Submission from Lallemand

The innovation.

LALSTOP G46 WG is an innovative crop protection product based on a living ascomycete fungus known as Clonostachys rosea strain J1446.  This naturally occurring organism and strain J1446 was originally isolated from Finnish soil in 1993 as part of a project to control cereal seed pathogens like Fusarium, Rhizoctonia and Pythium. LALSTOP G46 WG has a range of modes of action in that it: 1) outcompetes pathogenic organisms for space and nutrients on plant surfaces and around roots (competition), and 2) attacks and feeds on key pathogens to reduce their potential to infect plants and cause disease (hyper-parasitism).

The benefits.

After years of research, Lallemand has demonstrated formidable effectiveness of LALSTOP G46 WG against major crop diseases such as Botrytis cinerea and Powdery Mildews, which cause significant economic losses for farmers growing fruit, wine grapes, vegetables, herbs and ornamental crops. The expertise we have acquired on this fungus means that we are now able to make very precise recommendations for its use, considering factors such as climatic conditions, periods of use, crops sensitivity to the disease, volume of water to apply, and of course dose rate linked to the crops stages. To support global registration processes, data has been developed to prove LALSTOP G46 WG is safe to humans (workers & handlers, growers, consumers) and the environment (beneficial insects, bees, aquatic species, birds, wildlife). This ensures farmers can use the product without risk to human health or the environment, while effectively controlling target pathogens. 

Use of LALSTOP G46 WG allows farmers to reduce their reliance on chemical applications within IPM (Integration Pest Management) programs. This not only helps maintain the long-term effectiveness of these chemicals by reducing pathogen resistance, but also results in less residue in harvested produce. The fungal strain in LALSTOP G46 WG is officially listed as a tool for resistance management with the internally recognized Fungicide Resistance Action Committee (FRAC) and is compatible with both IPM and organic growing programs.  In addition, the product LALSTOP G46 WG is listed with organic production certifiers globally as available for use in the production of organic agriculture. It is registered and commercially marketed in the following countries as a “low risk” pesticide:  Belgium, Canada, Czech Republic, Denmark, Ecuador, France, Iceland, Latvia, Lithuania, Netherlands, Portugal, Spain, Sweden, United States of America, Uruguay and is pending approval in Argentina, Chile, and South Africa.
