Technical Abstract: Feeding effects of the gall mite, Aceria malherbae, followed by sublethal doses of 2,4-DB or glyphosate on field bindweed were evaluated under laboratory conditions. Symptoms of Aceria malherbae feeding were malformed, fused, and folded leaves that increased in severity three weeks after treatment with either herbicide. Mite feeding reduced field bindweed shoot and root biomass 37% and more. 2,4-DB at 0.07 to 0.14 kg ai ha-1 or glyphosate at 0.14 to 0.28 kg ai ha-1 reduced field bindweed root biomass by 25 to 52%. Mite feeding followed by either 2,4-DB or glyphosate application reduced root biomass of field bindweed by 72 to 76% compared to nontreated plants. Combining A. malherbae feeding with sublethal herbicide doses may allow for field bindweed suppression while reducing herbicide use.
