use:

Thiazolidinone acaricides. This product is broad-spectrum and has good effects on young nymphs and eggs of various spider mites, but has poor effect on adult mites. After treatment with the agent, the eggs laid by female mites cannot hatch. It mainly has contact killing effect, has good permeability to plant tissues, and has no systemic effect. The effect of the drug is slow, but the residual effect can be as long as more than 1 month. Safe for crops, feeding mites and beneficial insects. For example, to control apple red spider mites, when there are an average of 3 to 4 mites per leaf during the peak period of young nymphal mites, use 5% emulsifiable concentrate or 5% wettable powder 1500 to 2000 times liquid spray. Stop using 7 days before harvest.

production method:

It is obtained by condensing trans-5-(4-chlorophenyl)-4-methyl-2-oxothiazolidinone and cyclohexyl isocyanate as raw materials. 20g of trans 5-(4-chlorophenyl)-4-methyl-2-oxothiazolidinone and 11.9g of cyclohexyl isocyanate were added to benzene, and the reaction was stirred at room temperature. After post-treatment, 30.7g of thiazolidinone was obtained ketone. Preparation of trans-5-(4-chlorophenyl)-4-methyl-2-oxothiazolidinone: Dissolve trans-2-amino-1-p-chlorophenylpropanol in an organic solvent with an equimolar amount The sulfuric acid is condensed and dehydrated to generate trans-sulfate ester, and then reacts with carbon oxysulfide under alkaline conditions to generate thiocarbamic acid derivatives. At the same time, the intramolecular sulfur atom attacks the carbon on the phenyl group to generate p-, 5- trans-thiazolidinone. Formulated as 10% emulsifiable concentrate, 10% or 50% wettable powder.
