What pests are there in growing Angelica dahurica? How should they be controlled? Please advise.
The main pests of Angelica dahurica are the green peach aphid, the carrot willow aphid, Sapporo two-tailed aphid, the red-striped stink bug, the yellow swallowtail butterfly, the yellow-winged fennel moth, the sweet potato cryptic moth, the small green flower chafer, the Japanese beetle, and red spider mites. For the green peach aphid, carrot willow aphid, Sapporo two-tailed aphid, and red-striped stink bug, control can be done by spraying a 0.3% matrine botanical insecticide at 500--1000 times dilution or derris extract at 600 times dilution.
For the larvae of the yellow swallowtail butterfly, yellow-winged fennel moth, and sweet potato cryptic moth, spray Bt emulsion at 200-300 times dilution. For 2nd-3rd instar larvae, spray Qingchongjun (containing 10 billion bacteria per gram) at 300 times dilution for control. For young larvae, matrine botanical insecticide at 500-1000 times dilution can also be sprayed.
The adults of the small green flower chafer and Japanese beetle feed on flowers; adults can be caught by hand, or derris extract at 600 times dilution can be sprayed.
Red spider mite control: spray 0.3% matrine botanical insecticide at 500-1000 times dilution or 50% sulfur suspension concentrate at 300 times dilution.
