The stinging pests such as whitefly, bemisia tabaci, aphids and thrips have developed strong resistance to these commonly used pesticides because of their fast propagation speed and long distance of flight, resulting in rapid resistance and serious harm. Huge manpower and material resources are invested in prevention and control every year. With the increase of drug use, the pests have developed strong resistance to these commonly used pesticides. Today, xiaobian will recommend an excellent insecticide – dinotefuran, specifically for the treatment of resistance to whitefly, bemisia tabaci, aphids, thrips and other stinging pests, good effect, long duration of efficacy.
1. Pharmaceutical introduction
Dinotefuran is the third generation nicotinic insecticide developed by Mitsui Company in 1998. It has no cross resistance with other nicotinic insecticides, and has the effects of contact and stomach toxicity. At the same time, it also has good internal absorption, high rapid effect, high activity, long duration of effect, wide insecticidal spectrum and other characteristics, and has excellent control effect on stinging sucking mouth pests. Especially to imidacloprid has produced resistance to rice planthopper, bemisia tabaci, whitefly and other pests have special effects. The insecticidal activity was 8 times that of the second generation and 80 times that of the first generation.
2. Main advantages
(1) wide insecticidal spectrum: cefuroxime worm amine can kill aphid, rice planthopper, whitefly, whiteflies, thrips, bugs, leafhoppers, leaf like flies, jump a pest, powder, spot hidden fly, small leaf moth, peach budworm, rice borers, plutella xylostella, caterpillar, such as dozens of pests, and the fleas, cockroaches, termites, housefly, mosquitoes and other health pests are efficient.
(2) No cross-resistance: Dinotefuran has no cross-resistance to nicotinoid pests such as imidacloprid, acetamiprid, thiamethoxam and thiamethoxam, and has high activity to those pests that have developed resistance to imidacloprid, thiamethoxam and acetamiprid.
(3) Good rapidity: Cefuroxime pest insect amines and acetylcholinesterase in the body, disrupt the pests of the nervous system, causing paralysis, pest to kill pests, pesticide, can be quickly absorbed by the crop root leaf, and pass to all parts of the plant, a quick kill pests, generally 30 minutes, after applying pesticide pests occur poisoning, namely no longer feeding, 2 hours to kill pests.
(4) Long duration of efficacy: After spraying, dinotefuran can be quickly absorbed by the roots, stems and leaves of plants, and transferred to any part of the plant. It can exist in the plant for a long time to achieve the purpose of killing pests continuously, and the duration of efficacy can be longer than 4-8 weeks.
(5) Strong permeability: Dinotefuran has a high osmotic effect, which can well penetrate from the leaf surface to the back of the leaf after application. Under the condition of dry soil (soil water content is 5%), the granules can still play a stable insecticidal effect.
(6) Good mixing: Dinotefuran can be mixed with spiroworm ethyl ester, pyraphzone, alidinamide, thiamethoxam, thiazinone, pyripropyl ether, acetamiprid and other agents for the prevention and control of spiking pests, and the synergistic effect is very significant.
(7) Good safety: Dinotefuran is very safe for crops. Under normal circumstances, it will not cause harm. It can be widely used in wheat, rice, cotton, peanut, soybean, tomato, watermelon, eggplant, pepper, cucumber, apple and other crops.
3. Main dosage forms
Dinotefuran has the effect of touch and stomach toxicity, but also has a strong kidney permeability and internal absorption, the use of multi-purpose, dosage forms are also many. At present, the dosage forms registered for production in China are: 0.025%, 0.05%, 0.1%, 3% granules, 10%, 30%, 35% soluable granules, 20%, 40%, 50% soluble granules, 10%, 20%, 30% suspending agent, 20%, 25%, 30%, 40%, 50%, 60%, 63%, 70% water dispersible granules.
4. Applicable crops
Dinotefuran can be widely used in wheat, corn, cotton, rice, peanut, soybean, cucumber, watermelon, melon, tomato, eggplant, pepper, bean, potato, apple, grape, pear and other crops.
5. prevention and control objects
Is mainly used in the prevention and control of aphids, rice planthopper, whitefly, whiteflies, thrips, blind bugs like blind, green bugs, leafhoppers, leaf flies, jump a pest, powder, scale insects, americas spot hidden fly, small leaf moth, peach budworm, rice borers, plutella xylostella, caterpillar, such as dozens of pests, and the fleas, cockroaches, termites, housefly, mosquitoes and other health pests are efficient.
