Harvesting Cost Estimates
Author: Scott Stiles, Extension Economist

For the week ending September 3, USDA estimated that Arkansas’ corn acreage was 46% harvested. Rice and soybeans were 18% and 7% harvested respectively.  Currently the state’s harvest pace for corn and rice is running 5 percentage points behind the 5-year average.

Times are tough-scrutinize every input choice
Author: Gus Lorenz, Extension Entomologist

By Gus Lorenz, Extension Entomologist Seems like most everybody who retails ag inputs is offering products that they profess will boost yields, even make ‘em skyrocket. Only problem is, claims often aren’t backed up with unbiased data to prove that these materials provide growers with a return on investment–that ROI that should guide every decision. […]

Determining when to harvest your peanut crop
Author: Travis Faske, Extension Plant Pathologist

By Travis Faske, Extension Plant Pathologist Unlike other row crops, peanuts are not terminated by shutting off the water but rather by digging and inverting the crop (Fig. 1). Currently, there are a few fields that are being dug across the state, but determining when to dig is an important decision that should not be […]

Peanut Disease Update: Sclerotinia blight caused by Sclerotinia sclerotiorum confirmed in Arkansas

Sclerotinia blight caused by Sclerotinia sclerotiorum was confirmed earlier this month in a commercial peanut field near Pocahontas. Sclerotinia blight symptoms were recognized by Gordon Drennan with the Clint William Co. and confirmed by extension plant pathologist on a runner peanut cv. Florun107.

Peanut producers: Spotting leaf spot diseases and fungicide timing for southern blight
Author: Travis Faske, Extension Plant Pathologist

Though it is very common to find spots on peanut leaves in Arkansas, the disease called early leaf spot (ELS) of peanut (and late leaf spot of peanut) has yet to be confirmed in the state. Herbicide injury is most commonly mistaken for ELS (Figure 1). Early leaf spot is caused by the fungus Cercosproa […]

Preventing Damage From Insects in Stored Wheat
Author: Glenn Studebaker, Extension Entomologist

Wheat harvest is underway and some growers will be storing their harvest on farm in bins for an extended period of time. Recent heavy rains have kept some growers out of the field and now would be an excellent time to prepare bins for storage. Wheat is particularly susceptible to stored grain insects because it […]

Pop up fertilizers: What you need to know
Author: Leo Espinoza, Associate Professor & Extension Soil Scientist

Pop up fertilizers are commonly used in some corn growing areas in the country.  The practice consists of applying a few pounds of nutrients with the seed at planting.  Planters are retrofitted with commercially available attachments that accurately deliver the desired volume of liquid fertilizer.  This practice should not be confused with “starter fertilizers” which […]

Managing bacterial panicle blight: Research gives helpful clues
Author: Yeshi Wamishe, Extension Rice Plant Pathologist

“Be proactive” – this is the best approach to beat the unexpected effects of sporadic diseases such as bacterial panicle blight (BPB) of rice.  Looking back, the rice yield and quality losses we had in 2010 and 2011 were enormous.  Having most of the conventional varieties still susceptible to BPB and with no chemical options […]

Are you maximizing control with your herbicide application?
Author: Tom Barber, Extension Weed Scientist

This is an interesting time in Arkansas agriculture as new technologies are on the horizon in many crops and resistant weeds are becoming more prevalent in all crops and across multiple modes of action.  We have screened multiple samples of barnyardgrass that contain 3-way resistance to Propanil, Facet, and Newpath (ALS) chemistry.  Also annual and […]
