Pepper leaf spot, caused by either Xanthomonas bacteria or Cercospora fungus, damages leaves and reduces yields. Bacterial leaf spot creates water-soaked lesions with yellow halos and scabby fruit. Fungal leaf spot produces distinctive "frog-eye" circular spots but doesn't infect fruit. Early identification, proper water management, and preventive fungicides control both diseases effectively.

Phytophthora blight, caused by the water mold Phytophthora capsici, destroys pepper plants through crown rot and root rot. This aggressive pathogen thrives in warm, wet soil and can eliminate entire crops in weeks. Early identification, prevention strategies, and integrated management approaches protect your peppers effectively.

Pepper bacterial spot, caused by Xanthomonas bacteria, destroys pepper plants through leaf lesions and fruit rot. Yellow halos surround angular dark spots while brown scabbed areas disfigure fruit, making produce completely unmarketable. Understanding identification, prevention, and treatment strategies protects your entire pepper harvest effectively.

Gummy stem blight, caused by the fungus Didymella bryoniae, destroys cucumber plants through stem cankers and fruit rot. Golden brown ooze drips from infected stems while dark rot covers fruit, making produce completely unmarketable. Understanding identification, prevention, and treatment strategies protects your entire harvest effectively.

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.
