Results of testing bioinsecticide Metawhite against soil pests of sunflower

Abstract

Sunflower is often susceptible to attack by a wide range of pests and diseases, which in some years can significantly reduce the yield of this crop. A fundamentally different method of limiting the number of insect pests is the use of bioinsecticides based on entomopathogenic microorganisms. Most of the bioinsecticides currently produced are designed to control leaf-eating insects. Information on the effect of these preparations on soil pests, in particular on polyphagous ones, is extremely scarce.

Research work on testing the drug Metawhite was carried out in 2020, on the sunflower fields of the agricultural company SRL „Bardar-Agro”, Bardar, Ialoveni district. The soil was treated with various doses of Metawhite before sowing, on April 16, 2020.

The field plot experiment was carried out in quadruple repetition. The plot size is 10 rows with a distance between rows of 0.7 m and a row length of 10 m. Thus, the area of one plot was 70 m2.
