This study was conducted to compare Zest (nicosulfuron) herbicide at two rates and application timings for efficacy in grain sorghum. Palmer amaranth control best when a preemergence (PRE) followed by late postemergence (LPOST) treatment. 0.67 or 1.33 oz/a provided the velvetleaf shattercane control. Either rate of applied early (EPOST) controlled green foxtail more than 90%, but higher require...

Weeds are a major problem in seeding rangeland and cropland to native grasses. However, many immature weedy forbs and grasses are palatable to cattle. Research was conducted using yearling cattle for weed control in big bluestem (Andropogon gerardii var. gerardii Vitman) seedings (1987, 1988) at Mead, Nebraska on a Sharpsburg silty clay loam (fine, montmorillonitic, mesic Typic Argiudoll) soil....

Recovery of common agricultural weeds after burial by soil was studied in four greenhouse and three field experiments. Species studied included velvetleaf, Powell amaranth, common lambsquarters, barnyardgrass, and giant foxtail. Seedlings were bent over before burial to simulate the effect of the impact of soil thrown by a cultivator. Altogether, more than 35,000 seedlings were marked and obser...
