Chemical control (1) injection of 50% of young larvae fenitrothion EC 1000 times, or 50% dichlorvos EC 1000-1500 times, or dimethoate 40% EC, or EC malathion 800-1000 times, or 75% phoxim EC, or 50% of parathion EC 2000 times, or trichlorfon crystal 1000-1500 times, or 40% Isocarbophos emulsion, or 50% methamidophos emulsion 500 -1000 times, or carbaryl 25% wettable agent 1500 times, or 2.5% O, cyhalothrin, or 20% of the speed kill D EC 3000-5000 times, or 10% Cypermethrin EC, per hectare medication 150 to 300 ml, or the destruction of 20% of juvenile dirty rubber suspension 3 times agent 2000-3000. (2) people have been shoot in the moth larvae can be 50% monocrotophos EC, 10 EC or 40% Omethoate trunk injection times, or fenitrothion 50% EC, or EC 50% with phosphorus dibromide 40 times a smear to be harmful. |
