【 摘 要 】

We proved that tank mixture (Task Extra 440 g ha -1+ Par Trend 0.2L ha -1+ Vympel 1000 g ha -1 ) had the maximum efficiency in corn protection against the weeds in the conditions of Northern Ukrainian Steppe. This mixture had high index of herbicide technical efficiency (96.6%) and contributed to a steady tendency to increase the plant height by 5-7 cm (2.1-2.8%), the leaf surface area by 5-6%, structure elements of the yield (cob length by 13.6 cm (5.1%), cob graininess by 18 pieces (3.9%), weight of 1000 grains by 29 g (9.1%) and grain yield by 0.33 t ha -1(5.3%) compared to control. The tank mixture of the herbicide Titus Extra with the plant growth regulator Vympel (Titus Extra 50 g ha -1+ Par Trend 0.2L ha -1+ Pennant 500g ha -1 ) has also positive effect and was slightly lower than Task Extra 440 g ha -1+ Par Trend 0.2L ha -1+ Vympel 1000 g ha -1 ) for the grain yield by 0.12 t ha -1(1.9%).
