Efficacy testing of novel organic fungicides and elicitors: from the lab to the field [PDF]

, 2006
Novel organic fungicides and elicitors against downy mildew on grapevines were evaluated on grapevine seedlings in a series of indoor screening experiments under controlled conditions and, if they have shown a good efficacy indoors, in a screening ...

Leaf Diffuse Reflectance Spectroscopy for Early Detection of Ceratocystis Wilt in Eucalyptus Cuttings

Forest Pathology, Volume 55, Issue 6, December 2025.
ABSTRACT The increasing global demand for products derived from Eucalyptus spp. has stimulated its production in Brazil. However, productivity has declined in recent years due to several factors, with Ceratocystis wilt being one of the most significant.

Erarbeitung von wissenschaftlichen Ansätzen zur biologischen Kontrolle der Rebenperonospora und für Strategien zu deren Regulierung im ökologischen Weinbau [PDF]

, 2003
Im ökologischen Weinbau sind Alternativen für Kupfer zur Bekämpfung der Rebenperonospora dringend erforderlich. Verfahren zur biologischen Bekämpfung sind erwartungsgemäß dann am erfolgreichsten, wenn sie an einer Schwachstelle des Erregers ansetzen. Zur

Impact of Piper betle leaf extract on grape downy mildew: effects of combining 4-allylpyrocatechol with eugenol, α-pinene or β-pinene

Plant Protection Science, 2019
Methanol extract of Piper betle leaves exhibited an inhibitory effect on grape downy mildew. This extract might contain more than two compounds which have different polarities that suppress grape downy mildew.

A β-1,3 Glucan Sulfate Induces Resistance in Grapevine against Plasmopara viticola Through Priming of Defense Responses, Including HR-like Cell Death

Molecular Plant-Microbe Interactions, 2008
Sulfated laminarin (PS3) has been shown previously to be an elicitor of plant defense reactions in tobacco and Arabidopsis and to induce protection against tobacco mosaic virus. Here, we have demonstrated the efficiency of PS3 in protecting a susceptible

Selection for fungicide resistance throughout a growing season in populations of Plasmopara viticola [PDF]

, 2018
A method for evaluating the potential threat of selection for resistance to organically-based fungicides in populations of P. viticola is needed to screen a large panel of products alternative to copper in organic viticulture.
