Variety ratings for corn and soybeanIntegrated Crop Management News
AbstractGray leaf spot severity ratings from the 1998 Iowa Crop Performance Test are now available and include data from seven locations for all hybrids entered in Districts 5, 6, and 7, covering southern and east central Iowa. Two- and 3-year averages are included for hybrids that have been entered since 1996 or 1997. The results will be available in printed form, as Pm-660-GLS, later this month. Gray leaf spot results should be used in conjunction with yield data from the Crop Performance Test to make the best choices for hybrids where gray leaf spot occurs.
