The purpose of research - development and implementation of environmentally friendly models bio-economic integrated control weeds in seed cropping of perennial grasses, chickpeas and beans, will ensure reduction of wideness to 92-95% and increase of productivity to 48-56%. The study was conducted by conventional methods in herbology. Used have laboratory-field method - to determine the species composition and quantity of the main weeds; mathematical and statistical - to establish the reliability of mathematical data; settlement and comparative - to establish the yield and economic evaluation of measures protecting crops from weeds. It is established that the crops crowfoot second year of life in the application of herbicide mixtures pivot, 0.6 l/ha of targa super, 2.0 l/ha reduction of weeds was 91-94%, and saved the harvest reached 0,8- 1.0 kg/ha (77-81%). In white clover crops with mixed type of weed-infested high biological effectiveness of herbicide mixture had ahritoks, 0,7-1,0 l/ha, pivot,0.6 l/ha; bazahran, 2.0-2.5 l/ha, shogun, 1.0 l/ha. reduced the number of weeds in 90-93%, and the yield was saved 0,64-0,73 kg / ha (78-81%). The significant decrease in the yield of chickpea sowing seeds observed in the presence of crops 10 pcs./m2 weeds. The high herbicidal activity in crops of chickpeas found at preemergence application of: stomp, 4.0 l/ha, harness, 1,5-3.0 l/ha frontyer optima, 0.8-1.0 l/ha, and e-post herbicides: pulsar, 0.9 l/ha pivot 0.5-0.8 l/ha. Control of weeds was at 90-91 %, and saved harvest - 0,72-0,89 t/ha. Reemergence application of proponit,2,5 l/ha frontyer optima, 3.0 l/ha gezagard, 3.0 l/ha, stomp, 4.0 l/ha, artist, 2.0-2.5 kg/ha and e-post - hvardian tetra 3.5 l / ha pulsar 0,7-1,0 l / ha bazahran 2.0 l / ha in common bean crops provide the level of control of weeds within 90% and saved the harvest was 12-19%. Also selected range of chemical herbicides for weed cereal grasses. Scientific novelty is in the development of environmentally-friendly integrated control of weeds in crops lolium, wheatgrass comb, common bean, chickpea seed. Chemical weed control method used taking into account the specific composition of weeds and their harmfulness thresholds in crops for a particular culture. The methods use reduced consumption rates of herbicides. Scope: agricultural enterprises of different ownership.
