Disease damages wheat roots, thwarts water uptake
March 02, 2006Alterations in irrigation schedules may be needed when wheat streak mosaic infection is suspected in winter wheat crops, according to a Texas Agricultural Experiment Station researcher in Amarillo.
Drought this winter has prompted more irrigation of wheat than normal; however, wheat streak mosaic is also being detected, said Jacob Price, a graduate student and diagnostic technician for the Experiment Station's plant pathology department.
Wheat streak mosaic, the most common wheat disease in the Texas Panhandle, is a problem throughout many wheat production areas, Price said. The disease is spread by the wheat curl mite and currently no pesticides can control the mite, he said.
In the High Plains, wheat is frequently irrigated and grown for both grazing and grain production, he said. It is already known the disease has a negative impact on plant development and forage yield.
Now Price is trying to get to the "root" of the problem. He wants to determine what effect the stunted root systems of infected plants have on their uptake of irrigation water and whether different levels of irrigation make a difference on the plants' growth and yields.
"We're trying to determine if it is worth irrigating at all," he said.
"I hope this research will develop recommendations on irrigation for infected wheat plants."
Samples are already being submitted this year with the yellowing, stunted symptoms of wheat streak mosaic to Jacobs. After making a diagnosis, he sends the information to the Plant Diagnostic Information System, a wide-scale information system used by many agricultural centers.
"What I've seen in my experiments so far is it (the disease) damages root growth," he said. "Once infected, the roots don't grow anymore. If they don't develop, they can't take up water efficiently and expensive irrigation water would be wasted."
Producers normally irrigate using the guidance of the Texas High Plains Evapotransporation network, Price said. The network collects weather data from various stations and uses it to estimate the daily water use of a crop.
By determining how much water the infected plants are actually taking up, he said he hopes to help producers save water and money and still maintain the best possible yields under the diseased scenario.
His study is only a year old, but Price intends to replicated it two more years both in the greenhouse and in the field. The greenhouse study looks primarily at root mass, while the field study tests plant production and yield, he said. He is using a neutron depth moisture gauge to monitor water uptake.
"When it starts warming up and the wheat starts growing, that's when we'll see more yellowing and we'll get a lot more samples to test," he said.
"I'm concerned since we've had so much drought and it's so expensive to irrigate this year," Price said. "Water-use efficiency is going to be key."

White Ink, Black Ink by Wheat With their shimmering new album, Taunton' MA's Wheat is back from an extended period of musical hibernation. Following the critical success of their first albums, 1998's "Medeiros" and 1999's "Hope And Adams", the band released their major label debut in 2003, followed a few years later by a home-recorded album; the latter allowing them to reconnect with the process of musical experimentation and improvisation. This, their latest release, contains some of the most concise, well-written songs of the band's career, and also features some of their most intriguing musical explorations. |

Organic Hard Red Wheat Seed- 35 Lbs- Plant & Grow Wheatgrass, Grind to Make Flour & Bread, Emergency Food Storage Seeds by Living Whole Foods All Wheat is Not Equal. We have had the experience of growing wheatgrass and being in the commercial wheatgrass business over the last 14 years. During that time we have experienced many different kinds of wheat. We have used wheat from Texas, Utah, Montana, California, and Israel both organic and non organic. There are two kinds of wheat one can buy: chemical free and certified organic. Most wheat is chemical free in that the farmer might or might not use an herbicide to control the weeds in his fields. If he uses chemicals on the wheat, it will cause a distinct taste in the bread thus no chemicals are used on the wheat itself. Then there is certified organic: Certified organic is the same as chemical free except the wheat is grown by farmers who have not used chemicals on their land for... |

Medeiros/Hope And Adams Re-issue by Wheat Specially priced deluxe double CD re-issue of two '90s indie rock classics plus a bonus third CD of rarities. Massachusetts' Wheat has deliberately avoided the spotlight over their four album career. 1998's "Medeiros" was praised for its air of serene resignation, its aquatic wash of keyboards, slowly warping guitar chords, and gently urgent rhythms. "Hope And Adams" is now regarded as a touchstone of the late '90s indie rock scene. Look for their next album, "White Ink, Black Ink", in May. |
