Controlling cucumber beetles organically
Date:2/17/2009

d muskmelon yields of 75% and 66%, respectively, compared to the control. Rowcovers also significantly increased yield. The number of trapped beetles was significantly higher in the control group than in any other.

Then, in 2004, the study was repeated, but this time the insecticide group was replaced by a combination of Al-plastic and companion plants. Muskmelon weights varied significantly among all groups, with the greatest weights coming from the Al-plastic and companion plant combined groups with rowcovers. Weights in the Al-plastic-only group were greater than in the companion plant-only group.

All of the treatments, except for the insecticide, significantly increased yields compared to control groups. It appeared that some treatments, such as companion plants, may have reduced beetle populations by affecting adults, while others, such as the Al-plastic, may have affected beetle larvae still in the soil.
