Several common pests on flowers and trees

Several common flower and tree pests:

Control shell insects and aphids: spray with 1000 to 2000 times of omethoate EC or 1000 times of fenitrothion EC.

Control of beetles: use black light to trap and kill adults, spray 1000 times of omethoate EC or 1000 times of trichlorfon.

Control longicorn beetles: kill adults artificially, use cotton balls to dip dichlorvos solution into the wormhole to kill larvae, and spread stone sulfur mixture on the tree trunk to prevent adults from spawning.

Prevention and control of powdery mildew: cut off diseased branches and leaves and burn them, spray 50% carbendazim wettable powder 800 to 1000 times or use 70% methyl thiophanate wettable powder 800 times to kill.

Prevention and control of white silk disease: pay attention to ventilation and light transmission, basin soil should be strictly disinfected, and 500 times of 50% topiramate wettable powder or 50% carbendazim wettable powder should be used to irrigate the base of the plant and the surrounding soil during the onset of the disease.

Prevention and control of blight: burn the diseased plants centrally and irrigate the roots with 1000 times of methyl topiramate wettable powder at the initial stage of the disease.
