preparation example Construction

[0028] The present invention also provides the preparation method of above-mentioned shaman emulsifiable concentrate:

[0029] Add the above-mentioned components into the mixing reaction kettle in turn, and stir evenly to obtain the product.

Embodiment 1

[0032] Dissolve 350g Daphne genkwa, 150g star anise maple leaf, 250g baicalin, 350g Baibu, 250g chamaejamas, 400g and 350g cnidium in 5kg of ethanol solution, heat and reflux extraction twice, each time for 3 hours, and filter the extract , the extract is concentrated to a paste, pulverized, and dried.

Embodiment 2

[0034] Add 250 g of the Chinese medicine composition extract of Example 1, 90 g of dicofol, 120 g of pyraclofen, 80 g of profenofos, 650 g of the organic solvent xylene and 30 g of the emulsifier calcium dodecylbenzenesulfonate into the mixing reaction kettle in sequence, and stir Evenly, that is.

[0035] drug effect

[0036] The Shaman emulsifiable concentrate prepared in Example 2 was applied to prevent and treat Panonychus on sweet oranges. The emulsifiable concentrate was diluted with water by 5000 times and sprayed, and the control effect was 98.2% 15 days after application.

[0037] This embodiment 2 is applied to the prevention and treatment of Tetranychus urticae on strawberries, the emulsifiable concentrate is diluted with water by 5000 times and sprayed, and the control effect is 96.9% 15 days after application.

Abstract

The invention provides a novel acaricidal missible oil, which comprises a Chinese medicinal composition extract, dicofol, fenpyroximate, profenofos, an organic solvent xylene and an emulsifier calcium dodecyl benzene sulfonate. By adopting composite insecticidal components and the Chinese medicinal composition extract, the insecticidal and acaricidal effects are improved. With good safety, the acaricidal composite missible oil meets the efficient and safe insecticidal needs of crop protection.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a novel acaricidal compound emulsifiable concentrate. Background technique [0002] In the actual process of agricultural production, the most likely problem in the control of pests is the generation of insecticide resistance of pests and mites. Agriculturally important pest mites are particularly prone to resistance due to their short reproductive cycle, large reproductive capacity, low mobility, and high degree of selfing. In some areas where mites are seriously infested, common acaricides such as dicofol and fenflux have no effect when used alone. Abamectin has also caused serious resistance due to its large-scale application. [0003] One way to control agriculturally resistant pest mites is to introduce new ingredients that are not cross-resistant with existing species. However, the development cost of new active ingredients is high, the development cycle is long, and ...
