New pulse fungicide option offers two modes of action

NEW ORLEANS, La— Multiple modes of action are needed to stop fungal pests from adapting to the tools that farmers are using to control them.

Syngenta is addressing the issue and expanding coverage of crops with its new Elatus fungicide for use in pulse crops. Beans, chickpeas, lentils, field peas and soybeans are all covered under the new product’s registration.

The two active ingredients are benzovindiflupyr and the popular azoxystrobin, Group 7 and 11 products.

Rob Klewchuk of Syngenta said the product sticks to the plant’s waxy layer on the cuticle of the leaf, penetrates over time and provides residual activity.

“It’s also taken up through the xylem and moves up and out to the leaves to protect the plant as it grows,” he said.

“It’s effective on anthracnose, ascochyta and mycosphaerella, which means it supports crop quality and yield potential.”

The fungicide is also registered for Asian soybean rust and powdery mildew and in the U.S. for stripe rust and septoria in cereals and grey leaf spot in corn.

The residual product allows producers a wider window of protection, and the two products help avoid resistance development.

Klewchuk said lentils’ increasing popularity has prompted farmers to grow lentils in areas where they weren’t previously common and by producers with little experience in growing them.

Disease is usually the biggest issue limiting quality and yields, and he said the product will be a good fit for both existing and new growers. It’s a single rate product for all pulse crops, with a case covering 40 acres.

“Farmers will need to apply Elatus before disease gets established,” he said.

The product would Ideally be applied just before or at the onset of flowering.

A second application can be made two weeks after the first if disease is evident after the first application or weather conditions create an agronomic problem.
