Black Turfgrass Ataenius Damage Thresholds
Since bentgrass greens in desert golf courses are vulnerable to injury from black turfgrass ataenius (BTA) beetles (Ataenius spretulus), UCR entomologists have determined when damaging populations are likely to be present and have identified an economic injury level superintendents can use to implement control measures. “The threshold levels for damaging populations of BTA on bentgrass in the l...
متن کاملPPA-1: Chemical Control of Turfgrass Diseases
T under intensive management are often subject to outbreaks of infectious diseases. Diseases usually are most damaging when weather or cultural conditions favor the disease-causing agent but not plant growth and vigor. Cultural conditions that enhance turfgrass diseases include close mowing, inadequate or excessive nitrogen fertility, light and frequent irrigations, excessive thatch, poor drain...
متن کاملCalifornia Turfgrass Culture
Wetting agents can be used to increase infiltration rates into hydrophobic (water repellent) soils. A field test was conducted on a soil classified as Tujunga stony sandy loam, which was found to be extremely hydrophobic to learn more about the effectiveness of wetting agents. The area is located near Fontana. The land had been farmed in small grain crops years ago and then was used as a hog ra...
متن کاملSystem Pinpoints Stressed Turfgrass
Turfgrass managers spend a significant amount of time monitoring their turfgrass fertility and irrigation programs to ensure the most efficient use of their resources while minimizing potential environmental impacts. Characterizing the spatial variability of nutrients across a golf course or large sports facility requires careful observation and periodic collection of soil and tissue samples. R...
متن کاملTurfgrass Root Basics
P turfgrasses are characterized by an extremely fine, fibrous root system. This leads to considerable frustration on the part of researchers due to the time-consuming, costly procedures required to accurately study and measure turfgrass roots. Nevertheless, the monitoring of rooting depth and functional viability on a regular basis is an important dimension in any turf manager's information ass...
