What are the uses of tebufenozide?

Tebufenozide has the characteristics of broad spectrum, low toxicity and low toxicity, and has stimulating activity to insect ecdysone receptor. The mechanism of action is that larvae (especially Lepidoptera) shed their skin when they should not molt after feeding, and the larvae die of dehydration and starvation due to incomplete molting. At the same time, it can control the basic functions of insect reproduction and has a strong effect of chemical sterilization. Tebufenozide has no irritation to eyes and skin, has no teratogenic, carcinogenic and mutagenic effects on higher animals, and is very safe for mammals, birds and natural enemies.

Tebufenozide is mainly used to control pests in citrus, cotton, ornamental crops, potatoes, soybeans, tobacco, fruit trees and vegetables, such as aphids, Cicadaceae, Lepidoptera, Liriomyza huidobrensis, Leaf mites, Thysanoptera, Root warts nematodes, Lepidoptera larvae such as pear heart borer, grape roll moth, beet armyworm and so on. This product is mainly used for 2-3 weeks. It has a special effect on Lepidoptera pests. High efficiency, 0.7 ~ 6g per mu (active matter). Used for fruit trees, vegetables, berries, nuts, rice, forest protection.

Because of its unique action mechanism and no cross-resistance with other insecticides, it has been widely used in the protection of crops such as rice, cotton, fruit trees, vegetables and forests to control various pests such as Lepidoptera, Coleoptera, Diptera and so on. at the same time, it is very safe for beneficial insects, mammals, environment and crops, so it is one of the ideal integrated pest control agents.

Insect hydrazide can be used to control pear heart borer, apple leaf roll moth, grape leaf roll moth, pine caterpillar, American white moth and so on.

Second, is tebufenozide toxic?

Acute oral LD50 rats and mice > 5000mg / kg; acute transcutaneous LD50 rats > 5000mg / kg; eye and skin irritation: very little; mutagenicity: negative; environmental toxicity: wild duck 8-day daily intake LC50 > 5000mg/kg, rainbow trout 96-hour LC50:5.7mg/L, water flea 48-hour EC503.8mg/L, bee 96-hour exposure LD50 > 234 μ g / bee, no effect on the growth of young bees. Beneficial arthropods: under laboratory conditions, tests on carnivorous ladybugs, carnivorous mites and some carnivorous wasps and spiders showed negative.

III. Usage of tebufenozide

Control jujube, apple, pear, peach and other fruit trees leaf rollers, heart-eating insects, all kinds of caterpillars, leaf moths, inchworm and other pests, with 20% suspending agent 1000-2000 times liquid spray.

To control resistant pests of vegetables, cotton, tobacco, grain and other crops, Helicoverpa armigera, Plutella xylostella, Pieris rapae, Plutella xylostella and other Lepidoptera pests were sprayed with 20% suspending agent 1000-2500 times.

IV. Matters needing attention in the use of tebufenozide

The effect of this drug on eggs is poor, and the spraying effect is good at the initial stage of larval occurrence. Tebufenozide is toxic to fish and aquatic vertebrates and highly toxic to silkworms. Do not pollute the water source when using drugs; it is strictly forbidden to use drugs in silkworm culture areas.
