Canadian pulse growers have forever been in a cat-and-mouse game with pulse diseases, which tend to develop resistance to fungicide active ingredients quicker than the diseases of other major crops.

Historically, Groups 3, 7 and 11 have been the only options for disease management on the market. With continuous use there is a growing concern that the current actives may become less effective.
For that reason, the need for a new, effective mode of action against pulse disease was clear. While integrated disease management practices remain crucial, pulse growers need new fungicide actives as tools to protect their valuable crops.

Now, thanks to Corteva Agriscience, they have one.

Zetigo PRM fungicide arrives just in time

Zetigo™ PRM fungicide with Adavelt™ active, a new Group 21 fungicide active ingredient, is poised to be a game changer for pulse growers, providing powerful disease control and elevated resistance management.

It contains a new, novel mode of action – the only Group 21 fungicide available in pulses. Delivering rotational resistance management, this new active ingredient helps to preserve and prolong the use of critical fungicide actives for an effective disease management strategy.

The systemic movement properties of Zetigo PRM deliver more complete coverage and protection. It provides added plant health benefits to increase yield potential and it is ideal for high incidence of diseases like anthracnose in lentils, protecting crop quality and end-use marketability to maximize yield potential and return on investment.

A novel mode of action

Adavelt active (florylpioxamid) is a Group 21 fungicide that provides an entirely new mode of action (MoA) against many pulse leaf diseases.

Adavelt active has no cross-resistance to other modes of action and targets an entirely unique site of action within the pathogen, making it a powerful new resistance-management tool where resistance to existing actives is emerging.

How Adavelt active works

All fungicide active ingredients work by binding to a specific site within a fungal pathogen and shutting it down. All Group 7 fungicides, for example, are known as succinate dehydrogenase inhibitors (SHDIs) because they bind to and inhibit a specific point in the succinate dehydrogenase (SDH) complex. Group 11 strobilurins bind to what’s known as the Qo or Quinone “outside” site. Adavelt active (Group 21) binds to a different site altogether – Qi – offering a new mode of action against fungal pathogens.

Specifically, Adavelt active stops the growth of fungal mycelia, stopping the spread of disease within a plant. It also stops spores from germinating on leaf surfaces and reduces the development of viable pathogen spores, which can spread to nearby plants. It is mainly a preventative fungicide with translaminar activity for uniform protection throughout treated plant tissue.

A game changer for pulse growers

Zetigo PRM fungicide is a pre-mix of Adavelt active (Group 21) and pyraclostrobin (Group 11).

Corteva designed Zetigo PRM thoughtfully to combine two powerful actives that together provide broad spectrum disease control, deliver plant health benefits and act as a rotational break from traditional actives that can be overused.

Adavelt active offers excellent crop safety, high efficacy and a low environmental load. The addition of pyraclostrobin increases plant health and adds a second mode of action for elevated disease control and resistance management now, while prolonging the potential risk of resistance to Adavelt active.

While Zetigo PRM was approved in Canada in 2023 for control of anthracnose in lentils, the potential for Adavelt active in other pulse crops against additional diseases is noteworthy. As the first broad-spectrum picolinamide fungicide for use against Ascomycetes pathogens in over 30 crops, Corteva expects to add new pulse crops (along with new diseases controlled) to the label soon, pending registration.

Protect your valuable lentil crops

With Zetigo PRM fungicide, growers finally have a new tool to defend their lentils against yield-robbing disease and better manage fungicide resistance in their fields.
