Annual Ryegrass Toxicity Research Summary Of Experiment Results., V. Nieman, A. G. P. Brown, R. Madin

Experimental Summaries - Plant Research

Experiments were set up to screen a range of herbicides which might give improved control of Anguina agrostis over the currently recommended paraquat. Two experiments examined Roundup, Fusilade and Sertin at two rates and two experiments screened eight herbicides at five rates from two x "label recommendation" to 0. 99 x Standard treatment was paraquat at 550 ml. Plots were 3 m x 30 m in the first two experiments and 3 x 5 m (per dilution) in the second. The herbicides were applied on 4/9, 17/9, 24/9, 1/10 and 9/10 (Zadoks stages 32 - 58). There were three replications …

The Tolerance Of Cereals To Herbicides., D. G. Bowran

Experimental Summaries - Plant Research

Herbicides affect not only the weeds present in a crop, but also the crop itself. In the absence of weeds, both positive and negative responses to herbicides have been reported in the literature. The negative responses are the most important, especially if yield is decreased below the economic threshold for herbicide use. Factors which are important in determining the level of crop response to a herbicide include the crop species and variety, the timing of the herbicide, the rate of herbicide and the environmental conditions under which the crop is growing.

Influence Of Soil Acidity On Barley Production., P. J. Dolling, A. R. Little

Experimental Summaries - Plant Research

A soil survey of 38 sites in barley growing areas of Western Australia was carried out in 1984. It was found that 53% of topsoils surveyed had a pH less than 5.5, acid enough to suspect barley yields might be affected. In 1985 an extensive field trial proqramme was established at 9 sites. The sites were selected from the 1984 survey and they varied in their level of acidity from mild to severe. 85NA, 85NA2, 85NA5, 85NA4, 85NA3, 85KA3, 85KA4, 85KA5, 85KA6, 83N046,
