Late-instar European corn borer (Lepidoptera: Crambidae) tunneling and survival in transgenic corn hybrids.
Field studies were conducted in 1996 and 1997 to determine injury by and survival of late-instar European corn borer, Ostrinia nubilalis (Hübner), on genetically altered Bacillus thuringiensis Berliner corn, Zea mays L. Cry1Ab events 176, Bt11, MON810, and MON802; Cry1Ac event DBT418; and Cry9C event CBH351 were evaluated. Plants of each corn hybrid were manually infested with two third-, fourt...
متن کاملSelecting Corn Hybrids
Corn is physiologically mature when kernels reach maximum dry weight and are safe from frost. All milky fluid disappears from the kernel, and the black layer, a dark layer of cells, forms near the tip of mature kernels. Most hybrids adapted to Wisconsin reach this stage when kernel moisture decreases to 30–32%, but it may not occur until moisture content decreases to 28% for some early hybrids....
متن کاملRanking Corn Silage Hybrids
Corn hybrids for silage vary in yield and several quality traits that affect farm profitability, which is the prime criterion on which hybrids should be ranked. The partial budget approach is the only way to rank corn hybrids for silage for individual farms according to their effects on farm profits. Partial budgets consider only those costs and returns that change in response to the corn hybri...
متن کاملOn-Farm Corn Rootworm Trials
Introduction There are several methods to manage corn rootworms, including crop rotation, rootworm insecticides, and corn rootworm (CRW) transgenic traits. The use of CRW transgenic traits in corn hybrids has allowed farmers to manage CRW without using soil-applied insecticides. However, rootworm populations resistant to the transgenic traits have been confirmed in Iowa, leading some farmers to...
متن کاملEffect of nitrogen consumption management on morphophysiological traits, yield and yield components of corn hybrids (Zea mays L.)
In order to investigate the effect of nitrogen management on morphophysiological traits, yield and yield components of corn hybrids, the present experiment was carried out in a split plots arrangement in a randomized complete blocks design with three replications in a field located in Ahvaz city during the crop year 2016-2017. Experimental treatments consisted of nitrogen fertilizer management ...
