Preliminary Studies on Weed and Pest Management under Conservation Tillage
A field study was conducted to determine the effects of herbicide on weed management and to investigate the occurrence of weed, corn disease and insect under conservation tillage in the two-cropping area of the Shandong plain. Weed severity under conservation tillage and conventional tillage was greater without application of herbicide, however, weed in the summer field can be management by application herbicide in corn seedling stage. Corn disease and insect severity was similar in different tillage practices, corn virus disease and corn borer in field more serious. The finding of this experiment indicated that occurrence of corn disease and insect has closed relation with the amount of weed in field.
