Plant protection measures in flax cultivation should provide sufficiently clean from weeds, healthy sowings, forming the crop of necessary quality level, corresponding to economic and ecological criteria of modern agrotechnologies. The work aims to find promising herbicidal and protectivestimulating agents for providing cleanness from weeds and the health of flax crops when treating them with new pesticides, contributing to increasing the yield and quality of flax products. According to the classical methodology of scientific agronomy, the main experiments were carried out in the fields of FSBSI Federal Scientific Centre for Bast Crop, Flax Research Institute in the Tver region. As a result of experiments in 2018-2020, the herbicide Shanti and its mixture with Shanstrel 300 showed relatively high biological efficacy in protecting flax against dicotyledonous weeds. Furthermore, the addition of graminicides Haloshans or Cletoshans, growth regulator Artafit or fungicide Zimoshans to anti-wort herbicides did not reduce the effectiveness of the drug mixtures on dicotyledonous weeds and eliminated cereal weeds in crops. Additionally, Artafit and Zimoshans effectively protected flax from pasmo and other diseases, naturally increasing the yield of flax products. Its maximum values in the experiment were obtained in the variant of Artafit application together with herbicides. The use of Artafit had a positive effect on the quality of flax straw, increased it by 1-2 grades (from 2.00 to 2.50). |
