Pests and diseases (61)
Problems recorded for this plant, most serious first.
Bacterial Wilt
MajorDisease
Leaves wilt while still green during the day and recover in the morning and evening; after a few days of this the plant dies. Cut the stem and stand it in water and a milky white bacterial ooze streams out in threads.
Thrips
MajorPest
Silvery white to brown scarring spreads over leaf and fruit surfaces. Flowers discolor and drop, and fruit is left with keloid-like scar tissue.
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.
Stone Fruit Disorder of Eggplant
MajorDisorder
Fruit is hard, loses its gloss and stops at a small size without sizing up. Cut it open and almost no seed has formed.
Twenty-eight-spotted Ladybird
MajorPest
The leaf surface is shaved thin, leaving a fine net-like pattern of feeding scars. Heavy feeding browns and kills the leaves and scars the fruit surface as well.
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.
Verticillium Wilt
MajorDisease
Only one side of the lower leaves yellows and wilts, and the symptom moves up the plant. Stem vascular tissue turns pale brown and the plant dies without ever growing well.
Tomato Spotted Wilt
CommonDisease
Brown necrotic spots and ring patterns appear on the leaves and the growing tips shrivel and darken. Fruit develops concentric yellow rings that make it unmarketable.
Helicoverpa Bollworms
CommonPest
Round holes are bored into fruit and buds, the inside eaten out and packed with frass. Rot spreads from the entry hole, leading to fruit and bud drop.
Whiteflies
CommonPest
Shake the plant and a cloud of tiny white insects flies up. Nymphs stay fixed on leaf undersides, and honeydew-fed sooty mold blackens the leaves as the plant weakens.
Southern Blight
CommonDisease
The stem rots at soil level and white silky mycelium spreads over the crown and the surrounding soil surface. Brown sclerotia the size of rapeseed then form and the plant wilts and dies rapidly.
Root-knot Nematode
CommonPest
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
CommonDisease
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.
Tobacco Cutworm
CommonPest
Many larvae gather on the leaf underside and graze the tissue away, leaving white skeletonized patches. Once they disperse they cause heavy damage to leaves, pods and fruit.
Curved Fruit
CommonDisorder
Fruit bends into a bow shape or pinches in partway so that it sizes unevenly. When curved fruit increases, overall plant growth is usually slowing too.
Magnesium Deficiency
CommonDisorder
Yellowing appears between the veins of the lower leaves while the veins stay green, giving a net-like pattern. It later browns and dies back, and is most obvious on plants carrying a heavy fruit load.
