Improve the ventilation conditions and reduce the temperature; often spray water around the plants to increase the air humidity. 4. Chemical control: available 20% dicofol 500-1000 times, 50% bromo antimony emulsion 2500 times, 40% omethoate 1000 times, 15% zeoli EC 2000 times spray every 7-10 days Spray once, spray a total of 3-4 times. Due to the strong drug resistance of red spider, care should be taken to alternate use of the drug;
