Glucose oligosaccharide acid derivative bioactive factor composition

Abstract

The invention relates to a glucose oligosaccharide acid derivative bioactive factor composition for preventing and treating rice blast. The glucose oligosaccharide acid derivative bioactive factor composition is prepared from potassium glucose oligosaccharide acid, iodine glucose oligosaccharide acid, polypeptide and an additive which are combined according to the proportion of (35.0-50.0%): (10.0-15.0%): (39.9-49.5%): (0.1-0.5%), and all the components are weighted according to the proportion and sufficiently mixed and packaged to form powder, particles or tablets. The composition has favorable preventing and treating effects on rice blast, the application amount of the composition is 5-10g / mu, and the composition is sprayed 2-3 times at the initial stage of rice blast and is simple and convenient to apply, capable of saving labor time, high in disease prevention effect up to 70% and better in promotion effect on agricultural production.

Description

technical field [0001] The invention relates to the technical field of agriculture, in particular to a bioactive factor composition of oligomeric acid derivatives used in agriculture. Background technique [0002] For grass rice, due to the widespread occurrence of rice blast, it usually results in a 30-50% reduction in yield. Due to the long-term use of chemical pesticides, the resistance of pathogens has increased year by year. The use of biological source preparations can induce disease resistance through plant theory. And the principle of irreversible denaturation of pathogen protein is an innovative method to prevent and control rice blast. Oligomeric active substances include oligosaccharins, oligomeric acids and peptides, etc. There have been many literature reports that have non-specific induction of disease resistance to plants. The combination of iodine and protein can cause irreversible enzyme inactivation of the pathogen, and there is no related report at home an...
