D LITTLE ROCK, ARK.


on’t expect much change in soil moisture in the next few months, according to pro- jections by the National Weather Service


Climate Prediction Center. The three-month outlook for January-March


2012 shows an above-normal chance of pre- cipitation for northeastern Arkansas, includ- ing the only spot in the state that does not have a drought classification according to the Oct. 11 U.S. Drought Monitor Map. For the rest of the state, the January-March


outlook shows equal chances of above-, nor- mal or below-normal rainfall. The 12-month outlook for October-Decem-


ber 2012 shows equal chances for above-, normal or below-normal rainfall. The projec- tion maps


can be found at:


www.cpc.ncep.noaa.gov/products/predic- tions/long_range/seasonal.php?lead=13. The only bright spot in the drought picture


painted by the U.S. Drought Monitor is that the area of most intense drought – called ex- ceptional – shrank slightly from the previous week’s map, from 1.64 percent of the state’s area to 0.69 percent. Overall, 98.79 percent


of the state remained under drought, un- changed from the previous week. The Drought Monitor map is available at http://drought- monitor.unl.edu/DM_state.htm?AR,S. Summer-like heat returned – without the


humidity – last Sunday, with a new record high of 88 set in Little Rock and records tied in Monticello at 90 degrees and 91 at Russel- lville. Meanwhile, folks in western and southern


Arkansas continue to scan the skies for a hint of moisture. Much of the northern two-thirds of the state received rain on Oct. 12, but the droughted areas in the southwest received nary a drop. “We didn’t get enough rain to get you wet if


you were out in the rain,” said Joe Vestal, Lit- tle River extension staff chair for the Univer- sity of Arkansas Division of Agriculture. An approaching front was expected to bring


showers and possibly thunderstorms Monday night and ending Tuesday to a large part of Arkansas. Farmers planting winter wheat could use the moisture to germinate their seed and livestock producers need moisture for growth of fall or winter grazing.

Which Direction Are Herbicides Heading? CONTINUED FROM PAGE 12 Until the next novel herbicide comes out,


Riechers said you only have to look back at what happened with glyphosate to see how important it is to be a good steward by using herbicides in a sustainable, beneficial way. This article, “Evolution of Resistance to


Auxinic Herbicides: Historical Perspectives, Mechanisms of Resistance, and Implications


for Broadleaf Weed Management in Agro- nomic Crops,” was published in the Octo- ber-December 2011 issue of Weed Science. Authors include Dean Riechers of the Uni- versity of Illinois, Kevin Kelley of AgraServ, William Johnson of Purdue University, and Christopher Hall and Mithila Jugulam of the University of Guelph, Ontario, Canada. ∆
