Warm winter threatens the harvest of the invasion of pests and diseases

agricultural centre began to inform the farmers in the southern regions of early activation of locusts. “The hot weather of summer 2019 contributed to the development and propagation of particularly dangerous pests gregarious locusts, occupying an area of 15.5 thousand hectares. Abnormally warm winter have contributed to the survival of wintering their stock – the eggs in the egg capsules. Spring is projected for early hatching larvae”, – stated in the message Department.

Asian locust lives in the swamps – flooded floodplains, covered with thickets, explains the Director of Institute of protection of plants Vladimir Alekhine. During the flooding of part of the larvae die. But this year, the spill will not, that is, for the survival of locusts will be created ideal conditions. Warm, dry winter also “cherished” mice, bugs bugs and some other pests who will wield and the more Northern areas of the country. According to the expert, if you do not take any protective measures, potential yield losses are estimated at 30% of the total. But the share of pests account for only 10%. Another 8% “eat” plant diseases, 12% to weeds. But the South of the country is traditionally located in the area of special risk, due to longer period of damage. In addition, the SFD farmland occupy 80% of the area of the region.

Theoretically, the locusts can cause great harm to the crop. But we should not exaggerate its capabilities – the insect does not extend beyond the southern regions. “Yes, and not-so-large volumes in question, so this could lead to disastrous consequences” – soothes the Vice-President of the Russian grain Union Alexander Korbut. Last year in the Rostov region has already been observed, the invasion of the saRanchi. However, the region managed to gather 7% more yield in 2018.

30% can be crop losses due to pests, if not in time to take protective measures

Warm snowless winter may be a prerequisite for the active development of not only locusts, but also other epidemics, according to the President of the National Union of agricultural insurers the Roots of biggov. Besides, in the autumn of last year in practically all regions of the earth sowing of winter crops took place in conditions of low moisture content in the soil, which could lead to weakening of the plants, and their lower resistance to microorganisms, the expert adds. According to him, over the past four years on the risks of plant in the framework of a unified system of agricultural insurance the agricultural insurers paid more than 2 billion rubles. However, mainly the risks associated with drought, waterlogging and risks for winter.

Fears of drought, pests and diseases, caused by a warming climate are far-fetched, the Director all-Russia research Institute for agricultural meteorology (research Institute of skhm) Valery Long-Trach. The locust threat, regardless of, aktiviziruyutsya it two weeks later or two weeks earlier. And today to predict any anomaly more or less it fails to anyone. Despite the snowless winter, the damage to the crops was in the range of average. And no obvious changes in the terms or technologies of possible bad weather during the agricultural season will entail, the expert believes.
