Weed Research. 8. Weed Control In The Vineyard, Geoffrey A. Pearce, W. R. Jamieson

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

WEED control in the vineyard has been achieved by cultivation for many centuries and it is only during recent years that attention has been given to the use of herbicides for this purpose.

Today there is little risk to the vine in using any one of the herbicides listed in this article, and in general the main considerations governing the use of chemicals for weed control are the cost of the operation and the effect which it is desired to achieve.

Weeds Of Western Australia : Cape Tulip (Homeria Breyniana (L.) Lewis And H. Miniata Sweet), G R W Meadly

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

SOUTH Africa has provided us with a number of undesirable weeds including doublegee, Berkheya thistle, Guildford grass and stinking roger, but outstanding among the weed introductions from that country are two species of Homeria known as Cape Tulip.

The salmon-coloured flowers and long grass-like leaves are known to farmers in many localities extending from Geraldton to Albany and as far east as Bruce Rock and Merredin. Beyond the metropolitan area the largest infestations occur in the Northam, York, Beverley and Williams districts where thousands of acres of good land are affected.

Weed Research. 7. Weed Control Around The Yard, Geoffrey A. Pearce

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

MANY farmers and city householders have weed problems around houses and sheds which can be readily overcome by treatment with appropriate herbicides.

The risk from fire through weeds and unslightly growth can easily be removed and an area free of any plant growth can be maintained with little effort for a considerable period.

Soursob (Oxalis Pes-Caprae L.), G R W Meadly

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

DURING winter and spring, the yellow colouration of paddocks is not always due to the flowers of the widely distributed Capeweed.

In some districts, particularly in the Avon Valley, the yellow-flowered soursob (Oxalis pes-caprae L.), has become firmly established.

The genus Oxalis contains 800 or more different species, the two main natural centres of distribution being South Africa and tropical and extra-tropical South America.

Weed Control In Cereals, G R W Meadly

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

WITH seeding almost completed, it is appropriate to review our knowledge of weed control methods in order to undertake any necessary planning.

Although cultural operations provide the first line of attack in the control of weeds in cereals, chemicals are playing a very important and increasing part.

The principles underlying cultural methods, including prevention from seeding and exhausting dormant seed reserves in the soil, are well known and it is intended to devote this article largely to the use of chemicals as herbicides, along with the various implications.
