Abstract:
Azaleas differ in their susceptibility to pre- and postemergence herbicides. Treflan (trifluralin) and Surflan (oryzalin) reduced shoot and root growth of certain cultivars. Surflan decreased stem diameter and strength of ‘Hino Crimson’ and ‘Snow’. Image caused foliar injury on the cultivars tested, whereas Poast and Vantage, sethoxydim formulations, did not. Damage caused by other herbicides was cultivar dependent.
