Green method for controlling citrus aphids

Abstract

The invention belongs to the technical field of pest control, and specifically relates to a green method for controlling citrus aphids. According to the green method, a citrus foliar fertilizer is applied, and an insect repelling and trapping plant is planted. Specifically, the green method comprises following steps: obtaining a formula, a preparation method, an application method, and applicationfrequency of the citrus foliar fertilizer, picking an insect repelling and trapping plant, and planting the plant. The method mainly utilizes a plant to carry out biological control, the drug resistance of aphids is inhibited, the number and density of aphids are effectively controlled, the effect is long lasting, the using amount of conventional fertilizers and pesticides is largely reduced, atthe same time, the citrus quality is improved, and the economic benefits and ecological benefits are both increased.

Description

technical field [0001] The invention belongs to the technical field of pest control, and in particular relates to a green control method for citrus aphids. Background technique [0002] Citrus is a Rutaceae plant, which has a cultivation history of more than 4,000 years in my country. The output and area of ​​citrus in my country ranks first in the world. Citrus fruit is rich in nutrition, and more than 30 kinds of human health substances contained in it have been isolated, mainly including: flavonoids, monoterpenes, coumarins, carotenoids, propanols, acridones, glycerol glycolipids, etc. And the color and fragrance are both excellent, not only can be eaten fresh, but also can be processed into various products such as fruit juice, canned food, citrus tea, etc., and has high edible value and economic value. [0003] Aphids are one of the most important pests on citrus trees. They form clusters of adults and nymphs to directly suck the leaves and fruits of plants, resulting ...

AI Technical Summary

Problems solved by technology

[0003] Aphids are one of the most important pests on citrus trees. They form clusters of adults and nymphs to directly suck the leaves and fruits of plants, resulting in the loss of plant nutrients, stagnation or delay of tissue growth, and premature aging, resulting in poor fruit quality and low yield. Secondly, aphid saliva contains certain amino acids and plant growth hormones, which cause spots, shrinkage, galls, tumors, etc. on plant leaves, providing a favorable growth environment for aphids, while reducing the effective leaf area of ​​plants and reducing photosynthesis; Furthermore, when aphids suck and feed, they transmit various viruses, especially the citrus decay virus known as "fruit tree cancer", which is one of the most serious citrus diseases in the world. At the same time, aphids secrete honeydew, Breeding fungi, causing sooty disease on leaves and fruits, affecting plant respiration and photosynthesis, and honeydew is easy to attract ants, hindering or even repelling the approach of pollinating insects

Since the control of citrus aphids in production mainly relies on chemical agents, and tends to use agents with high insecticidal activity and a relatively single action site, coupled with the increase in dosage and high frequency of application in recent years, resulting in the death of a large number of natural enemies, the resistance of aphids is gradually increasing. improve
