Most products gave very good root protection most of the time based on the percentage consistency. From a statistical standpoint, everything in Table 2 from Force 3G down to Capture 2EC provided similar levels of consistency. However, a number of products did not perform well and these can be found near the bottom of the table. It is important to point out that the two seed treatments, ProShield and Prescribe, are very poor at protecting roots from corn rootworm injury. There are other insecticides that give consistently better root protection.
Consistent performance is one factor to consider when using a corn rootworm insecticide.
Other factors worthy of consideration might be cost, pounds of active ingredient being applied per acre, ease of handling, application equipment needed, other pests controlled, restricted-use labeling, and potential hazards to surface water.
