Information
Managing runoff of herbicides under rainfall and furrrow irrigation with wheel traffic and banded spraying
Level 1 General description
Purpose:
To investigate the effectiveness of banded spraying and controlled traffic management practices for managing pesticide runoff.
Methods (brief)
The transport of herbicides in runoff and sediment was measured during simulated rainfall and furrow irrigation on a hill furrow system.
Key findings (brief)
Band spraying on the hills was particularly effective for furrow irrigation because of the physical separation of the sprayed band and the water flowing in the furrow. Banding was most effective after herbicide application. The study also confirmed the tendency for residual herbicide to be persistent. However, when transported in the water phase of sediment water, partitioning increases with time after application.
Location
This study was conducted on a grain and cotton farm located between Oakey and Jondaryan on the Darling Downs, Queensland. Longitude and Latitude: -27o25'50'' 151o37'40''
