Thiamethoxam is the second generation of neonicotinoid insecticide. Due to its slow effect and strong resistance, its control effect is getting worse and worse. Today, I would like to introduce an excellent insecticide with higher activity than thiamethoxam, which is Clothianidin
What is clothianidin
clothianidin by bayer company and Japan Takeda Takeda companies to jointly develop a new type of pesticides, is the imidacloprid, thiamethoxam oxazine after the development of the second generation of new neonicotinoid insecticides, compared with the first generation, to take a broader insecticidal activity is higher, better security, the effective longer, toxicity is greatly reduced, is an effective and safe, high selectivity of new pesticides, It has the advantages of high efficiency, broad spectrum, low dosage, low toxicity, long efficacy period, no harm to crops, safe use, and no cross resistance to conventional pesticides. It has the function of internal absorption and penetration, and is another variety to replace highly toxic organophosphorus pesticides.
The advantages of clothianidin
(1) Wider insecticidal spectrum: clothianidin has tactile, gastric toxicity and endosuction activities. It is widely used to prevent and control garlic maggots, root maggots, onion maggots, ground maggots, ground tigers, golden needle insects and other underground pests, as well as aphids, thrips, planthoppers, whitefly, bemisia tabaci, rice planthoppers and more than 10 kinds of stinging insects.
(2) Long retention period: clothianidin is not easy to be leached in soil. This makes thiamethoxam not easy to decompose underground, with higher utilization rate and longer retention period than thiamethoxam and imidacloprid. According to the test, the retention period of foliar spray can reach 30 days, and the retention period of soil treatment can reach 6 months.
(3) High activity: Thiamethoxam is a nicotinoid insecticide developed after imidacloprid and thiamethoxam. It mainly acts on acetylcholine receptors in insects, and has higher affinity and insecticidal activity to insect acetylcholine receptors than imidacloprid. It is also more active than thiamethoxam and imidacloprid, and has some effect on chewing pests.
(4) Easy to use: thiamethoxam has strong permeability and internal absorption conductivity, mainly to touch and stomach toxicity, not only can be used for spray, but also can be used for seed mixing, soil treatment, root irrigation, root dipping, root dipping and other methods of use. All have very good insecticidal effect.
(5) Good safety: the toxicity of clothianidin to environmental insects is greatly reduced, and it is safer for crops and more assured to use. Can be used in rice, vegetables, fruit trees and other crops.
Control range
clothianidin in rice, wheat, corn, peanuts, Chinese cabbage, cabbage, tomato, eggplant, cucumber, potato, citrus trees, apple trees, pear, watermelon, Chinese wolfberry, tea tree used on a variety of crops, and 20 are widely used in the prevention and control of aphids, leafhoppers, thrips, planthoppers, leafhoppers, half a spectacle, mirid bugs, such as caterpillar and 20 kinds of coleoptera some, diptera and lepidoptera pests
Usage
(1) The control of peanut, potato, garlic maggots, grubs and other underground pests, can be used before sowing, 48% clothianidin suspension seed coat agent according to the ratio of 250-500 ml /100 kg seeds for seed mixing, evenly wrapped on the seed surface, can effectively prevent the harm of garlic maggots, grubs, gold needle worms and other underground pests. The retention period can reach about 6 months.
(2) For the prevention and control of underground pests such as garlic maggots and leek maggots, 3000 times of 20% clothianidin suspension solution can be used in the early stage of larval emergence together with irrigation water to effectively kill underground pests such as garlic maggots and leek maggots, and the duration of efficacy can reach more than 60 days.
(3) To prevent and control wheat aphid, maize thrips, rice planthopper and other stinging pests, 20 ~ 40 ml of 20% pyrhid · clothianidin suspension and 30 kg of water can be evenly sprayed at the early stage of occurrence, which can effectively prevent the continued harm of pests. The retention period is up to 30 days.
