Aphid control can refer to the following methods: chemical control can be sprayed with some pesticides, which can kill a large number of aphids, but some can still survive, due to the rapid reproduction and large number of aphids. The surviving aphids soon formed a large number of populations. Therefore, the use of medicine should be determined according to the pest situation. If aphids first fly to some sprouts of trees and flowers to breed harm, and when the number of insects is small, the sprouts can be cut off at any time, the newborn aphids can be eliminated, and the buds, tender leaves and leaf backs can also be washed with clean water. When there are a large number of insects and leaf curling has occurred, it can be sprayed with 50% Zaijing EC 1000 × 1500 times or Lesbon 1500 times or 20% fenpropathrin EC 2000 times or pyridine 5000 × 10000 times.

It can also be combined with pruning to cut off the severely damaged branches with rolled leaves to remove aphids. In addition, there will be cigarette butts, Gleditsia, pepper and other water soaked after spraying, can also control aphids.
