Competition of Transgenic Volunteer Corn with Soybean and the Effect on Western Corn Rootworm Emergence

Abstract: Glyphosate-resistant (GR) volunteer corn has emerged as a problematic weed in corn:soybean rotational systems, partly because of the rapid increase in adoption of corn hybrids that contain traits for both glyphosate and insect resistance. Volunteer GR corn can decrease soybean yields. The objectives of this study were to quantify the impact of volunteer corn on soybean growth and yield and determine how volunteer corn densities affect western corn rootworm (WCR) emergence. Volunteer corn seed was hand-planted … Show more

“…Increased adoption of glyphosate-resistant corn resulted in increasing issues of volunteer corn. Volunteer corn also plays a role in the survival and dispersal of corn rootworm and grey leaf spot disease; therefore, it limits the benefits of corn-soybean rotation and creates challenges for insect-resistance manage/ment (Marquardt et al, 2012b;Krupke et al, 2009;Shaw et al, 1978).…”

“…Volunteer corn is a competitive weed, as it grows taller than soybean, and like many other weeds, causes yield reduction by competing for light, space, nutrients, and moisture (Beckett & Stoller, 1988;Marquardt et al, 2012b). In addition, if corn volunteers remain in the field until maturity, corn seeds would contaminate the harvested soybean and reduce the market quality (Deen et al, 2006).…”

“…Thus, the degree of interference exerted by glyphosate tolerant corn volunteer plants can reach yield losses rates of 23% in corn, 18% in soybean, 19% in sugar beet and 8% in the production of cotton fibers (Thomas et al, 2007;Marquardt et al, 2012b;Kniss et al, 2012). Therefore, the use of tank mixtures with ACCase inhibitors graminicides can be an excellent alternative in desiccation handling and post-emergence of transgenic soybean (Deen et al, 2006;Maciel et al, 2013).…”

“…In addition, corn is a C4 plant, and it has a rather developed root system. It is likely that the impact caused by voluntary and/or spontaneous corn on soybeans is related to the direct competition for light, due to its higher height, causing a high suppression on the crop (Marquard et al, 2012).…”
