Neonicotinoids against sucking pests on winter wheat stands in the Forest-Steppe Zone of Ukraine

Abstract

Saturation of crop rotation with grain cereal crops (corn, winter wheat) leads to the creation of favorable conditions for the development of sucking pests and, consequently, increasing of their density of population and harmfulness on winter wheat crops. The comparative evaluation of the effectiveness of neonicotinoids against the group of sucking pests (Sun pest (Eurygaster integriceps), wheat aphids, thrips) on crops was done in 2016-2017. Insecticide Engeo 24.7% SC was the most effective against the Sunn pest. His maximum technical efficiency reached 100.0% and was obtained on 7th and 14th day after treatment. The most effective for spraying against aphids were Engeo 24.7% SC and Actara, 24% SC, that shown 99.7% and 98.3% reduction of aphids number on 7th day compared to the control respectively. The application of investigated insecticides significantly reduced the population of aphids, trips and Sun pest, that results in increasing in quantitative and qualitative indices of winter wheat yield
