Diseases & pests on this plant

• sweet potato feathery mottle virus (SPFMV)Sweet potato feathery mottle virus

  Faint pale or chlorotic spots, irregular feathery patterns along the veins and purple-ringed chlorotic spots appear on the leaves; symptoms are often mild on their own but become severe when the plant also carries a second virus, stunting growth and cracking or distorting the storage roots. Many infected plants look almost normal, which is how the virus spreads unnoticed.

• silverleaf whiteflyBemisia tabaci

  Tiny white moth-like adults flying up from disturbed leaves, sticky honeydew on lower leaves and fruit, sooty mould secondary growth, silvering between veins on cucurbits, irregular ripening on tomato/pepper.

• two-spotted spider miteTetranychus urticae

  Yellow stippling on upper leaf surface, fine webbing.
