Photo taken on April 27, 2018 at dryland wheat field in Wichita Co (Photo courtesy of Dr. Emi Kimura) As we received some rain last weekend, leaf rust started to show up on the flag leaf of already headed wheat. This field was about 4-5 weeks before harvesting depending on the weather, but the most fungicide (The list of fungicide available here) need to be applied prior to Feekes 10.5 (head emergence). Although flag leaf is very important and must be protected for maintaining grain yield and test weight,… Read More →
Photo taken on April 25, 2018 at dryland wheat field in Haskell co near Haskell, TX (Photo courtesy of Dr. Kimura) We were in the dryland wheat field in Haskell co checking on wheat at multiple maturity stages within one field. Wheat on the left side of photo is at Feekes stages 3-4, while wheat on the right side of photo is at Feekes stages 9-10.1 (emergence of flag leaves to right around boot stage). Mixed maturity stages of wheat development happened in this field probably due to… Read More →
Photo taken on April 17, 2018 at dryland wheat field in Wichita co near Burkburnett (Photo courtesy of Dr. Kimura) There were a few hours of freezing temperatures across the Rolling Plains of Texas on 4/7/2018. It normally takes 7-14 days until freeze damage starts showing up on wheat, so we went scouting for freeze injury damage during 4/13-4/18. Yes, we found some freeze damages on dryland and irrigated wheat, as you see in the photo. Symptoms of freeze injury include leaf burn, white seed heads, hook-like seed… Read More →
Photo taken on April 17, 2018 at dryland wheat field in Wichita co near Burkburnett (photo courtesy of Dr. Kimura) Much of our dryland wheat have been suffering from the a few months of dry weather although I have seen beautiful dryland wheat fields (these were probably planted at the PERFECT timing with good management practices). A question I received from wheat producers while we were scouting for freeze damage was about the yellow leaves at the bottom of the plant in the photo. It is likely that… Read More →
Photo taken on April 13, 2018 at irrigated and dryland wheat fields in Wilbarger co (photo courtesy of Dr. Kimura) Temperature fluctuations in the past few weeks are not helping wheat especially in dryland wheat. Photo above shows a clear comparison between stressed dryland wheat in the front and the irrigated healthy wheat. Wheat is a cool-season grass, which performs well in the cool temperatures and dislikes hot temperatures like we had in this week (4/9-4/13/2018). Actual temperatures around Vernon, TX were 82/29 on Monday, 75/37 on Tuesday,… Read More →
