Currently, the widely recognized and applied types at home and abroad include bacterial, fungal, insect hormone, entomopathogenic nematode, and insect virus types. Which ones are used?

Controlling piercing-sucking pests of flowers

First, fungal pesticides, mainly Aphid-killing fungus. Aphid-killing fungus is a fungal biological pesticide, and its main insecticidal component is an ester-soluble sterol compound. It has low toxicity, knocks down aphids quickly, and also kills spider mites, without harming beneficial insects such as green lacewings and ladybugs, and has the effect of promoting flower growth.

Second, avermectin-series pesticides, mainly the following 3 types. Abamectin: Abamectin is also called Aifuding, and its active ingredient is avermectin, which is currently widely used. It can effectively control many plant-feeding mites and other pests that are insensitive or resistant to commonly used pesticides, such as red spider mites, leaf miners, slug moths, inchworms, tussock moths, psyllids, and other leaf-feeding and piercing-sucking flower pests. It has stomach poison and contact-killing effects on mites and other pests. Compared with chemical pesticides, after using this pesticide, predatory and parasitic beneficial insects recover quickly, which is conducive to ecological balance. This pesticide decomposes easily when exposed to oxygen, light, and so on, has no residue, and is beneficial to humans, livestock, and flower plants. 10% Liuyangmycin aqueous solution: a miticide, a new type of agent. 2.5% Huaguangmycin powder: a new type of miticide, this pesticide does not pollute the environment, has no residue in air or soil, and protects beneficial insects.

Third, botanical pesticides, such as 0.5% veratridine alcohol, which is effective against various aphids, especially aphids prone to developing resistance, and also has a certain effect on spider mites.
