Recent research from North Carolina has suggested that there are times where tankmixing an insecticide with your nitrogen can be cheaper than using scouting and thresholds for cereal leaf beetle. The biggest reason for this is because there is a yield penalty for driving over wheat after jointing and because scouting costs money. However, there are a number of reasons why I do not recommend this for 2014.
A study found a greater yield response was observed when fungicides were applied at R1 compared to V6, with the largest response being when V6 applications were followed by R1 applications.
If the 2010 growing season was any indication, disease management needs to be one of the top things on growers’ lists if they are going to have a great wheat crop, says an Ohio State University Extension plant pathologist.
Asian soybean rust finally appeared in the U.S. last season but had little impact after years of warnings about its potential catastrophic effects on soybean yields. That doesn’t mean the researchers were wrong and no-tillers can ignore the threat.
