Grass selections including 10 zoysiagrasses, 18 paspalums, 34 Bermuda grasses, tall fescue, creeping red fescue, and perennial ryegrasses with and without endophyte were evaluated for potential resistance to fall armyworm, Spodoptera frugiperda (J. E. Smith), larvae. Laboratory evaluations assessed the degree of antibiosis among >70 grass lines to first-instar fall armvworms. When all parameter...

introduction: water is the main carrier of herbicides (hc) that its quality plays an important role in herbicide performance hard water has a high concentration of ca++ and mg++ and reviews have shown that calcium, manganese and zinc are the main factors reducing the effectiveness of weak acid herbicides. weak acid herbicides such as glyphosate, paraquat, clethodim and 2, 4 d are compounds that...

Roughstalk bluegrass (Poa trivialis) is a weed in cool season grass seed production fields in Oregon. Populations of this weed are often greater in fields prone to waterlogging. A greenhouse study was conducted to investigate the morphological and physiological differences between recently established roughstalk bluegrass and tall fescue (Lolium arundinaceum) plants in response to simulated wat...

Abstract Bare sandy flats at and below low tide level of the Wadden Sea (eastern North Sea, European Atlantic) were observed in 2020 to have been invaded by an introduced grass-like alga, Vaucheria cf. velutina (Xanthophyceae). A dense algal turf accumulated stabilized mud, where resident seniors lugworm Arenicola marina had reworked rippled sand . Algae worms incompatible. Initially, rising pa...

Shortly after the opening of the Houston Astrodome in 1965, turfgrass specialists realized the difficulty of growing natural grass indoors. The solution was the introduction of Astroturf . Astroturf was developed as a short-pile carpet with pad laid over a concrete surface. The advantage for the stadium owners was the very low maintenance costs. However, since its introduction many coaches, pla...

Forage and turf grasses are continually cut and grazed by livestock, however very little is known concerning the perception or molecular responses to wounding. Mechanical wounding rapidly activated a 46 kDa and a 44 kDa mitogen-activated protein kinase (MAPK) in six different grass species. In the model grass species Lolium temulentum, the 46 kDa MAPK was rapidly activated within 5 min of wound...
