Worse Than Expected, It Needs To Come Off ASAP! Do I Need To Change Varieties??

Darcy has come to have a look and see when we need to chop but it's a bit worse than he feared.
Do I need to change it up for next year? Is leaf blight going to happen year on year?

Hey I’m Andrew The Once A Day Farmer, I farm alongside my father on my family dairy farm in New Zealand.
Our Dairy system is quite unique as we only milk our 320 jersey cows Once A Day (hence the name), and they stay outside on grass for 365 days of the year!!
