Tomato pests and diseases management guide

The main diseases affecting tomatoes are Early blight, Late blight, Bacterial wilt and Fusarium wilt. The main pests of tomato are Mites, Whiteflies, Leafminers ( Tuta absoluta ) and Thrips. 1. Bacterial wilt  ( Ralstonia solanacearum ) The disease causes rapid wilting and death of the entire plant without any yellowing or spotting of leaves. Total collapse of the plant usually occurring when temperatures reach 32°C and above. Plant wilts while still green. When the stem of a wilting plant is cut across, the pith has a darkened water-soaked appearance, and on squeezing the cut stem, a white, yellow or greyish, slimy exudate may appear. In later stages of the disease, decay of the pith may cause extensive hollowing of the stem. Photo .

Fusarium wilt  ( Fusarium oxysporum  sp.  Lycopersici )
