Abstract (en)
[origin: WO8901288A1] Commercially produced chitosan applied to cereal crop seeds at rates of 60 mu g to 1000 mu g per gram of seed enhances root development, crown diameter, mature straw strength and crop yield. Dry chitosan, when dissolved in dilute acid and neutralized, is applied directly to cereal crop seed with only minor modification to seed treating machinery and methods. In addition to a clear benefit in cereal crop yield, the chitosan treated seed can be planted early to reduce erosion and it can be planted in regions having soil infested with root rotting organims and not suffer extensive lodging that would prevent seed recovery by commercial harvesters.
