May 16, 2013 No. 2013-8 Dr. Jarrod Hardke Dr. Bob Scott, and Dr. Yeshi Wamishe Planting Forecast This has been a week for progress up and down the state. The last rice planting progress estimate came in at 60% on Monday, but I have a strong feeling that we’ll be in the 80% range Continue reading Arkansas Rice Update 5-16-13 Stressed rice seedlings Arkansas producers have been struggling to plant rice in the cold and wet conditions of 2013. As of the second week of May, the oldest rice I have seen was at the 3-leaf stage. I planted my first field plots at the Rice Research and Extension Center on March 19, Continue reading Diseases may be a concern in late planted rice Wheat south of I-40 is mostly past flowering and beyond the most susceptible growth stage for infection. Although some wheat in northeast Arkansas is still at the critical flowering stage, the risk for scab is forecast to be low based on weather variables. There does not appear to be a need for a fungicide Continue reading Low risk for Fusarium head blight (scab) in wheat May 3, 2013 No. 2013-6 Dr. Jarrod Hardke and Dr. Yeshi Wamishe Planting Forecast Rain is a four-letter word these days, if you catch my drift. Quite frankly I’m getting tired of writing it. I don’t want to talk too bad about it or it might up and disappear when we really need it. Continue reading Arkansas Rice Update 5-3-13 Stripe rust is still increasing on susceptible varieties at locations where it blew in during the spring. The most susceptible varieties are Arcadia, Progeny 117, Progeny 185, and USG 3993. Except for a few fields, stripe rust does not appear to be having a significant impact on yield because of adult-plant resistance and one Continue reading Wheat disease update – May 3, 2013 April 25, 2013 No. 2013-5 Dr. Jarrod Hardke, Dr. Yeshi Wamishe, and Dr. Paul Counce Planting Forecast Actual progress was actually being made. It wasn’t necessarily fast but it definitely seemed furious. The early part of the week was certainly prime time. Wednesday’s rainfall slowed some more than others. A few people were working Continue reading Arkansas Rice Update 4-25-13
The black fruiting bodies associated with stripe rust lesions are telia of the stripe rust fungus and signal and end of the stripe rust epidemic. I evaluated plots near Kibler, Rohwer, and Mariana on 24-25 April. At Kibler, maturities ranged from early boot to flowering, and only low levels of leaf blotch were found Continue reading Wheat Disease Update, 26 April 2013 April 19, 2013 No. 2013-4 Dr. Jarrod Hardke and Dr. Yeshi Wamishe Planting Forecast “The rain, boss. The rain.” It’s not exactly Fantasy Island these days. I feel like a broken record, but it’s raining again. And it’s going to rain again. We reportedly received one to three inches across eastern Arkansas from yesterday’s Continue reading Arkansas Rice Update 4-19-13 Unlike last week’s report that was based on emails and phone calls, this report is based on observations in plots at Rohwer, Keiser and Newport and fields along the way. Stripe rust was serious only in areas where it overwintered on varieties with low levels of adult-plant resistance and either no fungicide was Continue reading Wheat Disease Update, 18 April 2013 April 10, 2013 No. 2013-3 Dr. Jarrod Hardke, Dr. Bob Scott, and Dr. Yeshi Wamishe Planting Forecast Another round of rain and wind appears to be next up for a spring that has certainly made a 180 degree turn from 2012. Current estimates released on Monday say that 4% of rice acreage has been Continue reading Arkansas Rice Update 4-10-13 |
