Corn & Soybean Protection

Maximize the Yield and Quality of Corn and Soybean Crops

You can count on DuPont to provide you with reliable, field-proven herbicides, fungicides and insecticides.  Whether you’re growing IP soybeans or glyphosate-tolerant corn or soybeans, we can help.

Corn and soybeans are the heart of crop production in Ontario and Quebec, with a rising profile on the Prairies. Growers look to DuPont for the crop protection they need, through our complete line of high-quality herbicides, fungicides and insecticides.

In recent years, DuPont has added to the level of protection we can offer for your corn and soybean crops. In corn, DuPont™ Coragen® insecticide is now registered to control difficult pests such as corn earworm, European corn borer and Western bean cutworm. We introduced DuPont™ Guardian®  and DuPont™ Guardian® Plus  herbicides, taking broadleaf weed control to a new level.

In 2012 we launched DuPont™ Acapela™ fungicide for disease control in corn and soybeans.  With its one-of-a-kind movement properties, broad-spectrum disease control and unique activity on white mould, Acapela™ is a welcome addition to the corn and soybean grower’s toolkit.  Excellent results in side x side grower trials  in corn and soybeans in 2012 demonstrated the yield and quality benefits of using Acapela™ fungicide.

New for 2013!

DuPont will be offering a new herbicide solution for soybean growers this season called DuPont™ Canopy™ PRO herbicide.  Canopy™ PRO is a new solution that combines DuPont™ Classic® (chlorimuron-ethyl) and a 75% DF metribuzin for GT and IP soybeans.

As important as the reliability of our products is the way we do business. We pride ourselves in having the most knowledgeable people in the field to offer you support and advice.
