赤霉素A_(4+7)水剂的稳定性研究

Study on the Stability about GA_(4+7) Aqueous Solutions

当温度超过50℃时,赤霉素A4+7(GA4+7)水溶液,容易分解而失去活性。研究表明:加入适量的农药助剂M,可以明显提高GA4+7水剂的稳定性,使其热贮分解率在5%以下,达到农药制剂热贮稳定性的要求。

GA4＋7aqueous solution is easily decomposed to lose activity at the temperature over 50℃.The research results indicate that the stability of GA4＋7 AS could be improved obviously with calculated pesticide adjuvants M,which could make decomposition rate of the thermal storage below 5%.Thereby,the thermal stability about pesticide preparation of GA4＋7 met the requirement.
