PLENARIS® uses the most advanced seed applied technology, and is the latest addition to the most comprehensive seed treatment portfolio in the industry. Syngenta Seedcare contributes to sustainable downy mildew resistance management which combines multiple modes of action with the best genetics. PLENARIS® has a new mode of action and controls all races of the genetically variable pathogen, Plasmopara halstedii.
|PLENARIS® contains Oxathiapiprolin* which belongs to the novel chemical group of piperidinyl-thiazole—isoxazolines inhibiting the oxysterol binding homologue (FRAC Code List ©*2017)
|Mode of action
Oxathiapiprolin (OXTP) provides protection against seed- and soil-borne oomycete pathogens, especially downy mildews. It inhibits an oxysterol binding protein (OSBP) homologue, which is involved in the movement of
lipids between membranes. PLENARIS® controls all major stages of the pathogen’s lifecycle and protects the crop against all downy mildew races tested. Is the first from a new class of chemistry and shows no cross- resistance to existing oomycete fungicides (PA, CAA, QoI etc).
|Initially, symptoms of the primary infection are observed in seedling damping-off. If infected plants survive, they will appear stunted and chlorotic mottling is observed on the leaves. Primary infection contributes to economic loss due to the reduction in stand and the development of unproductive heads. If left untreated, the downy mildew will produce zoosporangia, which contributes to secondary infection and survival of the pathogen long-term
|Downy mildew on sunflower
|PLENARIS® is registered on sunflowers in the United States, Argentina and Canada. Future registrations will include EU-28 (e.g. France, Spain, Hungary, Romania, Bulgaria, Germany, Switzerland), Turkey, Serbia, Russia, Ukraine and other sunflower producing countries.
