What is papaya blight? How can papaya blight be prevented and controlled effectively? Please provide guidance on methodsThe harm caused by papaya blight:Papaya blight is commonly known as "water wound"; the pathogen is Phytophthora parasitica, which mainly damages papaya fruit and also damages the root system; it is prone to occur under high temperature and high humidity, especially after rain, and the pathogen can spread through airflow, rainwater, irrigation water, etc. It can cause the fruit to shrivel, turn brown-black, and drop, eventually becoming black mummified fruit.
Methods for preventing and controlling papaya blight:
1. Implement crop rotation; avoid choosing low-lying plots for planting; spray New High Lipid Film in a timely manner to preserve soil moisture and inhibit the reproduction of soil-borne pests and diseases.
2. During the rainy season, pay attention to timely aeration and drainage, and spray chemicals plus New High Lipid Film to prevent the occurrence of blight. At the same time, it can form a protective film to increase efficacy and prevent the pathogen from spreading through airflow and rainwater. For mechanical injuries during agricultural operations, promptly apply wound healing and antiseptic film to the wound to protect the wound tissue, promote healing and growth, and prevent pathogen invasion.
3. Quickly remove diseased plants and diseased fruits and burn or deeply bury them to reduce sources of the pathogen, and spray General Guardian for disinfection.
4. At the early stage of disease onset, spray 58% metalaxyl?mancozeb wettable powder at 600 times dilution, or 70% fosethyl?mancozeb wettable powder at 500 times dilution, 72% DuPont Curzate wettable powder at 600-700 times dilution, or 69% Anchor?mancozeb wettable powder at 900 times dilution.
