Problems solved by technology

[0006] Chinese patent (application number CN2015100098343, application date January 9, 2015) reported that the patent applicant is Xihua University, the general formula is TDCA containing three nitrogen Heterocyclic 1,2,3-thiadiazole-5-carboxamidine compounds and their synthesis method (Formula 6), but there is no report on the use of such compounds as acaricides
On the other hand, farmers are used to continuous use of a single acaricide with good acaricidal effect, resulting in the resistance of mites for a long time and loss of use value

Abstract

The invention discloses application of a 1,2,3-thiadiazole-5-formamidine compound with three azacyclesas an acaricide, wherein the compound has a novel chemical structural formula of TDCA shown in the specification and is particularly applied to control of pest mites of fruit trees, vegetables, cotton, peanuts and other crops as well as ornamental plants.

Description

technical field [0001] The invention relates to a class of novel acaricide pesticides, in particular to the use of N-trisubstituted-1,2,3-thiadiazole-5-carboxamidine compounds with novel chemical structures as acaricides. Background technique [0002] Amidines have a wide range of applications in medicine, and can be used as drugs for treating diabetes, cardiovascular diseases, anti-inflammatory drugs, anthelmintics and diuretics. For example, the cyclic amidine compound described in Formula 1 has a vasodilator effect and is used for the treatment of hypertension. The aryl-substituted amidine compound containing multiple iodines described in Formula 2 has higher selectivity to tuberculosis fungus, and its cholepicamidine sodium is an oral cholecystectomy and cholangiography drug. Low toxicity, few side effects, safe for patients. Compared with traditional medicines, the angiography is quick, the patient does not need to fast, and the imaging effect is good. In addition, s...
