Introduction

Louisiana can be divided into several areas based on cropping systems, climatic conditions, soil types, and pH. These factors are important in selecting specific herbicides and rates and can directly affect herbicide efficacy, crop safety, and injury to rotational crops. South Louisiana has an abundance of weed species, some not commonly found in other areas of the state. Our climatic conditions are favorable for prolific weed growth and subsequent competition with crops. Weeds can be controlled with mechanical cultivation, crop rotation, and herbicides. Louisiana producers currently use all these methods, but herbicides serve as the foundation for successful weed control programs. Steady progress has been made over the last 25 years in the development of effective herbicides with crop safety. Research and extension personnel with the LSU AgCenter work cooperatively with agri-chemical companies to evaluate new herbicides for weed control and crop tolerance as well as their effect on rotational crops.

This progress report summarizes weed research conducted in sugarcane, soybeans, and corn during the 2002 growing season. Results of herbicide efficacy and crop tolerance studies are presented. Results are preliminary since evaluation of some of the herbicides is limited. Data presented in this report should not be considered as an endorsement or recommendation of any herbicide and should not be reproduced without permission. Registration by the Environmental Protection Agency is required before any herbicide can be legally used.

Rainfall data for the 2002 growing season are shown in Table 1 and 2. Herbicides and adjuvants evaluated are presented in Table 3. Selected weed areas at the Ben Hur Research Farm, the St. Gabriel Research Station, and at several off-station sites have been managed to encourage uniform weed populations. Weed species evaluated for control are presented in Table 4. Specific information on location, soil type, variety, row spacing, treatment date, sprayer type, etc. for all experiments along with brief comments are presented followed by a table of experimental results. Data were summarized and statistically analyzed with the Agriculture Research Manager (ARM) by Gylling Data Management, Inc., Brookings, South Dakota. Control and crop injury ratings for all experiments are based on a scale of 0 to 100%, where 0 equals no control or crop injury and 100% equals complete control or crop injury. Injury ratings were based on chlorosis, necrosis, and stand and height reductions. Where appropriate, crop yields were obtained. Soybean and corn yields were adjusted to 13 and 12% moisture, respectively. Miscellaneous abbreviations used in this report are shown in Table 5.

Griffin, Department of Agronomy, 104 Sturgis Hall, Baton Rouge, LA 70803, (225) 578-1768, or by e-mail at [email protected].

Nufarm Glyphosate Evauation Test Project Code: 02SB02JG _____________________________________________________________________________________________ Comments: The intent of this study was to evaluate various glyphosate formulations applied at rates equivalent to 16 and 24 oz/A of Roundup Ultra and 12.8 and 19.2 oz/A of Roundup UltraMax. Weeds were large at application to allow for relative comparisons among the formulations and rates. The NUP 0532 formulation was not sent to us so the control values are noted as zero (no control). Weed control ratings were made on June 18 (7 days after treatment) and on July 2 (21 days after treatment). No differences in control of hemp sesbania (SEBEX) or pitted morningglory (IPOLA) were observed among the glyphosate formulations or rates at either rating date. Soybean injury was not observed. _____________________________________________________________________________________________

The tilled area was then re-tilled on June 19, July 16 and August 14. At each of these dates, the no-till area was sprayed with Liberty at 40 oz/A to control any emerged red morningglory. Prior to tillage or liberty application red morningglory population was determined. _____________________________________________________________________________________________
