Prosun is a seed coating for sunflowers that provides added weight and a smooth, slick finish that enables sunflower seeds to flow smoothly through planters. Designed for precision air planters, Prosun seed coating helps growers achieve accurate field populations. Prosun pellets may be applied to raw or treated seeds. Seed distributors may provide crop protection chemicals for application as a filmcoat during the coating process.

Germination and emergence trial result
No significant differences in germination or emergence were observed. Data represents four trials combined: NDSU REC’s Carrington & Minot 2017, 2018.
