preparation example Construction

[0055]The preparation method of the emulsion in water is as follows: dissolving the horse bean extract in a solvent, adding together an emulsifier and a co-emulsifier, and stirring at a high speed at normal temperature to obtain the horse bean water emulsion.

[0056] C. Microemulsion Weight Percent Formulation

[0057] Horse bean extract: 10-40%, emulsifier: 10-20%, co-emulsifier: 0.5-5%, water to make up 100%.

[0058] The emulsifier used in the microemulsion is one or more of styrene phenol polyoxyethylene ether, polyvinyl styrene phenol ether oleate, king phenol polyoxyethylene ether, biphenol polyoxyethylene ether, etc. The co-emulsifier is selected from one or more of linear alkanols such as ethanol, propanol, n-butanol, isobutanol, dodecanol-1, myristyl alcohol-1, stearyl alcohol-1 and the like.

[0059] The preparation method of the microemulsion is as follows: firstly mix the horse bean extract with a solvent, an emulsifier and a co-emulsifier evenly, add water drop...

preparation Embodiment 1

[0062] Take by weighing horse bean plant 60kg, pulverize, fine powder crosses 325 mesh sieves after pulverizing, wherein guarantees that 95% fine powder passes through 325 mesh sieves, this fine powder is with 30kg white carbon black, 5kg sodium lignosulfonate, 5kg After the dispersant NNO is fully mixed, a 60% bitter horse bean acaricidal wettable powder can be obtained.

[0063] The 500-800 times liquid of the prepared wettable powder (in which an appropriate amount of laundry can be added) can prevent and control harmful mites such as Tetranychus cinnabarinus, Tetranychus hawthorn, and Tetranychus urticae, and the control effect can reach more than 80%. The validity period is 7-10 days.

preparation Embodiment 2

[0065] Weigh 100 kg of horse bean plant, crush it to a coarse powder of 1 mm-5 mm, extract with 150 kg of industrial ethanol at 60° C. for 24 hours, and concentrate under vacuum to obtain horse bean extract (concentrate).

[0066] Take 10kg of horse bean extract, 10kg of ethyl acetate, 70kg of turpentine, 8kg of nonylphenol polyoxyethylene ether, and 2kg of calcium dodecylbenzenesulfonate, and mix them thoroughly to obtain 10% horse bean acaricidal emulsifiable concentrate.

[0067] The 500-800 times liquid of the prepared EC can effectively control various pests such as apple cinnabar spider mite, hawthorn spider mite, two-spotted spider mite and other harmful mites, and can also be used to control wolfberry aphid, wheat aphid, apple yellow aphid and other pests.

Abstract

The invention discloses a Swainsonia salsula Taub. acaricide and its preparation method. Swainsonia salsula Taub. Plants undergo a certain processing process to prepare a wettable pulvis, missible oil, an emulsion in water, a microemulsion and the like of the Swainsonia salsula Taub. acaricide. Tests prove that the acaricide of the invention has the advantages of substantial drug effect, high selectivity, low toxicity, low residual, difficult generation of pest mites' resistances to the acaricide, simple preparation technology, and low cost, accords with present pesticide development trends, and is suitable for the popularization and the application.

Description

technical field [0001] The invention belongs to the technical field of pesticide processing, and relates to an acaricide, in particular to a bitter horse bean acaricide and a preparation method thereof. Background technique [0002] Swainsonia salsula Taub (Swainsonia salsula Taub.) is a plant of the genus Swainsonia salsula Taub. It is also known as sheep urine bubble, horse skin bubble, red bitter bean, sheep follicle, urine bubble grass, sheep egg egg, bell dang grass, etc. It is a perennial herb.
