The note contains information on a condition of crops winter grain on fields of the Razdolnensky area, namely results of inspection of fields on existence of myshevidny rodents.
From myshevidny rodents the public vole is most widespread in the Razdolnensky area, the individual centers of moving of a kurganchikovy mouse are noted on lands of Ziminsky village council.
Due to the small sizes of a body thermoregulation at myshevidny rodents is poorly developed, therefore the temperature at them changeable and fluctuates from 300do 400S. For maintenance of necessary temperature more energy, than a warm-blooded animal therefore they differ big insatiability is necessary for rodents. So, the weight of the green forage eaten by the vole in days, makes 100-350 % of weight of her body (10-<st1:metricconverter ProductID = 30 g w:st = on> 30 g </st1:metricconverter>). The weight of the green forage eaten during this time by a cow, for example, makes only 5 % of weight of her body.
In a food of voles the first place is occupied by green juicy forages, only in a cold season of a mouse eat seeds of cereal cultures and weeds.
Among rodents of the vole the most prolific that is caused by their early puberty. In a year they are capable to give to ten dung, on 5-6 little mice in everyone. If on <st1:metricconverter ProductID = 1 hectare w:st = on> 1 hectares </st1:metricconverter> crops of winter wheat in November was three inhabited colonies (on one pair adult voles in everyone), under favorable conditions in June of the next year can be about six hundred.
In the area crops winter grain, a rape, long-term herbs, pastures on the area of 43,2 thousand hectares are surveyed. The fields occupied by rodents, on 13,2 thousand hectares, from them under crops of the winter grain – 11,1 thousand hectares, long-term herbs – 0,9 thousand hectares, other – 1,2 thousand hectares are processed. A biological method applied on 1,2 thousand hectares. From chemical preparations used grain baits of Rodenfos.
It is necessary to mean that green leaves of winter crop and a lucerne contain a large number vitaminaK – natural antidote from anticoagulants (of century brodifakum, bramadolin, difinacin), and therefore at their application repeated processings are required.
At a regional seminar on the organization of works with pesticides to farmers recommendations about pest control and diseases of field cultures and long-term plantings were made. The special attention was given to chemical and biological measures of fight and observance of safety regulations at work on protection of plants against rodents.
