چکیده
On June 19, 2003, the Center for Science in the Public Interest (CSPI) issued “Planting Trouble: Are Farmers Squandering Bt Corn Technology?” That report presented data from the United States Department of Agriculture (USDA) that found significant noncompliance by farmers in Iowa (IA), Minnesota (MN) and Nebraska (NE) with the Environmental Protection Agency’s (EPA) refuge requirements for corn engineered with genes from the Bacillus thuringiensis (Bt) bacterium. To ensure insect susceptibility and to protect the environment, EPA requires Bt corn farmers to: (1) plant a 20 percent non-Bt corn refuge in the Corn-Belt states, and (2) plant the refuge within one-half mile of the Bt corn.

متن کاملOnion thrips (Thrips tabaci (Thysanoptera: Thripidae)) in cabbage on Prince Edward Island: observations on planting date and variety choice
Onion thrips (Thrips tabaci Lindeman (Thysanoptera: Thripidae)) can be a pest in organic onion production on Prince Edward Island. This study was to examine the effect of planting time and variety on infestation levels and damage by onion thrips on cabbage (Brassicae oleracea capitala (L.)). A field site was planted with 2 main and 8 lesser varieties of cabbage over 4 planting dates. Some varie...
متن کاملEffect of planting depth on growth of open-rooted Pinus elliottii and Pinus taeda seedlings in the United States
Three studies in the Coastal Plain of Georgia were remeasured 7 or 8 years after planting to determine the effects of planting depth on field performance of open-rooted seedlings [root-collar diameter (RCD) ≥ 5 mm]. Average planting depth (i.e. shoot height before planting minus shoot height above ground after planting) for machine planted P. elliottii was 14 cm while hand-planted P. taeda seed...
