incidence of airborne aspergillus flavus spores in cornfields of five states.airborne aspergillus flavus spores were rarely detected throughout the 1975 growing season by the agar plate method at cornfield sites in georgia, illinois, maryland, south carolina, and virginia.1978416756
results of a nationwide survey to determine feedstuffs fed to lactating dairy cows.a nationwide survey to determine feedstuffs used in the diets of dairy cows was conducted. this survey was mailed to dairy nutritionists at universities in each state to describe the use of 144 feedstuffs. twenty-eight states responded and were grouped by region as follows: northeast (maine, maryland, new hampshire, new york, ohio, vermont, and west virginia), northwest (idaho, oregon, and washington), midwest (iowa, illinois, michigan, minnesota, missouri, nebraska, north dakota, south dakota, ...199910068966
transport and fate of nitrate and pesticides: hydrogeology and riparian zone processes.there is continuing concern over potential impacts of widespread application of nutrients and pesticides on ground- and surface-water quality. transport and fate of nitrate and pesticides were investigated in a shallow aquifer and adjacent stream, cow castle creek, in orangeburg county, south carolina. pesticide and pesticide degradate concentrations were detected in ground water with greatest frequency and largest concentrations directly beneath and downgradient from the corn (zea mays l.) fiel ...200516275729
spatial and temporal dynamics of stink bugs in southeastern farmscapes.a 3-yr study (2009-2011) was conducted to examine the spatial and temporal dynamics of stink bugs in three commercial farmscapes. study locations were replicated in south carolina and georgia, in an agriculturally diverse region known as the southeastern coastal plain. crops included wheat, triticum aestivum (l.), corn, zea mays (l.), soybean, glycine max (l.), cotton, gossypium hirsutum (l.), and peanut, arachis hypogaea (l.). farmscapes were sampled weekly using whole-plant examinations for co ...201525843577
spatial distribution of stink bugs (hemiptera: pentatomidae) in wheat.a two-year study was conducted in south carolina wheat (triticum aestivum l. (poales: poaceae)) fields to describe spatial and temporal dynamics of stink bugs (hemiptera: pentatomidae), which were sampled weekly with sweep nets. in 2010, the main phytophagous stink bugs caught in a grid sampling plan across two fields were the brown stink bug, euschistus servus (say), the rice stink bug, oebalus pugnax (f.), the southern green stink bug, nezara viridula (l.), and the red shouldered stink bug, th ...201425205358
accumulation of biomass and mineral elements with calendar time by corn: application of the expanded growth model.the expanded growth model is developed to describe accumulation of plant biomass (mg ha(-1)) and mineral elements (kg ha(-1)) in with calendar time (wk). accumulation of plant biomass with calendar time occurs as a result of photosynthesis for green land-based plants. a corresponding accumulation of mineral elements such as nitrogen, phosphorus, and potassium occurs from the soil through plant roots. in this analysis, the expanded growth model is tested against high quality, published data on co ...201122194842
spatial distribution of the cereal leaf beetle (coleoptera: chrysomelidae) in wheat.a 2-yr study was conducted in wheat fields in south carolina involving weekly sampling of cereal leaf beetle, oulema melanopus (l.). in each of the six fields of this study, temporal patterns showed two distinct peaks in march and in may of adult o. melanopus. populations decreased as wheat plants matured. in 2009, larval populations had one peak in april in between the two adult peaks. the χ(2) statistics for observed and poisson predicted distributions of o. melanopus indicated nonrandom distr ...201022182561
