Control of underground pests is the most important work to ensure that the seedlings are even and strong, since bayer launched imidacloprid in the 1990s, because of its good systemic conductivity and touch killing effect, it is widely used in spraying, seed mixing, soil treatment, and has become the most ideal agent for the control of various underground pests and aboveground pests such as moths, grubs, golden needle worms, aphids and so onal insects. However, due to years of use, these pests have developed a strong resistance to imidacloprid, and the control effect has been greatly reduced. Today, Xiaobian recommends an excellent insecticide for better control of underground aboveground pests, with higher activity than imidacloprid and better control effect.
Introduction to the agent
This excellent agent is thiamethoxazine is a neonicotinoid insecticide developed by Novartis in 1991, but until 2000, thiamethoxine entered the market, thiamethoxazine not only has the advantages of touch, gastric toxicity, good systemicity, etc., but also has higher activity, better safety, a wider insecticidal spectrum and fast action, long effectiveness and other characteristics, in 2011 for the first time beyond imidacloprid to become the world's largest sales of nicotinic fungicides, favored by farmers and friends. Compared with imidacloprid, thiamethoxazine has the following characteristics, which are incomparable to imidacloprid.
Main features
(1) The insecticidal spectrum is wider: thiocarbene has a good killing effect on coleoptera, diptera, lepidoptera and other pests, especially for aphids, whiteflies and other winged pests have higher activity, can effectively control all kinds of aphids, thrips, leafhoppers, planthoppers, ticks, ticks, grubs, potato beetles, nematodes, leafminer moths, rice planthoppers, rice bugs, long bugs, American grass blind bugs, mealy aphids, apple flower weevils, rice elephant beetles, rice elephant beetles, yellow striped jumping beetles, step beetles, sunflower leaf beetles, golden needle worms, apple worms, leaf latents, spotted flies and nematodes, etc. In addition, thiamethoxam can also be used in animal and public health to control pests such as flies.
(2) Higher activity: the main metabolite of thiamethoxine in insects is thiamethoxam, and the affinity of thiamethoxam to insect acetylcholine receptors is higher than that of thiamethoxam, with secondary insecticidal activity. Insecticidal activity is higher, with thiamethoxazine being more than 10 times more active than imidacloprid insecticidal activity.
(3) Higher solubility: thiamethoxam solubility in water is 8 times that of imidacloprid, therefore, even in the arid environment, it does not affect the absorption and utilization of crops on thiamethoxine, especially in wheat, corn, cotton, fruit trees and other crops, in the summer high temperature and drought conditions, insecticidal activity is higher.
(4) Longer effective period: thiamethoxine has the strongest systemic conduction effect and has a certain permeability. Because of its slow metabolism in plants and soils, it has a long period of biological activity, and the soil has a shelf life of more than 90 days, which basically ensures that most crops will not be harmed by aphids, whiteflies, and other stinging pests during the growth period.
(5) Promote growth: thiamethoxam can activate plant stress proteins, while the plant body auxin, cytokinin, gibberellin, abscisic acid, peroxidase, polyphenol oxidase, phenylalanine lysine lyase has an impact, thiamethoxazine in turn makes the crop stem more robust, the root system more developed, significantly enhance the ability to resist stress.
(6) No interaction resistance: Although thiamethoxazine is also a nicotinoid insecticide, it has no interaction resistance with other nicotinic agents such as imidacloprid, acetamidine, and alenazole, and the use of thiamethoxazine control effect is more prominent in areas where imidacloprid is resistant.
(7) Good mixing: thiamethoxine has a good mixing, can be with azoxystrobin, fine nail cream, clonylonitrile, phenyl ether methylcyclazole and other insecticide fungicides have a good mixing, insecticidal, disease treatment effect is more prominent.
(8) A variety of methods of use: thiamethoxine has a good gastric toxicity, touch killing effect, but also has a good systemicity, there are many ways to use, both for spraying, can also be used for seed mixing, soil treatment.
How to use
Thiamethoxine can be used in a variety of application methods such as seed mixing, spraying, soil treatment, and root irrigation.
Prevention and control objects
Thiamethoxam can be used to control aphids, thrips, whitefly, niacinalis, leafhoppers, grubs, golden needle worms, potato beetles, nematodes, leafminer moths, rice planthoppers, green blind bugs, rice bugs, long bugs, American pasture blind bugs, whitefly, apple weevils, rice weevils, yellow striped jumping beetles, step beetles, sunflower leaf beetles, apple beetle moths, leafminers, spotted flies and nematodes. In addition, thiamethoxazine can also be used in animal and public health fields, control of flies, etc.
Use technology
(1) Soil treatment: Before or when sowing wheat, corn, rice, cotton, peanuts and soybeans, use 4% of thiotiazide granules, 1 to 2 kg per mu, add 10 to 15 kg of fine soil and mix evenly, spread, strip, ditch, hole or sow with seeds, can effectively control a variety of pests in the soil.
(2) Seed treatment: Before sowing wheat, corn, cotton, soybeans, peanuts, rice and other crops, the dispersible powder treated with 70% thiamethoxine seeds is mixed according to the seed ratio of 100-140 g/100 kg seeds, and the seed coating agent is evenly wrapped on the seed surface, which can effectively control the harm of a variety of underground pests and aboveground pests.
(3) Root irrigation treatment: When tomatoes, watermelons, cucumbers, peppers, eggplants and other crops are colonized, the dispersible powder is treated with 30% thiamethoxine seeds, which can effectively prevent a variety of underground pests such as grubs and golden needle worms, and can also treat aphids, planthoppers, whiteflies and other pests.
(4) Pharmaceutical spray: In tomatoes, wheat, cotton and other crops with a long growth period, when aphids, whiteflies, whitefly and other pests occur in the later stage, 12% Avi thiamethoxine suspension agent can be used 12 to 15 ml / mu, and 30 kg to 50 kg of water can be uniformly sprayed, which can effectively control the harm of these pests.
Tip: Thiamethoxine insecticidal speed is slow, when used, it is best to use for soil treatment, or mixed with other fast-acting agents, the insecticidal effect is the best.
