Blackleg (Pectobacterium carotovorum subsp. atrosepticum) attacks potatoes early in the season and is worst in heavy soils and rainy weather.[1]
Symptoms[edit | edit source]
Tell-tale sign is the blackening of the stems at and below ground level. The leaves turn yellow and wilt; eventually the haulm withers.[1]
Treatment[edit | edit source]
None. Lift and destroy affected plants.[1]
Prevention[edit | edit source]
Never plant seed tubers that are soft and rotten. The practice of cutting seed tuber in half to make them go further increases the risk of attack.[1]
