Lallemand LALSTOP Contans Wettable Granular, 25 lbs.

LALSTOP® CONTANS WG - Biofungicide

LALSTOP® CONTANS WG is a biofungicide that targets and destroys sclerotia in contaminated topsoil. By reducing inoculum levels, it breaks the disease cycle and lowers the risk of white mold and stem rot in the next crop cycle, ultimately supporting healthier crops and better yields.

Why use LALSTOP CONTANS WG?

• Based on a naturally occurring fungus that poses minimal risk to growers, consumers, beneficial insects, and the surrounding environment
• Flexible application timing: pre-planting/planting or after harvest (on crop residues)
• Compatible with most IPM programs
• No known risk of resistance due to multiple modes of action

Active Ingredient

• Coniothyrium minitans – 1.0 x 10⁹ CFU/g

Targeted Pathogens

• Sclerotinia sclerotiorum
• Sclerotinia minor

Available Sizes

• 25 lb (11.35 kg)

Mode of Action

1. After application, incorporating LALSTOP CONTANS WG into the soil allows its spores to make contact with sclerotia, the survival structures of Sclerotinia fungi and the root cause of infection.
2. The germinating spores penetrate the sclerotia through their germ tube and produce a mycelium.
3. This mycelium attacks and destroys the sclerotia from the inside. Infected sclerotia can no longer generate apothecia or produce Sclerotinia mycelium, lowering the risk of white mold and stem rot in future crops.

Rotation Management

Sclerotia are long-term resting structures of Sclerotinia that can survive in soil for up to 10 years when buried with plant debris. Tillage brings them to the surface, triggering germination and disease spread.

In heavily infested fields, applying LALSTOP CONTANS WG reduces sclerotia levels and disease pressure, especially when used in rotation over several years.
