Sensitivity to 2,4-D in Sunflower as an Indicator of Tolerance to the Sunflower Midge (Diptera: Cecidomyiidae)Faculty Publications: Department of Entomology

AbstractNine sunflower hybrids were evaluated for their sensitivity to 2,4-dichlorophenoxyacetic acid (2,4-D) as measured by the production of ethylene. Sensitivity to 2,4-D was then compared with the degree of field tolerance to the sunflower midge, Contarinia schulzi Gagné, exhibited by each hybrid. For the hybrids evaluated, ethylene production increased with 2,4-D concentration and sensitivity to 2,4-D was inversely proportional to midge tolerance. The procedure may be useful in identifying midge tolerant germplasm.
