Common problems
Start from what you can see on the plant.
Pests and diseases (13)
Problems recorded for this plant, most serious first.
Aphids
MajorPest
Small green or black insects cluster on shoot tips and leaf undersides, crinkling the leaves and stopping growth. The honeydew they excrete supports sooty mold that blackens the foliage.
Spider Mites
MajorPest
Fine white stippling spreads across the upper leaf surface, and the leaf eventually whitens and dies back. In heavy infestations fine webbing appears on leaf undersides and shoot tips.
White Rust
CommonDisease
Creamy white slightly raised irregular pustules form on the leaf underside and burst through the skin releasing white powder. The upper surface turns pale yellow and heavy infection ruins appearance and market value.
Fusarium Wilt of Cucurbits
CommonDisease
Part of the vine wilts during the day and eventually the whole plant dies. The stem splits lengthwise near the soil and exudes gum, and the vascular tissue is browned when cut.
Damping-off
CommonDisease
The stem pinches in at soil level, turning water-soaked to brown and thin, and the seedling topples over. Infection before emergence makes the stand uneven with missing plants.
Root-knot Nematode
Pest
The plant wilts in the daytime and does not recover with feeding or watering. Pull it up and the roots carry beaded chains of galls of varying size with few fine roots.
Gray Mold
Disease
Water-soaked brown lesions form on flowers, fruit and leaves, densely covered by a fuzzy gray mold. Fruit rots and drops, and decay continues in storage after harvest.
Leaf Spot
Disease
Small round brown to gray-white lesions appear on the lower leaves, the centers turning gray with tiny black specks. As they multiply the leaf yellows and drops early.
Ring Rot
Disease
The bark of branches and trunk becomes rough and warty, serving as the inoculum source. Fruit develops round brown lesions that soften and rot in concentric rings.
