Abstract
US Patent No. 5,030,268 discloses that corn gluten meal, the protein f raction of corn (Zea mays L.) grain, can be used as a natural pre-emer gence herbicide. However, corn gluten meal is insoluble in water, and this characteristic renders it difficult to apply as a herbicide. To s eek a water-soluble material with more potent herbicidal activity, the phytotoxicity of various samples derived from corn gluten meal and ot her related crop materials were evaluated by using three different gra ss species under controlled environments. Greenhouse and growth chambe r bioassays showed that the sample of enzymatically hydrolyzed corn gl uten meal was more herbicidally active than the corn gluten itself and was highly water soluble. Gluten hydrolysate prepared with bacterial source proteinase had the greatest inhibitory activity to the root gro wth of germinating seeds. This water-soluble material derived from cor n gluten meal had a growth-regulating effect on the root system and ca n be used as a natural herbicide.
