Integrated protection of the Galega orientalis on sod-podzolic soil

Relevance. The Galega orientalis, growing in one place for many years in a row, accumulates many different diseases and insect pests in its agrobiocenosis and the seed productivity of the crop decreases, so comprehensive protection of crops is relevant.

Methods. The accounting platforms were laid on the experimental field of the Vologda State Agricultural Academy in 2012 on the Gale variety. The soil of the site is sod-slightly podzolic, medium loamy, with a capacity of the arable horizon of 20-22 cm and a humus content of 2.6%. Observations of diseases and pests were carried out during the entire growing season of the Galega orientalis from May to September once a decade. The collection of insect pests was carried out with an entomological net, based on samples in 10 strokes, which corresponded to the density of insects per 1 m².

Results. Diseases such as peronosporosis, powdery mildew and rust with an average number of 5-9 specimens per 1 m² were detected on Galega orientalis. The pests were dominated by nodule weevils of the genus Sitona, clover seed eaters of the genus Apion and grass bugs, with a number of more than 10 specimens per 1 m2. The integrated protection of Galega orientalis included weeding of experimental plots from weeds, spraying of crops from diseases in the phase of regrowth of the Galega orientalis with a fungicide — Falcon with a consumption rate of 0.6 l/ha and from pests in the budding phase of the culture — with a microbiological preparation Bitoxibacillin with consumption rates of 2, 3 and 4 kg/ha. A sufficiently high efficiency of the fungicide Falcon, CS (suspension concentrate) with a consumption rate of 0.6 l /ha — 80.9-91.7% — was established. The efficiency of Bitoxibacillin with a consumption rate of 4 kg/ha was 89.5-92.5%.
