Spartan 4F receives Section 18 label for Michigan strawberries for 2008
Editor’s note: This article is from the archives of the MSU Crop Advisory Team Alerts. Check the label of any pesticide referenced to ensure your use is included.
On April 21, the US EPA issued a Section 18 label (specific exemption) for use of Spartan 4F on strawberries in Michigan for 2008. The label is similar to the Section 18 labels we have had for the past several years. A maximum of 1,000 acres of strawberries may be treated with Spartan in Michigan in 2008. The label is effective June 25 to December 15, 2008.
Spartan 4F may be applied to strawberries at renovation or after the plants have gone dormant late in the season. The primary target weeds are mayweed chamomile, puncturevine, redroot pigweed, common groundsel, field pansy, white campion and yellow woodsorrel. Spartan will control many other broadleaves and grasses as well.
Four to eight fluid ounces of Spartan 4F may be applied in any one application. A maximum of 12 fluid ounces may be applied per year. There is a 70-day preharvest interval (PHI), but this should not affect Michigan production, since Spartan is applied after harvest is finished for the year.
Spartan may be applied in tank mixes with Sinbar and postemergence herbicides such as 2,4-D, Stinger, Poast or SelectMax. The postemergence herbicides will kill emerged weeds and the residual herbicides will maintain weed control until fall frost.
Copies of the label will be available from chemical dealers and suppliers. As soon as we receive a copy, we will post it on the MSU vegetable website:www.veginfo.msu.edu.
This is the seventh year that Michigan has had a Spartan Section 18 label for strawberry. We hope to have a tolerance and label soon. To continue the Section 18 process, the Michigan Department of Agriculture must interview several growers who use it and obtain their reports on the effectiveness of the use. We encourage growers to cooperate with MDA personnel if and when you are called for a report. Growers for the interviews are chosen randomly from users around the state.
