The Value Of Break Crops In Weed Management, Wayne Parker, Ian Pritchard, Abul Hashem

Bulletins 4000 -

This publication discusses the effect on weed management of the inclusion of break crops (lupin, field pea, chickpea, faba bean, lentil and canola) in the cropping rotation compared to a rotation of continuous cereals.

Including break crops in the cropping rotation allows weed management options unavailable or not suited in wheat. For example, growing field peas allows crop-topping/ desiccation for weed seed set control, crop topping cannot be used in wheat without severe yield loss. Problem weeds can be targeted through break crops, for example, grass weeds are generally more easily controlled in break crops than in cereals. Most weed …

Diagnosing Crop And Pasture Problems With Detective Doug, Doug Sawkins

Bulletins 4000 -

There are numerous publications for diagnosing crop and pasture growth problems. Although they are excellent for experienced people, they can be time consuming and possibly misleading for the less experienced.

Many guidebooks assume that the user has already decided that their problem falls into the category covered by their particular guidebook, for example, a disease, pest or herbicide problem.

Guidebooks are often based on plant symptoms. However, in the field, symptoms vary and different problems can have similar symptoms.

This bulletin presents a problem diagnosis method that uses plant symptoms and paddock clues. It can be used to draw up …

Control Take-All And Gain Other Benefits Of Eliminating Grass From Ley Pastures By Chemical Manipulation, W J. Macleod, Gordon Macnish

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

Take-all is the most serious root disease of wheat and barley in Western Australia.

The fungus which causes take-all (Gaeumannomyces graminis var tritici) is wide spread throughout the wheatbelt but is most common in the high and medium rainfall regions (400mm to 750mm average annual rainfall, see map).

Elsewhere in the wheatbelt the presence of take-all affected cereal plants and the loss of crop yield may go unnoticed unless the roots of cereal plants are examined in detail.

Tolerance Of Cereal Crops To Herbicides, D G. Bowran

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

Herbicides have come to play an important role in the control of weeds in Western Australian cereal crops, with some estimates showing that sufficient herbicide was applied to treat every hectare of cereal grown in 1984.

While the use of herbicides reduces competition from weeds, they may have a hidden cost. As chemicals which affect plants, herbicides may also affect plants, herbicides may also affect and damage the crop which they are protecting. The crop may possibly fail, and some or all of the economic benefits obtained from the chemical control of weeds may not be realised.

The Control Of Annual Ryegrass, Geoffrey A. Pearce, J. E. Holmes

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

A valuable pasture plant - one of the worst weeds if cereal crops - host to a potent animal disease toxin.....annual ryegrass is the subject of intensive studies by the Department of Agriculture.

This article reviews current research into the control of annual ryegrass in crops.

The Economics Of Spray Seed, J W. Malcolm

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

THE "Spray Seed"* technique has many advantages over conventional cultivation methods of weed control. Some of these are matters of convenience, preference or opinion, and these cannot be measured in general economic terms.

However, most farmers are in the business to make money and as making money becomes harder they are more concerned with the extra money a new move is likely to earn for them.

How Profitable Are Herbicides For Weeds In Crops?, J W. Malcolm, G. A. Pearce

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

BEFORE spending money on chemical weed control in crops, a farmer needs to know how profitable the operation will be. He may also be influenced by other things such as the need for weed-free seed, but the most important consideration should be an increased cash return.

If a herbicide is used to control weeds in a crop, the extra yield achieved must be worth more than the cost of the herbicide and its application for the treatment to be profitable.

This article gives guidelines to help farmers estimate the likely profitability of herbicide treatments for quota and non-quota crops.

A Cheaper Herbicide For Wild Oats, Geoffrey A. Pearce

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

A NEW herbicide, *NEOBAN, will reduce the cost of chemical for the control of wild oats in wheat and barley to $2.50 per acre.

Because of the cost of herbicides for wild oats during the past two years, the acreage treated has been declining steadily.

Farmers who thought that spending about $4 per acre was worth while will be delighted with Neoban.

Chemical Cultivation : Its Place In Crop Planting, Geoffrey A. Pearce

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

PROGRESS in the field of chemical weed control has been spectacular in recent years. Despite the cut-back in expenditure on herbicides, the idea of replacing cultivation with chemical sprays is attracting great interest.

Progress In Research On Noxious Weeds, Geoffrey A. Pearce

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

RESEARCH on noxious weeds has enabled the development of many practical methods for the control of these weeds.

Where the recommended treatments have been accepted by farmers, large scale operations have reduced the areas infested and stopped spread into new paddocks.

Chemical Ploughing, Geoffrey A. Pearce

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

PROGRESS in the field of chemical weed control has been spectacular in recent years. One field that is attracting interest is the idea of replacing cultivation with chemical sprays.

Weed Control In Pastures : A Practical Approach For Sheep Areas, Geoffrey A. Pearce

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

IN the past, chemical treatments for the control of weeds in pastures have been costly and severe on pasture, and have had to be repeated over a number of years. The method outlined in this article overcomes nearly all these disadvantages.

The Control Of Weeds In Cereals, Geoffrey A. Pearce

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

PRACTICALLY all broadleaved weeds found in cereals can now be killed with herbicides and with most, the farmer has a choice of chemicals.

Two more new products are now available and these have several advantages over other herbicides.

Control Of Wild Oats, J G. Paterson

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

WILD OATS are widespread throughout the world.

Their importance can be gauged from the fact that in the wheat growing areas of Canada and the U.S.A. some 60 million acres are infested.

Two chemicals are now available for the control of wild oats in wheat. This article compares their relative merits and gives recommendations for their use.

The Control Of Doublegee, Geoffrey A. Pearce

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

FOUR years ago no practical recommendations could be made for the control of doublegee.

With money provided by the State Wheat Research Fund, research has been undertaken into the control of this weed, and there is now no reason why most farmers cannot bring doublegee under control.

Watch Out For Afghan Thistle, J G. Paterson

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

ALTHOUGH known throughout the cereal and sheep districts of Western Australia as Afghan thistle, this plant is not really a thistle at all.

It belongs to the large botanical family of the Solonaceae and is closely related to the garden vegetables tomato and potato.

Linuron : A Success In 1966?, Geoffrey A. Pearce

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

Although some of the farmers who used linuron last year reported poor results, there is little doubt that this is the best herbicide since the advent of 2,4-D for weed control in cereals. This article gives the reasons for failure in some of last season's crops, and recommendations for use of linuron in 1967.
