Abstract

Trial 90WH74

Crop establishment trial

Location: Wongan Hills Research Station.

To assess the effect of timing of roundup and sprayseed application and cultivation on crop growth.

Trial 90AB19

Ryegrass control in wheat using slow release trifluralin.

Location: Katanning.

To compare 2 experimental formulations of controlled release trifluralin at 4 rates and 2 timings with some commonly used herbicides for the control of ryegrass in wheat.

Trial 90ME84

Early application of 2, 4-D to wheat.

Location: Corrigin.

To assess the use of 2,4-D.amine at early times of application for the control of broadleaf weeds in wheat.

Trial 90WH92

Early application of 2, 4-D to wheat.

Location: Wongan Hills Research Station.

To assess the use of 2, 4-D.amine applied early to wheat at various rates of application.

Trial 90ME83

Grass and broadleaf weed control in wheat with hoegrass tankmixes.

Location: Corrigin.

To control grass and broadleaf weeds in wheat with hoegrass tankmixes.

Trial 90NO130

Grass and broadleaf weed control in wheat with hoegrass tankmixes.

Location: York

To control grass and broadleaf weeds in wheat with hoegrass tankmixes.

Trial 90NO132

Wild oat control in wheat - rates of grasp x timing of application.

Location: York

To assess the use of grasp at 4 rates and 2 timings to control wild oats and ryegrass in wheat.

Trial 90NO129

Wild oat control in wheat - timing and rates of application of grass controllers.

Location: York

To compare grasp, hoegrass and puma at 2 rates and 3 timings for controlling wild oats and ryegrass in wheat.

Trial 90ME82

Grass control in pasture - rates of kerb.

Location: Corrigin.

Grass control improved with increasing rates of kerb up to 1.0kg/ha. Inexplicably the 1.5kg/ha rate was inferior to the 1.0kg/ha rate. An error in mixing the kerb is the only logical explanation.

Trial 89NO73

Silvergrass control in pasture - recrop.

Location: Avondale

This trial was recropped to wheat in 1990. The site was direct drilled and no in-crop herbicides were used or needed. Silvergrass control in 1989 had no bearing on the level of weeds in the 1990 crop. However the level of silvergrass control achieved in 1989 was strongly reflected in the wheat yield achieved in 1990.

Trial 90LG79

Grass control in pasture demonstration.

Location: Varley.

Site: Clover based pasture with silvergrass, barley grass, ryegrass, bromegrass, doublegee and capweed.

Trial 90NO131

Silvergrass control in pasture - simazine rates x timing of application.

Location: West Dale.

To control silvergrass in a sub-clover.

Trial 90WH93

Doublegee control in pasture.

Location: Wongan Hills Research Station.

To control doublegee in a sub-clover pasture.

Trial 90A11

Chemical control of summer weeds - Chenopodium (spp) goosefoot.

Location: Avondale Research Station

To control goosefoot (Chenopodium spp) in a pasture paddock following summer rains.
