Growers across much of the corn-growing region should continue to monitor their crops for corn rootworms. Later planted and slower maturing crops are especially at risk especially if fresh silks are still present. Fields from Colorado into Kansas, Colorado, South and North Dakota, Minnesota, Iowa, northern Missouri, central and northern Illinois, Wisconsin, Michigan, Indiana, Ohio, and southern Ontario, Canada are all at risk with the greatest threat generally along and north of I-80. All growers should monitor their fields even if crops are past critical stages as beetle problems now will likely mean corn rootworm problems in 2014. Treatment options are also recommended if you are above threshold values to help reduce risk next growing season.
