The technology of receiving a quality crop of a winter and summer rape is given in article. Chemical preparations are listed and terms and doses of their application are specified.
The best predecessors for a winter rape are grain grains, leguminous, early potatoes, long-term and annual herbs. A rape – one of the best cultures for busy steam.
At emergence of weeds before crops of a winter rape them destroy preseeding cultivation. Thereof the need for application of herbicides decreases and population of fields a winter sovka decreases.
One of the most important elements of technology of receiving a quality crop is the protravlivaniye of seeds before crops. Processing of seeds by suspension of a preparation of Vitavaks 200, item page, (10 l of water on 1 ton) or incrustation (10 l of 0,2 % of NaKMC solution on 1 ton) apply 2-3 kg/t against alternarioza, a mold, peronosporoza, fomoza, white and gray decay. At application of the specified preparation it is forbidden to use a rape on a forage an animal and for production of oil for the food purposes. Rovral FLO, k.s. 8 l/t apply against a plesneveniye, alternarioza, gnily, fomoza by processing of seeds before crops (2l waters on ton), Maxim XL 035 FS, since page, 5 l/t against a plesneveniye, alternarioza, peronosporoza, fomoza, a black leg, by a protravlivaniye of seeds preparation suspension (5l waters/t).
To pest control of shoots before crops of seeds apply processing by preparations Space 250, since page, 8l/t; against krestotsvetny flea beetles and a cabbage plant louse use a protravlivaniye a preparation Chinuk, 20 % since page, 20 l/t. To fight only with krestotsvetny flea beetles apply a protravlivaniye Furadan’s preparation of 35 ST, (15l/t) or Hinufur, century of page (18 l/t). Preseeding processing of seeds of a summer rape against krestotsvetny flea beetles is carried out by a preparation Kruizer of 350 FS, (4 l/t).
At the timely crops, amicable shoots and optimum density of standing of plants use of herbicides is inexpedient, as the rape is the strong competitor in fight for light, moisture and food elements. Herbicides apply at bespluzhny processing of the soil, late shoots and under other adverse conditions. Bring them under preseeding cultivation. If necessary herbicides can be applied after emergence of shoots of a rape (in a phase of the second leaf). The last processing carry out at formation at a rape 3-4 leaves.
In the spring vegetiruyushchy weeds spray Raundap (2-5 l/hectares), in 2-3 weeks prior to crops of a summer rape. Before carrying out spraying exclude all machining of the soil, except early-spring closing of moisture.
At identification on shoots of a winter and summer rape of krestotsvetny flea beetles (3 and more individuals/sq.m or one prick in cotyledons for 30 % of plants) Alfagard, Sumi-alfa, Detsis Forte apply. In a phase of 2-4 leaves against a rape pililshchik
(2nd caterpillar/plant), rape listoeda (3 individuals/sq.m), cabbage white butterfly
(2 individuals/sq.m) crops process insecticides according to regulations of their application.
At emergence of signs fomoza and peronosporoza crops process preparations the Forcing + Ridomil Gold MTs or others resolved fungicidami.
In a phase of 4-6 leaves and prior to the beginning of a butonizatsiya against listoeda, a pililshchik and bugs apply Fyyuri (0,1 l/hectares), Bliskavka (0,150-0,165 l/hectares), etc.
Against larvae of the first generation of the cabbage white butterfly, pililshchik, at the end of a butonizatsiya and no later than in 20 days prior to cleaning, against a cabbage plant louse and rape cvetoeda (5-6 individuals/sq.m) apply Detsis Forte (0,06-0,07 l/hectares), Fyyuri (0,1 l/hectares), to Bliskavka (0,150-0,165 l/hectares) and other recommended insecticides.
At application of such preparations, as Detsis, 2,5 % k.e., Zolon, Karate, Fastak, Shtefesin is forbidden rape use on a forage to animals and for production of rape oil for the food industry.
Against a meadow moth during a mass yaytsekladka let out trixogrammu.
In vegetation against cabbage scoops can be used trixogrammu in 2-3 terms with an interval of 5-7 days. The first time at the beginning of a laying of eggs, in number of 20 thousand pieces/hectares, the subsequent – at the rate of 1 female on 20 eggs of the wrecker.
