DEVELOPMENT OF AN EFFECTIVE METHOD OF PRE-SEED TREATMENT IN SEEDS OF SUGAR BEET

Ashimkhan Kanayev

Abstract

The most important part of any successful program of obtaining stable yields of agricultural crops is the development of effective plant protection products. The use of pesticides and chemical control methods has revolutionized agriculture. Chemical means of protection attracted attention by cheapness, variety of drugs, and most importantly, high efficiency The toxicity of some pesticides did not cause much concern, and only excessive saturation of the environment with pesticides sharply raised the question of limiting their use and the need to find alternative means of protecting plants. Thus, a new direction emerged - the development of microbiological methods of protecting plants against phytopathogens. The results of studies of pre-sowing treatment of sugar beet seeds, providing: improving the sowing qualities of seeds; stimulation of physiological and biochemical processes of growth and development of seedlings; reducing the consumption of seed material; increasing the resistance of seedlings to pathogenic microorganisms. For pre - sowing treatment of sugar beet seeds, water - soluble film-forming polymers were used: carboxymethylcellulose (CMC-2%), polyvinyl alcohol (PVA-3%) protectants Maxim (2.5%, 5%) and Skor (2.5%, 5%). The experiment sown hybrid Aksu-normal-sugary hybrid Kazsib-14 in 9 variants of etching. Analysis of the data shows that the highest yield have variants of Maxim etching, which exceed the options of processed Skor yield on average 4.3-5.8 t/ha. Studies have established that PVA 3%, Max 5%, Max 2.5%, CMC 1%, Skor 2.5%, 5% ensure the increase sugar content compared to the other options of encapsulation.
