The Laboratory of Analytical Chemistry of Pesticides was founded in 1956. Until 1978, it was headed by a leading scientist in the field of analytical pesticide chemistry, Doctor of Chemical Sciences E.S. shaggy In 1978-1992, the laboratory was headed by Doctor of Agricultural Sciences V.M. Kavetskyi, 1992-2015 - doctor of agricultural sciences, professor L.I. Bagel   

Laboratory staff: candidates of agricultural sciences: T.P. Panchenko, O.G. Vlasova, L.M. Chervyakova, research associate M.D. Zacerklyana

Main areas of research:

 Rationale for the rational use of pesticides in modern land use systems as an element of preserving the optimal and high-quality state of agrocenoses (according to the criterion of residual amounts of pesticides), which allows obtaining a high-quality harvest and ensuring the environmental safety of the environment.

 Development of methods and ways of determining individual active substances and their combinations in various matrices (objects of agrocenoses, soil, poisoned seeds, preparative forms of plant protection products).

 Studying the dynamics of pesticide detoxification in agrocenoses and determining the numerical criteria of the process.

Development of methods of environmental assessment of agrotechnologies of chemical protection of agricultural crops (determination of the risk of pesticide use according to AETI) for the purpose of forecasting, prevention of environmental risks and reduction of negative impact on the environment.

Theoretical substantiation of the formation and improvement of the range of insecticides in order to increase their effectiveness, ecological safety, as well as to prevent the formation of resistant populations in the main pests of agricultural crops.

Justification of scientific principles of rational use of pesticides in integrated plant protection systems

Monitoring the sensitivity of natural populations of the main pests of potatoes and grain crops to insecticides, studying the insecto-acaricidal resistance of harmful and beneficial species of arthropods.

Study of the biological and physiological action and after-effect of insecticides of a new range on harmful insect species with simultaneous and sequential application of toxicants.

Main developments:

• A method of systematic analysis has been developed for the qualitative and quantitative control of pesticides used in the technologies of growing grain and fruit crops, sugar beet;
• The correlation between the polarity of pesticides (their physico-chemical properties) and the rate of their detoxification in agrocenoses was established and formalized, the possibility of using the dipole moment and the detoxification rate constant for the ecotoxicological screening of pesticides in agrocenoses was proved;
• A model for assessing the risk of pesticide use according to the Agroecotoxicological Index (AETI) was created and built on a 10-point scale, which takes into account the properties of pesticides, the seasonal load and the tolerance of agrocenosis, and makes it possible to choose the optimal protection option for each agricultural crop.
