KEY STRENGTHS

Exciting SmartStax® product with dual-purpose potential! Tall hybrid with a very good stalk that produces heavy kernels and a lot of tonnage. Works very well in continuous corn.

WEAKNESSES

HPPD herbicide tolerance to 2-3X rates is not great, so follow the labels and don’t overlap.

POSITIONING

This is a really good SmartStax® product that can push for very high yields and also produce tonnage if you need silage corn. It works in nearly all soil types and excels in the high yield environments. The roots are good, but we’ve seen an advantage adding an insecticide in the furrow.

AGRONOMIC & DISEASE RATINGS

The higher the number, the better the performance or rating.

My Hefty 4734 corn was planted two days later than the neighbor’s Mycogen and Hefty came up before. This is going to have to translate into more yield and more money in my pocket!
