Problems solved by technology

However, traditional control methods such as spraying pesticides often lead to serious social problems such as severe damage to biodiversity, increasingly serious environmental pollution, and food safety cannot be guaranteed.
At present, there is no product on the market that uses the superior natural enemy of the cotton aphid, Cotton aphid, to prevent and control aphids.

Embodiment Construction

[0009] The invention mainly uses 5% aspartic acid and 5% glutamic acid mixture as raw materials, adjusts the acidity and alkalinity of the slow-release agent by adding HCL and NAOH, and adds an appropriate amount of water to prepare the artificial honeydew sustained-release agent.

[0010] Add DCD (0.5MOL), water and 37% HCL (0.5MOL) into the container, stir to dissolve, slowly add an aqueous solution containing 5% aspartic acid and 5% glutamic acid dropwise within 20 minutes at 30°C , then stirred and reacted for 1 hour, then added NAOH solution to make the liquid slightly alkaline, crystallized overnight, filtered, washed with a little cold water, dried to obtain the product, and fully stirred to obtain artificial aphid honeydew sustained-release agent.

Abstract

The invention provides a preparation method of an artificial aphid honeydew sustained release agent. According to the preparation method, a mixed solution of 5% of aspartic acid and 5% of glutamic acid is taken as a raw material, HCl and NaOH are added for adjusting pH value of the artificial aphid honeydew sustained release agent, and the artificial aphid honeydew sustained release agent is obtained after adding of an appropriate amount of water. The artificial aphid honeydew sustained release agent is sprayed for luring natural enemies; the artificial aphid honeydew sustained release agent is sprayed before outbreak of aphid insect attack, so that the number of cotton aphid is controlled by luring and controlling natural enemy ladybird; and the artificial aphid honeydew sustained release agent is capable of realizing effective prevention on insects via biological control. One the one hand, time-lag effect caused by following effect of natural enemies on insects under natural conditions is avoided; and on the other hand, effective protection and utilization of the natural enemies are realized, and using of chemical pesticides and agricultural production loss are reduced.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a preparation method of artificial aphid honeydew slow-release agent. Background technique [0002] Cotton is one of the most important crops in the world, with high yield and low production cost. The cotton aphid is a kind of insect of Aphididae, which is a worldwide cotton pest. It occurs in every cotton area in China and is one of the main pests of cotton seedlings. Its stylet puncture and saliva secretion can cause chlorosis and necrosis of plant leaves and can also spread plant virus diseases. [0003] The honeydew secreted by the cotton aphid is weakly volatile, which helps its dominant natural enemy, the seven-spot ladybug, to search and prey on the cotton aphid. At present, studies have shown that the honeydew secreted by tea aphids has an attractive effect on the heterochromia ladybug. In the case of low pest population density, spraying sugar solution by artificially...
