When scale insects harm orchids, what methods are used to kill the pests?
Use baijiu mixed with water at a ratio of 1:2 to drench the surface layer of the potting soil. I Use food vinegar to wipe the affected stems and leaves. Use diesel, laundry detergent, and water at a ratio of 10:0.6:6 to make a stock solution, then dilute it with water to a 30% oil content and spray the pesticide solution.
