Gibberella ear rot on corn.
The 2018 corn growing season has been met with numerous disease challenges this season. From typical foliar disease issues like gray leaf spot and northern corn leaf blight, to new diseases like tar spot and bacterial leaf streak, the season has not been easy. As we have started to chop silage, ear rot and mycotoxin issues are also readily apparent.
In an effort to address the new disease, tar spot, we have put together a new video on what we know and don’t know. You can view that new video on YouTube, by CLICKING HERE. We have also assembled a second video on ear rots and mycotoxin issues in silage corn. That video can be found on YouTube by CLICKING HERE.
We hope you find these videos informative and help you gain ideas to manage these issues in your operation.
