DuPont Has Two New Fungicides Coming

Near Carman DuPont expects two of its new fungicides will commercially available to Manitoba farmers next year, and says more is to come.

There s lots new coming from DuPont, Dave Kloppenburg, DuPont s launch manager for new insecticides and fungicides said Aug. 3 at the company s research farm. The message is next year, yeah, we ll have some new products, but it will continue for the next five years we ll have waves of new technology introduced into the Western marketplace.

The fungicides are Acapela, a new Group 11, with the active ingredient pyraclostrobin and Vertisan, a new-generation Group 7 with penthiopyrad as the active ingredient.

Acapela, once registered, will be used on the following crops and diseases:

* Cereals stem rust, net blotch, powdery mildew, septoria leaf blotch and tan spot.

* Corn common rust, grey leaf spot and northern corn leaf blight.

* Soybeans Asian soybean rust, brown spot and frogeye leaf spot.

* Pulse Crops ascochyta blight, mycoshaerella blight, Asian soybean rust and sclerotinia rot (white mould).

Other strobilurin fungicides have been around for around 10 years, but Acapela has four major improvements, according to DuPont. One is how fast it s taken in by the plant s leaf.

That s a very important attribute for a fungicide because most of the time you re going to be spraying from the top and getting very good coverage on the upper canopy but the bottom of the leaf has not received direct treatment of product, said Frederic Beudot, DuPont s Canadian marketing manager.

Acapela is also systemic, providing some protection for new tissue. It also has vapour activity, helping to spread the fungicidal protection between plants.

Unlike other strobilurin fungicides, Acapela is effective in controlling sclerotinia, according to Kloppenburg. Work is underway to add sclerotinia control in soybeans to the label later and probably anthracnose in pulses as well, he said.


Vertisan, which has a chemistry known as Succinate Dehydrogenase Inhibitor (SDHI) or as a Complex II inhibitor, will be used in canola, sunflowers, pulses and potatoes. While it s not a new class of fungicide many fungal diseases have not been exposed to it, Kloppenburg said.

Head rot has been a devastating disease for sunflower production in Manitoba and we re really excited to have a new product that will control sclerotinia head rot for sunflowers, he said.

In 1980 Manitoba farmers seeded 300,000 acres of sunflowers. Last year there were 160,000 and this year just 34,000 due mainly to the lack of head rot control, said DuPont field biologist and Carman Research Station manager Frances Boddy.

Khalid Rashid, an oilseed crops pathologist with the Agriculture and Agri-Food Canada s Morden Research Station, found Vertisan controls head rot best with split applications, she said.

Vertisan also controls early blight and rhizoctonia in potatoes.

Besides the new fungicides, DuPont has new insecticides coming. A new active ingredient called HGW86 is expected to become a canola seed treatment eventually, Kloppenburg said. The insecticide not only controls flea beetles, but cutworms.

We anticipate being in that seed treatment business in the not-too-distant future, Kloppenburg said.

The insecticide cyazypyr has very good lepidoptera control and could become a product used on banded sunflower moths, sunflower beetles, and seed weevils, Boddy said.

It s likely going to be used to control insects in cereals and canola too, Kloppenburg said.

DuPont is also working to register cyazypyr on potatoes as an in-row treatment for Colorado Potato Beetles.

DuPont is committed to introducing new crop protection products and genetically modified crop traits, said John Chrosniak, DuPont s North American Business manager for crop protection.

We re going to continue to invest nearly a quarter of a billion dollars every year in developing new crop protection solutions, he said.

Almost $1.7 billion of the revenue we earn is ploughed back into R &D. Of that more than half is dedicated to advancing agriculture.

DuPont, which was created 209 years ago, had $34 billion in gross sales in 2010. In addition to crop protection the company is in seed through Pioneer Hi-Bred, which it owns. [email protected]
