Why Privest?
Designed to control late blight, Privest® has a unique mode of action with ametoctradin combined with potassium phosphonates which primes the plant's natural defence mechanisms. It gives growers much-needed choice and flexibility within their blight programmes.
“Late blight remains a significant challenge for farmers, and the need for effective solutions has never been more urgent,” says Paul Goddard, BASF Specialities Business Development Manager. “Privest, is the first of a new generation of plant protection products that combines two distinct active ingredients using cutting-edge Syn-Tech formulation technology. This synergistic effect provides exceptional control of late blight and offers multiple modes of action to reduce the risk of resistance development.”
Ametoctradin, is uniquely classified under the QioSI chemistry group, setting it apart from all other actives, including traditional CAA and QiI chemistry options.
“It is introducing much-needed variety to blight control programmes which is essential both for mitigating the risk of resistance development and efficacy” adds Paul. “This new product is best used early in the blight season with its non-clashing systemic activity, ‘freeing up’ slots that can be used elsewhere in the programme”.

Over three years, in both SRUC and Eurofins trials, Privest® consistently performed extremely well against ’top drawer‘ standards. Privest® is positioned as an indispensable tool in crop defence. Its innovative approach and multiple modes of action make it a promising ally in the ongoing battle against late blight.
