As glyphosate-resistant weeds continue to be a major concern for soybean producers in Arkansas, many producers are relying on residual herbicides for control of problem weeds like Palmer amaranth. Metribuzin (Sencor/Lexone) is a PSII inhibitor (Group 5) herbicide that provides residual control of a number of annual grasses and broadleaf species. Metribuzin is especially

With the wet weather conditions we have been experiencing this spring, many soybean growers are concerned about the late start we have this year compared to the 2012 spring. Below is a study using historical data from the Soybean Research Verification Program (SRVP) to estimate optimum planting date to maximize soybean yield.

Each year, numerous soybean varieties are commercially available to growers in Arkansas. However, only a limited number of soybean varieties have been tested in Arkansas at April plantings. Yield performance in early (April) plantings varies according to location, adaptability to soils, relative maturity, lodging, shattering potential, disease and nematode resistance, as well as herbicide

Due to the increase of glyphosate-resistance in the Midsouth, producers have a renewed interest in the use of metribuzin as a part of their soybean weed control program. Metribuzin is a PSII inhibitor (Group 5) herbicide that provides residual control of an assortment of annual grasses and broadleaf weeds in soybean, including Palmer amaranth.

We are quickly approaching the end of the season on most of the fields in the verification program. We are still watching the later planted fields for insects and diseases. All the fields received rain from Isaac but only 1 suffered from the wind that accompanied the rain. We have had 2 of the fields harvested

Irrigation continues to be the main focus in the program, although we did catch a much needed rain on the fields in the River Valley and Central part of the State where we were limited on irrigation. Several of the fields in the program have either reached irrigation termination or are real close. Insect and

Rainfall during the week of July 10 gave some areas in the state a much needed break from irrigation, while some areas were not as lucky. Irrigation efforts have resumed keeping the crops moving forward. We had anticipated a large increase in bollworm numbers, but as of this date only one field in Cross
