(1) Practice crop rotation with non-cruciferous crops. Yellow stripe flea beetles only eat vegetable core, cabbage, kale, mustard and other cruciferous plants, if the flea beetles occur before the peak of an extensive planting of non-cruciferous vegetables, such as endive, dodgers, green onions, garlic, water spinach, spinach, corns, etc., flea beetles no food will starve to death. Can achieve "without war and give up the army".

(2) in the seedling period to prevent adult insects to move in to lay eggs, available dichlorvos, a good clear, malathion spray.

It is best to sprinkle chlorpyrifos granules, such as Baosha, Jaspen, etc., to kill the flea beetle larvae in the roots during the seedling stage.

(3) In the middle seedling stage, you can use chlorpyrifos (such as Nongst) 2000 times plus phoxim 1500 times spray to kill.

(4) Use low-toxicity imidacloprid (e.g. Gomang or Gomang) 2000-3000 times, or rotenone plus a small amount of fipronil (e.g. Ruijinte) to spray at the large seedling stage.

Please remember, to kill flea beetles must prevent the larvae in the root of a large number of breeding, the combination of foliar and soil control in order to change the current passive state. More important is the correct selection of drugs and control the use of dosage to ensure that the product is pollution-free.
