The material that the present invention is used is easy to be shaped to granule or pulvis, wherein contains the solid dilution, and the material used with the present invention mixes mutually.In these pharmaceutical formulations, contain approximate weight usually and be the present invention of 1～50% material.When these preparations physically with after last table soil mixes gently, the effect of its Pest Control is better.Described mixing is when plant seed being broadcast into soil, or before, or carry out afterwards.
Material of the present invention also can be used as a kind of immersion liquid and uses, and promptly the present invention's material is dissolved in the solvent of plant-less toxicity, or dilution, or in the suitable water, thereby form a kind of solution or dispersion liquid.The concentrate of the material that contains the present invention can water be diluted in such immersion liquid, and emulsifier is made, and to use organic solvent, dilutes for best as toluene.
The ratio that is suitable for being applied in the mobilization compound in the soil is 0.01～11 kilogram/hectare, is best with 0.1～5 kilogram/hectare, particularly 0.5～4 kilogram/hectare.
The present invention used 0,0-diethyl 0-(1,2,2,2 ,-tetrachloro ethyl) thiophosphate, available different, the conventional method preparation for preparing thiophosphate.One of them method is with phosphorus pentachloride acid treatment chloral, to obtain CCl
3CHCl O PCl
4Obtain intermediate product CCl again with hydrogen sulfide treatment
3CHCl OP(S) Cl
2Obtain ester required for the present invention with this dichloride of Ethanol Treatment.With in the reaction of Ethanol Treatment, can there be atent solvent to exist, but do not having under the situation of solvent, this step reaction also can be carried out satisfactorily.
Following example is used to explain the present invention.
The test of example 1. pumpkins 12 asterophyllite first
The compound of test is dissolved in acetone solvent, and fully mixes with dry soil.After the vestiges of solvent vapor away, add the also abundant mixing of entry and make the humidity of soil reach 9%.
