Thrips pose a serious threat, and crops often experience the following situations:

◆ The tender leaves and shoots of crops are curled, withered, thinned, and have white spots;

◆ There are gray white or gray brown stripes on both sides of the midrib of the leaf, and the epidermis is gray brown;

◆ There are yellow and gray spots on the back of the leaves;

◆ The flowers are covered with dense yellow and black small insects;

◆ There are scars on the fruit, deformed fruit may appear in the later stage, and even fruit drop may occur

Why is the prevention and control effect of thrips getting worse and worse?

1. The thrips family is large, has a wide range of hosts, and has strong reproductive ability, which can cause harm for a long time. Due to their habit of sleeping around the clock, it increases the difficulty of prevention and control!

2. In production, plants damaged by thrips often exhibit the phenomenon of curling and wrinkling of the top leaves, which is easily confused with vegetable virus diseases, leading to misdiagnosis and delaying the disease.

3. Some pesticides only kill adults but not eggs, resulting in the continuous growth of adults after the eggs hatch. So this practice of 'cutting grass without removing roots, controlling insects without killing eggs' gradually leads to resistance in the breeding process of pests!

4. Increased drug resistance: Due to the short reproductive cycle of thrips, the change in drug resistance is particularly rapid.
