Еffictiveness of insecticides in crops sinapis alba

On crops of white mustard on sod-slightly podzolic soil with a humus content of 2.6%, pests were registered: pests of beetles, bugs, and aphids. High efficiency of Sumi-alpha, EC was revealed with a consumption rate of 0.2 l/ha on the 20th day after treatment, the effectiveness against flea beetles, rape flower beetles, bugs and aphids was 92.6%, 93.4%, 97.5% and 98.5%, respectively.

The effect of biologies on calega orientalis pests

On sod-weakly podzolic soil with a humus content of 2.6% that is in the Vologda region the pests such as striped, moth-like sitona, clover seed-eaters, various bedbugs and fleas were registered on Galega orientalis crops. A fairly high efficiency (85.2-90.4%) of the bitoxibacillin (BTB), P biologies against pests with a consumption rate of 4 kg/ha was established. The efficiency of dendrobacillin, P biopreparation with a consumption rate of 4 kg/ha was 62.5-87.6 %.

The dynamics of number, indices of productivity and economic use in the breed populations of dairy cattle

The article presents the results of monitoring the number of livestock, the indices of dairy cows productivity and the period of their economic use in the populations of Ayrshire, Holstein, Kholmogory, Black and White, Yaroslavl breeds in all categories of farms of the Vologda region. Based on the data from yearbooks on breeding on dairy cattle breeding farms of the Russian Federation the dynamics in the number of evaluated cattle and cows according to their breed populations for 2012-2016 has been defined.

Phytophagous in seed crops of galega orientalis in the Vologda region

Main phytophagous species belonged to the families of Coleoptera, Heteroptera, Homoptera, Lepidoptera are determined on seed crops of Galega orientalis on the sod-alsopozoriti soil. Longstanding research has established the influence of weather on the population dynamics of the pest and high efficiency of decis and bitoxybacillin of 85.5-95.5 %.
