Damanling suspension agent

Abstract

The utility model discloses a pyridaben suspending agent for killing mites. The utility model comprises 3 to 60 shares of pyridaben, 1 to 47 shares of promoter, 15 to 58 shares of water in mass ratio. The pyridaben suspending agent with a very high active component has a superhigh sensitivity in connection with the red spider mites on apple trees, citrus trees and the mites which have become resistant to the pyrethrum acaricide, and then can reduce the usage amount of the organic solvent. The utility model has the advantages of simple processing technology, low cost, being convenient in use, reducing spray times and the pollution to the environment and the fruit, reducing the toxicity influence to users, no peculiar smell, and being less inflammable. The pyridaben suspending agent is safer to transport and store, and the prevention effect on the red spiders on apple trees, citrus trees respectively reaches 89.89% to 95.87%, 86.64% to 91.48%, and is 40% to 30% higher than the prevention effect of the single pyridaben variety; the utility model reduces the agentia dosage and saves cost for the fruit growers.

Description

technical field [0001] The invention relates to an agricultural acaricide, in particular to a pyridaben suspension for killing mites. technical background [0002] The prior art uses a single agricultural acaricide to control red spiders and rust ticks in apple trees and citrus trees. This single-species acaricide has a high concentration of medication, and the number of times is too frequent and the interval is too short. Huge selection pressure is generated, forcing it to mutate and quickly produce drug resistance; when the adult and nymph peak period is used, drug resistance is also easy to develop. Moreover, the resulting drug resistance can be inherited as a multigenerational defect. [0003] Pyridaben (also known as pyridaben, speedaben, pyridaben) English name: pyridaben [0004] Structural formula: [0005] [0006] Molecular formula: C 19 h 25 ClN 2 OS [0007] Chemical name: 2-tert-butyl-5-(4-tert-butylbenzylthio-4-chloro-3(H)-pyridazin-3-one [0008] Th...

Problems solved by technology

Especially during the fruit period, in order to reduce the rate of black-skinned fruit and increase the value of commodities, pesticides are applied almost once a week, causing serious fruit pesticide pollution

Especially in one area, long-term, large-scale, and single use of the same pesticide can easily cause mites to develop resistance; unreasonable high-concentration pesticides, frequent times, and short intervals will generate huge selection pressure on mites , forcing it to mutate and produce drug resistance quickly; when the drug is used at the peak of adult and nymph mites, it is also easy to produce drug resistance

And the resulting drug resistance has the disadvantage of inheriting multigenerational
