Rhizoctonia solani is an important soil-borne fungal pathogen, which infects tomato (Lycopersicon esculentum L.) with typical symptoms of seedling damping-off and foot rot.

Two kinds of damping-off. Tomato damping-off and foot rot book are two types of damping off: pre-emergent and post-emergent. Pre-emergent damping-off: seeds rot in the soil or seedlings decay before they push through the soil Post-emergent damping-off: seedlings sprout, but then pale, curl, wilt, or collapse at the soil line.

Pythium usually causes a brown rot of root tips and cortex that may progress up the stem. The root cortex will often slough off. Infected plants are stunted (Fig. 4), and lower leaves may turn yellow, curl, and fall severe conditions, entire plants are killed.

damping off fungi. Alternatively, for direct-seeded tomatoes, use fungicide-treated seed. Fumigate nursery beds or apply a fungicidal soil drench if the disease appears.

The type of fungus that is causing damping-off will determine the most suitable fungicide to use. Consult with your local extension agent to determine the most suitable.

During surveys ( and crop season) of nine tomato growing areas in Pothohar region of Pakistan, symptoms of foot rot were noted on approximately % of the plants observed at soil line level of the stem.

Lesions on infected plant stems were irregular in shape, water-soaked, brown in colour manifesting sunken appearance. Damping off typically occurs when old seed is planted in cold, wet soil and is further increased by poor soil drainage.

High humidity levels, rich potting soils and planting too deeply will also encourage its growth. Fungal spores live in the soil and are primarily a problem in seed beds.

When tomatoes and eggplants are affected by Phytophthora root rot, roots of all sizes develop water-soaked spots that dry out and turn a chocolate brown as the disease becomes advanced. Early infections, caused by Phytophthora and other pathogens that cause damping-off diseases, kill seedlings.

Seed rot, damping-off, black rot (seedling stage). Application of Solubor may reduce damping-off if boron is deficient. Carrot hot water soak, followed by thiram D,S Hot water soak controls seedborne bacterial blight. Thiram controls seed rot and damping-off.

In Januarya severe root and foot rot was observed on 2-month-old wilted tomato (Lycopersicon esculentum Mill.) plants in a large-scale ( ha) commercial greenhouse setting in plants (10%) produced from healthy nursery-grown seedlings and planted to new, clean rockwool and drip irrigation with UV-disinfected water developed symptoms.

Pre- and postemergence damping-off occurs in seedbeds resulting in poor stands. Collar or foot rot may develop on young seedlings and transplants. Collar rot is characterized by a large, girdling, dark brown, slightly sunken, irregular lesion at the base of the stem.

Damping off: the base of seedlings and plants can discolour and shrink, seedlings fall over and die. Root rot can be recognized by the appearance of brown to black root tips, less root development, brown roots, smaller and wilted plants and plants that can be easily pulled from the growing medium.

Foot or crown rot is an infection that occurs. TOMATOES Active soil management is a vital component in promoting a healthy crop and improving profits.
