Dressing as optimal protection of grain crops Cereals are the largest and most important group of agricultural crops, which occupy about 70% of the arable land in Russia. However, obtaining high and high-quality yields of these crops depends on the use of optimal plant protection systems from pests. And the first important step in this process is seed dressing. Recently, there has been a deterioration in the phytosanitary state of crops as a result of disturbed crop rotation, incorrect choice of predecessors, deterioration in the quality of soil cultivation and non-compliance with protection schemes. In addition, in recent decades, significant changes in climate have occurred, in combination with transformations in agrocenoses, have led to a significant reformatting of phytopathogenic and entomological complexes of grain crops. Today, significant damage to winter wheat and barley crops is caused by pathogens of helminthosporium and fusarium root rot, Alternaria, snow mold and spotting. Therefore, the preparation of seed should be given special attention. In this regard, the constant search for combinations of active substances that would reliably control the situation in grain crops at the beginning of the growing season is absolutely justified. The “Catalog of pesticides and agrochemicals permitted for use in the territory of the Russian Federation” presents a wide range of seed disinfectants for grain crops. Among them there are drugs with systemic or contact-systemic action, which contain one or more active substances. Disinfectants, It is to this group that the disinfectant Alpha-Treater, TCS, contains two active ingredients: 100 g / l of imazalil and 60 g / l of tebuconazole. Imazalil belongs to contact active substances. It is a protective fungicide that does not penetrate the seeds, inhibits the germination of spores or the growth of exogenous mycelium. The active substance - tetramethylthiuram disulfate - is translocated into pathogen cells, inhibits the activity of enzymes containing copper atoms or sulfhydryl groups. Preparations based on imazalil are used to treat seeds against root rot pathogens, mold, and other diseases, the pathogens of which are on the surface of the seeds. Tebuconazole is a representative of azoles - sterol biosynthesis inhibitors, which are responsible for the strength of cell membranes. Azoles do not suppress spore germination, but they inhibit further growth tube elongation, cell differentiation, and endogenous mycelium growth. Chemical stability provides a long period of protective action. Good solubility in water allows them to be translocated by the plant from the roots to the aerial parts. When treating seeds, tebuconazole effectively acts on smut fungi and seed molds. In order to determine the effect of the disinfectant Alfa-Protravitel, TCS on the level of residual infection of fungal etiology, energy and germination of winter wheat and spring barley seeds, laboratory experiments were carried out. Thus, as a result of laboratory experiments (FGBOU VPO RGAU-Moscow Agricultural Academy named after K.A.Timiryazev, Moscow), it was found that the treatment of winter wheat seeds and spring barley with the preparation Alfa-Protravitel, TCS with consumption rates of 0.3-0 , 4 l / t can significantly reduce the level of general infection of grain (83.3-89.4%). This makes it possible to protect seeds in the field at the early stages of plant growth and development while increasing yields by at least 10%. In addition, field studies in various soil manifestations have confirmed the high protective ability of the drug Alfa-Protravitel, TCS with consumption rates of 0, As a result of laboratory and a number of field experiments, it was found that the treatment of seeds of grain crops with the drug Alpha-Treater, TCS significantly increases the energy of germination, germination of seeds and enhances the growth of the root system. That is, it becomes the optimal drug that protects seedlings of cereals from a wide range of diseases and also has a powerful stimulating effect on the plant.
