Wheat disease pressure still low
Author: Gene Milus, Professor, Plant Pathology-Wheat

The incidence and severity of wheat diseases remains low across all of Arkansas. Although recent rains coincided with flowering in northern Arkansas, the risk of Fusarium head blight (scab) remains low because weather conditions earlier in the season were not favorable for development of the fungal spores necessary to infect wheat. There is no need […]

Wheat diseases mostly a no-show so far
Author: Gene Milus, Professor, Plant Pathology-Wheat

Whether measured by the calendar or by wheat growth stage, the level of diseases in wheat fields across Arkansas appears to be unusually low. So far, only barley yellow dwarf has been confirmed from plots at Marianna. The probability of a stripe rust epidemic this year is extremely low. Given this lack of foliar fungal […]

Wheat Growers Encouraged to Respond to National Survey on Wheat Scab
Author: Gene Milus, Professor, Plant Pathology-Wheat

National survey on wheat and barley head scab This spring, about 16,500 wheat and barley growers in 17 states (450 in Arkansas) will receive a questionnaire on Fusarium head blight (scab) from the National Agricultural Statistics Service (NASS). Scab is a fungal disease that infects the heads of small grain plants. It can be severely […]

Wheat after corn or sorghum leads to higher risk for scab
Author: Gene Milus, Professor, Plant Pathology-Wheat

Fusarium head blight or scab disease of wheat has been a minor problem in Arkansas since 1991 when scab contributed to the record low state average yield of 22 bushels / acre. Given that there are more than one million acres of corn and sorghum in Arkansas this year, a significant portion this fall’s wheat […]

Low risk for Fusarium head blight (scab) in wheat
Author: Gene Milus, Professor, Plant Pathology-Wheat

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 application […]

Wheat disease update – May 3, 2013
Author: Gene Milus, Professor, Plant Pathology-Wheat

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 or […]

Wheat Disease Update, 26 April 2013
Author: Gene Milus, Professor, Plant Pathology-Wheat

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 on lower leaves. At Rohwer, maturities ranged from boot to past flowering. Stripe rust did not increase much since last week, and the stripe rust fungus […]

Wheat Disease Update, 18 April 2013
Author: Gene Milus, Professor, Plant Pathology-Wheat

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 applied or […]

Update on wheat stripe rust, March 15
Author: Gene Milus, Professor, Plant Pathology-Wheat

Based on observations from plots at the Rohwer Experiment Station in Desha County, Beretta, Ricochet and Progeny 185 were the most susceptible varieties to stripe rust and had hot spots with numerous infected leaves. Scattered leaves with stripe rust were found on 26R20, Arcadia, Coker 9553, Harrison, Progeny 308, and Terral 8861. In previous years, […]

Decision time near for early-season stripe rust management
Author: Gene Milus, Professor, Plant Pathology-Wheat

The plants in the picture below were from one of the stripe rust hot spots found in a Lonoke County wheat field in December. The plants were dug up on January 9 and placed in a growth chamber for 2 weeks at a cool temperature favorable for stripe rust. The lower leaves that had stripe […]
