Bekämpfung des Schneeschimmels (Microdochium majus) bei Winterweizen mit Naturstoffen – vom Labor ins Feld Organic Eprints
Vogelgsang, Susanne; Bänziger, Irene; Krebs, Heinz; Legro, Robert; Sanchez-Sava, Victor; Forrer, Hans-Rudolf.
The fungal pathogen Microdochium majus, causing snow mould, seedling blight or foot rot results in severe yield losses in small grain cereals. There are few options to control this pathogen in organic production. In this study, aqueous extracts and powders from the botanicals chamomile, meadowsweet, thyme and Chinese galls were tested in vitro against M. majus conidia germination and mycelial growth. Subsequently, powders of three chosen botanicals were tested for their effect on emergence of M. majus infected wheat seedlings from soil in climate chambers. Furthermore, seed treatments with warm water, a commercialised bacterial product and one chosen botanical were tested in a field experiment throughout three consecutive years. Of the botanicals tested,...

Bekämpfung von Microdochium nivale (Schneeschimmel) auf Weizen mit Präparaten auf Pflanzenbasis Organic Eprints
Vogelgsang, Dr. Susanne; Bänziger, Irene; Krebs, Heinz; Legro, Robert; Forrer, Dr. Hans-Rudolf.
Snow mold, caused by the fungal pathogen Microdochium nivale, is an important seed-borne disease of various cereals and fodder plants, leading to reduced stands after emergence. No agricultural measures are known to prevent snow mold, hence, direct control measures are needed. For organic agriculture, seed dressing with plantbased products could be an alternative. In contrast to spray treatments onto the crop, the formulation and application of plant preparations onto seeds represents a greater challenge in terms of adhesion, persistence, and lasting efficacy. In the current study, three plant-based powders applied with two different seed coating materials were tested for their efficacy against MN of wheat. Both adjuvants demonstrated equally...
