Botrytis vs. LALSTOP G46 WG: The Petri Dish Test

Botrytis cinerea, also known as grey mold, is a major fungal pathogen affecting a wide range of crops, causing significant yield losses and quality deterioration. Effective disease management is essential to protect crops, and integrating biocontrol solutions like LALSTOP G46 WG can be a sustainable and efficient approach.

LALSTOP G46 WG is a biological fungicide containing the beneficial fungus Clonostachys rosea strain J1446. Once applied, it colonizes plant surfaces, creating a protective barrier that limits the spread of pathogens like Botrytis cinerea.

In this video, we present a comparative study using Petri dish assays to illustrate how LALSTOP G46 WG interacts with Botrytis cinerea:

When Botrytis cinerea is alone, it rapidly spreads across the medium.
When applied simultaneously, LALSTOP G46 WG establishes itself and restricts the pathogen’s growth.
When applied preventively few days before Botrytis inoculation, LALSTOP G46 WG provides even stronger protection, significantly reducing Botrytis cinerea colonization.

These results suggest that a preventive application of LALSTOP G46 WG is the most effective strategy to control Botrytis cinerea and protect crops.

By giving beneficial microorganisms a head start, we can better control the disease and protect crops more effectively!
