Introduction. From the evaluation of the positions of residual quantities of pesticides, the hygienic safety assessment of imported food products is most relevant under the current agreement on a free trade zone between the EAEU and the Socialist Republic of Vietnam, as well as in connection with a large list of chemical plant protection products used during the vegetation of crops. The purpose of the study. Rating the level of residual quantities of pesticides in samples of selected food products produced in Vietnam is the purpose of the study. Research objectives. To quantify 42 active ingredients of pesticides (and their metabolites) in samples of rice grain, dragon fruit (pitahaya), avocado, mango and banana (fresh and dried) are the research objectives. Material and methods. Multicomponent and individual methods based on LC and GC with MS-detection and FLD were used to identify active ingredients of pesticides. The sample preparation procedure with QuEChERS technology was used for the multi residues determination of the 40 compounds. The determination of avermectins (abamectin and emamectin benzoate) was carried out after the conversion of substances into fluorogenic derivatives. Results. Residual amounts of tebuconazole (rice - 0.53 ppm, mangoes - 0.26 ppm, avocado - 0.15 ppm), fludioxonil (rice - 0.017 ppm), imidacloprid (dried mangoes - 0.01 ppm), carbendazim (dried mangoes - 0.011 ppm) were identified in single samples No residual avermectins have been identified. The content of substances in the analyzed samples of dragon fruit (pitahaya) did not exceed 0.01 ppm. Discussion. The results obtained in the work are compared with the data of the annual pan-European and national monitoring, information on which is publicly available (2017), including imported goods, according to which rice and dragon fruits as objects of monitoring are given increased attention. Conclusions. The safety of certain types of food products imported from Vietnam is shown by the content of residual quantities of pesticides.

Disappearance of Azoxystrobin, Cyprodinil, and Fludioxonil Residues on Tomato Leaves in a GreenhouseThe objective of this work was to estimate the disappearance parameters of azoxystrobin, cyprodinil and fludioxonil initial deposits, active ingredients of Amistar 250 SC, and Switch 62,5 WG, at present, commonly used for the protection of fruits and vegetables against diseases of fungal origin. The tests were carried out on tomato plants grown in commercial greenhouses sprayed with homogenous 0.1% aqueous solution of these plant protection products. It was found that on tomato leaves azoxystrobin, cyprodinil, and fludioxonil residues dropped by half on average within 13, 9, and 31 days after treatments, respectively. Therefore, in conditions of high infection pressure, there is a need to repeat the fungicide application but not earlier than 10 days after previous application of Amistar 250 SC and Switch 62,5 WG.

It is well known that emulsifiable concentrates (EC), besides good properties have problem with a high solvent content thus are not environmental friendly and can cause problems for users. The interest in developing oil-in-water emulsions (EW) instead emulsifiable concentrates is increasing due to toxicological problems with solvents. Oil-in-water emulsions can reduce phytotoxicity, ecotoxicity and dermal toxicity, have a higher flash point than EC and are safer in transport and storage; also EW are more compatible with water based SC formulations for blends of active ingredients. Plant protection often includes the use of some pyretroides as active ingredients, for example Cypermethrin, alone or combined with Chlorpyrifos. It is a very old product which is formulated as EC formulation. In this study oil-in-water emulsion (EW) was developed with the same active ingredients. The EW formulation was tested and the results show that it was stable and therefore could be used in plant protection.
