Ugandans are at risk.”. In this section you can find 50 Pesticide Suppliers in Uganda registered on our portal. Ion source was set at 200°C and interface temperature was 260°C. On the other hand, the highest mean concentrations of mancozeb were observed at Kireka and Nateete markets with 1.52±0.51 mg/kg and 1.64±0.66 mg/kg respectively. Pesticide risks from fruit and vegetable pest management by small farmers in sub-Saharan Africa. All reagents used were analytical grade. The samples were shaken and left for 5 minutes. This study was done in 5 selected districts of Central Uganda with a focus on markets and farms to investigate the current mancozeb concentrations on tomatoes and identify key areas of improvement … Recommendations are provided that the team hopes will lead to a more accelerated and responsive regulatory process. Furthermore, several workers with long-term exposure to maneb have developed Parkinsonism, possibly as a result of manganese accumulation.6. Legislation to control the quality, sale and distribution of these products exists, but hazardous counterfeit pesticides have made their way on to the market. [9] indicates that 29.2% of farmers are spraying tomatoes after harvest which can lead to food poisoning or chronic exposures. Table 1. They enter the country through illicit pathways at porous borders. The method used to identify mancozeb residues was adapted from Eurofins Agroscience. During their study, the scientists led by Dr. Deogratious Ssekimpi, the Executive Director (UNACOH), randomly bought tomatoes from market vendors and farms, which were taken to the Directorate of Government Analytical Laboratory (DGAL), for analysis for the presence of pesticide residues. Mean Concentration of Mancozeb Per Sampling Location. Biocides1.com is the international website for the worldwide Biocides Industry. The researchers conducted the study in the following districts; Kampala, Sembabule, Wakiso, Kayunga, Rakai, Bushenyi, Ntungamo, Kamwenge, Masindi, Nebbi, Adjumani, Kitgum, Gulu, Kapchorwa, Kumi, Pallisa, Budaka and Bugiri. Some farmers used more than the recommended dosages because they assumed that some of the products had been diluted prior to sale. It is therefore important to generate scientific evidence for action to minimize impact of human exposure to dithiocarbamate fungicide residues in food and build institutional capacity for routine surveillance of chemical contamination in food. An in-depth review of Uganda’s Pesticide Registration and Enforcement Policies revealed that the registration statute only went into effect in 1994, thus explaining the paucity of available registered compounds. This study assessed the level of dithiocarbamate residues in tomatoes acquired from 20 farmers and 25 … In Uganda, there is inadequate scientific evidence to support interventions of the whole lifecycle of chemical management, including specific categories like dithiocarbamates. Furthermore, the sample preparation technique based on acid digestion to liberate CS2 does not distinguish between the subclasses of dithiocarbamates; if another subclass apart from mancozeb was present, a false positive would be registered.20 If more than one subclass were present, a higher concentration would be recorded. Varieties for Tomatoes in Uganda There are many varieties of tomatoes on the market including the following: Money maker. Ten districts from different agroclimatic zones were selected for the survey. Contamination from Homes and Health Centers. The peaks were confirmed with NIST/EPA Mass Spectral library. The data was analyzed using Microsoft Excel (Redmond, USA) and IBM SPSS v21 (Armonk, USA). Available data indicates that the importation of pesticides into Uganda is on a significant rise, yet it comes along with various health risks for both farmers and consumers.
