General use of 50% phoxim EC, 50% chlorinated pine EC, 40% acephate EC, 80% Trichlorfon Soluble powder each 1000 times, or 2.5% deltamethrin EC, 20% cyanopentan Emulsifiable Chrysanthemum emulsifiable concentrate, 2.5% Kantaverin Emulsion, 5% Fenvalerate (Laurel) Emulsion, 10% Cypermethrin Emulsion, etc. are each sprayed at 2000 times; or 1000 times as much as a microbial pesticide such as "HD-1" Liquid, spraying with 100 million spores of Bacillus sp. solution per ml.
