FUTURISTIC FUNGICIDES

Published online: Apr 20, 2017 Chemicals

“As an industry, we are very much challenged as far as bringing new chemistry out,” says Rob Golembiewski, green solutions specialist with Bayer CropScience. “The EPA’s environmental regulations are only getting more stringent. They have definitely tightened down. It’s becoming more and more challenging to get new fungicides registered.”

Despite these challenges, control products companies are using technology to unveil new fungicides.

For example, Golembiewski says, the industry is increasingly taking a “two-pronged” approach with fungicides designed to improve the plant’s ability to stand up to stress, so that the plant is healthier and less of the active ingredient in the fungicide is needed to suppress or control disease.

Golembiewski expects that trend to accelerate: “I think we will probably see fewer new true synthetic fungicides and maybe more blends or combinations with other additives or ingredients in those formulations that will have a positive impact on plant health and performance, and the ability to mitigate stress, and that this will optimize active ingredient or fungicide in that mix to perform,” he says. In other words, improving the plant’s ability to stand up to stress will make it healthier, so that less fungicide is needed to suppress or control disease.

An example of a fungicide that incorporates these added plant health benefits is Bayer’s newly introduced Signature XTRA StressGard, which uses an existing active ingredient (fosetyl-Al) in a new formulation that’s designed to “enhance plant health and turf quality, while minimizing stress from both abiotic and biotic sources.”

The advent of more extreme weather patterns is, to an extent, behind the development of these new fungicide technologies, says Syngenta technical manager Dr. Lane Tredway.
