LALSTOP G46 WG Biofungicide

LALSTOP G46 WG is an EPA-registered biological fungicide made from naturally occurring soil fungi, featuring mycelium and spores of Clonostachys rosea strain J1446. This OMRI-listed biofungicide is ideal for organic gardeners and growers looking for a natural, effective way to protect plants without harsh chemicals. 

LALSTOP G46 WG works with your crop’s natural defenses and is safe to use alongside beneficial insects—making it a smart choice for integrated pest and disease management.

This powerful biological fungicide provides broad-spectrum protection against many common plant diseases, including:

• Gray Mold & Stem Canker (Botrytis cinerea) on tomatoes, peppers, cucumbers, lettuce, herbs, ornamentals, and other fruits and vegetables.

• Gummy Stem Blight (Didymella bryoniae) on cucurbits such as cucumbers, melons, and squash.

• Damping-Off, Crown Rot & Root Rot caused by Pythium, Rhizoctonia, Phytophthora, and Fusarium species across vegetable, herb, and ornamental crops.

• Wilt Diseases caused by Fusarium and Verticillium species on a wide range of fruit, vegetable, and ornamental plants.

• Charcoal Rot (Macrophomina phaseolina) on crops such as strawberries and sweet potatoes.

Mix LALSTOP G46 WG with clean water and apply as a soil drench, root dip, or foliar spray, depending on your crop and disease pressure. See product label for full application rates and detailed directions.
