БИОЛОГИЧЕСКАЯ ЭФФЕКТИВНОСТЬ НОВОГО МИКРОБИОЛОГИЧЕСКОГО ПРЕПАРАТА ПРОТИВ ОБЫКНОВЕННОГО ПАУТИННОГО КЛЕЩИ (TETRANYCHUS URTICAE KOCH) В СЕМЕЧКОВЫХ ПЛОДОВЫХ САДАХ

Abstract

The article substantiates the results of experiments to identify the effectiveness of the microbiological drug Bioslip BV (Beauveria bassiana) against spider mites, which cause harm in pome fruit orchards of Uzbekistan. In the experiments, the preparations Bioslip BV (Beauveria bassiana) 2.0 l/ha and Bioslip BT (Bacillus thuringiensis) were used. (toxin crystals in 1 g) (1.0 l/ha) as a result of the treatments introduced. After applying Bioslip BV (Beauveria bassiana) 2.0 l/ha, the biological efficiency was 44.2% on the 3rd day after application of the drug, 72.3% on the 7th day, 72.3% on the 14th day, and 60.2% on the 21st day. Bioslip BT is a powder of a microbiological preparation based on (Bacillus thuringiensis). (toxin crystals in 1 g) (1.0 l/ha) as a result of application the effect was 86.7% on the 3rd day after treatment, 85.8% on the 7th day, 88.9% on the 14th day and 87.5% on the 21st day.
