Distribution and Harm of Green萝 Soft Rot Disease
It occurs in various cultivation and introduction areas. It causes leaf and stem rot, and the upper part wilts and dies.
Symptoms of Green萝 Soft Rot Disease
It harms the green tender stems and petioles of Green萝. Initially, the disease causes blurred, water-soaked spots on the green tender stems or petioles, which then rapidly expand upwards, downwards, and laterally. Subsequently, the inner tissues of the tender stems and petioles begin to soften and rot, emitting a foul odor. When the lesion circles the petiole, the upper part will break off and turn yellow.
Incidence Pattern of Green萝 Soft Rot Disease
The pathogen can grow within a temperature range of 4-39°C, with the optimal temperature being 25-30°C. The lethal temperature is 50°C for 10 minutes. It is prone to occur and spread in environments that are airtight, stuffy, and humid.
Prevention and Control Measures for Green萝 Soft Rot Disease
▲ Ensure proper ventilation for the placement of Green萝, and water only when the soil is dry, watering thoroughly each time, without frequent watering. Water from the edge of the pot. Avoid watering from above, especially after the disease is detected, and never spray water from above.
▲ Immediately cut off the diseased leaves, including some healthy parts that are not affected. When the tender stems are infected, cut off the tender stems 2 cm above and below the lesion that do not show symptoms, and the healthy upper tender stems can still be used for propagation.
▲ Spray chemicals for prevention and control. In the early stage of the disease, you can choose to spray 50%琥胶肥酸铜 wettable powder 500 times liquid, 77%可杀得微粒 wettable powder 500 times liquid, 14%络氨铜 water-based liquid 300 times, 72%农用链霉素 soluble powder 400 times liquid, or new植霉素 4000 times liquid.
