Initium®
– key benefits of the new active ingredient
• new active ingredient
• high intrinsic efficacy against different infectious
stages of peronosporomycetes
• strong adsorption to the wax layer
(due to molecule structure, low water solubility
high log Pow)
• very good rainfastness
• redistribution on the leaf under the influence of
moisture
• excellent crop selectivity
• very favourable regulatory profile

Summary of Experiences 2010/2011
with Orvego and Orvego Duo
• Orvego and Orvego Duo provide very good efficacy in Phytophthora infestans spray
programmes.
• Orvego and Orvego Duo can be used without problems in mixtures with other plant
protection products, mineral oils and fertilizers.
• Orvego can be positioned flexibly in the spray program: In the period of active plant
growth as well as in the period of stable canopy very good disease control is ensured.
Furthermore dimethomorph ensures beside preventive efficacy also curative and
antisporulant efficacy. Farmers using Orvego appreciate the easy-to-use liquid
formulation.
• Orvego Duo controls Phytophthora infestans before the infection can establish. Due
to its excellent rainfastness the product ensures long-lasting protection of the crop.
Farmers using Orvego Duo appreciate the 13side effect against Alternaria spp.
