ON THE EFFICIENCY OF USING TWO-COMPONENT HERBICIDES ON POTATOES IN THE FOREST-STEPPE ZONE OF THE CHECHEN REPUBLIC
Abstract and keywords
Abstract (English):
The objective of the study was to optimize the elements of potato cultivation technology based on the rational use of the biological potential of the crop, taking into account the agroclimatic conditions of the forest-steppe zone of the Chechen Republic. The type of weed infestation in the experiments was mixed: annual - 62.0%, perennial, respectively - 38.0%. The use of Quickstep, EC at a rate of 0.3 l / ha ensured 93.9% death and 94.8% reduction in weed weight. The use of Quickstep, EC at a rate of 0.3 l / ha ensured 100% death of weeds. Against the background of pre-planting treatment of tubers with the natural growth regulator Guma + 7 at a concentration of 0.01%, the potato yield in control 1 (without herbicides and weeding) was 22.00 t / ha. The greatest increase in yield was observed when using Quickstep, EC at a dose of 0.4 l/ha 12.80 t/ha, which is 58.2% compared to the control. Thus, in potato plantings in the fight against weeds in the forest-steppe zone of the Chechen Republic, the most effective is the use of the domestically produced herbicide Quickstep, EC at a dose of 0.4 l/ha in combination with pre-planting treatment of tubers with the natural growth regulator Humate+7 at a concentration of 0.01%.
