WEED CONTROL RESULTS Mark VanGessel, Mark Isaacs, Quintin Johnson, Barbara Scott, Brian Hearn The purpose of this report is to present results and details of many of the 2003 weed control field trials conducted by Cooperative Extension at the University of Delaware. Results are summarized from data obtained at the Georgetown Research and Education Center and other test locations throughout the state. The results obtained and any conclusions stated are not published herein as recommended practices. The data in this report are especially intended for use by cooperators, commercial field workers, county agents, agricultural teachers, and researchers. They will also be of value to growers who are interested in following closely the development of new herbic ides and weed control systems. Treatments are listed by trade names to facilitate reading by non-technical people. No discrimination is intended and no endorsement is implied by the University of Delaware. Chemical index is cross-referenced by common and trade names. Many of the chemicals listed are actually a combination of two or more herbicides. Where this is the case, the name of the combination is followed by the herbicides that make up that combination. For example, Bicep II Magnum is a combination of s-metolachlor and atrazine, so Bicep II Magnum will be listed as such: Bicep II Magnum Premix ----s-metolachlor ----atrazine

5.5 L 2.4 3.1

2.2 lb ai/A 0.96 1.24

This quickly illustrates that Bicep II Magnum (5.5 L lb a.i./gal) contains 2.4 lb a.i./gal of s-metolachlor and 3.1 lb a.i./gal of atrazine, and that Bicep II Magnum applied at a rate of 2.2 lb a.i./A is equivalent to an application of s- metolachlor at 0.96 lb a.i./A and atrazine at 1.24 lb a.i./A. When analyzing the information in this report, we strongly urge you to read carefully the site description section of each study. We trust you will find the information in this report useful and accurate.

ACKNOWLEDGMENTS

The University of Delaware College of Agricultural Sciences and the Delaware Cooperative Extension gratefully acknowledge the farmers throughout the state that cooperated with us on several of our research projects. A special thanks is extended to all of the companies that contributed services and materials, and whose products have been evaluated in these tests. The University of Delaware and commercial firms have a common interest in providing farmers with improved weed control systems. Without the support of industry, this very important program could not be continued.

Trial Comments 05/28/03 Control of winter annuals was excellent for most treatments. Control was only fair for treatments 2, 3, and 7. Control was poor for treatment 9. Most of the winter annual vegetation consisted of field pansy, geranium, and primrose.

Trial Comments 05/28/03 Control of emerged weeds at time of herbicide application was excellent for all treatments. Yellow nutsedge control was not as good as all other species, and its control was consistent for all treatments. 09/06/03 Crabgrass control was similar for all treatments (poor). Common ragweed control was similar for all treatments (fair) except treatments 5 and 8 which were poor.

MAINTENANCE Field Prep./Maintenance: Force 3G at 5.5 lb/A in furrow and 18-46-0 (DAP) at 180 lb/A (32 lb N) 2x2 were applied at planting. The study was sidedressed with 30 gal/A 30% UAN solution (98 lb N) on 6-25-03. The corn crop was sprayed with Liberty in the end of August. A broadcast application of 416 lb/A of 24-14-7 was made on 7-30-03 for carryover crops.

Trial Comments 7-2-03 No injury was observed in any of the preemergence treatments. 7-9-03 Pitted Morningglory emergence appears to have been delayed and Common Ragweed control may be breaking in treatment #2. 7-25-03 Common Lambsquarters was not rated due to poor uniformity; however, Treatment 10 did not control CLQ. 8-14-03 The soybean canopy was nearly closed so morningglory was not rated by species. Pitted and Ivyleaf were present.
