What Pesticides Work Best to Control Aphids on Fruit Trees

Fruit trees cannot avoid being attacked by pests during their growth, and aphids are one of the pests that affect fruit trees. When aphids appear on fruit trees, how should we control them?

1. What pesticides to use for aphids on fruit trees

For aphids on fruit trees, you can use pesticides such as imidacloprid, thiamethoxam, acetamiprid and pymetrozine, or combine chlorpyrifos and lambda-cyhalothrin with systemic pesticides. You can also use spirotetramat and sulfoxaflor in a compound formulation.

These insecticides enter the insect body through four modes - contact action, stomach action, fumigation and systemic action - causing the aphids to be poisoned and die.

2. Other ways to control aphids on fruit trees

1. Plant-based control: generally, plants are crushed or boiled in water, then filtered and sprayed. Such plants mainly include: tobacco leaves, peach leaves, garlic, loofah, castor bean leaves, Chinese chives, etc.

2. Physical control: aphids avoid silver-gray, so strips or boards of this color can be hung in the orchard; aphids are attracted to yellow, so sticky yellow boards can be coated with adhesive to trap and kill winged aphids; insect sex pheromones can also be used to lure aphids into water to drown.

3. Natural enemy control: aphids have many natural enemies, such as ladybugs, hoverflies, spiders, parasitic wasps, etc. After screening these insects, they can be introduced, bred or released to strengthen pest management in the orchard.

4. Remove eggs. Weeds, dead branches and fallen leaves in the orchard should be cleaned up promptly to reduce aphid eggs.

The above are several control methods for aphids on fruit trees. We hope they are helpful to friends who are struggling with pest problems.
