Evaluation location: Washington, United States
Safflower grown in a drip-irrigated field at our Central Ferry farm which is in eastern Washington, United States along the Snake river, elevation about 200 meters. Seeds were treated prior to planting with Thiram 50 wp fungicide at the rate of 4oz/100 lbs of seed. Plots were direct seeded in double rows, 6 meters long on April, 2008 at the Central Ferry, Washington, Research Farm. The plots were caged with fiberglass screen a few days before flowering. Rust notes were taken when cages were removed after flowering was completed in the entire plot and most plants had begun to dry.
