BIOLOGICAL EFFECTIVENESS OF A NEW MICROBIOLOGICAL PREPARATION AGAINST THE COMMON SPIDER MITE (TETRANYCHUS URTICAE KOCH) IN SEED GARDENS
The article found that the microbiological preparation Bioslip BV (Beauveria bassiana) at a consumption rate of 3.0 l/ha has a
strong effect on spider mites that cause harm in pome orchards. Accounting for the effectiveness of the microbiological
preparation was carried out on the third-seventh and fourteenth-twentieth days. Bioslip BV (Beauveria bassiana) 3.0 l/ha and
Bioslip BT powder (Bacillus thuringiensis) were taken for the experiment. (toxin crystals in 1 g) (1.0 l/ha) were analyzed from
the 3rd day of treatment. According to the results of the studies, after the application of Bioslip BV (Beauveria bassiana) 3.0 l/ha,
the biological efficiency was 44.2% on the 3rd day after the application of the drug, 72.3% on the 7th day, 72.3% on Day 14
73.9% on day 21 and 60.2% on day 21. Bioslip BT is a powder of a microbiological preparation (Bacillus thuringiensis). (toxin
crystals in 1 g) (1.0 l/ha) found to give an effect of 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
