| Abstract/Contents: | "Corn gluten hydrolysate has been identified as a natural preemergent herbicide in greenhouse studies. The objectives of this study were to identify rates of hydrolysate that reduce seed germination in the greenhouse, and then to determine hydrolysate rates for crabgrass (Digitaria spp.) control in turf in the field. An additional objective was to test humic acid and soybean oil for their capacity to enhance the herbicidal activity of the hydrolysate. Hydrolysate was applied at 0 to 400 gĀ·mā»Ā², humic acid from 0 Ī¼lĀ·mā»Ā² to 5 mlĀ·mā»Ā², and soybean oil from 0 to 230 Ī¼lĀ·mā»Ā² in greenhouse studies with perennial ryegrass (Lolium perenne L.). Hydrolysate rates of 0, 100, 200, and 400 gĀ·mā»Ā² reduced seedling survival 15, 15, 35 and 70%, respectively. In field studies conducted in a mature stand of Kentucky bluegrass (Poa pratensis L.), hydrolysate was applied at 0 to 200 gĀ·mā»Ā², humic acid from 0 Ī¼lĀ·mā»Ā² to 4.1 mlĀ·mā»Ā², and soybean oil from 0 to 230 Ī¼lĀ·mā»Ā². Hydrolysate at 200 gĀ·mā»Ā² reduced crabgrass 69% and produced the best visual quality as compared with the control. Neither humic acid nor soybean oil affected the performance of the hydrolysate in the greenhouse and field studies." |
