Cucumber

Cucumber scab disease, caused by the fungus Cladosporium cucumerinum, attacks all plant parts but causes most damage to fruit. Small sunken spots develop into deep cavities with olive green velvety growth, making produce unmarketable. Understanding identification, prevention, and treatment strategies protects your harvest effectively year after year.

Cucumber mosaic virus (CMV) transmitted by aphids has no chemical cure once plants infect. Over 300 plant species susceptible. Mosaic leaf patterns and deformed fruit result. Certified virus-free seed, aphid control, weed management, and resistant varieties offer your only defense against devastating crop loss.

Cucumber bacterial wilt caused by Erwinia tracheiphila has no chemical cure once plants infect. Striped cucumber beetles transmit the pathogen exclusively through feeding wounds. Early season prevention using resistant varieties, row covers, trap crops, and insecticides offers your only defense against rapid plant death.

Cucumber anthracnose caused by Colletotrichum orbiculare destroys fruit and persists in soil for years. Sunken black lesions with orange discharge render fruit unmarketable. Multiple pathogen races complicate management. Resistant varieties, drip irrigation, wide spacing, crop rotation, and preventive fungicides offer your best defense.

Cucumber downy mildew threatens global production with aggressive Clade II pathogen strains. Yellow leaf spots and gray-white cottony growth signal infection. Early detection combined with resistant varieties, drip irrigation, wide spacing, and preventive fungicides offers your best defense against complete crop loss.
