Night spraying: pesticide efficacy with nighttime application
Timeline: April 2012 – December 2015
- Alberta Barley
- Alberta Canola Producers Commission
- Agriculture Opportunity Fund
- Alberta Agriculture and Rural Development
- Agriculture and Agri-Food Canada
Alberta Barley funding: $6,000
Total funding from other partners: $174,000
The project aims to determine if applying herbicides at night is a practical option for farmers; to generate unbiased data on the efficacy of and tolerance of night application of herbicides; and to uncover possible issues or complications associated with night spraying. So far, the best herbicide results have come from daytime spraying for pre-seed burn down and the best fungicide results on barley have come from early-morning spraying. The project could expand to include insecticide applications.
Benefits for farmers:
Night spraying may provide a feasible alternative to poor daytime conditions and could potentially improve efficacy due to greater absorption. Night spraying may provide farmers with the option to cover the same acres in a shorter period or to cover more acres with the same equipment.
