1 Features & Benefits

The Power of RNAi Technology

Developed by Bayer to combat corn rootworm, RNAi Technology offers a specific mode of action against the pest. Because RNAi Technology works differently than a soil-applied insecticide or Bt traits to control corn rootworm, it can help increase a corn plant's ability to defend itself against the billion-dollar bug2.

Proven Herbicide Tolerance

VT4PRO Technology will contain Roundup Ready 2 Technology®, allowing the plant to withstand glyphosate treatments used to prevent weeds. By reducing weeds, plants have better access to crucial nutrients and water.
