Disease

[agstar77]

With the large amount of precipitation in Sask, will Fusarium show up this year and how will quality be affected? Grading standards on Fusarium are set to change Aug 1st.

This is something farmers should be paying attention to.

Murray Hartman/Oilseed specialist with Alta. Ag. did a good call of the land on Clubroot in canola. Note the need (in Alberta at least to clean muddy equipment between fields) to minimize the probability of spreading the disease.

Forget about tolerances the cwb takes care of that through special fusarium programs, but we have had that discussion before.

Your question is valid and there will be a good chance of high infestations of fusarium across the prairies. But being able to blend it will be more of a challenge due to lower acres of wheat and the horrible weather we are having, which slows or eliminates preventative action.

It is also an a year when farmers in areas which have not had fusarium head blight in the past will have to watch. Realize the time for spread of the disease is a least a month away but if the wet conditions continue and the summer is hot/humid, farmers will have to watch for symptoms in their crop scouting. Fusarium is a disease that expands based on climatic conditions and adaptation to new areas. Once established, it will be a part of cropping for a long time if not forever.

And lucky for us, the cwb promoted growing wheat in areas that were infested with fusarium.

Great program and probably gained alot of support from those farmers.

The cwb doesn't work in our best interests. How do they combat the problem for this year when its a wide spread problem? Tell everyone that its getting sold as feed, when guys that have been blending the shit off from manitoba have received no compensation for doing just that.

Fusarium was non existant here 2 years ago,but then all hell broke loose.Maybe from all the glyphosate we spray now? Just a heads up,if you don't have it now,it WILL get you sooner or later.

Just curious where you are located.

Fusarium outbreak requires 3 things. Presence of the disease in the soil (fusarium graminearium), right climatic conditions (rainy, hot, humid) and a host crop. The disease can get established in a number including through the air, on seed, soil transfer between fields, etc. What happens is that fields can have a low presence of the disease which builds up gradually over time but all of a sudden the right climatic conditions come together and the disease takes off as a full blown outbreak. The disease also has the ability to adapt. This is a concern in Alberta/black soil zones that are cooler than Manitoba but otherwise similar to Manitoba/Eastern Saskatchewan.

I have heard about the link between glyphos and fusarium - could it be because the soil is wetter than conventional tillage and cooler soil temp breeding the fusarium?

Haven't heard the releationship myself but not an expert on fusarium. Know it can be carried on crop aftermath (straw and corn stalks).
