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.

If clover root weevil is an issue in your area, pasture renewal should incorporate a non-clover break crop.

This weevil cannot survive in the absence of clover, so a clover free break crop provides a temporary weevil free environment that will allow clover seedlings to establish before the weevil reinvades. This will also produce plant nematodes, plant pathogens and weeds, and benefit the new pasture.
