dna screening reveals pink bollworm resistance to bt cotton remains rare after a decade of exposure.transgenic crops producing toxins from the bacterium bacillus thuringiensis (bt) kill insect pests and can reduce reliance on insecticide sprays. although bt cotton (gossypium hirsutum l.) and bt corn (zea mays l.) covered 26 million ha worldwide in 2005, their success could be cut short by evolution of pest resistance. monitoring the early phases of pest resistance to bt crops is crucial, but it has been extremely difficult because bioassays usually cannot detect heterozygotes harboring one all ...200617066779

predicting unsaturated zone nitrogen mass balances in agricultural settings of the united states.unsaturated zone n fate and transport were evaluated at four sites to identify the predominant pathways of n cycling: an almond [prunus dulcis (mill.) d.a. webb] orchard and cornfield (zea mays l.) in the lower merced river study basin, california; and corn-soybean [glycine max (l.) merr.] rotations in study basins at maple creek, nebraska, and at morgan creek, maryland. we used inverse modeling with a new version of the root zone water quality model (rzwqm2) to estimate soil hydraulic and nitro ...201020400601
