A complete guide to common sunflower pests

Meadow borer

When there are fewer pests, you can scrape them off directly. It would be better if you have a sharp eye so that you can find the pests when they are eggs and remove them in time.

When the disease breaks out, you can spray cypermethrin emulsifiable concentrate or cypermethrin emulsifiable concentrate, dilute it with water and then spray it.

If the seedlings are sick, you can choose dichlorvos powder or insecticide powder and sprinkle it directly on the bottom of the seedlings and the soil, 10 to 15 grams per plant.

Sunflower leafminer

Leaf miners are quite stubborn, so you can spray them with dichlorvos powder or cypermethrin powder once every 2 to 3 days until they are completely eliminated.

Of course, you can also use the spray method to dilute the dichlorvos emulsion into a 1000-fold solution and spray it around the plants and on the leaves.

Black Velvet Scarab Beetle

Does it sound familiar to you? This is a very common pest at this time. When the plant has dead leaves and rotten stems, this pest will come to follow the scent. You can use cypermethrin or chlorpyrifos powder to spray the soil surface, and make sure to spread it evenly.

Spray with 50% methyl thiophanate emulsifiable concentrate solution. If there are many insects, you can spray it directly on the pests.

Select elm leaves with leaves, soak them in a long-acting phosphorus solution for 10 hours, and then insert them next to the sunflowers at 2 pm, 2 to 3 leaves per plant. Naturally, the insects dare not come near.

Mongolian gray weevil

The simplest method is to spray a solution of DDT.

Make poisonous soil. Mix methyl 1605 powder with wet soil and sprinkle it around the plants. Pests will be poisoned to death when they get close.

Sand diving

Spray with 500 times solution of methyl parathion emulsifiable concentrate. Be sure to spray evenly and also spray the back of the leaves.

Sprinkle insecticide powder on the soil surface, 10-15g per plant.
