Parsley leaf blight

Once the onset of the disease is rapidly spreading, the resulting harm is more serious. The main harm to the leaves is when the leaves become yellowish-brown after they become sick. When the humidity is high, the diseased parts are rotted. The severe infections along the veins invade the tender stems to the heart and leaves, resulting in a severe reduction in yield. Therefore, this disease must be specifically controlled. We took preventive measures based on seed disinfection. The method was to soak seeds for 10-15 minutes with 500 times solution of "Coctam" or "Carbendazim", and rinse after sowing. The second is to strengthen management, in the early period of high humidity in the buckle shed should pay attention to venting moisture, found that the disease should be timely spraying control, with carbendazim 600-800 times solution, mancozeb 600 times solution, 70% thiol Bujin 800-1000 times, chlorothalonil 500 times, more than two kinds of mixed use better.
