How to get rid of aphids on sunflowers?

(1) When the number of potted flowers is small and aphids appear sporadically, you can gently brush them off with a brush dipped in water or wash the leaves with water to make them die. For potted plants with small and expensive flowers, you can light a cigarette, turn it upside down slightly, let the cigarette smoke with the leaves and young leaves of aphids, and the aphids will roll down one by one.

(2) When aphids occur in large quantities, it is necessary to spray chemicals in time for prevention and control. Besides dimethoate, dichlorvos and other chemical pesticides, plant pesticides such as tobacco limewater, pyrethrum and derris powder can also be used.

③ Protect and utilize natural enemies. The main natural enemies of aphids are ladybugs, ladybugs, syrphids and lacewings. These natural enemies play an important role in inhibiting the occurrence and harm of aphids.
