Wildflowers attract wildlife, increase pollinator habitat, and enhance the aesthetic value of landscape. Wildflower establishment is increasingly part an effort to reduce maintained turfgrass on golf courses, lawns, other environments. Weed competition decreases wildflower results in poor long-term stands. Research was conducted a controlled environment investigate tolerance species common post...

This work investigated the adsorption of 2,4-dichlorophenoxyacetic acid (2,4-D) on various activated carbon cloths (ACCs) prepared from a phenolic resin commercially known as Novoloid. Experimental adsorption equilibrium data were obtained in a batch adsorber. The effects of temperature and pH on the adsorption capacity of ACCs were studied and it was found that the adsorption capacity decrease...

Herbicide mixtures are commonly used in agriculture to broaden the spectrum of weed control. The interactions or the combinations may be desirable or undesirable. Acetachlor at 150g/ha applied and ready mix application of anilofos and ethoxysulfuron at 780 g /ha provide effective control of weeds with higher grain yield. Tank mix application of metribuzin with isoproturon at 1.0 kg/ha, clodinof...

The relationship between plant roots and interrill soil erosion is important in dynamic soil erosion predictions. Rainstorm simulations of similar intensity (63.5 mm h-1) were conducted in the summer of 1989 on 1 by 1 m field plots of Cecil sandy loam (clayey, kaolinitic, thermic Typic Kanhapludult) to study the effect of different root length densities, L(v) (cm cm-3), of corn (Zea mays L.), d...
