EFFICIENCY OF HERBICIDES AND THEIR TANK MIXTURES IN WINTERWHEAT CROPS
We have studied the influence of herbicides and their tank mixtures with Esterone, CE on the weeding of crops and the yield of soft winter wheat of the Nemchinovskaya 17 variety on the experimental fields of the Fitz "Nemchinovka". Eight variants of spraying with herbicides and their tank mixtures are considered in relation to control without treatment in order to identify the most effective use of herbicides. The effectiveness of anti-weed herbicides was evaluated by reducing the number of weeds, increasing productivity, optimal financial costs for processing crops and the maximum positive financial result from spraying. Meteorological conditions during the experiment were close to the average long-term values. Herbicide treatment was performed once, during the tillering phase. The consumption of the working solution for spraying crops is 300 l / ha. The most effective is the introduction of a tank mixture of Eraser Extra, CE + Esteron, CE in the amount ofl / ha and 0.6 l / ha, respectively. In this variant, the number of cereals for control decreased by 95.7%, the highest increase in yield was noted to 6.10 t / ha, the highest financial costs for spraying were determined at 1887.12 rubles per 1 ha, but they are optimal relative to the value of the financial result obtained. This option provided the maximum positive financial result of 23612.88 rubles per 1 ha. We also conducted an economic analysis of spraying, which confirmed the highest efficiency of the tank mixture of Eraser Extra, CE + Esteron, CE in comparison with other treatment options and control. The analysis of indicators of the intensity of resource use during the spraying of crops with herbicides and their tank mixtures also confirmed the greatest effectiveness of the tank mixture Eraser Extra, CE + Esteron, CE.
