- W4364375538 abstract "Goal. To investigate an efficacy of the insecticides Aktelik 500 ЕС, (pyrymyphos-methyl 500 g/l), Calipso 480 SС (thiacloprid, 480 g/l), Proclaim 50 SG (emamectyn benzoat, 50 g/ kg), Movento 100 SC (spirotetramate, 100 g/l), Exirel, СЕ (cyantraniliprole, 100 g/l) and bio products Actofit, EC (aversektyn С, 0.2%), bitoxybacilyn — BTU, (insecticide), (Bacillus thuringiensis. endospores, endotoxyn, exotoxyn) and Lepidocyd-BTU, (insecticide), (Bacillus thuringiensis var. Kurstaki, endospores, endotoxyn) on a reduction of a number and a harmfulness of cherry fruit fly (Rhagoletis cerasi L.) it impact on yields in industrial cherry orchards.
 Methods. A field method, in the industrial orchards in educational production department of university. A type of cherry trees — Regina and Alfa. Planting scheme — 4.0 × 5.0 m. Year of planting — 1996. Crown shape — sparsely (improved) — tiered. Rootstock — antipka. Phases of plant development at application timing — «fruit development, (fruits about 90% of the final size)» (BBCH 81) and («fruits ripening phase») (BBCH 85). Soil — shallow, low — humus dusty — loamy podzolic leached black soils: humus content — 1.3—2.5%; pH 4.8—5.2; mobile compounds Р2О5 — 130—180 mg/kg and К2О — 8.9—9.2 mg/kg (by Chirikov method). The measures for care of the experimental site — loosening a soil in the stem strips during the growing period, an application of organic and mineral fertilizers, a pruning, a splaying of grass between the rows (row spacing), a protection from pests and diseases. The technical effectiveness of applications was determined in different rates against blood-red aphids and their impact on yields in commercial apple orchards. Calculations were made according to generally accepted methods in in horticulture, plant protection and entomology.
 Results. The use of insecticides Aktelik 500 ЕС, Calypso 480 SС), Proclaim 50 SG, Movento 100 SC Exirel, СЕ against cherry fruit fly helped to decrease number of pests on 91.4—98.9% — 93.7—97.6% accordingly. It allowed to obtain a high — grade cherries product with a yield of 1.7—1.9 times and 1.4—2.1 times higher comparing to control. The outcome of non-standard products did not exceed 0.4—0.6% compared to 34.9—44.3% in the control (water treatment). The efficacy of bio products was 32.9—40.4%. It confirms their low efficacy against this pest.
 Conclusions. The use of insecticides Aktelik 500 ЕС, Calypso 480 SС, Proclaim 50 SG, Movento 100 SC, Exirel, СЕ allows to achieve high efficacy of cherry fruit fly control in industrial plantations, to manage it number and population during whole month (the period of larva development). A limitation of pest number in cherry orchard by using the studied treatments provided a yield increase and a marketable quality of the obtained fruit products." @default.
