Embodiment Construction

[0009] The following is detailed in conjunction with the examples, but not as a limitation to the present invention

[0010]

[0011] The above-mentioned rotenone content is calculated and formulated from the original rotenone medicine. The content of rotenone in the original rotenone medicine can be 30-97.25%, preferably 35-75%. The dosage is small and the quality is easy to guarantee. Other processes are the same as the above (omitted).

[0012] The following are the results of physical and chemical tests of 3.5% hypertonic rotenone EC:

Abstract

A hypertonic emulsified rotenone oil as agricultural chemical is prepared through such technological steps as adding raw rotenone (1-5 portions) to reactor, adding CT-901 penetrant (10-14 portions) and xylene (68-69 portions), raising temp to 50-60 deg.C, stirring, adding NPE-90 penetrating aid (2.5-3.5 portions) and 0208 anionic surfactant (8-10 portions) and stirring. Its advantages are high effect, no residual damage, quickly taking its effect, not generating resistance easily for pests and broad spectrum, especially preventing insect pest such as bollworm, red spider.

Description

Technical field [0001] The invention relates to the technical field of pesticides. Background technique [0002] The extensive use of chemical pesticides for a long time has played an important role in controlling pests, but it has posed a serious threat to human health. The environment is polluted to varying degrees, and the "sweeping" chemical pesticides have made the ecological balance out of control. A research report published by the National Academy of Sciences and other organizations pointed out: The pesticide residues in food currently exceed the standard, which is 100-500 times the normal value of the safe capacity accepted by children. Children are suffering from cancer and neurotoxicity. In addition, fruit trees and vegetables use the largest amount of pesticides in crops. Among them, the use of vegetables accounts for about 28% of the world's pesticide market sales. The highly toxic pesticide methamidophos has the highest detection rate, accounting for 71.3 of the tot...
