③ 800-1000 times for 25 percent дихлофос эмульсия, 600-1000 times for 80 percent crystal trichlorfon, {400-600 times for 25 percent dichlorvos, etc. The Dispensing Концентрация Must Be Different Accord to different worm bodies, different worm states, and worm ages. Чет если они есть оба взрослые, в целом the resistance is strong when the temperature is low, the resistance is weak when the temperature is high, and the resistance is weak when the temperature is weak when the temperature is first eclosion. Before and after overwintering, there is also a big difference in the resistance of stinkers. Before overwintering, the resistance was strong, and in the spring of the follow year, the resistance was значительно уменьшено.
