Alfalfa Pest & Disease Programs - Biological Inputs That Fit Your Spray Window
Natural disease and stress-support program for alfalfa: anthracnose, leaf spots, Fusarium/Verticillium wilt, downy mildew and white mold, plus cold and flooding resilience.
Growing alfalfa with Vegalab
Alfalfa is challenged by a wide disease complex - anthracnose, common leaf spot, Fusarium and Verticillium wilts, Rhizoctonia and Phytophthora root and crown rots, damping-off, downy mildew and Sclerotinia (white mold) - plus cold and flooding stress that opens the door to disease.
Vegalab's natural fungicide and stress-support program helps protect stand health and cutting yield through the season, from seedling through the bud stages. Rates follow the registered label.

Frequently asked questions
What natural fungicide works on alfalfa diseases?
Spore Control (thyme oil) is a broad-spectrum natural fungicide for anthracnose, leaf spots, wilts, downy mildew and white mold, applied foliar with zero PHI/REI - most effective used preventatively.
How do I protect alfalfa from cold and flooding stress?
Biostimulant support (Kelp Boost / Charge BioBoost) helps plants absorb nutrients and recover from cold and water stress, supporting stand health alongside disease control.
