Soil moisture is necessary for herbicidal activity. Best results are obtained under cool, moist conditions. Warm soils accelerate degradation and may result in reduced efficacy. Application may be made under any weather conditions compatible with safe spraying. DO NOT APPLY to frozen soils on slopes or in any situation where runoff might occur before soil penetration.

Consult processors before treating crops intended for processing.

The soil should be mould-board ploughed to a depth of at least 15 cm before planting or sowing to a following crop. Do not sow any cereal or grass crop for 40 weeks following an application of Barclay Propyz.
