A Detailed Guide to the Prevention and Control of Pests and Diseases on Japanese Honeysuckle (Lonicera japonica)
Anthracnose occurs frequently in summer and can be controlled by drenching with a 500-1000 times dilution of wettable Dexon powder. For rust, spray a 200-250 times dilution of the technical-grade dithianon sodium (you may add 50-100 g of washing powder to 50 kg of the spray solution as a sticker). Insect pests include aphids, longhorn beetles and others; aphids can be sprayed with a 4000 times dilution of 10% imidacloprid, while longhorn beetles can be sprayed with a 500 times dilution of duomeike (methomyl). Note, however, that toxic pesticides must never be used on Japanese honeysuckle during the bud stage.
