Study Examines Snow Mold Solutions for Northwest
Pink snow mold (Mirodochium patch) and gray snow mold [Typhula blight) are the most prevalent and destructive winter diseases on cool-season turfgrass in the northern United States. They are especially destructive in the Intermountain Northwest where deep snow cover may last four to five months. Pentachloronitrobenzene (PCNB, Quintozene) has been use to manage these diseases in turf on golf cou...
متن کاملManaging Snow Mold Diseases of Winter Cereals and Turf
Most snow mold pathogens cause plant injury only under prolonged snow cover, so snow mold diseases are severe primarily in regions where snow cover persists for more than 100 days. Even within these regions, disease occurrence and severity varies greatly from year to year. When disease is severe, individual fungal colonies coalesce, resulting in substantial losses in plant stand (20). In other ...
متن کاملBlack carbon aerosol size in snow
The effect of anthropogenic black carbon (BC) aerosol on snow is of enduring interest due to its consequences for climate forcing. Until now, too little attention has been focused on BC's size in snow, an important parameter affecting BC light absorption in snow. Here we present first observations of this parameter, revealing that BC can be shifted to larger sizes in snow than are typically see...
متن کاملBlack-carbon reduction of snow albedo
Climate models indicate that the reduction of surface albedo caused by black-carbon contamination of snow contributes to global warming and near-worldwide melting of ice1,2. In this study, we generated and characterized pure and black-carbonladen snow in the laboratory and verified that black-carbon contamination appreciably reduces snow albedo at levels that have been found in natural settings...
متن کاملIce-binding site of snow mold fungus antifreeze protein deviates from structural regularity and high conservation.
Antifreeze proteins (AFPs) are found in organisms ranging from fish to bacteria, where they serve different functions to facilitate survival of their host. AFPs that protect freeze-intolerant fish and insects from internal ice growth bind to ice using a regular array of well-conserved residues/motifs. Less is known about the role of AFPs in freeze-tolerant species, which might be to beneficiall...
