FHB Update from US, 04/10/19

The focus of the Fusarium Head Blight Prediction Center moves North this week. Wheat in AR, TN and NC should be approaching the critical stages of growth over the next 7 to 14 days. There may also be some areas of northern LA, MS and AL that are still at vulnerable growth stages. At this point, the risk of severe disease is low, in most of these areas. There is a region of southern LA and MS that appears to be a moderate or high risk, however, wheat in this area is likely past the most vulnerable growth stages.

FHB Update from GA, 04/02/19

Currently, FHB risk assessment map indicates low development potential across Georgia. However, weather patterns and forecasted rain events for the weekend and following week can potentially increase the risk of FHB. Therefore, remain vigilant.

FHB Update from VA, 04/01/19

Welcome to the 2019 FHB commentary for Virginia! As the wheat crop in the state begins to approach flowering, comments regarding risk of Fusarium infection and management recommendations will be posted.

FHB Update from US, 04/01/19

The Fusarium head blight prediction center resumed activity for the 2019 growing season this week. The southern states including LA, MS, AL and GA are the current focus of the prediction effort. Over the next few weeks, wheat in these states will likely reach the flowering and early stages of grain development that are most vulnerable to infection by the Fusarium fungus. The current risk of severe disease is low in the southern region of the US.

FHB Update from US, 09/12/18

Thanks for your interest in the Fusarium head blight prediction center. The wheat growing season has ended in most areas of the US and the Fusarium head blight prediction center will no longer be generating new risk maps. The maps for the 2018 growing season will be available for your review during the next few months. The system is scheduled to resume activity in February-March of 2019. We hope to see you then.

FHB Update from US, 07/31/18

Much of the US wheat crop should be beyond the growth stages that are most vulnerable to Fusarium head blight. The moderate gray color of the map suggests that the crop is already mature and being harvested in much of the country. Growers in the far northern regions of ND and MN may have some late maturing fields to monitor. Therefore, the risk tool will continue to run until approximately Aug 15th.

FHB Update from ND, 07/20/18

Spring wheat is entering late stages of dough development in several areas of the state, however there are some late-planted fields that have started to flower. The greatest amount of scab risk for susceptible and moderately susceptible varieties is in the eastern third of North Dakota. Continue to monitor the growth stage in late planted spring wheat and durum and make a fungicide application at early-flowering.

FHB Update from SD, 07/16/18

Most of the spring wheat is past flowering but for late planted or late maturing spring wheat varieties, flowering may still be going on. These fields are at risk for Fusarium head blight (FHB or scab). The FHB prediction tool is showing moderate to high risk for FHB mainly for the eastern-most counties and a few southeast areas. Spring wheat in these areas that is at flowering should be protected from FHB using a triazole (FRAC group 3) fungicide. For fields that were not treated due to wet conditions, a fungicide can still be applied within 6 days post flowering, however, the most efficacious timing for FHB management is when 50% of the wheat plants are at flowering.

FHB Update from ND, 07/05/18

Spring wheat and durum growth stages vary across the state. Some fields are entering early dough development, while later planted fields are in the boot stage. For susceptible varieties that are entering flowering stages, several pockets of moderate to high risk exist in the state. Risk will likely increase on the eastern half of North Dakota in the next few days. Continue to monitor the growth stage of fields that are entering the flowering stages of development and apply an effective triazole (FRAC 3) fungicide when needed.

FHB Update from SD, 07/05/18

The risk for Fusarium head blight (FHB, scab) remains high for the most of the eastern half of the state and some parts of north and southwest SD. Spring wheat that is at flowering or just done flowering may benefit from a triazole fungicide application. Although the most effective timing is at flowering (50% of the plants flowering), rainy weather conditions may prevent fungicide spraying at this growth stage. Research shows that there is still protection from FHB and DON within 6 days after flowering, therefore a fungicide can still be applied within this window.
