Effects Of Cold Temperatures On Disease

Feb 04, 2014

We have experienced exceptionally cold temperatures in Delaware this Winter. The main issue most growers are concerned with at this point is the impact on wheat or barley stands, particularly in late planted fields. What about the impacts of these temperatures on field crop diseases?

It is difficult to say for certain what impact these temperatures will have on field crop diseases. However, I speculate that it likely will negatively impact several pathogens that we saw during the rainy 2013 growing season, especially those that prefer warmer temperatures. In particular, the deep cold throughout the region will likely push the rusts further south, which may impact when initial infections occur on our crops. Frogeye leaf spot, which prefers warmer temperatures may also be negatively impacted. The cold temperatures may also impact overwintering potential of late blight in potatoes that may originate from cull piles or weeds. This does not mean that we will not have issues with these diseases in 2014, but the primary inoculum for some pathogens may be negatively affected.

Border View Farms is a mid-sized family farm that sits on the Ohio-Michigan border. My name is Nathan. I make and edit all of the videos posted here. I farm with my dad, Mark and uncle, Phil. We also have a part-time employee, Brock. My dad started the farm in 1980. Since then we have grown the operation from just a couple hundred acres to over 3,000. Watch my 500th video for a history of our farm I filmed with my dad.

I started making these videos in the fall of 2019 as a way to help show what I do on a daily basis as a farmer. Agriculture is different from any other industry and I believe the more people that are showing their small piece of agriculture, helps to build our story. We face unique challenges and stressful situations but have some of the most rewarding payoffs in the end. I get to spend everyday doing what I love, raising my kids on the farm, and trying to push our farm to be better every year. I hope that I can address questions or concerns that you might have about farms and agriculture.
