Method for soaking seed in Chinese herbal medicine for prevention and cure of diseases and insect pests of rice, maize and vegetable

Abstract

The invention discloses a method for soaking seed in Chinese herbal medicine for prevention of diseases and insect pests of rice. The method comprises the following steps of: cooking the Chinese herbal medicine including 10 parts of david poplar bark by weight, 10 parts of walnut bark by weight and 10 parts of radix scutellariae by weight, and 70 parts of water by weight for 2 hours slowly, filtering the Chinese herbal medicine and removing the slag to obtain the mixed Chinese herbal liquid medicine; secondly, soaking 1 kg of rice seeds by 40 to 60 g of the Chinese herballiquid medicine, adding water to dilute the Chinese herbal liquid medicine and making the water submerge the seeds rightly; thirdly, soaking the seeds for 3 to 5 days, sprouting and raising the rice seedlings or directly sowing the seeds. The liquid medicine of the invention can prevent various diseases and insect pests and reduce the pollution of the chemical pesticide to the maximum extent, so that no pesticide remains in the grain and the human health is safeguarded; meanwhile, the production cost of the food crop is reduced greatly, the labor intensity, the time and the cost of purchasing pesticides for preventing diseases and insect pests are saved in the production process of the grains, and a new approach is provided for preventing the agricultural diseases and insect pests.

Description

technical field [0001] The invention relates to the technical field of botanical pesticides for preventing and controlling crop diseases and insect pests, in particular to a Chinese herbal medicine seed soaking method for preventing and controlling rice, corn and vegetable diseases and insect pests. Background technique [0002] In the existing technologies for preventing and controlling crop diseases and insect pests, the main technical solutions used include chemical pesticide control, biological and biological pesticide control, physical control, etc., but chemical pesticide control is generally used. Insecticides, fungicides, insecticides are divided into contact killers, stomach poisons, systemic agents, etc., fungicides are divided into various fungicides according to different mechanisms of killing bacteria or fungi, so different pests and diseases The types of chemical pesticides used also vary by species. The biggest defect of chemical pesticides to prevent and con...

Problems solved by technology

The biggest defect of chemical pesticides to prevent and control diseases and insect pests is the amount of pesticide residues. Although many existing pesticide varieties have the characteristics of high efficiency and low toxicity, which are relatively safe for humans and animals, there are still a large part of pesticides with long residual time and poor chemical properties. Stable, while killing pests and diseases, there are a large number of residues in crops, and the amount of residues increases with the increase of pesticide application, which greatly exceeds the safety limit. Chemical pollution is becoming more and more serious, and the environment and food that people depend on are increasingly polluted by chemical pesticides. Food safety has become a topic of common concern to human beings. How to fundamentally eliminate chemical pesticide pollution from the source , is the dream wish of scientific and technological workers. After years of exploration and research and a large number of field experiments, a pure Chinese herbal medicine has been found. It not only has a broad-spectrum insecticidal effect, but also has a broad-spectrum sterilization effect. , why there is such a miraculous effect, its mechanism of action is still unclear, and further in-depth research by experts is needed to uncover unknown secrets. According to the test results, after soaking rice seeds in the pure Chinese herbal medicine formulation provided by the invention for field experiments, the sowing No chemical pesticides are applied until harvest, and it has a good control effect on rice blast, especially the panicle neck blast, sheath blight, stem borer, and rice planthopper, which are seriously harmful in the local area. Compared with the same field or adjacent fields, Contrast field with 100 grams of 50% carbendazim, 5 million units of Jinggangmycin mixed with 45 kilograms of water to spray against rice blast and sheath blight, and 2 kilograms of 3.6% dimehypo to prevent stem borer; 10% 15 grams of Dagongchen, 5 million units of Jinggangmycin and 40 kilograms of water are sprayed to control rice planthopper and sheath blight
