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.

Beating The Blackberry, J H. Moore, E. B. Hoskins

Journal of the Department of Agriculture, Western Australia, Series 4

The blackberry is an aggressive, strongly-growing plant that has spread throughout parts of the south-west of Western Australia.

Although most blackberry infestations on agricultural land have been dramatically reduced since compulsory control measures were introduced 30 years ago, about 3,600 hectares are still infested today.

Recent research has shown that three new herbicides are highly effective against blackberry, and much safer to use than the older ones.

Effective biological control of blackberry may also be possible.

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,

Skeleton Weed : How Serious A Threat In Western Australia?, F D. Panetta, J. Dodd

Journal of the Department of Agriculture, Western Australia, Series 4

Skeleton weed is probably the most serious weed ever to threaten the Australian wheat industry. It interferes with wheat cropping at two stages: through competition with the growing crop, particularly for nitrogen and water during the crop's development: and later through the production of a tall, wiry flowering stem which tangles in harvesting machinery and can make harvesting difficult, if not impossible.

The weed is a major problem in eastern Australia although a combination of cultural, chemical and biological control programmes is helping to reduce its impact.

In Western Australia, skeleton weed is being contained mainly by eradication efforts. Weed …

Cereal Crop Tolerance To Herbicides, D Bowran, R Madin, A Lindsay

The 1984 experimental programme was a continuation of that started in 1981. The programme was aimed at evaluating the major herbicides in current use for cereals as well as new herbicides against the recommended varieties at three main sites, these being Wongan Hills, Merredin and Mt Barker. In addition Stage 4 breeding lines were evaluated against the same herbicides but only at Wongan Hills. The herbicides used and their rates and time of application are presented in Table 1. Herbicides were applied at both the recommended and twice the recommended rates of application, except in the breeding line trial where …
