What is it about?
The glyphosate-resistant Italian ryegrass was found on paddy levees in central Japan, thereby making control of the grass by using glyphosate less effective. In this study, physical control methods were tested in order to more effectively control glyphosate-resistant Italian ryegrass on rice paddy levees.

Why is it important?
Physical control methods were tested that combined the timing and frequency of mowing in order to more effectively control glyphosate-resistant Italian ryegrass on rice paddy levees. A 3 year field experiment was conducted from 2012 to 2014 in a western region of Shizuoka Prefecture, where glyphosate-resistant Italian ryegrass has become dominant.Five treatments were tested: (i) mowing once before the flowering of the grass (i.e. conventional mowing measure); (ii) mowing once during flowering; (iii) mowing twice during flowering; (iv) glyphosate application before flowering (i.e. one of the conventional mowing measures); and (v) no treatment.
Perspectives
Improved the control of grass require when resistance of herbicide has been appear. The control of the grass necessary to maintain ecological balance. The best control could be the effective component of an integrated weed management system. This article provide the effective control of glyphosate-resistant Italian ryegrass.
