Reduction in the seed reserve of subterranean clover following the application of 2,4-D amine, dicamba, dicamba plus MCPA amine or glyphosate in spring



Reduction in the seed reserve of subterranean clover following the application of 2,4-D amine, dicamba, dicamba plus MCPA amine or glyphosate in spring



Australian Journal of Experimental Agriculture 32(6): 701-706



The reduction in the net seed set by subterranean clover (mostly cv. Mount Barker), and hence the size of the seed reserve, was assessed at sites near Hamilton, Victoria (Australia), following the application of dicamba, 3,4-D amine, a mixture of dicamba and 2,4-D amine, or glyphosate, applied at early, mid or late flowering. Similar measurements were made on pastures dominated by cv. Yarloop near Seymour, Victoria, where either 2,4-D amine or a mixture of dicamba plub NCPA amine was applied at mid flowering. The experiments were conducted in 1984 and 1985 in both districts. At Hamilton, the clover seed reserve was 147 kg/ha before the treatments were applied. By early summer, the average seed reserve was 511 kg/ha where no herbicide was used and 211, 343 and 318 kg/ha where dicamba, 2,4-D amine or glyphosate were applied. The average reduction in net seed set for these 3 treatments was 80, 46 and 39%, respectively. Applying 2,4-D amine in addition to dicamba did not cause a further significant reduction in the seed reserve. The earlier in the flowering stage the herbicide was applied, the greater the reduction in net seed set, and so the smaller the final seed reserve. At Seymour, the Yarloop clover seed reserve was 246 kg/ha before the treatments were applied. The average Yarloop seed reserve by early summer was 754 kg/ha where no herbicide was used, 335 kg/ha where dicamba plus MCPA amine was applied. The average reduction in the net seed set for the 2 herbicides was 83 and 77%. This work indicates that no seed will be added to the seed reserve of Mount Barker or Yarloop subterranean clover if dicamba is applied at 1.0 L/ha before the clover reaches the mid flowering stage. As cultivars differ in their susceptibility to herbicides, extending these results to other cultivars needs to be done with caution.
