SYSTEMIC BROAD-SPECTRUM FUNGICIDE FOR DISEASE CONTROL IN AUTUMN AND SPRING CEREAL CROPS.
Active substance: 50 g/l proquinazid + 200 g/l prothioconazole
Chemical class: quinazolines and triazoles
Preparative form: concentrated emulsion (CE)
Packaging: 5 l
Mechanism of action
Proquinazid is a chemical molecule of the quinazoline group with preventive and curative effect.
Proquinazid has a systemic and vapour action and moves translaminar, is very resistant to washing and long-lasting effect 4-5 weeks.
Proquinazid blocks the formation of appressoria and the germ tube but also has an antisporulatory role and therefore has a preventive effect.
Proquinazid resists washing out 2 hours after application and has SAR (systemic acquired resistance) action. It acts on genes responsible for the plant's defence response against diseases such as Septoria, Cercospora, Rhyncosporium, Rugini and Pseudopcercospora. Thus, through this reaction the plant is fortified against diseases and when mixed with a triazole such as prothioconazole it becomes a complex acting fungicide.
Prothioconazole belongs to the triazole class of demethylation inhibitors (DMI) and is part of the sterol biosynthesis inhibitor (SBI) class.
Prothioconazole is a synthetic fungicide of the triazolin class with a very broad spectrum of control and curative, preventive and eradicant action.
Prothioconazole acts on fungi by blocking the synthesis of biosterols thereby destroying the cell membrane.
Prothioconazole through its action leads to the destruction of mycelial hyphae and the prevention of germ tube growth.
Prothioconazole is used to combat diseases: Mychospherella spp, Fusarium spp, Erysiphe spp, Phoma, Rhyncosporium, Sclerotinia, Septoria spp, and rusts.
