Banana thrip and odoiporus longicollis oliver prevention and control method

The invention discloses a banana thrip and odoiporus longicollis oliver prevention and control method. According to banana thrip prevention and control, during the squaring stage of banana plants, 70% imidacloprid water dispersible granule 200-fold liquid or 22.4% spirotetramat suspending agent 200-fold liquid is selected, a back barrel type special pesticide application device is used for injecting liquid pesticide into banana cauloids, and 20 ml of the liquid pesticide is injected into each banana plant. According to odoiporus longicollis oliver prevention and control, when odoiporus longicollis oliver causes harm, 48% chlorpyrifos missible oil 200-fold liquid is selected, the back barrel type special pesticide application device is used for injecting the liquid pesticide into the banana cauloids, and 20 ml of the liquid pesticide is injected into each banana plant. The back barrel type special pesticide application device is formed by a back barrel, a continuous drencher, a soft tube and an injection needle tube. The method has the advantages that the pesticide application amount is saved, the purposes of reducing the pesticide amount and ensuring the prevention effect are achieved simultaneously, pollution to the environment is reduced, pesticide application labor intensity is reduced, labor cost is saved, operation is convenient, pesticide application is free from limitation of weather conditions, and toxicity of the applied pesticide is reduced.
