Timing probably ranks as the most important issue in farming, especially when it comes to spraying, says Phil Needham, a widely known ag consultant and a National No-Tillage Conference speaker.

After the asian soybean rust scare hit in autumn of 2004, many of us in the sprayer industry began advocating the use of twin flat fan nozzles to better treat the disease. It turns out we were wrong. By creating two spray patterns out of one, twin flat fan nozzles reduce the force of each spray by half, meaning there is not much force with which to penetrate the soybean canopy.

Now that most no-tillers have pretty much mastered the chemical side of pesticide management, they’re paying more attention to application costs, timeliness and equipment selection. This means more no-tillers will be doing more of their own pesticide applications in the future.

Instead of worrying about whether Asian rust is going to hit your no-tilled soybean fields this summer, you should consider spraying fungicides, Wayne Pedersen says. The University of Illinois plant pathologist says it’s likely to pay dividends through control of several late-maturing soybean diseases.
