Вплив систем землеробства та обробітку грунту на основних шкідників пшениці озимої

Abstract

The intensification of agriculture has a number of negative consequences, and the conservation of land resources during their active exploitation is an important problem nowadays, paying attention to the ever-growing food increase necessity. The world organic farming practice shows that we are very limited in the agricultural crops pests regulation. Artificial natural enemies increasing and the landscape altering to enhance biological control are not popular solutions and have contradictory efficiency. Monitoring of the winter wheat entomocomplex number was carried out according to conventional methods. It was performed at 48 plots, where 12 variants were placed in 4 replicates during 2019 - 2021. The article contains the research results show that farming systems have a significant impact on the main winter wheat pests, and that they can control the ecological system at the level of the economic harm threshold. The way the soil was treated did not change the number of Schizaphis graminum R., Eurygaster integriceps P., and Oulema melanopus L., while chisel cultivation of 20–22 centimeters provided regulation of Anisoplia austriaca H. and Haplothrips tritici Kurd number way more below the dangerous level for years of observation. Whenever the soil was treated to a depth of 6-8 centimeters, the number of these pests increased significantly and varied from 2.0 ind./m2 to 14.4 ind./m2. Therefore, this data shows the efficiency of insecticidal winter wheat treatments multiplicity reduction in an ecological system without the risk of crop loss due to the plant damaged by pests in combination with chisel soil cultivation.
