“…Contact to pesticide residues causes health effects that differ with the characteristics of the pesticide and the method of action (Kariathi, Kassim, & Kimanya, 2017). Unsuitable usage of pesticides brings consequences worldwide or local, transient or permanent, or short-term (acute) or long-term (chronic).…”

“…Pesticide residues in agricultural products can be reduced by washing the product with water (Putri, Sunarti, & Suhartini, 2016) which flows several times, then soaked in water for one hour. According to Bouchard et al (2011) and Kariathi, Kassim, & Kimanya (2017), the example of treatments that can affect pesticide residues extensively in vegetables include washing, peeling, and cooking. Such processes usually decrease pesticide in the vegetables so that lowering the risk of human contact with these residues (GEMS/Food & Codex Committee on Pesticide Residues, 1997).…”

Journal of Agricultural Sciencewww.agrivita.ub.ac.id Plant Origin (FFPO) in the horticulture group. According to Norton, Sanchez, Clarke-Harris, & Traoré (2003), there is a quick-rising in the production and export of horticultural products in many developing countries. Data have shown that from 1970 to 2002, fruit and vegetable production in developing countries increased almost fourfold from 256 to 960 million metric tons, while exports more than triplicated from 1.9 to 6.5 million metric tons. The stimulus for a request for such highvalue commodities include income increase, transportation costs decrease, and, in some cases, improved market access. Production for export is often fostered as a means of producing foreign exchange, boosting incomes to producers, and giving employment to the poor in a rural area. As for the importing countries, they get an advantage from bigger product stocks that generally have been limited and costly in the off-season.In Indonesia, there were five seasonal vegetable commodities with the largest production in sequence, namely shallots (1.4 million tons), cabbage (1.44 million tons), large chili (1.21 million tons), potatoes (1.16 million tons), and ARTICLE INFO

The present study consisted of evaluation of cultural practices and pesticides contamination level of tomato in some gardening sites in the region of Boucle du Mouhoun (Burkina Faso). A survey of phytosanitary practices among 30 producers was carried out at the Di and Dedougou sites. The pesticide contamination level of tomatoes collected was determined by the QuEChERS method. The survey revealed a low level of literacy among producers (60%), an increased use of pesticides without adequate protection materials, non-compliance with prescribed doses, use of unregistered pesticides (28%) and poor management of packaging. Chromatophic analysis of the samples detected 16 active substances predominantly organophosphorus (62%). 62.5% of detected compounds (Omethoate, Parathion methyl, Diazinon, Methydathion, Pyridaphethion, Pyrimiphos methyl, Alachlor, 2.4 DDT, lindane, permethrin and Imazalil) are not authorized by the CSP. Among authorized compounds, Dimethoate, Malathion, and Cypermetrin contamination levels higher than the MRLs have been observed. These results confirmed risks of environment contamination and sanitary of farmers and consumers linked to their exposure and consumption of tomatoes. Measures should be taken to raise awareness among market gardeners of good pesticide use practices and the adoption of alternative methods to pesticides to protect environment, gardeners and consumers health.

“…In an effort to control tomato pests and diseases, small scale farmers rely heavily on synthetic chemicals (Nashwa and Abo-Elyousr, 2012;Asante et al, 2013). However, concerns have been raised regarding contamination of the produce and pollution of the environment by the pesticides, health hazards to producers and consumers and the risk of elimination of non-target beneficial organisms from the ecosystems (Business Daily, 2015;Ndakidemi et al, 2016;Mustapha et al, 2017;Victoria et al, 2017). In export markets, misuse of synthetic chemicals poses problems with market access due to high residue levels (Muthomi et al, 2016).…”

Tomato Production Characteristics, Biotic Constraints and their Management Practices by Farmers in Bungoma County, Kenya

Tomato (Solanum lycopersicum L.) is an important crop in Bungoma County, Kenya. Its production is constrained by arthropod pests and diseases which make farmers rely heavily on synthetic chemicals to control them. To support the development of effective integrated pest and disease management strategies on tomato, a survey was carried out in Sirisia, Bumula and Mt. Elgon sub-counties. A total of 90 randomly selected farmers in the region were interviewed using a structured questionnaire. Data collected included demographic characteristics of farmers, tomato varieties, farm size, prevalence of pests, diseases and their management practices. Majority of the respondents were male with 89.7% in Mt. Elgon. Most of the respondents had primary education. The varieties of tomato grown were Rio-grande, Kilele, Carl-J, Money-maker, Safari and Onyx. The average farm size ranged from 0.25 to 1.0 hectare with 80.4% in Sirisia. Most prevalent pests affecting tomato were Frankliniella occidentalis (58.6%) and Bemisia tabaci (35%) while the most reported disease was Ralstonia solanacearum (75%). The chemicals used against pests included Imidacloprid (24.4%), Alpha-Cypermethrin (20.7%) and Lambdacyhalothrin (20%). Farmers controlled diseases using Metalaxyl-M, Mancozeb, Propineb and Carbendazim. Out of the total ninety respondents in the region, only 2.4% in Sirisia used bio-pesticides. At least 60%, 22% and 20.7% of respondents in Bumula, Sirisia and Mt. Elgon, respectively used more than one chemical. About 10% of respondents in Bumula and 6.9% in Mt. Elgon applied chemicals twice a week. In Sirisia, about 53.6% reported that the chemicals used effectively controlled the pests and diseases compared to Bumula (61%) and Mt. Elgon (58.6%) who reported that they were ineffective. The main source of advice on crop protection was Agrovet shops. The findings revealed that pest and diseases limited tomato production in the region. The study therefore recommends increased awareness on proper use of chemicals and use of safer alternatives such as bio-pesticides to reduce on pesticide residues and the production cost. Future studies on the level of synthetic chemical residues in tomatoes produced in the region should be conducted.
