Imidacloprid: also known as Kang Fuduo, 蚜虱 ,, 虱蚜 虱蚜, Gao Qiao, Bi Dan. It is a selective low-toxic insecticide with a strong systemic insecticidal effect. It has a good effect on sucking mouthparts pests, but it is not effective against mites and nematodes, because it has a strong internal squirt. The insect effect can be directly used for soil treatment or seed treatment. The insecticidal mechanism is also applied to the nervous system of the pest, so that the pest loses the nerve conduction function and finally kills the pest, which has a good effect on controlling various rice planthoppers. It is advisable to adopt a radical cure and control the control strategy of the second generation. During the peak period of adult parasite spread, the second and third generation nymphs will be controlled at the peak of the incubation period, with 20% concentrated soluble 7~10mg per 667m2, or 10% per 667m2. Wettable powder 50~100g. To control the greenhouse or open field whitefly, in the ascending period of the nymphal worm, use 20% concentrated solvent 15~30ml per 667 m2, spray on water, control 5~8ml of cabbage caterpillar, spray on water. Cotton pests are treated with 70% wet dressing for cotton seeding. This is because it has a strong systemic action. It is absorbed by the roots after seed dressing. It can control aphids in cotton seedlings, every 667m2500~714g, add water 1.5~2L, mix In a paste, mix 1000g of cotton, cut it evenly and then sow. The control of pear hibiscus should be sprayed with 20% concentrated solvent 2500~5000 times in the egg stage and the first generation nymph. The germination rate of citrus leaf miner in the field is 25% with 1000~2000 times liquid spray. Apple jaundice should be sprayed with 5000~6000 times liquid when the insect mouth rises.
Diflubenzuron: It is a selective low-toxic insecticide. Its mechanism of action is the same as that of acetamiprid. The insecticidal rate is slow, the efficacy period is 15~20 days, it can withstand rainwater scouring, and it is safer for beneficial insects. It is characterized by its effectiveness against a wide range of pests. It is ineffective for sucking mouthparts such as aphids, spider mites and planthoppers. Controlling dry crop pests such as armyworms, in the 2nd instar larvae, use 25% suspension agent 100~150ml per 667m2, spray on water, cotton bollworm, red bollworm, corn borer and other pests in the egg hatching period or beginning At the peak of the instar larvae, water sprayed with 25% suspension agent 100~150ml per 667m2, bridgeworm, cotton leaf moth, and moth, etc., sprayed with 75~100ml per 667m2 in the 2nd instar larvae. Pests such as Pieris rapae, Cabbage worm, Spodoptera litura, Spodoptera exigua, etc. should be used in the 2nd instar larvae, with 25% suspension agent 50~100ml per 667m2, Plutella xylostella in the 1st to 2nd instar larvae, every 667m2 Spray water with 25% suspension 100~150ml. Pests such as apple leaf roller moth, citrus leaf roller moth, pear star caterpillar, boat-shaped caterpillar, moth, moth, etc. can be sprayed with 25% suspension agent 1000-2000 times. Tobacco budworm is sprayed with 25% suspending agent 100~150ml in the egg priming period or the larvae of the early larvae (Note: This product can not be mixed with alkaline substances, and it is forbidden to use in mulberry garden and silkworm field).
