Abstract

The effects of a gall mite (Aceria malherbae) and sublethal doses of either 2,4-DB or glyphosate on field bindweed growth were evaluated under laboratory conditions. Mite feeding reduced field bindweed shoot biomass 37 to 48% and root biomass 46 to 50%. 2,4-DB at 0.07 to 0.14 kg ae ha−1 or glyphosate at 0.14 to 0.28 kg ai ha−1 reduced field bindweed root biomass 25 to 52%. Combining A. malherbae feeding with either 2,4-DB or glyphosate application reduced root biomass of field bindweed plants more than mites or either herbicide alone. Live A. malherbae were present on field bindweed 3 wk after treatment with either herbicide. Combination of A. malherbae with sublethal herbicide doses may allow for field bindweed suppression while reducing potential herbicide injury to crops and maintaining A. malherbae populations.
