Confirmation And Control Of Imazamox-Resistant Shattercane, V. Kumar, R. Liu, T. L. Lambert, R. Perumal, B. Bean

Kansas Agricultural Experiment Station Research Reports

Shattercane is a summer annual grass weed species commonly found in grain sorghum producing regions, including Kansas. Recent development and commercialization of grain sorghum hybrids with tolerance to acetolactate synthase (ALS) and acetyl-CoA-carboxylase (ACCase) inhibiting herbicides will allow producers to use these herbicides for in-season control of shattercane. In a recent field survey, three shattercane populations (DC8, GH4, and PL8) collected from sorghum fields in northwestern Kansas survived the field-use rate (6 fl oz/a) of postemergence (POST) applied IMIFLEX (imazamox). The main objectives of this research were to (1) confirm and characterize the level of resistance to imazamox in those …

Kansas Agricultural Experiment Station Research Reports

Research efforts to improve cultivar quality include selecting for disease resistance and stress tolerance as well as finer leaf texture, a rich green color, and better sward density. Several cultivars included in the 2012 National Turfgrass Evaluation Program Tall Fescue Test performed well and showed good brown patch resistance in south central Kansas throughout the course of the study.
