It has entered the rainy season, it is difficult to manage the exposed vegetables, especially the more summer watermelon, the current disease in watermelon production prone to diseases and anthrax. So remind melon farmers to focus on preventing these two diseases.
The disease of watermelon is also called Phytophthora, commonly known as "dead bug". It is a kind of soil fax fungus disease. It can occur in watermelon seedlings and adult plants, especially in the late stage of watermelon growth and high temperature and rainy conditions. The onset is rapid and severe; If the rainy season comes early, the rainfall is long, and the rainfall is heavy, the onset is early, the condition is heavy, and the loss is large. The peak incidence in the field is often immediately after the peak rainfall. The incidence of temperature limit is 5 ~ 37 °C.
Symptoms: The onset of the leaves, resulting in dark green water spots round or irregular shaped spots, rotten or boiled like hot water when the humidity is high, light brown spots when dry, easy to break. The basal part of the vine spreads and a spindle-shaped water-immersed dark green spot appears. The surrounding stalk is severely rotted and all of the diseased parts die. Onset of fruit, the formation of dark green round water-immersed depression spots, rapid expansion after the whole fruit, resulting in fruit rot, the smell of silage, dense white mycelium diseased surface.
Control methods: From the early stage of disease occurrence, use 50% methicone wettable powder 700 to 800 times liquid, 72.2% Precic water 800 times liquid, 64% antivirus WP 500 times, every 7 to 10 Spray once a day, even spray 3 to 4 times. If necessary, the above-mentioned liquid can also be used to irrigate the roots, and 0.4 to 0.5 liters per plant. If the spray and irrigation are performed at the same time, the effect is better.
Most of watermelon anthracnose is transmitted by seeds. If the disease is later infected, the disease department will again produce a large number of conidia, which will be transmitted through rainwater and irrigation to carry out secondary infections. At present, it is the high incidence of watermelon anthracnose that blooms in summer. The actual production shows that the terrain is low, the drainage is poor, nitrogen fertilizer is used too much, ventilation is poor, and the incidence of heavy land mass is even more severe.
Symptoms: Watermelon leaves are flooded with spots at the beginning of the disease. There are often yellow-brown halos in the periphery. The middle of the lesion is darkened and dark brown, sometimes with concentric ring patterns. It is easy to break when dry. Mature fruit infections are immersed in water-soaked brown spots, and sometimes there are cracks in the depressions. When the humidity is high, it is easily rotted.
Control methods: Use 25% Prochloraz EC 1000 times, 50% SPD WP and 1500 times to spray.
