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.
