Egg mass; when a small amount of aphids appear on spring flowers, they can be washed away directly with water.
2, seed coating agent to control aphids
The agent can protect the seed from pests and diseases, and seed dressing with 48% chlorpyrifos EC at a seed weight of 0.3% or 40% phoxim at a seed rate of 0.2%. After 4 to 6 hours, it can be sprinkled into the field to effectively control cockroaches. Underground pests such as cockroaches and golden worms can also control aphids, red spiders, and gray planthoppers at the seedling stage.
3, using the trend to trap aphids
(1) A golden-colored plastic film is placed between the rows of plants, about 0.33 × 2 m in size, coated with a layer of petrolatum or engine oil, fixed at a height of 0.5 m above the ground, and can catch a large number of winged aphids.
(2) Spread silver-gray mulch or hanging plastic strips in the garden to avoid flying mites.
4, physical methods to eliminate mites
(1) Take the shredded pepper with a strong spicy taste, boil it in a pot at a ratio of 1:20 for 15 minutes, then spray it after cooling, and spray it at a high temperature.
(2) The plant ash is soaked in water at a ratio of 1:5 for 24 hours, then filtered out, sprayed with leaves, sprayed once every 7~8 days, and sprayed three times, which can effectively control pests such as aphids and cabbage caterpillars.
(3) Dissolve the salt in a ratio of 1:1, and mix the lime in a ratio of 1:4. After filtering, the two liquids are thoroughly stirred, and diluted at a ratio of 1:4 during spraying.
(4) When there are sporadic small area aphids, you can soak 4~5 cigarette butts and add a small amount of soap to spray the plants for one week. If the area is sick, you need to soak the leaves in a ratio of 1:10. Spray after filtration.

(2) Before the flowering, after the flowering, use 1.8% avermectin 3500 times solution, or 480 g / liter chlorpyrifos emulsifiable oil 1000 times solution; when large area insects, use 50% chlorpyrifos emulsion 1000 times solution, 2.5 % deltamethrin emulsion 3000 times solution, or 40% imidacloprid water solvent 1500 ~ 2000 times solution, etc.
It is recommended to use low-toxic, high-efficiency, low-residue agents, and a variety of drugs to rotate to prevent aphid resistance; spray spray is recommended, the leaf dripping is appropriate, 7 days after the spray.
