Plant Withholding
To minimise soil residues, treated area should be deeply cross cultivated to ensure maximum dispersal of residues. Ryegrass and small grains should not be sown in areas treated with Guardian within the previous 5 months. |

Post-emergence herbicide used in maize grain and maize silage crops for the control of perennial and annual grass weeds
Has activity on a number of broadleaf weeds
Compatible with most other commonly used post-emergence herbicides, use with Benefit for best results
Guardian provides superior control of many hard to kill annual and perennial grass species in maize as well as some broadleaf weeds such as triazine and dicamba resistant Fathen. Can be readily mixed with many other post emergence herbicides commonly used in maize crops such as Ravensdown Atratec and Dicam 480.
Benefit adjuvant is required in many situations to be added when using Guardian. Benefit should be applied at 500ml per 100litres of water. Refer to Guardian label.
Application
Apply Guardian evenly to the weed canopy using ground based spray equipment at a minimum water rate of 200L/ha. Position the boom nozzles between the rows of maize for direct coverage of weeds. The use of nozzles on droppers from the boom will improve target weed coverage. For best results Guardian should be applied before weeds have reached the 4 true leaf stage. Weeds past the 4 true leaf stage may only be suppressed. The maize crop growth stage best for application is between 2 and 8 leaf stage when the crop is growing vigorously without moisture stress. Do not apply Guardian into the maize as crop damage may occur.
Mode of action
Guardian is rapidly absorbed by foliage and translocated throughout weeds. This stops the synthesis of vital plant growth chemicals. Weeds stop growing immediately and discolouration of leaves occurs, followed by dieback that spreads slowly throughout the weed.
