Pests and their control on Trachelospermum variegatum

Damage caused by moth larvae

Variegated Trachelospermum is sometimes damaged by moth larvae, which mainly occurs from June to September each year. You can kill them before they lay eggs and use pesticides in time, such as spraying 1000-2000 times diluted 5% cypermethrin emulsifiable concentrate or 2000 times diluted 1% avermectin emulsifiable concentrate, both of which should be done in the evening. Usually pay attention to keep the environment ventilated.

The harm of nematodes

For variegated ivy, nematodes are also a pest that must be prevented. When variegated ivy is infested with nematodes, it can be treated with drugs. Use 2000 times the solution of 40% chlorpyrifos emulsifiable concentrate to disinfect the soil and kill the nematodes. Prevention is the priority, combining prevention with treatment.

The damage caused by aphids

Aphids are a very common pest of variegated ivy. Aphids will suck the sap of variegated ivy in the young and tender parts of the variegated ivy, endangering the health of the variegated ivy. When aphids infest variegated ivy, you can use 2000~3000 times diluted 48% Lorsban emulsifiable concentrate or 1500 times diluted imidacloprid 25 wettable powder for prevention and control. Prevention should be the main approach, with treatment as a supplement, to prevent and control aphids rationally.

The harm of red spiders

Red spider mites are also a common pest of variegated ivy. When tiny red spider mites appear on variegated ivy, it indicates danger. When red spider mites occur, you can spray 1000~1500 times diluted 15-dacarbamate for prevention and control. Hot and humid weather can easily cause red spider mites. You can ventilate more and keep the air flowing.
