The invention relates to the field of agricultural production, in particular to methods for protecting cereal crops from weeds and pests and nitrogen fertilizer application.

Intensive technology of cultivation of grain crops provide sequential, according to the stages of growth and development of plants, the use of pesticides and fertilizers, from 7 to 13 treatment plants during the vegetation period. A number of these technological operations can be reduced due to the replacement of 2-3 treatments one, because the deadline for applying pesticides, fertilizers and biologically active substances often overlap and can be used as mixtures.

Known methods of processing of grain crops herbicide-herbicide, herbicide-fungicidal (EN 2306703, EN 2116027, EN 2084151, EN 2106782), protecting fungicide (EN 2059367 C1) mixtures, based on thresholds of harmfulness of harmful objects, short-term forecasts and alarm of their occurrence, distribution and development with the aim of reducing the number of processing plants and increase their biological effectiveness, expanding the range of their actions and prevent resistance.

Find use and fertilizer-pesticide (EN 2059367) mixture, which along with the pesticides are soluble solid and liquid fertilizers to enhance the effect of pesticide is.

The application is used as a prototype mixtures provide a reduction of application rates of pesticides by 10-30% without reducing the biological activity, expansion of the scope of destruction of harmful objects, reducing costs by consolidating technological operations for cultivation of crops.

It should be noted that the List of pesticides and agrochemicals permitted for use in agriculture of the Russian Federation"which is annually updated with new high-performance, differing in chemical composition of pesticides, are excluded ineffective drugs with low biological activity and economic efficiency.

In recent years to control weeds, including those with problematic weeds in cereal crops widely used manufactured Kirovo-Chepetsk company herbicide - Cowboy-super - odnogolosy solution diethylethanolamine salts dicamba and chlorsulfuron. Introduction in its composition instead of water ethoxylate increased the speed of penetration of the active ingredients of the herbicide in plants weeds, i.e. herbicide activity of the drug in comparison with the previously produced by the Cowboy (RF patent No. 2040179).

For foliar fertilizing of crops in Rossi (1986) widely used liquid nitrogen fertilizer (UAN) solution of urea and ammonium nitrate (TU-113-0-27-52-83) (Applying a mixture of solutions of urea and ammonium nitrate in agriculture. - M: VO "Agropromizdat", 1988).

In this context, the technical task of the invention is to develop a new composition of fertilizer-pesticide mixtures possessing higher biological activity compared to the separate introduction of original components (fertilizers and pesticides), which reduces the rate of herbicide pollution. Farming through the application of nitrogen fertilizers and pesticides for crops in the form of mixtures is the coincidence of the timing of their introduction [Integrated fertilizer application in adaptive-landscape farming in the Nonchernozem zone of the European part of Russia (a practical guide). - M.: RAAS, VNIIA, 2005, - 160 C.].

The technical result of the present invention is to improve the effectiveness of the herbicide, the reduction in rates made by 25% of the minimum recommended, the reduction of 60% of the operating costs and the cost of labour in the cultivation of crops due to combination of technological operations foliar cortex nitrogen and applying pesticides.

This object is achieved in that the fertilizer-pesticide mixture containing liquid nitrogen fertilizer (UAN-32) and water, according to the invention further includes cowboy and super Kinex in the following ratio, wt.%: (UAN-32) - 30,0-40,0, combo the super - 0,11 0,20..., Kinex - 0,2...0,5, water - the rest is up to 100.

Technology of preparation of fertilizer-pesticide mixtures to make on 10 hectares of land (rate of flow of the working solution of 200 l/ha).

Example 1.

In the tank of the sprayer (2000 l) pour 1/3 of the volume of water, add 721,2 l KAS density of 1.3 g/cm3mix , pour 1.1 l cowboy super, 2 liter kenexa and water to fill.

Example 2.

In the tank of the sprayer (2000 l) pour 1/3 of the volume of water, add UAN-32 in number 721,2 l density of 1.3 g/cm3mix, pour 1.5 liters of cowboy super, 2 liter kenexa and water to fill.

Field experiments on the evaluation of biological and agronomic efficiency of fertilizer-pesticide mixtures held in LLC ConAgra" Klinsky district, Moscow area, in accordance with applicable regulations.

In the experiment compared the effect made in the phase of tillering of winter wheat the two mixtures, wt.%:

Fertilizer-pesticide mixture No. 1. (UAN-32) - 30,0 + cowboy super - 0,15 + cinemix - 0,20 + water - the rest is up to 100

Fertilizer-pesticide mixture No. 2. (UAN-32) - 30,0 + cowboy super - 0,11 + cinemix - 0,20 + water - the rest is up to 100

The results of field experiments showed that herbicide activity cowboy super in the studied mixtures are practically equivalent, i.e. the estimated mixture No. 2 allows to achieve postavlennuyu: to reduce the rate of cowboy super 25% of the minimum recommended due to the synergistic effect of pesticides and liquid nitrogen fertilizer, to improve the environmental safety of protective actions.
