Vegetable Garden Disease Prevention: Keep Your Crops Healthy

Start Clean, Stay Clean

Water early so foliage dries before evening.
Avoid splash‑borne spread: space plants adequately, use drip irrigation or soaker hoses.

Insects (aphids, leafhoppers) transmit viruses—manage them promptly.
Humans & animals carry pathogens (e.g., tobacco mosaic virus on gloves/tools). Sanitize hands and tools between beds.
Weeds host microbes and insects—keep beds weed‑free.

Crop	Disease	Symptoms	Action
Lettuce	Sclerotinia (white mold) / Botrytis (gray mold)	Damp, rotting base	Remove affected leaves or whole plant
Lettuce	Spinach mosaic virus	Blotchy, yellowing, limp leaves	Plant resistant varieties
Asparagus	Fusarium crown rot	Yellow, spindly spears; rotted roots	Remove infected plants
Asparagus	Rust (Puccinia)	Reddish spots on spears	Avoid overwatering
Tomatoes	Early blight / leaf spots	Dark lesions on lower leaves, esp. cool summers	Keep leaves dry; avoid walnut‑tree proximity

Early detection + targeted removal = minimal losses. Healthy soil, smart watering, and vigilant observation are your best fungicides.
