Dont won't to take the risk of crop failure, when we have over options. Would happily grow it on a area based contract rather than a yield based one next year!
The worst bird attacks i have seen, has been about 10% in worst hit fields, but less that 2% on our whole acreage.
I am on a yield based contract, as i don't get paid until i convert it to milk
Mesurol add about 15% to the seed price, which is already high. It cost about 1,6% of an average crops value here, so you would have to loose at least that, just to break even. For me it's not worth it. I drill for a few other farmers, and they all use mesurol. They don't really know why, other than "we use to"
