Whitefly, Bemisia tabaci, aphids, thrips and other piercing-sucking pests, due to their fast reproduction speed, long migration distance, rapid emergence of drug resistance, and serious harm, huge manpower and material resources are invested in prevention and control every year. The pests have developed strong resistance to these commonly used pesticides.
I would like to recommend an excellent insecticide, dinotefuran, for the treatment of piercing-sucking pests such as resistant whitefly, bemisia tabaci, aphids, thrips, etc. It has good effect and long lasting effect.
1. Introduction to the drug
Dinotefuran is a third-generation nicotinic insecticide developed by Japan's Mitsui Company in 1998. It has no cross-resistance with other nicotinic insecticides, and has contact and stomach toxicity. At the same time, it also has good systemic absorption It has the characteristics of high speed, high activity, long lasting effect, wide insecticidal spectrum, etc., and has excellent control effect on piercing and sucking pests, especially rice planthopper, Bemisia tabaci, whitefly, etc. that have developed resistance to imidacloprid Pests have special effects. The insecticidal activity is 8 times that of second-generation nicotines and 80 times that of first-generation nicotines.
2. the main advantages、
(1) Broad insecticidal spectrum: Dinotefuran can kill aphids, rice planthoppers, whiteflies, bemisia tabaci, thrips, stink bugs, leafhoppers, leafminers, flea beetles, mealybugs, leafminers, Dozens of pests such as leaf miners, peach heartworm, rice borer, diamondback moth, cabbage caterpillar, etc., and are highly effective against hygienic pests such as fleas, cockroaches, termites, houseflies, and mosquitoes.
(2) No cross-resistance: Dinotefuran has no cross-resistance with nicotinic pests such as imidacloprid, acetamiprid, thiamethoxam, clothianidin, and has developed resistance to imidacloprid, thiamethoxam, and acetamiprid. Pest activity is high.
(3) Good quick-acting effect: Dinotefuran is mainly combined with acetylcholinesterase in pests, disturbing the nervous system of pests, causing paralysis of pests, and achieving the purpose of killing pests. After application, it can be quickly absorbed by roots, stems and leaves of crops, And pass it to all parts of the plant to quickly kill the pests. Generally, 30 minutes after the application, the pests are poisoned and no longer feed, and the pests can be killed within 2 hours.
3. (4) Long lasting effect: After spraying, dinotefuran can be quickly absorbed by the roots, stems and leaves of plants, and transmitted to any part of the plant, where it exists in the plant for a long time to achieve the purpose of continuously killing pests. The validity period is more than 4-8 weeks.
(5) Strong penetrability: Dinotefuran has a high osmotic effect, and can penetrate well from the leaf surface to the back of the leaf after application. The granules can still be used under the condition of dry soil (soil moisture at 5%). Play a stable insecticidal effect.
(6) Good compatibility: dinotefuran can be combined with spirotetramat, pymetrozine, nitenpyram, thiamethoxam, thiazide, pyriproxyfen, acetamiprid, etc. For mixing, the synergistic effect is very significant.
(7) Good safety: Dinotefuran is very safe for crops. Under normal circumstances, it will not cause phytotoxicity. It can be widely used in wheat, rice, cotton, peanuts, soybeans, tomatoes, watermelons, eggplants, peppers, Cucumbers, apples and many other crops.
3. Main dosage forms
Dinotefuran has contact killing and stomach poisoning effects, and also has strong renal permeability and systemic absorption. At present, the dosage forms registered and produced in my country are: 0.025%, 0.05%, 0.1%, 3% granules, 10%, 30%, 35% soluble 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, peanuts, soybeans, cucumbers, watermelons, melons, tomatoes, eggplants, peppers, beans, potatoes, apples, grapes, pears and other crops. 5. The control objects are mainly used for the control of aphids, rice planthoppers, whiteflies, bemisia tabaci, thrips, lycium bugs, green bugs, leafhoppers, leaf miners, flea beetles, mealybugs, scale insects, American spots Minor flies, leaf miners, peach worms, rice borers, diamondback moths, cabbage caterpillars and other dozens of pests, and are highly effective against fleas, cockroaches, termites, houseflies, mosquitoes and other hygienic pests.
6. Use technology
(1) Soil treatment: Before sowing wheat, corn, peanuts, soybeans and other crops, use 1 to 2 kg of 3% dinotefuran granules per mu for spreading, furrow or hole application, which can effectively control aphids, white powder The damage of lice, Bemisia tabaci, leafhoppers and other pests can last for more than 50 days.
(2) Cucumber, tomato, pepper, summer squash, watermelon, strawberry and other crops cultivated in greenhouses, when planting, use dinotefuran granules for hole application, which can effectively control greenhouse whiteflies, Bemisia tabaci, aphids, etc. Pests can also treat viral diseases, and the duration of validity can reach more than 80 days.
(3) Seed dressing with pesticides: Before sowing wheat, corn, peanuts, potatoes and other crops, 8% dinotefuran suspension seed coating can be used for seed dressing according to the ratio of 1450-2500g/100kg seeds, which can also effectively control seedlings It can prevent the harm of a variety of sucking pests such as aphids, whiteflies, and bemisia tabaci, and can also treat underground pests such as grubs and golden needle insects.
(4) Spraying control: When the crops such as cowpea, tomato, pepper, cucumber, eggplant and other crops are seriously damaged by Bemisia tabaci, whitefly, thrips and other pests, 40% Pyramid and Dinotefuran Aqueous Dispersible Granules 1000～1500 can be used. Double liquid, or 1000~1500 times liquid of 30% spirulina·dinotefuran suspension, or 2500~3000 times liquid of 60% enidine·dinotefuran water dispersible granules, spray evenly, which can effectively control whitefly and bemisia tabaci , the spread of thrips and other pests.
