Clover root weevil feeding becoming obvious

AgPest — Tue, 31 Oct 2017 19:38:19 +0000

Clover root weevil feeding will become obvious in November-January – U-shaped notches at the edge of clover leaves show adults are present. The presence of larvae may be indicated by the pasture appearing nitrogen deficient. While control is generally not an option careful management of clover will help maintain pasture quality. Additional nitrogen may need to be applied to pastures and clover should not be over-grazed. In the South Island this weevil will be appearing in some areas for the first time.

In established pastures with high levels of clover root weevil, the clover may be adding little in the way of nitrogen to the pasture and compensatory nitrogen applications may be required.
