Under unfavorable growing conditions, radishes may develop physiological diseases leading to rot, resulting in poor quality and reluctance from merchants to purchase. So, what are the preventive measures for preventing radish rot? Let's find out together.
Reasons for Radish Rot
-
Excessive rainfall, failure to drain in time, causing root hypoxia and subsequent rot.
-
Unripe fertilizers causing root burns, facilitating the entry of pathogens and causing root rot.
-
Occurrence of bacterial soft rot or black rot diseases.
-
Continuous cropping or consecutive cultivation with cruciferous vegetables.
-
Early seeding.
Preventive Measures for Radish Rot
-
Selecting Suitable Land: Choose land that hasn't grown radishes for at least 3 years or any cruciferous vegetables like rape, cabbage, etc.
-
Timely Sowing: Sow seeds around the Beginning of Autumn festival.
-
Organic Fertilizer Application: Apply sufficient organic fertilizer. Radishes prefer organic fertilizers, and manure should be fully decomposed. Avoid using fresh manure to reduce the risk of rot. Deep plowing and leveling the land before planting are crucial to enhance soil permeability.
-
Raised Bed Planting: Proper watering, maintaining soil permeability, and regular hilling are essential. Avoid waterlogging and maintain consistent bed height through hilling to ensure adequate oxygen supply to the roots.
-
Drainage: Ensure timely drainage after rain and avoid excessive flooding.
-
Chemical Control: Apply appropriate pesticides like imidacloprid or pyrethroid if aphids are detected. For root rot caused by root maggots, use 50% dimethoate emulsion, 80% dichlorvos emulsion, or 90% crystal trichlorfon emulsion at the early stage of infestation.
Above are the preventive measures for preventing radish rot. Radish rot significantly affects its economic value, so farmers need to implement scientific prevention and control measures and invest sufficient effort in management to ensure high-quality and productive radish cultivation.
