South Australian Grains Industry Trust funded research conducted by Trengove Consulting in 2017 found ryegrass weed seed kill was 93% at 2250 rpm and increased to 98% or greater at normal operating speeds (2500–3000 rpm). Results also showed than 99% control of several other species including wild radish, brome grass,wild oat, bifora, bedstraw and tares and increasing chaff flow rate (harvest rate) did not reduce control of these species

The South Australian Grains Industry Trust is using one of the three test stands to trial the Seed Terminator against a range of crops including Wheat, Canola, Lentils, Beans, Chaff laced with Ryegrass, Broom Grass, Turnip, Prickly Lettuce, Medic, Tares, Wild Radish, Bifora, Bedstraw, Marshmallow and Wild Oats. Early results show Seed Terminator is over performing.
