Complex polymer preparations for the protection of seeds of grain crops of agricultural plants

Abstract

Pre-sowing treatment of seeds of cultivated plants with agrochemicals can significantly reduce crop losses. A promising technology for increasing the yield of spring crops in arid zones characterized by moisture deficiency in the summer is winter sowing. However, this method carries the risk of large losses as a result of premature germination of grain in the event of prolonged positive temperatures in the fall or severe thaws. Special grain processing chemicals can prevent such losses. Complex polymer preparations have been developed to protect grain seeds from premature germination and damage by phytopathogens. It has been shown that compositions based on polyvinyl acetate dispersions and polyacrylamide most effectively prevent premature germination of barley grains. At the same time, treatment with a copolymer of acrylamide and acrylate significantly reduced plant germination. It has been shown that when barley grains are treated with compositions based on polysaccharides with a fungicidal preparation, fungal infection is completely absent, and there is no significant inhibition of seed germination. This composition for treatment against fungal spoilage of grain and seedlings seems promising for practical use.
