[0015] 1. Experimental method

[0016] (1) Preparation of racemic anisodamine hydrochloride (prepared according to the method in the embodiment)

[0017] Take 50 mL of commercially available racemic anisodamine hydrochloride injection (produced by Tianjin Pharmaceutical Jiaozuo Co., Ltd., specification: 1 mL×10 mg×10 sticks), add 40 mL of xylene to dissolve, and add Span 8010 mL and Tween 8010 mL to promote hydrochloric acid digestion. For the dissolving of anisodamine, conventional auxiliary materials are added according to a conventional process to make a spray.

[0018] (2) Determination of indoor biological activity

[0019] Slide immersion method: Use double-sided adhesive tape to stick healthy and lively adult female mites of the same size to one end of the slide downwards, and remove dead or injured individuals under a dissecting microscope to ensure that the number of spider mites per slide is Take out 30 heads after soaking in the liquid medicine for 5 seconds, and ...

Abstract

The invention discloses a novel plant acaridal application of racanisodamine hydrochloride and especially to application of racanisodamine hydrochloride in killing carmine spider mite. A method for preparation of an acaricide from racanisodamine hydrochloride comprises the following steps: adding 25 to 75 volume parts of commercially available racanisodamine hydrochloride injection into 20 to 60 volume parts of a solvent for dissolving, adding 5 to 15 volume parts of a solubilizer or / and 5 to 15 volume parts of an emulsifier to promote dissolving of racanisodamine hydrochloride and adding conventional adjuvants to prepare a spraying agent, missible oil, a suspending agent or pulvis according to a conventional process. The invention provides a novel harmonious pesticide which has good compatibility with the environment and is safe to mammals, which is of profound significance to long-term development of ecology, health of mankind and comprehensive control of pest mites.

Description

technical field [0001] The invention relates to a new application of racemic anisodamine hydrochloride, in particular to a new application of racemic anisodamine hydrochloride for plant acaricide. Background technique [0002] Raceanisodamine Hydrochloride is the hydrochloride salt of the compound (±)-6-hydroxy-1H,5H-tropane-3-ol tropic acid ester. Molecular formula: C 17 h 23 NO 4 HCl 4 , molecular weight: 341.84. Commonly used in peripheral anti-M choline receptors, can relieve smooth muscle spasm caused by acetylcholine, can also relieve microvascular spasm, and improve microcirculation. It has a relaxing effect on the smooth muscle of the gastrointestinal tract and inhibits its peristalsis, and its effect is slightly weaker than that of atropine. Its inhibitory effect on the secretion of digestive tract glands is 1 / 10 of that of atropine. The effect of inhibiting salivary gland secretion and dilating pupils is weak, which is 1 / 20 to 1 / 10 of that of atropine. Becau...
