Direct toxic injury to turfgrasses by atmospheric pollutants is a new factor affecting the growth and look of turfgrasses. Although the complete loss of a turf from these toxic atmospheric gases or aerosols has rarely been observed to date, the injurious effects, however, a) reduce drastically the visual quality of turfgrass, b) lowers carbohydra te reserve because of injury to plant chlorophyl...

Ten cultivars of seashore paspalum, Paspalum vaginatum Swartz, were compared for their response to Japanese beetle, Popillia japonica Newman, larval root feeding. Cultivars of Bermuda grass, Cynodon sp., and zoysiagrass, Zoysia sp., also were included for comparison. Turf grown in pots in the greenhouse was infested with second and third instars in this 2-yr study. Grub survival and weight gain...

A metal detector was used to relocate steel pins marking the boundaries of semipermanent plots in cranberry bogs and turfgrass where continuous use precluded the placement of permanent wooden stakes.

t AST month we talked shout training men and about the new Turfgrass Short Course at Penn State which is to be activated this fall. It seems important now to examine another phase ol leaching in the turfgrass field — that of extension service. In effect, it » the university extended to the field It is wholly tax supp o r t e d , operating statewide in countv units with administrative heads loca...

Rationale White grubs (e.g. larvae of Japanese beetles or masked chafers) are the most destructive and economically injurious pests of turfgrasses in the Midwest and eastern United States. Developing grubs feed on turfgrass roots at the soil/thatch interface or in the first few centimeters of soil. Visual evidence of an infestation includes thinning, wilting in the presence of adequate irrigati...

Phytoremediation efficiency mainly depends upon mechanisms in the uptake and translocation of soil contaminants. Cadmium (Cd) distribution and translocation in roots and shoots of tall fescue (Festuca arundinacea) and Kentucky bluegrass (Poa pratensis) were observed using fluorescence spectroscopy with a laser confocal scanning microscope. No difference in root Cd accumulations was detected bet...

Bermudagrass (Cynodon sp.) and paspalum (Paspalum vaginatum) genotypes were evaluated in laboratory, greenhouse, and field experiments for potential resistance to the common turfgrass pests, tawny mole cricket (Scapteriscus vicinus Scudder) and southern mole cricket (Scapteriscus borellii Giglio-tos). Potential resistance among 21 seashore paspalums to both insects in an environmental chamber a...

D r. George Wallace a researcher from UCLA, writing in HortScience called the 1980s the decade for advancement in our knowledge of iron (Fe) and plant nutrition. He states: "More progress was perhaps made in the 1980s on understanding and management of Fe chlorosis in plants than during the previous 150 years since it became known that Fe deficiency was involved in the chlorosis." Iron is used ...
