| The formulation of 30% Chlorfluazuron窑Chlorfenapyr SC was optimized with main adjuvants like wettingdispersing
agent, thicking agent, anti -freeze agent etc, the optimum composition consisted of Chlorfluazuron 26% ,
chlorfenapyr 4%, dispersing agent 4.0%, emulsifier 1.0%, thicking agent 1.7%, anti-freeze agent 4.0%, defoamer 0.4%, up
to 100% by water. The formulation was developed with the method of wet grinding. The results showed that the formulation
had good dispersion property in water, the suspension rate exceeded 90%, and its physical and chemical properties were
not changed significantly when it was stored under cold and heating conditions respectively |
