EVALUATION OF CORN GLUTEN MEAL AS A NATURAL, WEED CONTROL PRODUCT IN STRAWBERRY
Corn gluten meal (CGM) has been patented as a natural weed control product. It also provides approximately 10% nitrogen by weight. Greenhouse and field trials were conducted in 1991 and 1992, respectively, to evaluate the effects of CGM as a natural, weed control product and its effects on the growth and development of strawberry plants. Results from the greenhouse experiment indicated leaf area, leaf number and leaf dry weight were greater on CGM treated ‘Honeoye’ daughter strawberry plants than on untreated (control) plants, possibly due to an increase in available nitrogen. Application of CGM at rates up to 13.02 g/dm2 on the soil media surface did not affect the growth and development of the mother or daughter strawberry plants. Results from field experiments indicated weed control was possible with applications of CGM. Incorporated CGM reduced percent weed cover in strawberry plots from 80% weed cover in the untreated control to 52% for 98 g/m2, 27% for 196 g/m2, 17% for 294 g/m2, 13% for 392 g/m2, and 8% for 490 g/m2.
