Authors of article recommend protective measures during the winter and spring period of 2008 on crops of winter crops.
RECOMMENDATIONS
Weather conditions of January of the current year promote further injuriousness of myshevidny rodents in crops of winter grain crops.
On specific structure the greatest distribution have: the ordinary vole, house and wood mice, and in the centers of the Black Sea and Lenin areas – a kurganchikovy mouse.
For the purpose of crop preservation, we recommend to carry out continuous inspections of agricultural holdings constantly. At achievement of an economic threshold of injuriousness (EPV) of 2-3 colonies on hectare, 7-10 inhabited holes in a colony to hold protective events against myshevidny rodents on a rape, long-term herbs, on roadsides of roads not to allow migration them in crops of grain crops.
Protective measures carry out preparations: Rodenfos, Brodisan, Ratindan, Baktorodentsid – 3 gr/in a mink, Storm briquettes – 1,5 kg/hectares.
In January and February thaw, a food of larvae of the grain ground beetle, which bulk, for frosts will proceed, fell to deeper layers of earth and is in the second age. Renewal of injuriousness it is necessary to expect at temperature above 0oS, at night. Processings carry out at number of the grain ground beetle of 0,5-1 pieces/sq.m. On weak crops, injuriousness of the wrecker can look in the form of a continuous food in ryadka, without education pleshin.
During the spring period in a steppe part of the Crimea, on winter, ochagovy injuriousness podgryzayushchy a scoop is possible. A signal for carrying out protective chemical measures is the threshold of injuriousness of 2-3 copies of sq.m.
In fight against these wreckers it is necessary to use the following preparations: Diazinon k.e., Diazol century e. 1-1,5 l/hectares, Sherp, Arrivo-0,24-0,32 of l/hectare and others. But lateral mixes of fosfororganichesky and piretroidny insecticides in polovinny dosages, with addition of 3-4 kg of urea are most effective. To apply them it is better in the evening when caterpillars eat.
Sharp differences of temperatures, availability of drop moisture will promote during the spring period to emergence of mealy dew, a root gnily, brown sheet rust, septorioza, gelmintosporioza on the winter. For improvement of plants, the soil, infection removal, it is necessary to carry out preventive processings fungicidami, taking into account a temperature mode.
At temperature + 7o-14os, it is necessary to use Fundazol with norm of an expense of 0,5 kg/hectares, at temperature +16-18os, to apply preparations: Bayleton of 25 % for item page – 0,5 kg/hectares, Rex Duo k.e. – 0,6 l/hectares, Impakt of 25 % of page to. – 0,5 kg/hectares, Alto Super k.e. – 0,4-0,5½/hectare and others.
To agricultural producers of all forms of ownership, after vegetation renewal, on the crops infected with diseases to carry out without fail, the combined processings fungicidami and herbicides. Together with fungicidami, it is necessary to carry out introduction of herbicides, since more developed crops grain and to their exit in a tube. Bakovye should prepare mixes directly ahead of processing, strictly observing safety measures.
We recommend the following lateral mixes:
Granstrar of 75 % (10 ml/hectares) + Puma Super m.v.e. (0,5 l/hectares) + Fundazol of 50 % for item page (0,5 kg/hectares):
Bazagran century of river (1,0 l/hectares) + Mitas of item page (4 úÓ/hectare) + Rex Duo k.e. (0,6½/hectare);
Cowboy of 40 % of century of river (60 ml/hectares) + Puma Super m.v.e. (0,5 l/hectares) + Alto 400SCv.k. (0,2 l/hectares);
Harmoni of 75 % for century of (7 g/hectares) + Monitor of 750 century of (0,013 g/hectares) + Impakt of 25 % of page of the item (0,5 kg/hectares);
Grodil Ultra 720 century of river (0,6 g/hectares) + Monitor of 750 century of (0,075 g/hectares) + Topsin of M of page of the item (kg/hectare) and others.
Untimely carrying out protective measures against wreckers of diseases and weeds can lead to loss to 30 % of a crop.
Only continuous carrying out inspections of fields and control of a fytosanitory condition of crops, and also timely carrying out protective measures will allow to keep future crop.
To heads of farms of all forms of ownership who have no agriculturists on protection of plants, we suggest to address to specialists of service of protection of plants of the republican and regional device (contact phones of State inspection of ARK 63-25-78).
L.Alekseev acting the chief of the State inspectorate for protection of plants, S. Kindruk, deputy chief, head of department of forecasts and fytosanitory diagnostics.
