Embodiment Construction

[0032] The present invention will be further described below through examples and comparative examples, but the present invention is not limited to these examples.

[0033] The present invention provides composition examples 1-18, see Table 1-Table 6. As can be seen from Table 1-Table 6, the concentration range of monosultap in the composition microemulsion is 4%-20%.

[0034] The present invention also provides four groups of control experiments on the effects of using different concentrations of monosultap microemulsions and monosultap soluble powder aqueous solutions, see Table 7-Table 10. As can be seen from Table 7-Table 10, the monosultap microemulsion of the present invention is higher than monosultap in the drug holding capacity on rice and cabbage, the utilization rate of pesticides, and the control efficacy of diamondback moth and rice leaf roller Soluble powder aqueous solution. Table 1 Table 2 table 3 Table 4 table 5 Table 6

Abstract

The synergistic monosultap microemulsion for rice and cabbage is oil-in-water microemulsion comprising soluble monosultap powder; synergist diesel oil and 1-dodecyl azasuberyl-2-one; surfactant calcium dodecyl benzene sulfonate, alkylphenol formaldehyde ethoxylates, alkylphenol ethoxylates and polyethenoxy anhydrosorbitol monostearate; antifreezing agent glycol and diluent water in certain weight proportion. The pesticide liquid has surfactant concentration exceeding critical micelle concentration and surface tension smaller than surface tension of rice and cabbage. It is sprayed with sprayer to spread on the plant foliage resulting in high pest preventing and killing effect.

Description

(1) Technical field [0001] The invention relates to a microemulsion pesticide for controlling rice and cabbage pests, in particular to a synergistic insecticidal single microemulsion capable of wetting and spreading on the surface of rice leaves and cabbage leaves. (2) Background technology [0002] Monosultap (1-thiosulfonate-2-dimethylamino-3-thiosulfonate propane) is a nereistoxin insecticide independently developed and produced in my country. Its chemical structural formula is: [0003] The insecticide is poorly soluble in organic solvents and easily soluble in water. For a long time, soluble powders have been dissolved directly in water and sprayed on plants such as rice and cabbage. Since the medicinal liquid does not contain any surfactant, the surface tension of the medicinal liquid is greater than the critical surface tension of rice and cabbage leaves, the sprayed medicinal liquid cannot be wetted and spread on the surface of the plant leaves but rolls down, re...
