“…According to the results in Table 3, the half-lives of fosthiazate in tomatoes were 4.81 ~ 5.37 days, and the half-lives of fosthiazate in cherry tomatoes were 5.25 ~ 5.73 days, which showed that fosthiazate can be quickly degraded in tomatoes and cherry tomatoes. The results also showed that the half-lives of fosthiazate in three regions of Guangdong, Guangxi and Yunnan were different, which may be related to the weather, temperature, soil environment and other factors (Li et al, 2016;Li et al, 2015). The statistical analyses results for the signi cance of the half-life demonstrated that the dissipation rates of fosthiazate in tomatoes and cherry tomatoes were different (Fig.…”

In this study, the safety and risk of fosthiazate as a nematicide against root-knot nematode in tomato and cherry tomato were evaluated. The dissipation and residue of fosthiazate for 28 days in tomato and cherry tomato were determined and studied by HPLC after simple, rapid pre-treatment. The mean recovery was 83.79 ~ 94.18%, and the relative standard deviation was 3.97 ~ 7.40%. Results showed that the halflives of fosthiazate in tomato (4.81 ~ 5.37 days) were signi cantly lower than that in cherry tomato (5.25 5.73 days). At the pre-harvest interval (PHI) of 21 days, the residues of tomatoes and cherry tomatoes were 0.032 ~ 0.046 mg/kg, which were lower than the maximum residue level established in China. The potential risks of fosthiazate exposure through the dietary intake of tomatoes and cherry tomatoes to different populations were also studied. According to the results of dietary risk assessment, the residual levels of fosthiazate were within the acceptable range of long-term dietary risk in different populations in China within the sampling interval of 21 days after the application of pesticide. Our results show that fosthiazate as a nematicide in the eld control of root-knot nematode has high safety and low risk, and can provide a reference for the safe and reasonable use of fosthiazate as a nematicidein in the eld.

“…14 found that the half-life of abamectin was 1.02 days in strawberry. Under the conditions of 1.5 times recommended dosage, the half-lives were 2.1–3.4 days for carbendazim in tomato 15 . In recent study, the half-life of difenoconazole was 3.6 days following one time application in strawberry 16 .…”

In this study, the effects of fruit bagging on residue behavior and dietary risk for four pesticides (abamectin, imidacloprid, carbendazim and difenoconazole) in apple were investigated. The dissipation behavior of four pesticides were assessed after spraying on three occasions with the first spray at 2 months before harvest and the subsequent sprays at 10-day intervals at recommended doses of 5.4, 45, 135 and 975 g. a.i.ha−1, respectively. The dissipation experiment results demonstrated that apple fruit bagging reduced the initial deposits of four pesticides from 72.2% to 95.3%, prolonged the half-lives from 50.4% to 81.1%. The ultimate residues of abamectin, imidacloprid, carbendazim, and difenoconazole in bagged apple were far below the residues of unbagged apple. The dietary risks of four pesticides were assessed according to the ultimate residues and acceptable daily intakes (ADIs). The hazard quotient (HQ) were 0.013% to 43.415% for different pesticides. Fruit bagging reduced the HQ of four pesticides from 29.7% to 94.8%. Fruit bagging reduced the dietary risk of four pesticides in apple.

“…The regulation of these products is important because a large part of the agricultural defensives used by rural producers offer a high degree of toxicity as can be seen in Table 2 and Another relevant factor is the use of products that have already been banned and are still commercialized due to their relatively cheap price, as is the case with carbendazim and dietofencarb (LI et al 2016), dichlorodiphenyltrichloroethane (DDT) and, the hexachlorocyclohexane isomers banned from India and other Asian countries (MEFTAUL et al 2019), and methyl bromide that was expected to be banned by 2005 according to the Montreal protocol for causing depletion in the ozone layer (SANDE et al, 2011).…”

Resumo: O tomate (Solanum lycopersicum L.) é uma das hortaliças mais cultivadas do mundo. A China representa cerca de 25% de toda a produção mundial, desta forma existe uma dependência e uso constante de defensivos agrícolas na cultura do tomate. A aplicação de produtos químicos proibidos em diversas partes do mundo tem como efeito colateral um grande impacto na saúde humana e no ecossistema, sendo necessário adotar outras estratégias de prevenção de doenças. Outra forma de combate às doenças do tomateiro é a utilização de microrganismos como forma de controle biológico, considerado uma alternativa aos defensivos agrícolas e antibióticos com maior sustentabilidade e menor toxicidade. Neste trabalho, os defensivos agrícolas mais utilizados pelos produtores foram Piraclostrobina, Mancozebe, Oxicloreto de Cobre e derivados do DDT. Para os antibióticos, Estreptomicina e Oxitetraciclina foram os mais utilizados, enquanto Bacillus spp. e bactérias do ácido lático (BAL) foram os microrganismos mais citados como forma de controle biológico. Por fim, os principais fitopatógenos do tomateiro foram Xanthomonas spp., Clavibacter michiganensis subsp. michiganensis e Ralstonia solanacearum. Os objetivos deste trabalho foram identificar os principais tipos de defensivos agrícolas, antibióticos e gêneros de microrganismos utilizados no controle de doenças do tomateiro e comparar seu impacto na saúde humana e no meio ambiente. Palavras-chave: Doença do tomateiro, Fitopatógenos, Bactéria ácido láctica, Defensivo agrícola, Controle biológico.
