Defense planning is under way across the country. No-tillers are taking aim at the weeds, insects and diseases that could threaten their soybean crops in 2004. And as the threats to soybeans change - aphids have become a bigger problem in the past couple of years, and fast-acting rust disease seems ready to move into the U.S. from South America - the country's pesticide manufacturers are offering some new alternatives on top of proven performers to guard the fields.

No-Tillers rarely apply post-emergence herbicides without an adjuvant, whether it’s part of the manufacturer’s herbicide formulation or is added during tankmixing. But selecting adjuvants is no easy task, with more than 4,000 products on the market.
