Common types of biological pesticides for flowers
(Agricultural Wealth Network) Control of flower leaf-eating pests
1. Insect growth regulators. The diflubenzuron series of insecticides are new insect growth regulators, and their insecticidal mechanism is to inhibit the synthesis of chitin in the insect epidermis. Diflubenzuron-type products are mainly stomach poisons, but they can also penetrate the insect epidermis to take effect. This product has the advantages of good control effect, long residual activity, low control cost, resistance to rain washing, difficulty for pests to develop resistance, and safety to flower plants, humans, livestock and the environment.
2. Bacterial pesticide - Bt emulsion. Bt emulsion is a microbial pesticide of Bacillus thuringiensis, belonging to the Bacillus bacterial insecticide category. Its main insecticidal component is parasporal crystal. This pesticide has now become a major biological insecticide widely used in countries around the world. The pathogenic mechanism of Bt emulsion is that the Bt insecticidal toxin causes pathological changes in the pest's digestive tract and leads to death. After leaf-eating pests eat leaves carrying Bt emulsion, they become paralyzed, stop feeding, respond slowly, and develop diarrhea, after which black rings appear on the abdomen and gradually spread over the whole body, ultimately leading to death from poisoning. After death, the pests become black soft bodies, rot, hang upside down, or die on leaves and branches. Bt preparations have pathogenic and toxic effects on many Lepidoptera larvae and leafhoppers, such as fruit borers, yellow slugs, geometrid moths, etc., and are mainly used to control the larvae of Lepidoptera pests.
3. Botanical pesticides, mainly including the following four types.
1% nicotine matrine celastrus oil: a multi-component Chinese herbal botanical emulsifiable concentrate insecticide. It can also quickly kill insects prone to resistance, and has the characteristics of good degradation, no residual toxicity, safe use, no public hazard, and no pollution. It also has a growth-stimulating effect on flowers.
Baicao No. 1 (0.6% matrine lactone aqueous solution): made from various plants and Chinese herbal medicines such as Cynanchum komarovii and Sophora alopecuroides through crushing, dissolving, and adding adjuvants and penetrants. Its mechanism of action is mainly contact poisoning, with stomach poisoning as a supplement. It promotes flower growth and can be used to control various aphids and leaf-eating pests on flowers.
Baichongsha (1.2% nicotine matrine emulsifiable concentrate): belongs to botanical pesticides. Its active ingredients are nicotine and matrine, and it has stomach poisoning, contact poisoning and fumigant effects on insects. It has low toxicity to humans and livestock, causes no environmental pollution, and causes no phytotoxicity to flowers.
Shuguojing (0.5% toosendanin emulsifiable concentrate): belongs to botanical pesticides. This pesticide is efficient, safe, low-toxicity, and low-residue, and will not cause phytotoxicity to flowers. It also has stomach poisoning, contact poisoning and a certain antifeedant effect.
Control of flower piercing-sucking pests 1. Fungal pesticides, mainly aphid-killing fungus.
Aphid-killing fungus is a new fungal biological pesticide. Its main insecticidal component is an ester-soluble sterol compound. It has low toxicity, quickly knocks down aphids, and also kills spider mites, while not harming beneficial insects such as green lacewings and ladybugs. It has a growth-promoting effect on flowers.
2. Antibiotic series pesticides.
Abamectin (1.8%, 0.9%): Abamectin is also called Aifuding. Its active ingredient is avermectin, and it is currently widely used at home and abroad. It can effectively control many plant-feeding mites and other pests that are insensitive to commonly used pesticides or have developed resistance, such as red spider mites, leaf miners, slug moths, geometrids, tussock moths, psyllids and other leaf-eating and piercing-sucking flower pests. It has stomach poisoning and contact poisoning 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 easily decomposes when exposed to oxygen, light, etc., has no residue, and is beneficial to humans, livestock and flower plants.
Liuyangmycin (10% aqueous preparation): an acaricide and a new type of antibiotic agent.
Huaguangmycin (2.5% powder preparation): a new type of antibiotic acaricide. This pesticide does not pollute the environment, leaves no residue in air or soil, and has a protective effect on beneficial insects.
3. Botanical pesticides, mainly Huweiniao (0.5% veratramine alcohol), which is a botanical pesticide. It uses veratramine alcohol solution as the main raw material. It has the best effect on various aphids, especially aphids prone to resistance, and also has a certain effect on spider mites.
