Factors affecting the persistence of some residual herbicides in maize silage fields

Assesses the level of residual activity of common maize herbicides, including atrazine and acetochlor applied pre-emergence and mesothrione and nicosulfuron applied 6-12 weeks after planting, in commercial maize (Zea mays) silage fields on typical soil types in different regions (Waikato, Taranaki and Canterbury). Investigates the influence of soil characteristics and rainfall amount and timing on the disappearance of residues in different soils.
