I have observed a lot of emerged Palmer amaranth seedlings.

Early planted corn should be scouted at 4 weeks after planting to determine if a POST herbicide application is needed. A lot of no-till soybean fields need a burndown herbicide, and if Palmer amaranth is present in those fields, it makes things challenging. If the field was burned down earlier, and weeds have emerged since application, consider using Gramoxone (paraquat) to control emerged Palmer amaranth plants. Residual herbicides containing metribuzin or chlorimuron (unless the field has had history of poor control with ALS herbicides [Group 2]) will provide the greatest amount of help for burndown control of emerged Palmer amaranth in no-till soybean fields.

Growers and produce industry members are invited to Specca Farms on Wed. May 28th at 6:00 PM.

Join us for food and taste testing the latest Rutgers NJAES strawberry cultivar evaluations. Share a field tour and discussion of new strawberry cultivars. Includes growing systems and marketing tips to renew profitable strawberries with varieties bred for flavor and localized production adaptation.

Specca Farms is located 870 Jacksonville-Mt. Holly Road, (Burlington Co. Route 628), Springfield Twp. NJ 08505. For information call (732) 398-5262 or email Bill Hlubik hlubik@aesop.rutgers.edu or Peter Nitzsche nitzsche@aesop.rutgers.edu. Sponsored by Rutgers NJAES Cooperative Extension and partially supported by cooperating farmers, the Walmart Foundation, Univ. of Arkansas and NJ Small Fruits Council.

Available from the UD-REC website are weed management guides for assistance in weed control in corn, soybeans, or forages.
http://extension.udel.edu/ag/weed-science/weed-management-guides/

There is a separate guide for each commodity. The first half of the corn and soybean guides deal with soil-applied herbicides and the second half is for postemergence herbicides. These guides have pre-mixes and what is in the pre-mix, expanded weed control tables, information on application timing, comments for each of the herbicides, and much more. The forage guides cover alfalfa as well as grass forages.

Working with the Delaware Soybean Board and the United Soybean Board, a herbicide classification chart is available at:
http://extension.udel.edu/ag/weed-science/weed-management-guides/

This chart groups herbicides by mode of action and site group numbers that are printed on containers and labels. The chart is designed to help diversify herbicide use by rotating effective herbicides with different sites of action to delay the development of herbicide resistance. The chart provides the number of resistant weed species in the US to each site of action, which highlight those herbicides for which we already have wide-spread resistance.
