bacterial disease causes watersoaked lesions on leaves stems and pods These lesions eventually turn brown and necrotic The bacteria spread through splashing water wind and infected seeds Root Rot various pathogens Several soilborne fungi and oomycetes can cause root rot leading to wilting yellowing and stunted growth Poor drainage and excessively wet soil contribute significantly to root rot problems Phytophthora and Rhizoctonia species are 2 frequent culprits in Florida Virus Diseases various viruses Viral diseases transmitted by aphids or other vectors can cause mosaic patterns on

resistance to common diseases Crop Rotation Rotate your crops annually Avoid planting beans in the same location for consecutive years to reduce the buildup of soilborne pathogens responsible for root rot and other diseases Sanitation Remove and destroy infected plant debris at the end of the growing season This prevents the overwintering of pathogens and reduces the inoculum for the next growing season Proper disposal not composting is essential Proper Irrigation Avoid overhead irrigation which spreads fungal spores Use drip irrigation or soaker hoses to deliver water directly to the roots minimizing leaf wetness Ensure good soil drainage to prevent waterlogging Soil Health Maintain healthy soil through organic matter amendment Healthy soil supports stronger plants better equipped to resist diseases Consider soil testing to determine nutrient deficiencies and adjust accordingly 2 Disease Management Techniques Fungicides For fungal diseases like anthracnose and downy mildew appropriate fungicides can be effective Consult your local agricultural extension office or a certified crop consultant for recommendations on suitable fungicides registered for use on bush lima beans
