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

Embodiment 1

[0020] Pyridaben suspending agent, including by mass: 3-60 parts of pyridaben, 1-47 parts of auxiliary agent, 15-58 parts of water, said auxiliary agent refers to 8-15 parts of dispersant, 2 parts ~7 parts of wetting agent, 3 parts~15 parts of antifreeze agent, 1 part~6 parts of stabilizer, 1 part~4 parts of defoamer.

[0021] The dispersant is prepared by mixing one or more of sodium tripolyphosphate, sodium lignosulfonate, NNO (naphthalenesulfonic acid formaldehyde condensate), calcium lignosulfonate, and polyoxyethylene oxypropylene ether Into a dispersant.

[0022] Described wetting agent is tea dead, saponin, sodium lauryl sulfate, sodium lauryl polyoxyethylene ether sulfate, sodium dodecylbenzenesulfonate, octylphenol polyoxyethylene ether sulfate, SOPA Sauber , pull open powder, penetrant T (diethyloctyl sulfosuccinate sodium salt), penetrant JFC (fatty alcohol polyoxyethylene ether), Tween 80, take one or two or more to prepare a wetting agent.

[0023] The stabiliz...

Embodiment 2

[0027] According to the mass, it includes 20-45 parts of pyridaben, 2-45 parts of auxiliary agent, 18-50 parts of water, and the auxiliary agent refers to 10-13 parts of dispersant, 3-6 parts of wetting agent, 5-13 parts of antifreeze, 2-5 parts of stabilizer, 2-3 parts of defoamer, 2-5 parts of thickener. The selected auxiliary kind is the same as the kind described in embodiment 1.

Embodiment 3

[0029] According to the quality, it includes 18.2 parts of pyridaben, 3.8 parts of wetting agent teaku, 10 parts of dispersant sodium lignosulfonate, 14 parts of antifreeze glycerin, 3.5 parts of antifoaming agent organosilicone, and 6 parts of stabilizer tributyl phosphate , 4.5 parts of thickener xanthan gum and 40 parts of water are used to prevent and control red spider mite in apple trees and citrus trees in practice. The dosage is 60mg / kg, and the control effect is 94.27%, 86.64% respectively. The control effect of the control agent 15% pyridaben EC was 57.12%.

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...
