Conteúdo: | Dalapon at 2.8-11.2 kg/ha was applied in conjunction with ripping and oversowing of additional white clover to rejuvenate rain-grown clover pastures invaded by mat grass (Axonopus affinis) at Cooroy in SE Queensland. Herbicide treatment applied between June and July 1971 markedly increased clover yields in May and July 1972 and decreased mat grass yield in May 1972. By Nov. 1972 the herbicide's effect had worn off. Clover and mat grass yields were insensitive to herbicide application rates. Although 2,2-DPA,, may be useful in removint mat grass, its sucess as a pasture renovation tool appers highly dependent on timing, the degree of protection afforded by the grass to clover, ans moisture. The reduction in yield in the year of spraying and possible increase in weed production in disavantages to be considered implementing this practice on a commercial scale
