Foliar spraying agent for controlling corn diseases and insect pests and production method thereof

Abstract

A foliar spraying agent comprises the following components in percentage by weight: 0.2%-0.5% of ethephon, 5%-10% of jasmine flower residue water extract, 3%-5% of eucalyptus leaf water extract, 1%-3%of baeckea frutescens water extract and the balance of water. The production process comprises the following steps: (1) adding the ethephon into the water, and uniformly stirring to obtain an ethephon solution; (2) adding the jasmine flower residue water extract, the eucalyptus leaf water extract and the baeckea frutescens water extract into the ethephon solution, and uniformly stirring; and (3)filling the mixed solution obtained in the previous step into a dark container, and sealing to obtain the product. The foliar spraying agent is efficient and safe in pest control.

Description

technical field [0001] The invention relates to the technical field of preparations for preventing and controlling diseases and insect pests, in particular to a foliar spraying agent for preventing and controlling corn diseases and insect pests and a production method thereof. Background technique [0002] With the continuous improvement of people's living standards, people's dietary structure is gradually developing towards green and pollution-free coarse grains. At present, people regard the intake and possession of coarse grains as the standard to measure whether the dietary structure is healthy. Corn is a popular coarse grain product in people's daily life, especially sweet corn, because sweet corn can be used as a vegetable and a fruit. [0003] sweet corn( Sweet corn ) is a variety of corn, also known as vegetable corn, Poaceae, and the genus Maize. Sweet corn is one of the main vegetables in developed countries such as Europe, America, Korea and Japan. It is a type...

AI Technical Summary

Problems solved by technology

The sugar content of sweet corn kernels is higher than that of ordinary corn, and for this reason, it is very easy to cause pests such as corn borers, scarabs, aphids, etc. If the control is not done properly, it will not only reduce the quality, but also have a huge impact on the yield, seriously endangering the economy income

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
