||Mode of action Systemic insecticide with translaminar activity and with contact and stomach action. Readily taken up by the plant and further distributed acropetally, with good root-systemic action. Uses Control of sucking insects, including rice-, leaf- and planthoppers, aphids, thrips and whitefly. Also effective against soil insects, termites and some species of biting insects, such as rice water weevil and Colorado beetle. Has no effect on nematodes and spider mites. Used as a seed dressing, as soil treatment and as foliar treatment in different crops, e.g. rice, cotton, cereals, maize, sugar beet, potatoes, vegetables, citrus fruit, pome fruit and stone fruit. Applied at 25-100 g/ha for foliar application, and 50-175 g/100 kg seed for most seed treatments, and 350-700 g/100 kg cotton seed. Also used to controls fleas in dogs and cats.

Imidacloprid is a low-toxic insecticide. The acute oral LD50 of rats (male and female) was about 450 mg/kg, and the acute oral LD50 of mice was about 150 mg/kg. Rats (male, female) acute percutaneous LD50>5g/kg, acute inhalation LC50 (4 hours) >5323mg/m3 (powder), 69mg/m3 air (aerosol).
The two-year feeding test had no effect dose: 100 mg/kg feed for male rats, 300 mg/kg feed for female rats, and 330 mg/kg feed for mice. The dog (52 weeks) feeding test had an inactive dose of 500 mg/kg feed. The ADI for humans was 0.057 mg/kg body weight.
No irritation to rabbit eyes and skin, no mutagenicity, teratogenicity and sensitization. Golden round belly larvae LC50 (96 hours) 237mg/L. Rainbow trout LC50 (96 hours) 211 mg / L.
It is used to control sucking mouthparts pests such as aphids, spider mites, planthoppers, thrips, whiteflies and their resistant lines. It is also effective against Coleoptera, Diptera and Lepidoptera. Imidacloprid is inactive against nematodes and spider mites. Due to its excellent systemic properties, it is particularly suitable for seed treatment and application in granules.
In the cereal crops, corn, rice, potato, sugar beet and cotton, the pests can be continuously controlled early, and the crops and citrus, deciduous fruit trees, vegetables and other late growth pests can be sprayed on the surface. Foliar spray has excellent protection against black-tailed spider mites, planthoppers (rice brown planthopper, gray planthopper, white-backed planthopper), aphids (taotao, cotton aphid) and thrips (greenhouse fence horse) It is superior to buprofezin, etoilerin, anti-carbocarb and chlorpyrifos.
Soil treatment, seed treatment and foliar spray can be used.
(1) When the soil concentration is 1.25mg/kg, it can be used for a long time to control the peach aphid on the cabbage and the bean mites on the broad bean.
(2) When controlling rice brown planthopper, white backed planthopper, spider mites and thrips, the dosage is 20 ~ 30g / hm2, the effect is rapid, the effect period is long, and more than 90% of the control effect can be maintained for more than 40 days. There is good selectivity between the locust and the natural enemies. It is ideal for the control of small rice stripe disease caused by Laodelphax striatellus, common dwarf disease transmitted by black-tailed spider mites and yellow dwarf disease when used in seedbed or buckwheat soil treatment.
(3) It has excellent control effects on a variety of aphids, including orchards that produce high levels of resistance to various insecticides. With the active ingredient of 15 ~ 30g / hm2, water spray (5000 ~ 20000 times liquid) can effectively control peach aphid, wheat bran, rapeseed meal and cotton aphid, more than 90% of the control effect can be more than 1 month.
(4) Prevention and control of wheat ear mites, with increasing dose control effect, the use of 25% wettable powder 75g/hm2 after the occurrence of sorghum has a relatively stable and ideal control effect, and the use of 25% in acres during the flowering period can be used. Wet powder 150g/hm2 is suitable to ensure a long enough duration.
(5) Treated with 1g ai/kg seed, can control soybean meal and cotton aphid for at least 5 weeks.
(6) Pharmacodynamics of resistant pests: Since imidacloprid is different from organophosphorus, carbamate and pyrethroid insecticides, it has resistance to aphids, spider mites and planthoppers that have been resistant to conventional insecticides. excellent results. The resistant black-tailed spider mites, brown planthopper, and the white planthopper are not sensitive to organophosphorus and carbamate, and the peach aphid is also insensitive to organophosphorus, carbamate and pyrethroid and pyrethroid insecticides. The sensitivity of the resistant strain to imidacloprid was not reduced compared to the susceptible strain.
