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 کاملExport of manure phosphorus and nitrogen in turfgrass sod.
Regulatory mandates have increased demand for best management practices (BMPs) that will reduce nutrient loading on watersheds impaired by excess manure P and N. Export of manure P and N in turfgrass sod harvests is one BMP under consideration. This study quantified amounts and percentages of P and N removed in a sod harvest for different rates of manure and inorganic P and N. Six treatments co...
متن کاملMicrobial control of black cutworm (Lepidoptera: Noctuidae) in turfgrass using Agrotis ipsilon multiple nucleopolyhedrovirus.
Agrotis ipsilon multiple nucleopolyhedrovirus (family Baculoviridae, genus Nucleopolyhedrovirus, AgipMNPV), a naturally occurring baculovirus, was found infecting black cutworm, Agrotis ipsilon (Hufnagel) (Lepidoptera: Noctuidae), on central Kentucky golf courses. Laboratory, greenhouse, and field studies investigated the potential of AgipMNPV for managing black cutworms in turfgrass. The virus...
متن کاملAssessment of a turfgrass sod best management practice on water quality in a suburban watershed.
The disposal of manure on agricultural land has caused water quality concerns in many rural watersheds, sometimes requiring state environmental agencies to conduct total maximum daily load (TMDL) assessments of stream nutrients, such as nitrogen (N) and phosphorus (P). A best management practice (BMP) has been developed in response to a TMDL that mandates a 50% reduction of annual P load to the...
