Piercing-sucking pests such as whiteflies, whiteflies, aphids, and thrips have a fast reproduction rate, long migration distance, rapid resistance to pesticides, and serious damage. Huge manpower and material resources are invested every year for prevention and control. With the increase in the number of times the pesticides are used, the pests have developed strong resistance to these commonly used pesticides. Today, I recommend an excellent insecticide to everyone-dinotefuran, which is specially used to treat resistant whiteflies, whiteflies, aphids, thrips and other piercing-sucking pests, with good effects and long lasting effect.
1. Introduction to the agent
Dinotefuran is a third-generation nicotine insecticide. It has no cross-resistance with other nicotine insecticides, has contact and stomach poison effects, and at the same time, it also has good systemic absorption, high rapidity, high activity, long lasting effect, and a wide insecticide spectrum.
It has excellent preventive effect on piercing-sucking mouthparts pests, especially for rice planthoppers, whiteflies, whiteflies and other pests that have developed resistance to imidacloprid. The insecticidal activity is 8 times that of the second-generation nicotine and 80 times that of the first-generation nicotine.
2. Main advantages
(1) Broad insecticidal spectrum: Dinotefuran can kill dozens of pests such as aphids, rice planthoppers, whiteflies, whiteflies, thrips, stink bugs, leafhoppers, leafminers, flea beetles, mealybugs, leafminers, leafminers, peach borers, rice borers, diamondback moths, cabbage worms, etc., and is highly effective against sanitary pests such as fleas, cockroaches, termites, houseflies, mosquitoes, etc.
(2) No cross-resistance: Dinotefuran has no cross-resistance with nicotine pests such as imidacloprid, acetamiprid, thiamethoxam, and clothianidin, and has high activity against pests that have already developed resistance to imidacloprid, thiamethoxam, and acetamiprid.
(3) Good quick-acting property: Dinotefuran mainly binds to acetylcholinesterase in the pests, disrupts the pests' nervous system, causes paralysis, and kills the pests. After application, it can be quickly absorbed by the roots, stems, and leaves of crops and transferred to various parts of the plants, killing the pests quickly. Generally, the pests are poisoned 30 minutes after application and stop feeding. The pests can be killed in 2 hours.
(4) Long lasting effect: After spraying, Dinotefuran can be quickly absorbed by the roots, stems, and leaves of plants and transferred to any part of the plants. It exists in the plant for a long time, achieving the purpose of continuous killing of pests. The lasting effect is more than 4-8 weeks.
(5) Strong permeability: Dinotefuran has a high permeability. After application, it can penetrate well from the leaf surface to the back of the leaf. The granules can still exert a stable insecticidal effect under dry soil (soil moisture at 5%) conditions.
(6) Good compatibility: Dinotefuran can be mixed with spirotetramat, pymetrozine, nitenpyram, thiamethoxam, buprofezin, pyriproxyfen, acetamiprid and other pesticides for controlling piercing-sucking pests, and the synergistic effect is very significant.
(7) Good safety: Dinotefuran is very safe for crops. Under normal circumstances, it will not cause pesticide damage. It can be widely used on wheat, rice, cotton, peanuts, soybeans, tomatoes, watermelons, eggplants, peppers, cucumbers, apples and many other crops.
3. Main dosage forms
Dinotefuran has contact and stomach poisoning effects, and also has strong kidney permeability and systemicity. It can be used in many ways and has many dosage forms. At present, the dosage forms registered for production in my country include: 0.025%, 0.05%, 0.1%, 3% granules, 10%, 30%, 35% soluble solutions, 20%, 40%, 50% soluble granules, 10%, 20%, 30% suspensions, 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. Target of control
It is mainly used to control dozens of pests such as aphids, rice planthoppers, whiteflies, Bemisia tabaci, thrips, blind bugs, green stink bugs, leafhoppers, leafminers, flea beetles, mealybugs, scale insects, American leafminers, leafminers, peach borers, rice borers, diamondback moths, cabbage worms, etc. It is also highly effective against sanitary pests such as fleas, cockroaches, termites, houseflies, mosquitoes, etc.
6. Application technology
(1) Soil treatment: Before sowing crops such as wheat, corn, peanuts, and soybeans, use 1 to 2 kg of 3% dimethoate granules per mu for spreading, furrow application, or hole application. It can effectively control the damage of aphids, whiteflies, Bemisia tabaci, leafhoppers, etc., and the effective period can reach more than 50 days.
(2) For crops such as cucumbers, tomatoes, peppers, zucchini, watermelons, and strawberries grown in greenhouses, dimethoate granules can be applied to holes during planting to effectively control greenhouse whiteflies, whiteflies, aphids, and other pests in the greenhouse. It can also treat viral diseases and last for more than 80 days.
(3) Seed dressing with pesticides: Before sowing crops such as wheat, corn, peanuts, and potatoes, 8% dimethoate suspension seed dressing can be used at a drug-seed ratio of 1450-2500 g/100 kg of seeds. It can also effectively control aphids, whiteflies, whiteflies, and other piercing-sucking pests in the seedling stage. It can also treat underground pests such as white grubs and wireworms.
(4) Spray control: When cowpea, tomato, pepper, cucumber, eggplant and other crops are seriously damaged by pests such as whiteflies, whiteflies and thrips, 40% pyriproxyfen·dinotefuran water dispersible granules (1000-1500 times diluted), or 30% spirothiazolin·dinotefuran suspension (1000-1500 times diluted), or 60% oxadiazine·dinotefuran water dispersible granules (2500-3000 times diluted) can be evenly sprayed to effectively control the spread of pests such as whiteflies, whiteflies and thrips.
