How Long Maize Guard is a soil applied, pre-emergence herbicide, and is taken up by the shoots and roots of germinating weeds, where it interferes with protein formation and plant growth. Susceptible grass species often fail to emerge.

Plant Withholding There's no withholding period for Maize Guard, however if crop failure occurs consult with your Ravensdown Agrochemical Territory Manager for advice on suitable crops to plant and procedures to limit residual carryover. |

| Barriers to effectiveness |
Barriers Rainfall
No rainfree period is required, because Maize Guard is a soil applied pre-emergence herbicide. However if soil conditions are very dry, then 10mm of rainfall or irrigation is required within 7 days. Under dry conditions, soil incorporation will assist activity. Conversely if soil conditions are very wet and cold for a prolonged period there may be risk of some crop damage. |

For pre-emergence weed control in maize and sweetcorn crops
An essential part of any maize planting programme
Use in combination with Atratec to increase the weed spectrum
Early removal of emerging weeds is critical to achieving high maize yields. Maize Guard has robust activity across a range of soil types including peat, sands and clays and is also more active than other compounds in dry conditions. Organic soils and low soil moisture do reduce activity.
Application
Apply immediately after planting for best results, late application can result in lower levels of weed control. Use 3 litres of Maize Guard per hectare in 200 - 300 litres of water, ensuring even coverage of soil surface. Tank mix with Atratec herbicide and / or Halexcs or Toppel insecticide. Surface applied applications of Maize Guard will work under dry soil conditions, but soil moisture will improve activity. A fine firm seedbed will improve weed control. Maize Guard can be applied and incorporated pre-planting. This can be done by performing normal seedbed preparation to achieve a seedbed free of plant residues and clods. Then surface apply Maize Guard and follow with a tined cultivator, incorporating to a maximum depth of 5cm. Maize can then be planted.
Always refer to the label for application rate details
Applied following planting and before crop and weed emergence. It is absorbed mainly through the shoots of the germinating grass weeds and the roots of germinating broadleaf weeds, where it interferes with protein formation and plant growth.

Shelf life
When stored appropriately this product should show no significant degradation for two years from the date of manufacture. Please contact your Ravensdown Account Manager, or the Customer Centre on 0800 100 123, for further information about the use of any product that is older than this.
Ravensdown Atratec may be added to the tank mix to improve the spectrum of activity. Alternatively Atratec or Dicam 480 may be applied as a follow-up post emergence treatment where high populations of fathen and willow weed exist.
