Insect Spectrum

SmartStax seeds control a broad spectrum of pests which includes larvae of above-ground insects such as European corn borer, black cutworm, southwestern corn borer, corn earworm, fall armyworm, western bean cutworm, and below-ground feeding larvae of western corn rootworm and northern corn rootworm.

Refuge acres

To prevent or delay insect resistance, growers plant a refuge on their farm. This is an area of non-GM plants where insect can live. These insect will not evolve resistance to GM technology. These refuge acres ensure that rare resistant insects that feed on insect-protected varieties of corn will mate with susceptible insects and slow the development of resistance.

Promotion and branding

Smartstax corn has been advertised and promoted on television, at farm trade shows, and online as Monsanto has geared up for widespread commercial release. Smartstax is sold under the Genuity Brand by Monsanto and the Mycogen brand by Dow, but both companies have the right to sell it under as many names with as many additional technologies as they wish.
