Abstract

The invention relates to agriculture and can be used for pre-sowing seed treatment of leguminous crops. The purpose of the invention is to increase the yield of plants, increase their resistance to diseases and reduce the consumption of tetramethylthiuram disulfide. The goal is achieved by the fact that before sowing the seeds are treated with a mixture containing 30% fluid film-forming paste tetramethylthiuramdisulfide and 3% phytobacteriomycin in the ratio (May.%) 17-65 and 35-83, respectively, The mixture has 100% adhering to the surface of the seeds, does not crumble and does not dust. The proposed method increases the yield of plants, reduces the incidence of their diseases. 2 tab.

Description

The invention relates to agriculture and can be used for pre-sowing seed treatment of leguminous crops.

The purpose of the invention is to increase the yield of plants, increase their resistance to diseases and reduce the consumption of tetramethylthiuramdisulfide.

Example. Two weeks before sowing, pea seeds are treated with a mixture containing 30% fluid film-forming paste tetramethyluramdisulfide (TMTD) and 3% phytobacteriomycin in the ratio (May.%) 17-65 and 35-83, respectively. The mixture is prepared in a treater bottle, adding a certain amount of room temperature water, stirred and left to stand for 10-15 minutes to swell the glue, after which the working solution is ready for use. TMTD consumption is 6 L per 1 ton of seed or 1.8 L for the active ingredient.

For comparison, seeds treated with either one dressing agent or one phytobacteriomycin were used. as well as the prototype method. The control was unpicked seeds.

The effectiveness of the proposed method of seed treatment was evaluated by the yield of plants and their resistance to disease. The results are presented in table. 1 and 2.

The development of pea diseases, depending on the method of presowing treatment of seeds, is shown in Table. 1. Pea productivity depending on the method of seed treatment is shown in table. 2.

As can be seen from the presented results, the treatment of seeds with the proposed method in comparison with other treatment methods increases the yield of plants and reduces the incidence of their diseases. In addition, there was an increase in field germination of seeds by 13.7% compared with

control and increase the density of one hundred plants by 18-20 pcs / m2. The number of seedlings of peas affected by the pathogens of root rot and ascochitosis was 4.1 and 2.2 times less, respectively. In all phases of plant development, an increase in peroxidase activity by 3-8 times, poly-phenol oxidase, 3-4 times, the content of ascorbic acid was noted.

The use of WfDL in the form of a 3% flowing paste makes it possible to reduce the consumption of the preparation for the active substance by 1.6–2.0 times as compared with TMTD in the form of an 80% free-flowing powder. At the same time, the adherence of the applied preparation to the surface of the seeds is 100%, and no flaking and decay is observed.
