(1) A method was developed to determine residue of acephate and methamidophos in rape plants by GC/MS.

(2) Acephate was first evaluated in 1976, with further reviews of residue matters in 1979, 1981, 1984 and 1990.

(3) Acephate is a broad-spectrum pesticide within the suction, but also has low toxicity and high efficiency characteristics, is highly toxic pesticide methamidophos and other alternative ideal species.

(4) An acephate 50% WG was formulated using 98% acephate technical with diatomaceous earth as the carrier. Sentencedict.com

(5) Catalytic acetylation of methamidophos for the production of acephate in batch stirred tank by using ion exchange resin was presented.

(6) Acephate is on sale principally in the form of crystal in national and international markets.

(7) The acephate granule can enwrap the effective component acephate in the middle of the granule, which can prevent effective component from decomposing with good solubleness and no flying-dust.

(8) As the synthesis technology of acephate is fairly mature, so how to improve and optimize the separation and purification technology is becoming a key problem hurry to be resolved.

(9) According to practical requirements, the invention also can add pesticide for controlling plant graft pests, such as acephate, SW biological pesticide and disease preventer.

(10) At high and recommended concentration, the mortality of Ss, X-7 and Sc-All caused by acephate were 21% and 9.5%, 13% and 5.5%, 5.5% and 2%, respectively.

(11) Occupational epidemiological investigation in field and animal experiments were performed to study the toxicity of acephate.

(12) The method is also suitable for the analysis of EC and WP (emulsion and powder) of acephate.

(13) Conclusion: The effective ingredients of the gel bait were acephate and PH, 60-38 and the efficacy reaches Grade A of Standard for Hygienic Insecticides .
