Dilution Ratio
Adopt different dilution ratios according to different usage scenarios. For conventional sanitary pest control indoors, dilute 50% DDVP emulsifiable concentrate at 500–800 times. For agricultural pest control on crops, dilute at 1000–1500 times (10 mL of original pesticide mixed with 10–15 kg of clean water). Prepare the liquid medicine immediately before use to avoid efficacy reduction.
