Disorientation of the plum moth (Grapholita funebrana Treitschke) under the conditions of chemical protection of the garden was carried out using dispensers (Z8DDA, 16.7 mg) produced by ZAO Shchelkovo Agrokhim. Dispensers were placed at a tree trunk at a height of 1.5 - 2 m with an application rate of 500 per hectare. The study was carried out on three plots of a 1 ha plum orchard: a plot with chemical treatments and with disorientation, an area with chemical treatments, without disorientation, and an area without chemical treatments and without disorientation. The effectiveness of disorientation at a high abundance during the flight peaks of the second and third generations of the pest ranged from 100 % to 92-93 %. The effectiveness of disorientation, together with the chemical protection of the garden in comparison with untreated area, showed higher results - in the first two months, the efficiency ranged from 100 to 98 %, and during the periods of the 2nd and 3rd flight peaks of the pest (with a flight intensity of 136 - 120 individuals per trap) did not fall below 96 %. |
