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.

FHB Update from ND, 07/06/16

Hard red spring wheat in northern North Dakota and durum in northwestern North Dakota are approaching flowering. Frequent rain events and high relative humidity have created a high scab risk for susceptible varieties in northwestern ND and areas along the Canadian border. For moderately susceptible varieties, a pocket of high risk exists in northwestern North Dakota and moderate risk in areas along the Canadian border. Producers in moderate to high risk areas are encouraged to apply a triazole fungicide (Prosaro, Caramba) at early-flowering for scab management.

FHB Update from SD, 07/05/16

Spring wheat in South Dakota is past the critical stage for scab development. It has been dry throughout the state and the fields scouted in the past week had trace levels scab. This may be a year of light scab in South Dakota

FHB Update from ND, 06/29/16

A significant portion of the small grains in the southern half of North Dakota are entering stages of kernel development. In the northern tier of North Dakota, barley is heading and hard red spring wheat and durum are in the flowering stages. Rain events over the past week have contributed to moderate to high scab risk for susceptible varieties in northwest counties of Divide, Burke, Williams and Mountrail and northeast counties of Cavalier and Pembina. For moderately susceptible varieties, a pocket of moderate risk exists for the northwest counties. As a reminder, scab resistance in durum is not equal to scab resistance in hard red spring wheat. In other words, a moderately resistant durum is approximately equivalent to a moderately susceptible spring wheat variety. Therefore, when using the models for durum scab risk, make the appropriate adjustments in regards to variety susceptibility.

FHB Update from US, 06/27/16

Welcome to the Fusarium Head Blight Prediction Center. The risk maps are best viewed with firefox, chrome, or safari web browsers. The current focus of the prediction effort is on the spring wheat crop in the northern Great Plains This wheat should be at or near flowering and early stages of grain fill in some parts of ND, SD and MN. The crop is most vulnerable to Fusarium infection at these growth stages. The risk of severe FHB is currently low in most areas of the northern plains. However, there are a few patches of moderate risk in ND. Keep watching for extended periods of humid weather as the risk could change rapidly.

You may also notice a large portion of the southern US is now a gray color on the risk maps. This gray color indicates that the crop is mature or already harvested.

FHB Update from ND, 06/23/16

Most of the winter wheat is entering the dough stages of development. Spring wheat growth stages range from late tillering to milk development. Given the wide range of spring wheat growth stages, growers are encouraged to monitor the fields and the model in their respective area. Currently, the greatest scab risk for susceptible varieties is in the northeastern portion of the state. Additional pockets of scab risk for susceptible varieties are in northwest and southeast North Dakota. The weather forecast for the next few days is hot and dry with a slight chance of rain. These conditions will likely reduce scab risk in most areas of North Dakota.

FHB Update from SD, 06/23/16

Most of spring wheat has flowered but for late planted spring wheat, flowering may be still going on. Predicted risk for scab to develop is currently low throughout the state except in a few spots in Gregory and Lake Counties. Looking at rainfall forecast in the next few days, if a moderately resistant cultivar was planted, the risk for scab to develop seems to be very low.
