Problems solved by technology

At present, the disease is mainly controlled by chemical control and planting resistant varieties, but due to the genetic complexity and pathogenicity diversity of the pathogen races, new resistant varieties often lose their resistance after several years of promotion; chemical Due to the long-term use of pesticides, it is easy to produce drug resistance, and the control effect becomes poor, which increases the amount of pesticides year by year, pollutes the environment, and the increase of pesticide residues has adverse effects on human health.

Abstract

The invention discloses a resistance inducer for inducing rice to resist rice blast. The resistance inducer for inducing rice to resist rice blast comprises the following components: sodium nitroprusside, salicylic acid, chitosan oligosaccharide and potassium iodide. 100 ml of a resistance inducer comprises the following components in parts by weight: 0.75 to 1.5 g of sodium nitroprusside with the mass concentration of 99.5 percent, 3 to 7.5 g of salicylic acid with the mass concentration of 99.5 percent, 1.5 to 3 g of chitosan oligosaccharide with the mass concentration of 95 percent and 1.0 to 1.5 g of potassium iodide with the mass concentration of 99.9 percent, wherein the salicylic acid is dissolved with ethanol and other components are dissolved with water. The resistance inducer is sprayed on rice leaves at the initial heading stage of the rice, the activities of the active substances and enzyme in the rice are activated after the resistance inducer is absorbed by the leaves, infection of magnaporthe oryzae is resisted, disease speckle expansion is inhibited, and occurrence and harm of the rice blast are prevented and reduced.

Description

technical field [0001] The invention relates to an inducer, in particular to an inducer for inducing rice blast resistance, inducing rice resistance to blast fungus infection, and preventing and reducing the occurrence of rice blast. Background technique [0002] Rice is the most important food crop in China, and rice is the staple food of more than 65% of the population in China. At the same time, China is also the country with the largest rice production and rice consumption in the world, so rice production plays an important role in ensuring China's food security and stabilizing the world's rice market. Rice blast (Rice Blast) is one of the most serious rice diseases caused by Magnaporthe oryzae. It is widely distributed in various rice regions in the world. It occurs to varying degrees in the northern and southern rice regions of China every year, and the damage area and degree of damage are relatively large. large, which seriously hinders the high and stable yield of r...
