Problems solved by technology

The sugar content of sweet corn kernels is about 10 times higher than that of ordinary corn, and because of this, it is very easy to cause corn borers, scarabs, aphids and other pests. If not properly controlled, it will not only reduce the quality, but also have a huge impact on the yield , seriously endangering economic benefits
The current methods of preventing and controlling sweet corn pests and diseases mainly include the use of chemical pesticides and inoculation of Trichogramma eggs. Among them, the use of chemical pesticides is easy to produce pesticide residues, which will seriously damage human organs after people eat them. Long-term use will cause genetic mutations in pests and produce resistance, and will also reduce the yield of corn, and the method of inoculating Trichogramma egg mass only has a certain effect on corn borer. The inoculation is greatly affected by the weather, and often one inoculation is unsuccessful, which will destroy the ecological balance in the long run

Abstract

The invention relates to the field of planting of agricultural products and especially relates to a method for preventing and treating plant diseases and insect pests of sweet corn. According to the method provided by the invention, a formula drug is sprayed onto the sweet corn plant in the small-horn period of the sweet corn. The formula drug is prepared from the following raw materials in parts by weight: common nepenthes extracting solution, dionaea muscipula extracting solution, cinnamomun camphcra extracting solution, caulis spatholobi extracting solution, nettle extracting solution and cocklebur fruit extracting solution. The formula drug has an obvious effect in preventing and treating the corn pests, such as, european corn borer, scarab and aphis, is capable of reducing the occurrence rate of the plant diseases and insect pests of the sweet corn to 0.2%, is free from chemical pollution and is capable of preventing the plant from resistance to drugs.

Description

technical field [0001] The invention relates to the field of planting agricultural products, in particular to a method for preventing and controlling sweet corn pests and diseases. Background technique [0002] Sweet corn is one of the main vegetables in developed countries such as Europe, America, Korea and Japan. Because of its rich nutrition, sweetness, freshness, crispness and tenderness, it is favored by consumers from all walks of life. Sweet corn in production can be divided into three categories: normal corn, super sweet corn and enhanced sweet corn. Super sweet corn is widely planted due to its high sugar content and long suitable harvesting period. The sweet corn plants are shorter, with stronger tillering ability, and there are flag leaves on the bract leaves of the ears. The grains are light yellow or white, the embryos are large, and the seeds are soft and tender at the milk-maturity stage, rich in water-soluble polysaccharides, vitamin A, vitamin C, fat and p...
