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.

VT4PRO Technology will provide farmers protection against above-ground pests including European corn borer, southwestern corn borer, fall armyworm, black cutworm, western bean cutworm and corn earworm. It will also help farmers with low-to-moderate corn rootworm pressure defend their roots.
