1Average root damage rating (Node Injury Scale 0-3) where damage in the untreated plots exceeded 0.25 or greater that will likely predispose plants to significant yield losses. The untreated plots averaged 1.47. 2Percentage of root masses where damage rating was less than or equal to 0.25 when the untreated equaled or exceeded 0.25. Tests from 2002-2006. 3Insecticide not included if label states “for suppression,” “reduction of,” “aids in control,” or “control of light to moderate infestations only.” 42004-2006 Data only. |
