Wire stem is a disease of brassicas caused by rhizoctonia solani.


Base of stem becomes black and shrunken. Seedlings often die; the plants which survive grow very slowly and stems break easily.[1]




Avoid growing seedlings in wet and cold soil or compost. Cheshunt Compound may help. Avoid over-crowding.[1]
