1. Which medicine is most effective?1. Rice seedling stage: If the rice seedlings are infected by thrips, it is recommended to use thiamethoxam varieties. Specifically, you can choose Bairui 35% thiamethoxam suspension seed dressing agent. After diluting, spray it on the rice leaves. Pay attention to spray both sides to achieve the effect. 2. Vegetables: If cultivated vegetables are infected with thrips, 25% thiamethoxam water-dispersible granules can be used for root irrigation at a concentration of 3000-5000 times. This will not only reduce viral diseases, but also reduce the damage caused by other underground pests. 3. Tobacco: If tobacco crops are infected with thrips, you can use 1000 times of 25% imidacloprid or 3000-5000 times of 25% thiamethoxam. In addition, to prevent the problem in advance, you can use drugs to irrigate the roots when transplanting. 4. Fruit trees: Mango is the most seriously damaged among fruit trees. You can spray it with 25% thiamethoxam. Note that you need to increase the amount used. You can spray it 800 times. It should also be mixed with avermectin in a barrel for use. 2. How to prevent and treatIn addition to spraying pesticides, thrips must also be managed more effectively. Usually, weeds in the fields should be removed regularly to reduce the source of insects. We must also strengthen the management of fertilizer and water to promote vigorous growth of crops and plants, thereby improving their disease resistance. In addition, physical control methods can also be used. Taking advantage of its tendency to turn blue, blue sticky boards can be set up to lure and kill adult insects. |
