Abstract

Swinecress is a winter annual weed which infests Italian ryegrass sward in the Kyushu District. When cows eat the grass contaminated with this weed, they often produce the feed flavor milk having strong odor of the weed. Field experiments were conducted to control swinecress in Ital ian ryegrass sward by dense sowing from October, 1995 to May, 1996. Dense sowing of the ryegrass at 500g/a sowing rate controlled swinecress adequately. Post-emergence application of thifensulfuron-methyl controlled the weed, but it decreased the ryegrass yields both of first and second crops. When swinecress was grown at the sowing rate of 50, 100, 150 and 200g/a by mix-culture with the ryegrass sown at 250 and 500g/a rate, dry weight of swinecress in the ryegrass at harvest time was influenced more by the ryegrass sowing rate than by the swinecress sowing rate. It was suggested that dense sowing of the ryegrass was effective cultural method for the control of swinecress even in a field seriously infested by this weed. In a sensory test, panel members did not recognize the swinecress odor in the milk collected from the cow fed with the swinecress twice as much as that contained in dense sowing plot. In our experiments, it was concluded that dense sowing of Italian ryegrass is an effective cultural method for the control of swinecress in ryegrass sward.
