CHEMICAL PROTECTION OF WINTER WHEAT FROM WHEAT TRIPS IN THE RIGHT-BANK FOREST STEPPE OF UKRAINE

Abstract

The seasonal dynamics of the monovoltaic oligophagus of cereals – wheat thrips was investigated in the Right-Bank Forest Steppe of Ukraine during 2017–2019. This species has been dominant among thrips and other pests. The development of the phytophage was determined by the meteorological conditions of the studied years. The most favorable for the pest was 2018, when the highest number of the pest was recorded (930 specimens / 100 swings the net in the second decade of May). The effectiveness of insecticide use was studied against a significant amount of pest. Two pyrethroids (Karate Zeon 050 CS, Decis f-Suite 25) and one neonicotinoid (Actara 25 WG) were included in the study. High efficiency of the preparations is shown with a considerable number of phytophages. The highest efficiency had the Karate Zeon 050 CS (0.2 l / ha) against imago and thrips larvae.
