Holodryha O. Efficient application of targa super and emistym S in soybean fields in the conditions of the Right-Bank Forest Steppe Zone of Ukraine

Rational combination of targa super herbicides with emistym S growth regulator and their combined effect on weed infestation of soybean fields and weed varieties, physiologic-biochemical processes in soybean plants and soil, developing yield and improving soybean duality, power - producing and economic effect of their combined application were studied. It was found that application of the herbicides and growth regulator decreased weed infestation of soybean fields. It had an impact on physiologic-biochemical processes in soybean plants and soil, yield increase and grain quality improvement, power and economic evaluation of the combined application of preparations. In addition synergism of preparations effect at their use was found. The scientifically grounded, ecologically safe rates of preparations were defined, their production and biological efficiency in research and field experiment was as follows: targa super 1,5 litre/hectare, emistym S 5 ml/ hectare.
