WEED CONTROL RESULTS Mark VanGessel, Mark Isaacs, Quintin Johnson,

Barbara Scott, Jeff Wright

The purpose of this report is to present results and details of many of the 2007 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 herbicides 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 5.5 L 2.2 lb ai/A ----s-metolachlor 2.4 0.96 ----atrazine 3.1 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.

Trial Comments 5-23-07: Control of summer annual weeds was better in the Gramoxone treated plots than with glyphosate treatments (regardless of tank-mix partner). Resolve plus 2,4-D was very poor for barley control, as a result emergence of otherspecies was very poor.

Trial Comments 11/30/06 - Aim caused initial leaf burn but plants quickly outgrew it and no burn seen now. 12/20/06 - No stunting observed with any treatment. 05/01/07 - Density of jagged chickweed, common chickweed, and corn speedwell was low and inconsistent. Thus, it was difficult to rate percent control of these species, rather presence or absence was noted. If there were plants present, it was rated as 100, if weeds were absent it was rated 0. 05/01/07 - Plots 120, 210, 218 --- 1 row poor stand 06/12/07 - Treatment 14 had less vigorous wheat plants (about 20%) and many heads showing symptoms of phenoxy injury.

Trial Comments 05/02/07 - Aim provided fair control of corn speedwell and field pansy; poor control of mouse-ear chickweed; and no control of cress, horseweed, wild garlic, and wooly plantain. Low rate of Harmony Extra provided excellent control of cress and horseweed; good control of common chickweed; fair to good of wild garlic; poor to fair for field pansy; and poor control of corn speedwell and mouse-ear chickweed. No control of wooly plantain. Higer rate of Harmony Extra was similiar to lower rate, except mouse-ear chickweed was fair. Harmony Extra plus 2,4-D was similar to Harmony Extra alone except wooly plantain control was fair to good.

Trial Comments 12/20/06 - Good to excellent weed control with all treatments. 3/14/07 - Excellent control of all winter annuals with all treatments. Most prevalent species are Field Pansy and Horseweed. 5/25/07 - Annual grasses werenoted as present (1) or absent (0). The summer annual species were common lambsquarters, common ragweed, and pigweed. No summer annual weeds were observed in the untreated check due to weed competition. Ragweed was the only species observed in the plots with Canopy EX.

Trial Comments 06-12-07: Treatments with poor horseweed control had stunted soybean plants due to moisture stress and this also has impacted weed emergence. Ladysthumb and common ragweed density was sparse so only presence (1) or absence (0) was noted. Annual grass is a mixture of fall panicuma and large crabgrass. The soybeans in this trial suffered moderate deer damage.

Trial Comments 8/15/07 - Rated at 3rd true leaf development. plot 310 (outlook trt) was only plot showing some chlorosis. 3rd rep in lower ground - a little more stunting from additional water. see data collection sheet for notes on poor cuke emergence and spacing of gaps in rows 2 & 3. Weeds emerging: ivy, pigweed, lg crabgr, some carpet. 8/28/07 - goosegrass and fall panicum densities fall in the 2nd and 3rd rep - 2-3 plants per check!! 9/4/07 - downy mildew on cukes - difficult to rate chlorosis, but appears minimal (0-15) at this time. 10/8/07 - Weed control was good through harvest for treatments 6 through 10. Weed control was fair for treatment 12. All other treatments had poor to no weed control.

Trial Comments 3-14-05 The orchardgrass was dormant. Fall regrowth was approximately 12 inches, and 80 to 90 percent of the leaf material left from the fall was winter-killed. Mouseear chickweed was scattered; burndown ratings will not be possible, but residual ratings may. 3-22-07 Leaf burn ratings are for leaf material that was previously green. Prowl treatments had some very slight leaf twisting (<5%). 4-26-07 Chlorosis for Roundup treatments is whitening.

Trial Comments 4-10-07 All treatments except #4 killed the field pansy flowers. 4-25-07 Redstem filaree was not consistent enough to rate. In individual neither herbicide at the x-rate or 2x-rate provided adequate control, although the Roundup treatments showed more activity (stunting) than the Gramoxone treatments. Roundup at the 4x-rate provided 100% control of redstem filaree in plot 307. Unable to determine control for 4x-rate of Gramoxone from any of the reps.

University of Delaware 2/28/07 - Soil cores removed for bioassay in greenhouse (these plots were 25' in length and cores were pulled at 11,13,15,17'). 4 samples were removed from the middle and the side of each plot at depths of 0-2, 2-4 and 4-8 inches and respective depths and loci were combined. Soil stored at 44 degrees F for 48 hours. Soil was stirred and weighed, each sample was standardized at 525 grams for 0-2 and 2-4", and 1,225 grams for 4-8" (note that this included moisture). Soil was distributed over a moistened, compacted bed of potting soil on 3/2/07and then a light layer (~1/4 ") of moistened potting soil placed evenly over the top for moisture retention. temps in gh at this time range from 55 to 101 degrees F. (trts were no basamid;basamid rototilled; basamid no roto all under plastic and no plastic untrtd) Ratings: 5/23/07: Plant health measured on scale from 0-5 - 5=exc, 4=good, 3=fair, 2=poor, 1 dying, 0=majority plot dead. ??Fall plastic ? of > moisture levels ? > organic matter (dead composted grass). Injury was either leaf curl, stem girdling, yellowing older leaves (lack of Nitrogen/senesence) 5/30/07: weed pressure under / through holes in plastic where melons planted - 0=none to light, 1=moderate, 2=heavy pressure. 6/25/07: plant health based on plant vigor / size - NOT on fusarium which exists with scattered plants. 7/3/07: Kate counted # of plants per plot with fusarium. 7/20/07: 1st harvest early - fusarium knocking down plants - tendrils drying prematurely health of overall treatments noted as # of dead or severely wilted plants. plots 104, 205, 403, 401, 505 particularly hard hit with Fusarium (trt 5 esp hard hit). Marketable yield for this harv was considered 12 lbs or greater.

LQ not prevalent except at west end; plot 111 - stinkgrass heavy; plot 210 -dir-seeded pumpkin injury slightly higher than norm ? water?; plots 213,214,303 yellowing - nitrogen difficiency?; plot 308 - goosegrass ext heavy; plot 313 - goose- and stinkgrass heavy. 9/10/07 - Volunteer rye - heavy population (8 inches tall) in rye cover trt, all reps. Conventional and stale seedbed trtsin rep 2 have more open space and less grass control due to dieback of the vines (powdery mildew likely). Fall panicum comes in heavy on 3rd rep replacing crab and goose as predominant grass.
