Double breaks – a double shot at annual ryegrass

Short black, long black, double shot, double break? Coffee preference is a little like crop sequences.

Perhaps you’re a ‘short black’ wheat-canola type, strong on inputs?

Or a ‘long black’ type who likes to dilute their rotations a bit more?

Or are you a ‘double shot’, throwing in a few break crops in a row for maximum effect?

When it comes to managing annual ryegrass populations, Tony Swan and the research team from CSIRO Plant Industry and FarmLink, have shown that ‘double shots’ are the key. Growing two break crops in sequence (broadleaf crop, hay crop or long fallow) was more effective in reducing resistant ryegrass numbers to manageable levels than a single break crop or continuous wheat over a three-year rotation.

And it can still be profitable.
