Every condition CropGuard knows how to spot

Dark, olive-green to black spots with a velvety texture appear on leaves and fruit, often causing early leaf drop in wet seasons.

Bright orange-yellow spots form on upper leaf surfaces, sometimes with small raised structures on the underside.

Small, cinnamon-brown pustules scattered across both leaf surfaces, most visible in cooler, humid conditions.

Rectangular tan-to-gray lesions run parallel to leaf veins, expanding to merge and kill large sections of leaf tissue.

Brown spots with concentric target-like rings develop on older, lower leaves first, eventually causing yellowing and drop.

Water-soaked, gray-green lesions spread rapidly across leaves and stems, often with a white fuzzy growth in humid weather.

Dark, irregular lesions on leaves and stems can spread to tubers, causing rot both in the field and in storage.

Dark brown spots with concentric rings appear first on older foliage, weakening the plant over the growing season.

Circular tan lesions with dark borders appear on leaves, while infected berries shrivel into hard black "mummies."

Irregular reddish-brown patches spread across leaf surfaces, occasionally merging into larger dead zones.

Small, water-soaked spots turn dark and scabby on leaves and fruit, often with a yellow halo around each lesion.

Small purple spots merge into larger scorched-looking patches, giving older leaves a dry, reddish-brown appearance.

Small angular lesions appear on leaves and can pit the surface of fruit, sometimes causing premature leaf drop.

A powdery white coating appears on young leaves and shoots, sometimes curling new growth as the season progresses.
