Problems solved by technology

[0004] In the actual process, the application of chemical agents is the most effective means of preventing and controlling plant diseases and insect pests, but the continuous application of a single chemical acaricide in high doses for a long time is likely to cause a series of problems such as drug residues and environmental pollution, while a reasonable chemical acaricide Agent compounding or mixing has the ability to expand the acaricidal spectrum, which is one of the most effective methods to solve the above problems

Embodiment 1

[0043] Embodiment 1 (77% pyridaben·fenoxycarb wettable powder)

[0044] Formula: pyridaben, 70%; fenoxycarb, 7%; wetting agent sodium lauryl sulfate, 2%; dispersant agent calcium lignosulfonate, 8%; filler silica, 18%, filler kaolin ,margin.

Embodiment 2

[0045] Embodiment 2 (63% pyridaben·fenoxycarb wettable powder)

[0046] Formulation: pyridaben, 56%; fenoxycarb, 7%; wetting agent sodium lauryl sulfate, 2%; dispersant agent calcium lignosulfonate, 8%; filler silica, 18%, filler kaolin ,margin.

[0047] 2. Microemulsion

Abstract

The invention provides an agricultural acaricidal composition and application thereof, and belongs to the field of acaricides. The acaricidal composition selects effective components pyridaben and fenoxycarb for compounding, and the acaricidal composition has the characteristics of high acaricidal activity, long lasting time, low toxicity, environmental protection and the like. The acaricidal composition comprises effective components, namely pyridaben and fenoxycarb, wherein the mass ratio of pyridaben to fenoxycarb is (40: 1)-(1: 40). The pyridaben and the fenoxycarb are reasonably compounded, so that the prevention and treatment range of the pesticide can be expanded, and the effects of improving pesticide effect and delaying pesticide resistance are achieved. The acaricidal compositioncan be used as an agricultural acaricide and can be used for preventing and treating pests with piercing-sucking mouthparts and especially has obvious effects on phytophagous mites, citrus red mites,aphids, phylloxera, whiteflies, scale insects, cabbage caterpillars, plutella xylostella, leaf miners and the like and has great popularization and use prospects.

Description

technical field [0001] The invention belongs to the field of pesticides, in particular to the field of agricultural acaricides, in particular to an agricultural acaricide composition and its application. Background technique [0002] Pyridaben (2-tert-butyl-5-(4-tert-butylbenzylthio)-4-chloropyridazin-3-(2H)one) is a broad-spectrum, contact acaricide, which can be used to control multiple Planting feeding harmful mites has a good effect on the whole growth period of mites, that is, eggs, young mites, nymphs and adults, and it also has obvious quick-killing effect on adult mites in the moving stage. The dosage of pyridaben is small, the initial effect is good, the effect is long, and it is less affected by temperature and insect state. No matter it is used in early spring or autumn, it can achieve satisfactory results. [0003] Fenoxycarb (2-(4-phenoxyphenoxy) ethyl carbamate) is a non-terpene insect growth regulator acaricide with juvenile hormone activity, because it has b...
