Harm of cilantro leaf blight:
Once the disease occurs, the condition spreads rapidly and the harm caused is relatively serious. It mainly harms the leaves; after the leaves are infected, they turn yellow-brown, and when humidity is high, the diseased parts rot; in severe cases, it infects downward along the leaf veins to the tender stems and then to the heart leaves, causing serious yield reduction, so this disease must be especially controlled.
Control methods for cilantro leaf blight:
1. For the control of cilantro leaf blight, preventive measures focusing on seed disinfection are used; the method is to soak the seeds in a 500-fold solution of "captan" or "carbendazim" for 10-15 minutes, rinse them clean, and then sow.
2. Strengthen the management of cilantro; when humidity is on the high side in the early stage of closing the greenhouse, pay attention to ventilating to remove moisture. If disease is found, spray promptly for control, using a 600-800-fold solution of carbendazim, a 600-fold solution of mancozeb, an 800-1000-fold solution of 70% thiophanate-methyl, or a 500-fold solution of chlorothalonil; mixing two or more of them gives a better effect.
