Weeds biological control technique

Abstract

Abstract The article discusses the results of a study on an environmentally friendly and safe technique aimed at reducing weeds on experimental agricultural lands. The technique consists in sowing a crop with high allelopathic properties: in the steam field, the winter false flax was sown in a mixture with annual clover shabdar in a ratio of 2:1, and in the phase of flowering the above-ground mass of both crops was mown and ploughed as a siderat. In another experiment, amaranth, which has high competitiveness, was sown in rows on corn sown in broad rows. A few days before sowing corn stimulated the growth of weeds with mineral fertilizers ammonium nitrate. After the appearance of weeds, a mixture of a half dose of the herbicide and Nikfan biological product was introduced. Upon reaching the developmental phase of corn of 5-6 leaves, amaranth in the aisles was ploughed as a siderat. Used in crop rotation crops, winter false flax, panicled amaranth, have a high allelopathic feature, reducing the number of weeds. As a result of the studies revealed a significant reduction in weeds. This technology of weed control significantly reduces the cost of weed control and creates favourable conditions for obtaining quality products.
