Many insects will appear on Begonia flowers, and different insects use different drugs, so we should first determine which kind of pests are on the plant, and then spray the drugs

2. Gypsy moth: it mostly appears on the back of leaves. After discovery, it should be sprayed with pyrethroid insecticides or phoxim EC

3. Starscream: after the plant is invaded by Starscream, some small spots will appear on its leaves. You can buy benzotin emulsion or triazole tin wettable powder for spraying

4. Longicorn beetle: This is also one of the very common pests. If it is found, it should be used immediately. It can be killed by cypermethrin contact microencapsulation. Dichlorvos can be used for prevention and control if it appears in the trunk
