Modern insecticidal control against sucking pests on winter wheat crops in the Central Forest-Steppe zone of Ukraine

Abstract

The article presents the results of modern insecticidal control against sucking pests on winter wheat crops in the Central Forest-Steppe zone of Ukraine. The aim of the article is to determine the technical effectiveness of insecticides of new classes of chemical compounds, as well as known insecticides and their preparative forms. Methods: the methodological basis of this study is: empirical (field experiments and observations; measurement of indicators of the object of study; theoretical (hypothesis formulation and formation of conclusions based on research results); statistical; mathematical. Results. Our task in 2023–2025 was to study the technical effectiveness of insecticides of new classes of chemical compounds, as well as known insecticides and their preparative forms. Over the years of research, we have found that when using insecticides, a sufficient level of effectiveness was achieved against cereal aphids and wheat thrips larvae. The use of all insecticides in a mixture with the addition of the adjuvant “Tandem” had a positive effect on protection against sucking pests on winter wheat crops, the technical effectiveness was at the level of 77.7–100%.However, it was most effective against all phytophages inthe variant using the adhesive “Tandem” with a consumption rate of 15 ml/10 l of water and the drug Engio 247 SC with a rate of use of 0.22 l/ha, technical efficiency reached the highest indicators – 92.8–100%. Conclusions. During the research years 2023–2025 in the Central Forest-Steppe zone of Ukraine, modern insecticides were effective against sucking pests on winter wheat crops: Aktara 25 WG, VG with a rate of use of 0.14 kg/ha, Karate Zeon 050 CS – 0.15 l/ha and Enzhio 247 SC, k.s. m.s. – 0.22 l/ha. The technical efficiency of the drugs was 72.4–90.5%. With the addition of the adjuvant “Tandem”, the efficiency of insecticides increased from 5.3 to 9.5% depending on the drug. The most effective against sucking pests was the drug Enzhio 247 SC with a rate of use of – 0.22 l/ha, both when used separately and in a mixture with an adhesive.
