Circa late-1990s. I was sitting at Inness Farm Supply, a plate of BBQ on my lap, listening to the Monsanto rep carry on about the advantages of Roundup Ready Corn. After hearing all the benefits, I asked THE question. “Won’t this accelerate weed resistance?” She looked at me like she wanted to summon security. Then she emphatically assured the group that resistance was not a possibility. I just smiled and replied that nature always finds a way. It did. In 2000, resistant horseweed was discovered on the East Coast. Today, 18 weed species across 38 states are resistant to glyphosate, the active ingredient in Roundup.
Beating High Phosphorus Prices
Phosphorus prices for 2026 are painful, but cutting fertilizer rates isn’t the only option. By switching to more efficient sources like SUPER PHOS and unlocking tied-up nutrients with K-HUME, growers can stretch their phosphorus dollars while still pushing for top-end yields.

This year,
