Description

Insecticidal composition containing dicyclaniliprole and cyantraniliprole

Technical Field

The invention relates to an agricultural insecticide, the main effective components of which comprise dicyclopropyl tetramat and cyantraniliprole insecticide.

Technical Field

The dicyclopropyl caterpillar is a novel insecticide developed by basf for preventing and treating piercing-sucking mouthpart pests, has a unique action mode, and can effectively prevent and treat piercing-sucking mouthpart pests such as aphids, whiteflies, some psyllids and the like. The mechanism of action of the diproprionate is different from that of the conventional insecticide, and the diproprionate acts by interfering the regulation of the transient receptor channel complex of the vanillic acid of the insect, so that the feeding and other behaviors of the insect are interfered, and finally the insect is starved and killed.

Although the dicyclopropionate can stop feeding within hours after application, the knockdown effect is slow. The product has long lasting period, and the lasting effect on aphids can last for 21 days. The dicyclopropyl is effective on both imagoes and larvae, but the drug is recommended to be applied in the larval stage, so that the control effect is better. The dicyclopropyl tetramat can be used for economic crops, field crops, ornamental plants and the like, and can effectively prevent and control piercing-sucking and sucking mouthparts pests, such as aphids, whiteflies, psyllids, scale insects, mealybugs, leafhoppers and the like. The fertilizer can be used for treating leaf surfaces, seeds or soil.

The propiconazole is environment-friendly, has low acute toxicity to beneficial arthropods such as powdery insects and the like, has low toxicity to natural enemies of insects, and is suitable for resistance management of pests and comprehensive control of pests.

Cyantraniliprole is a second generation of ryanodine receptor inhibitor insecticides successfully developed by DuPont company following Chlorantraniliprole (DuPont product trade name is KANGWI). The chlorantraniliprole and the flubendiamide have similar structures and have diamide units, so the chlorantraniliprole is called as a novel diamide insecticide. Is an upgraded product of chlorantraniliprole and is known as the second generation of the health and breadth product. Cyantraniliprole controls pests by activating the ryanodine receptor of the target pest. Activation of the ryanodine receptor releases calcium ions stored in smooth muscle and striated muscle cells, which results in impaired muscle motor regulation, paralysis and ultimately death of the pest. The drug shows extremely obvious selectivity difference to mammals and pests, namely the ryanodine receptor, greatly improves the safety to the mammals, other vertebrates and other natural enemies, and has the following characteristics:

(1) the second generation ryanodine receptor preparation insecticide, cyantraniliprole, is prepared by changing various polar groups on a benzene ring, and is more efficient.

(2) The insecticidal composition is suitable for wide crops, can effectively control lepidoptera, homoptera and coleoptera pests, and particularly has excellent control effect on piercing-sucking mouthpart pests.

(3) High efficiency, low toxicity, novel action mechanism, safety to non-target and organism, and no cross resistance with the prior pesticide.

(4) Due to the systemic property of cyantraniliprole, the cyantraniliprole can be used in various ways, including spraying, root irrigation, soil mixed application, seed treatment and the like.

(5) Has low toxicity to birds, fishes, mammals, earthworms and soil microorganisms, and can be rapidly degraded in the environment.

Cyantraniliprole can be used for controlling pests of vegetables, fruit trees and various farmland crops, such as cabbage looper, cabbage aphid, prodenia litura, ladybug, whitefly, cotton bollworm, red spider, aphid, striped flea beetle and the like.

Aphids, also known as greates and mealworms, are a group of phytophagous insects including all members of the aphid superfamily (also known as aphid superfamily, scientific name: Aphidoidea). A total of 10 aphids have been found, of which there are about 4400, most of which belong to the Aphididae family. Aphids are also one of the most destructive pests on earth, of which approximately 250 are the pests with serious damage to agriculture, forestry and horticulture, and the aphids are of different sizes and have lengths ranging from one to ten millimeters.

Aphids are distributed very widely throughout the world, but are mainly concentrated in temperate regions. In addition, species diversity is much lower in the tropical zone than in the temperate zone. Aphids can migrate remotely and are mainly diffused in a mode of floating with wind; for example, the lettuce aphid is believed to be transmitted in this way from new zealand to tasmania, and some human activities may also aid in the migration of aphids, such as during transport of aphid-adhering plants.
