Apply copper at T2 to mitigate ergot but it won't stop it altogether. Milling or feed wheat? That needs colour sorting but there are more choices about these days. Camgrain is the obvious local choice. Rands?
Copper at earlier timings I find better. Yes, colour sorter is the toy.
Did it come in the seed. Was told yesterday that some seed suppliers use a colour sorter and others do not.
