Carrot Powdery Mildew
(Erysiphe polygoni) Credits: Biovision-Infonet The disease is caused by the fungus Erysiphe polygoni (E. heraclei). It is characterised by the development of white, powdery fungal growth on leaves. Affected leaves become chlorotic and eventually die. The fungus is seed-borne. What to do: Use certified disease-free seeds if using own seeds hot water treat the seeds. […]
Carrot Bacterial Soft Rot
(Erwinia carotovora var. carotovora) Credits: Biovision-Infonet Erwinia carotovora subsp. carotovora is a bacterium. Bacteria survive in decaying refuse and enter the root principally through cultivation wounds, harvest bruises, freezing injury, and insect openings. After infection, high humidity is essential for progress of the disease. When soft rot occurs in the field, it usually follows a […]
Damping-off on Carrot
(Phythium sp.) Credits: Biovision-Infonet Damping-off diseases are caused by a complex of plant pathogens (disease inciting agents) including Alternaria spp., Fusarium spp., Pythium spp. and Rhizoctonia solani. These pathogenic fungi may cause rotting of seeds before emergence or death of seedlings after emergence. The most disposing factors are use of non-certified disease-free seeds and excessive […]
