Use of humic preparation for increasing the effectiveness of insecticides in chickpea cultivation

Abstract

The article presents the results of an experiment (2016—2019) to study the influence of humic preparation on the effectiveness of insecticides of various chemical classes. Phytosanitary monitoring, pests count before and after treatment were carried out in addition to calculating the biological efficiency of insecticides; the impact on chickpea productivity and nutrition regimen was considered against the background of the chemical protection system with the inclusion of the humic preparation BIO-Don10. Harmful objects are cotton budworm (Helicovera armigera Hb) and bean aphid (Aphis fabae). It was found that the pyrethroid class preparation is more effective against cotton scoop. The reduction in bean damage is 93.7%. The efficiency of organophosphorus compounds does not exceed 45.0% in view of the developed stability. The preparations under study showed high efficiency against bean aphid, the decrease in aphid numbers is 93.9 and 90.9% respectively. Humic preparation did not affect this indicator, but allowed to increase the saved crop on the option with pyrethroid by 46.4 - 56.0%, with dimethoate by 29.6 - 40.0%.
