Weed Control In Cereals And Pastures Including Declared Plants., J. Peirce, B. J. Rayner

Experimental Summaries - Plant Research

Trial 90C49

Grass and broad leaved weed control in direct sown crops.

Location: Chapman Valley Research Station.

The low rate of sprayseed with diuron was not as effective on the grasses. It may indicate some antagonism within the mix as the same rate of sprayseed with metribuzin did not cause any drop in grass control. The addition of 2, 4-D amine may have boosted the mixes activity on capeweed as the sprayseed metribuzin mix was not very good on capeweed.
