Legal comments and a second set of science comments are also being submitted. The references cited have been uploaded as supporting materials. The filenames for these documents match the citations in the text, and are all incorporated as (e.g. Benbrook 2012). Full citations are included at the end of each section. THE IMPACT OF DAS-40278-9 ON CORN HERBICIDE USE Summary of herbicide use Dow’s DAS-402787-9 corn is genetically engineered for resistance to 2,4-D and quizalofop, and if deregulated would be marketed with additional resistance to glyphosate and likely glufosinate – fostering greater use of three to four herbicide classes. APHIS must assess DAS-42078-9 as Dow intends it to be used, as a weed control system. DAS-40278-9 eliminates the risk of crop injury that currently limits 2,4-D use on corn, and is thus reasonably projected to trigger an up to 30-fold increase in the use of this toxic herbicide on corn, equivalent to a four-fold increase in overall agricultural use of 2,4-D, by the end of the decade. -
Post-Emergence Weed Control Options in Tree Nut Orchards
Post-emergence Weed Control Options in Tree Nut Orchards Marcelo L. Moretti1, Rolando Mejorado1, Seth Watkins1, David Doll2, and Bradley D. Hanson1 1University of California, Davis, Dept. of Plant Sciences,2Cooperative Extension Merced County [email protected] Herbicides are the primary means of vegetation management in tree nut orchards in California. Among registered herbicides, post-emergence (POST) materials, like glyphosate, are the most widely used in tree crops because of low cost and broad weed control spectrum. However, herbicide resistance has compromised the efficacy of POST only herbicide programs in many parts of the state. Most cases of resistance in orchards are glyphosate-resistant hairy fleabane, horseweed, ryegrass, and junglerice. To manage resistant weed species, pre-emergence (PRE) herbicides can be applied during winter before weeds emerge; however, PRE herbicide use can be limited by cost and the need for rainfall to incorporate them. Even when PRE herbicides are used, most orchards will need a POST treatment to control weed escapes and to prepare the orchard for harvest operations. One approach to optimize control of late emerging or glyphosate-resistant weeds is to use alternate herbicides, mixtures, rates, or more appropriate application timing. The objective of this project was to evaluate POST control of hairy fleabane and yellow nutsedge with different herbicides combinations. Methods Field experiments were conducted in a three year-old almond orchard infested with hairy fleabane and yellow nutsedge. The orchard was located in a sandy soil area in Merced County, and irrigated with solid set sprinklers. The area is known to be infested with glyphosate-resistant hairy fleabane. -
Safety and Efficacy of Postemergence Herbicides for Container-Grown Landscape Groundcovers

Connera, Chris Marble, and Annette Chandler Mid-Florida Research and Education Center, University of Florida, 2725 S. Binion Road, Apopka, Florida 32703, USA aEmail: [email protected] KeyWords: Landscape nursery, weed management, asiatic jasmine, Trachelospermum asiaticum ‘Minima’, perennial peanut, Arachis glabrata ‘Ecoturf’ SUMMARY Research was conducted to determine crop tolerance of asiatic jasmine (Trachelospermum asiaticum ‘Minima’) and perennial peanut (Arachis glabrata ‘Ecoturf’) to postemergence herbicides including bentazon, sulfentrazone, iron HEDTA, indaziflam (a preemergence herbicide), sulfosulfuron, and clopyralid. Efficacy of these herbicides was evaluated on flowering eclipta (Eclipta prostrata) and hairy beggarticks (Bidens pilosa). All herbicides with the exception of bentazon caused no significant damage to asiatic jasmine; injury resulting from bentazon was minimal. In perennial peanut, the highest injury was noted in plants treated with indaziflam, sulfosulfuron, or clopyralid, but injury was less than 30% and considered acceptable. All herbicides evaluated provided poor control of either weed species with the exception of clopyralid, which provided over 90% control of hairy beggarticks. Results indicate that several postemergence herbicides labeled for use in either nurseries or landscapes could be used to manage weeds in asiatic jasmine or perennial peanut groundcovers but further testing is needed. 1 2 INTRODUCTION Turfgrass is the most widely planted irrigated crop in the United States and occupies the vast majority of most residential and commercial landscapes in Florida (NTRI, 2003). However, the common mantra of landscape design is “right plant right place”. In many neighborhoods, parks, and other areas containing significant tree canopy, turfgrass is not suitable due to limited sunlight. -
