Poor stand establishment, failure to recover after grazing, and premature plant death have reduced the utilization of arrowleaf clover (Trifolium vesiculosum Savi) as a forage crop in the southeastern United States in recent years. Clover plants coll

A double-antibody sandwich indirect enzyme-linked immunosorbent assay (ELISA) was developed for the detection and quantification of Pythium ultimum. A polyclonal antibody produced to cell walls of P. ultimum was used as the capture antibody, while a

Smooth bromegrass (Bromus inermis Leyss.) is the most common perennial grass species cultivated for forage in North America. During late fall of 2004, smooth bromegrass plants in Lincoln, NE were observed to have brown lesions on leaf midveins that w

Ultraviolet-B radiation (UV-B, 280-320 nm) reaching the earth's surface has deleterious effects on plants. The degree of susceptibility to UV-B is dependent on the amount of energy present in longer wavelengths of ultraviolet-A radiation (UV-A, 320-4

Over 120 bacterial strains were evaluated in a greenhouse for control of bean rust caused by Uromyces appendiculatus . The strains, found previously to be antagonistic to some fungal pathogens, were isolated from dry edible bean ( Phaseolus vulgaris

Shading of the turfgrass canopy is assumed to support increased microbial activity and therefore more potential disease problems. The goal of this research was to determine how shading affects microenvironmental conditions, and how these conditions a
