How to control black locust aphids? Master these methods for good results
Control methods for black locust aphids: 1. Protect natural enemies such as ladybugs, hoverflies, green lacewings and aphid parasitoid wasps. 2. Strengthen pest monitoring and forecasting. When the number of winged aphids suddenly increases and the rate of aphid-infested plants reaches 20% to 30%, spray pesticide promptly. If the ratio of ladybugs to aphids reaches 1 to 100, and the aphid population shows a declining trend, stop spraying pesticide for control and protect natural enemies. 3. During the peak outbreak period, spray 50% pirimicarb wettable powder at 1500 times dilution, 10% imidacloprid wettable powder at 1500 times dilution, or spray EB-82 aphid-killing fungus at 300 times dilution
