Pursuit For Weed Control In Peas., S. Curtin
Experimental Summaries - Plant Research
All trials were located in Merredin.
Trial 90ME86
This trial was one of the best demonstrations of pursuits effectiveness against mustard in particular. Other weeds were rough poppy and ryegrass and a small amount of cereal and doublegee.
250 ml applied immediate before seeding (IBS) was by far the best treatment with 100% control of mustard and poppy and good ryegrass control. This is in contract to 375 ml most emergent which had good control of mustard (77%) and suppression of ryegrass. There was no yield advantage from the post emergent treatment but there was a 55% yield increase from …

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.

New Block Badgingarra Rs Late Time Of Seeding., J. W. Bowden, R. J. Lunt
Experimental Summaries - Plant Research
Trial 89BA33,
Location: Badgingarra
Based on a 1.5 t/ha potential yield, the strategic treatment was planned to be 120 kg urea/ha 4WAS. However, the crop was poorly established and so NH4NO3 was used in the hope of getting better tillering than would be possible with the slower release urea source. Gambling on equal dollars to urea for 2/3 N, but believe that twice as effective.
DAP was used to place nitrogen with the seed in case there was no rain of significance after seeding. This nitrogen (only 5 kg/ha) was probably lost with the rains of 20-28/7/89 (50 mm). Urea …
