Abstract/Contents: | New varieties of Perennial ryegrass (Lolium perenne L.) have been bred from plants selected for their high level of dalapon tolerance. Experiments are reported in which it is demonstrated that these new varieties are more tolerant to dalapon than normal varieties under both glasshouse and field conditions. It is concluded that dalapon probably has a more strongly selective effect against unwanted grasses and a less adverse short term effect on productivity in swards containing the new varieties than in swards containing normal varieties. Certain aspects of the use of dalapon, such as dosage and time of application, need to be reinvestigated using tolerant varieties. |
