Bacterial Brown Spot (Beans)

Giant Pumpkins


Brown Spot (Beans)


Warm temperatures, in the 80°-90°F range, and wet weather

favor infection. The disease first shows up as yellow

flecks on the leaves, which later turn dark brown. Individual

spots are usually irregular in shape and remain fairly

small, surrounded by a narrow yellow margin, but lacking

a wide yellow halo.

Solution: Plant

disease-free seed, rotate crops, burn infected plant

tissues, and clean contaminated equipment. Avoid working

with plants when they are wet, as bacteria are easily

transmitted in films of water. To prevent infection,

or reduce its spread, apply Soap-Shield® Fungicidal Soap

at 7-10 day intervals. Following heavy rain, or when

the amount of disease is increasing rapidly, apply every

7 days, or even more frequently, at the highest recommended
