Methods of application of the herbicides Tifi and Miura on oil flax

One of the reasons of incomplete yield of oil flax is high weeds prevalence in crop sowings and flax low competitive ability. So the purpose of this work was to study influence of methods of application of the modern herbicides Tifi and Miura used after flax seedlings appearance on weeds, productivity and yield quality of oil flax varieties bred in V.S. Pustovoit All-Russian Research Institute of Oil Crops (VNIIMK). The researches were conducted in a zone of unstable moistening on leached black soil (fields of VNIIMK, Krasnodar) - a variety FLIZ, and in a zone of insufficient moistening on typical black soil (Donskoy branch of VNIIMK, Oporny settl., Azov district, Rostov region) - a variety Raduga in 2018-2019. As a result we determined a high biological efficiency of the herbicides Tifi, WDG (0.025 kg per ha) and Miura, EC (1.2 l per ha) applied as tank mixture and separately in the zone of unstable moistening. In the zone of insufficient moistening the high biological efficiency was determined when applied Tifi, WDG (0...
