FHB Update from KS, 03/24/17

The risk of Fusarium head blight in Kansas is low. The wheat crop is most vulnerable to Fusarium infection at the flowering growth stage or the early stages of grain development. The critical growth stages for Fusarium head blight will occur in approximately three weeks. Dry weather conditions are holding most leaf diseases at low levels, but recent rains may stimulate some activity.

FHB Update from US, 03/24/17

Welcome to the Fusarium Head Blight Prediction Center. The current focus of the prediction models is on the Southern US where the wheat is approaching or already at the flowering growth stages that are most vulnerable to Fusarium infection. The current risk map indicates that the chance of severe Fusarium Head Bight is low in most areas of the Southern US but there is a section of southern Louisiana that is at moderate or high risk for disease. Growers in this area should check with their local extension specialists or crop consultants for additional evaluations of disease risk.

The northern portion of the risk map is gray because the wheat crop these areas is not at growth stages that are vulnerable to Fusarium infection. The system will automatically adjust to show these northern regions as the season progresses.

FHB Update from AL, 03/24/17

Scab risk for Baldwin Co. in SW AL is medium while the remainder of the state is at a low risk for scab development in wheat. Very early varieties are heading in that area of Alabama and if the heads were not damaged by last week’s freeze, need to be treated with a recommended fungicide for scab. However, rain is predicted this weekend and most of next week, so the scab risk will likely increase. Otherwise, the early varieties in the wheat variety trial at the Gulf Coast Research and Extension Center and Brewton Agricultural Research Center were largely free of foliar diseases. However, many of the mid- and late-maturing varieties in that trial have already suffered heavy leaf rust damage, so growers and consultants in that area need to scout for leaf rust and apply a fungicide at flag leaf and possibly flowering to control this disease.

FHB Update from KS, 03/16/17

The wheat crop is still at the pre-jointing stages of growth and is not vulnerable to Fusarium infection. Dry weather conditions are holding most leaf diseases at low levels.

FHB Update from US, 03/16/17

Welcome to the Fusarium Head Blight Prediction Center. The system is now active for the 2017 growing season. The current focus of the prediction models is on the Southern US where the wheat is approaching or already at the flowering growth stages that are most vulnerable to Fusarium infection. The current risk map indicates that the chance of severe Fusarium Head Bight is low in most areas of the Southern US.

The northern portion of the risk map is gray because the wheat crop these areas is not at growth stages that are vulnerable to Fusarium infection. The system will automatically adjust to show these northern regions as the season progresses.

FHB Update from US, 03/06/17

Welcome to the Fusarium Head Blight Prediction Center. The system is now active for the 2017 growing season. The current focus of the prediction models is on the Southern US. The crop is generally considered ahead of schedule this year and some fields in southern LA and MS may be approaching or already at the growth that are most vulnerable to Fusarium infection. The current risk map indicates that the chance of severe Fusarium Head Bight is low in most areas of the Southern US.

FHB Update from US, 08/23/16

The wheat in the US is past the growth stages that are most vulnerable to Fusarium Head Blight and the prediction system is inactive. The information from the 2016 season is still available and can be accessed by selecting desired assessment dates from the menu options on the left of the map. The FHB Prediction Center will resume normal activity in the spring of 2017.

FHB Update from US, 08/03/16

Most wheat in the US is now past the growth stages that are vulnerable to Fusarium Head Blight. There are still a few active areas of North Dakota and Minnesota that indicate moderate or high levels of disease risk. The gray areas of the map are likely past the critical stages of growth for Fusarium infection.

FHB Update from ND, 07/14/16

There are several late-seeded spring wheat and Durum fields in ND that will be approaching flowering soon. Frequent rain and prolonged periods of high humidity over the past week have elevated scab risk for susceptible, moderately susceptible and moderately resistant varieties. High scab risk exists in the northern third of the state and moderate scab risk exists for a large area in the eastern half of the state. Scab risk is likely to remain moderate to high as more rain and high humidity is projected to occur in the next few days.
