What are the common pests of flowers and trees? Explained clearly in one article

Several common pests of flowers and trees:

Controlling scale insects and aphids: spray with 40% omethoate emulsifiable concentrate at 1000 to 2000 times dilution or 50% fenitrothion emulsifiable concentrate at 1000 times dilution.

Controlling scarab beetles: use black light traps to kill adults, hand-pick and kill adults, and spray 40% omethoate emulsifiable concentrate at 1000 times dilution or 90% trichlorfon original liquid at 800 times dilution.

Controlling longhorn beetles: hand-pick and kill adults, dip a cotton ball in dichlorvos liquid and insert it into the insect holes to poison the larvae, and coat the tree trunks with lime sulfur mixture to prevent adults from laying eggs.

Controlling powdery mildew: prune out diseased branches and leaves and burn them in a centralized manner; at the early stage of the disease, spray 50% carbendazim wettable powder at 800 to 1000 times dilution or 70% thiophanate-methyl wettable powder at 800 times dilution.

Controlling southern blight: ensure good ventilation and light, and strictly disinfect the potting soil; during the disease outbreak, drench the base of the plant and the surrounding soil with 50% thiophanate wettable powder at 500 times dilution or 50% carbendazim wettable powder at 500 times dilution.

Controlling damping-off: burn the diseased plants in a centralized manner, and at the early stage of the disease, drench the roots with 70% thiophanate-methyl wettable powder at 1000 times dilution.
