FHB Update from AL, 04/11/18

Scab risk for Baldwin and Mobile Counties is high as compared with the low risk for scab development across the remainder of Alabama. Wheat is flowering across Southwest Alabama, so producers should make a fungicide application before the next rain event scheduled for this coming weekend. A low level of rust activity along with a low to moderate level of Septoria glume blotch was also noted in Baldwin Co. With the exception of trace levels of powdery mildew and Septoria leaf spot, disease activity at two North Alabama locations was low on wheat showing the flag leaf but no seed heads.

FHB Update from GA, 03/30/18

FHB risk assessment map indicates low development potential across Georgia at this time. Recent weather patterns and forecasted rain events for the following week can potentially increase the risk of FHB.

FHB Update from AL, 03/25/18

Currently, the risk for scab development across Alabama is low. Generally, weather in the southern two thirds of AL has been dry and cool over the last week as wheat has begun to lower. Overall disease activity in wheat is low. To date, leaf rust has not been diagnosed in variety trials at two South AL locations. Also, very little disease activity in forage, grain, and malting barley variety trials in Central AL.

FHB Update from US, 03/21/18

The Fusarium head blight prediction center resumed activity for the 2018 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 LA, 03/21/18

Wheat stages across the state range from jointing to flowering. For the most part, risk for scab for flowering wheat is low this week. However, there is a chance of rain in the forecast for next week. Plans should be made to protect vulnerable wheat prior to rain events.

FHB Update from US, 09/05/17

The wheat growing season is over in most areas of the country and the Fusarium prediction center is no longer actively generating new risk maps. The risk maps from 2017 will remain available until the system resumes activity next February. To access these risk maps, select the assessment dates of interest from the calendar interface to the left of the risk maps. Thanks for a great season. We hope you will join us again in 2018.

FHB Update from US, 08/02/17

The focus of the Fusarium prediction center remains on the northern spring wheat production regions of ND, and MN. The risk models are indicating moderate to high risk for the northern areas of these states. Some late planted fields may still be at flowering stages that are most vulnerable for infection. Growers should in these areas should work with local extension specialists to evaluate the risk in their area.

FHB Update from ND, 07/20/17

Scab risk for susceptible varieties northeast ND is moderate to high. The northern half of the Red River Valley also is in a moderate to high risk for scab. Several fields are progressing into dough stage, yet there are several late planted wheat fields that are flowering. Pay attention to the growth stage in late planted fields and use the model to assess scab risk. With the recent rain and higher humidity projected, scab risk is likely to remain moderate to high in areas of elevated risk.
