In article it is said that crops of winter wheat are very important for processing from wreckers and diseases. Preparations, terms and doses of their introduction are given.
With a view of protection of crops of winter wheat from bolezyony, in particular from mealy dew which can remain from predecessors, it is very important obrabotat crops fungicidami.
For leaves of the bottom circle of winter wheat sushhestvuet disease threat septoriozy, defeats by a brown rust.
To warn yield losses from these bolezyony, it is expedient to carry out spraying of rasteyoniya by one of fungicidov: a viola 400, to. e. (0,15-0,20 l/hectares), a viola super, bajleton, impakt 25, tilt, the river duo, to. e. (0,5 l/hectares), falkon, to. e. (0,6 l/hectares), folikur BT, to. e. (1 l/hectare).
At crude weather, during wheat flowering, it is possible to expect distribution fuzarioza kolosa. Most effectively protects wheat from this illness and provides preservation of quality of grain processing of plants folikury BT (1 l/hectare), a viola 400 (0,15 l/hectares) or falkony (0,6 l/hectares).
As to protection of field cultures against wreckers, this year, probably, it is necessary to resort to measures for destruction of a bug of a cherepashka. Poyavleyoniye the centers with the increased number of this vrediyotel should be expected in a nalivaniye – molochyony ripeness of grain. At number of a bug of a chereyopashka of 2 larvae on sq.m it is good to carry out opryskiyovany wheat one of recommended below insecticides.
Processings are expedient for beginning at existence in population of a bug of 15 – 25 % of larvae of the third pokoyoleniye. The best results use of a two-homponentnoy mix from fosfororganichesky (Gives Bi-58 new, danady, bazudin, a rogor, fufanon) and piretroidny or other preparations (the actor, to de-tsis, karate, fastak, etc.) with polovinny normami their expense.
For protection against a corn and meadow butterfly in mass revival of their caterpillars, in the presence of more than 18 – 20 % of plants with yaytsekladka of the wrecker, we recommend to spray crops by one of insecticides: decis, to. e. (0,5 – 0,7 l/hectares), decis forte, to. e. (0,05 – 0,08 l/hectares), karate, to. e. (0,2 l/hectares), karate zeon, to. e. (0,2 l/hectares), sherpa, to. e. (0,32 l/hectares).
For receiving a seed material of bean herbs in a butonizatsiya – at the beginning of formation of beans it is important to carry out spraying of plants against kloyopov-slepnyakov (at number more than 15 – 20 osoyoby), fitonomusa (6 – 8 bugs and larvae on 1 sq.m), tolstonozhka (20 – 25 imagos on 100 waves a net), plant louses, a scoop, geometrids. Apply for this purpose bazudin, century of (2,0 – 3,0 l/hectares), volaton, to. e. (0,8 – 1,5 l/hectares), decis, to. e. (0,5 – 1,0 l/hectares), diazinon, to. e. (1,0 l/hectares), zolon, to. e. (1,4 – 2,8 l/hectares), karate, to. e. (0,15 l/hectares), kinmiks, to. e. (0,3 – 0,4 l/hectares) or shtefesin, 2,5 % to. e. (0,5 – 1,0 l/hectares).
Sunflower crops in formation a koryozinok – flowerings with a view of protection against a plant louse and bugs process fufanony (0,6 l/hectares), caterpillars of a luyogovy butterfly – detsisy, to. e. (0,25 l/hectares) or shte-fesiny, to. e. (0,25 l/hectares).
At identification on baskets white or gray gnili more than 3 % carry out spraying derozaly, to. page (1,5 l/hectares) or rovraly flo, to. page (3,0 l/hectares). Against fomopsisa good results gives dvukhyorazovy spraying of crops (before flowering and at the end of it) a preparation kolfugo super, to century of page (2,0 l/hectares) or korbely, to. e. (0,8 l/hectares).
Under condition of mass emergence in crops kartofelya larvae of the Colorado beetle 1 and the 2nd pokoleyoniya, their number and settling of 10 % of plants by them crops spray 10 – 20 copy/bush one of preparatov: the actor, century of (0,06 – 0,08 kg/hectares), mospilan, genitive (0,020 – 0,025 kg/hectares), a konfidor maxi, century of (0,045 – 0,050 kg/hectares), the regent, to. e. (0,05 – 0,06 l/hectares).
Against fitoftoroza and alternarioza primenyayutodin from fungicidov: acrobat of MTs, z. the item (2 kg/hectares), tat-that, to. page (3 l/hectares), titan M-45, z. the item (1,2 – 1,6 kg/hectares), ridomil Gold, z. item (2,5 kg/hectares), tanos, century of (0,6 kg/hectares), kurzat R, z. the item (2,5 – 3,0 kg/hectares), antrakol, century of (1,5 kg/hectares). The first spraying of plants carry out at emergence of the first symptoms (spots), the following – in 7 – 10 days when using contact preparatov, in 10 – 14 days – at application of sistemyono-contact preparations. Norm of a consumption of liquid at land spraying – 200 – 400 l/hectares. In case of a clash of dates of the processings applied against the Colorado beetle and against diseases, osushhestvlyayut simultaneous spraying of crops by an insecticide and fungitsidy.
