Influence of Annual Bluegrass on Putting Green Trueness and Control of Weedy Poa Species in Kentucky Bluegrass and Creeping Bentgrass Turf
Annual bluegrass (Poa annua L.) and roughstalk bluegrass (Poa trivialis L.) are among the most troublesome grass weeds on golf courses throughout the United States. Herbicides for selective control of these weeds in cool-season fairways are limited and ineffective. Methiozolin is a new isoxazoline …

Phenotypic Plasticity within the Native Perennial Grass, Poa secunda (Sandberg bluegrass), an Important Component of the Western United States Sagebrush Grassland Vegetation
… I investigated the following questions about Poa secunda, a common native perennial grass in sagebrush ecosystems: 1) Can P. secunda respond plastically to directly-manipulated nutrient availability? 2) Does P. secunda respond to the presence of B. tectorum? and 3) Are these plastic responses …

Synthesis and evaluation of pyrazinoic acid loaded polymeric nanoparticles in the treatment of Tuberculosis
… a prodrug that is converted to pyrazinoic acid (POA), the active moiety that exerts its bactericidal effects in macrophages. Low therapeutic drug concentrations of PZA, severe side effects, and poor patient adherence have led to treatment failure and increasing cases of M. tuberculosis resistance …

Growth of roots, rhizomes, and tillers of Kentucky bluegrass (Poa pratensis L.) cultivars and genotypes as affected by fertility level, cutting height, and season
… cultivars and genotypes of Kentucky bluegrass (Poa pratensis L.). Objectives were to study effects of fertility level and cutting height on underground growth of various Kentucky bluegrasses during various seasons and develop a technique for measuring underground growth without disturbing the …

Effects of nitrogen and cutting management on root growth and productivity of a Kentucky bluegrass (Poa pratensis L.) and white clover (Trifolium repens L.) pasture
Nitrogen (N) and defoliation effects on productivity, root growth and soil nitrate (NO3-) in a Kentucky bluegrass and white clover pasture were examined. Nitrogen was applied annually in two equally split applications at rates of 0, 80 or 160 kg N ha -1. After reaching 12.7 cm, plants were cut to …
