Mint-copper false smut preventing-treating agent and preparation method thereof

Abstract

The invention relates to a mint-copper false smut preventing-treating agent and a preparation method thereof. The mint-copper false smut preventing-treating agent comprises the following constituents by weight: 5kg of mint leaf, 5kg of dandelion leaf, 1000kg of rice husk, 1kg of nano-complexed monovalent copper, 500g of monacus purpureus, 200g of geotrichum candidum, 100g of bacillus aceticusm and 200g of streptomyces griseus. In the late growth stage of rice, false smut can cause sterility of spikelet, grains are reduced, the development of the grains is influenced, and the grains have toxicities harmful to human and livestock. According to the mint-copper false smut preventing-treating agent, by virtue of the resistance of pathogen of the false smut to copper, the growth of pathogenic bacteria of the false smut is restrained under the actions of multiple antibacterial elements in mint, dandelion and rice husk which are extracted by virtue of fermentation; the utilized raw materials are non-toxic and nuisanceless vegetal materials having oxidase and other nutrients beneficial for the growth of rice, so that the development and ear-setting capacities and the stress resistance of the rice are improved.

Description

technical field [0001] The invention relates to a peppermint copper rice smut control agent and a preparation method thereof, belonging to the technical field of plant disease and insect pest control. [0002] Background technique [0003] Rice false smut can cause sterility of rice spikelets, reduce grain weight, and affect the development of grains. The pathogenic bacteria of rice false smut not only endangers the harvest of rice, but also contains toxins to humans and animals. In areas where rice is the staple food, edible Rice with rice smut is a potential threat to human health. Experiments have shown that if pigs are fed with rice bran with rice smut, sows will have dystocia, stillbirth and deformed fetuses. Most of the prevention and control methods of the disease are based on the principle of antibiotics. Although the effect is good, it is easy to cause environmental pollution, reduce the vitality of the soil, and have an impact on the health of humans and animals. ...
