Latest Control Measures and Precautions for Strawberry Aphids Explained in Detail

The market demand for strawberries is growing greater and greater now, and the number of people growing strawberries is also increasing year by year, while aphids are unavoidable during strawberry production. So how should strawberry aphids be controlled? And what should be noted? Follow the editor to learn about it together.

I. Control Measures

1. Agricultural control

After aphid damage occurs, old leaves and diseased leaves should be removed in time, and surrounding weeds should be cleared in time, so as to avoid giving aphids the possibility of further spread.

2. Physical control

Insect-proof nets should be set up in ventilated places in time, and the yellow-tropism of aphids can also be used by setting up yellow sticky boards inside the greenhouse to trap and kill them. Generally, 10-20 boards are used per greenhouse, hung at a height slightly 10-20 cm above the strawberry plants, to trap and kill winged aphids. Note that they need to be replaced regularly.

3. Biological control

In the early stage of aphid occurrence, the natural enemies of aphids can be used for control. The common natural enemies of aphids are mainly ladybugs; 100 cards (20 eggs per card) can be released per mu to kill aphids. At the same time, attention should also be paid to protecting natural enemies such as green lacewings, hoverflies, and aphid parasitoid wasps to ensure a good control effect.

4. Chemical control

Pesticides such as thiamethoxam, acetamiprid, and abamectin emulsifiable concentrate can be sprayed for control, but attention should be paid to rotating the pesticides to avoid resistance. At the same time, when spraying, avoid the strawberry flowering period as much as possible to avoid phytotoxicity, and when applying the pesticide, the bees should be moved out of the greenhouse.

II. Precautions

1. Aphids are relatively small and mainly gather on the back of leaves, so when spraying, spray thoroughly and evenly.

2. Pay attention to alternating the use of pesticides to avoid resistance; for example, pymetrozine, thiacloprid, spirotetramat, Spinetoram, etc. can be chosen.

3. Aphids most easily spread viral diseases, so they can be controlled together with moroxydine hydrochloride, amino-oligosaccharin, fungal polysaccharide protein, etc.
