Effective protection of seedlings of large-fruited confectionery sunflower from pests
In the experimental fields of VNIIMK, tests were carried out methods for the protection of shoots of a large$scale confectionery sunflower from the soil pests. As an additional alternative method of protection, granules of Grizzly preparation were put into the soil 2 weeks before sowing culture. The introduction of this preparation against wires, a sandy paper and steppe cricket showed a high biological effect of 90-97 %. Inlaid of sunflower seeds with a Kruiser, CS, 10 l/t, and then putting into the soil the granules of Grizzly, G, 15 kg/ha increased the effectiveness of protection against a set of pests of shoots up to 100 %. For three years of testing, the high economic efficiency of these techniques was confirmed, and the amount of preserved harvest varied by years from 0,21 to 0,34 t/ha.
