Control Of Weeds In Processing Peas, J G. Paterson

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

GROWERS of processing peas face many problems not the least of which is the control of weeds.

Crops which are to be harvested for canning or freezing must be practically weed free if good returns are to be obtained.

A summary of the results of trials carried out in 1962 to test recent developments in the chemical war against weeds in crops of processing peas.

Wild Oats In Wheat, J G. Paterson

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

Trials with a new chemical suggest that economical control of wild oats in wheat is only possible in heavily infested crops.

I N recent years there has been a marked increase in the incidence of wild oats in the wheat areas of this State. Three factors have been responsible.

Weed Problems In The Kimberleys, Rijn P J Van

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

AFTER fifteen years of irrigated agriculture, weeds have become a major problem at the Kimberley Research Station.

Since the Station is regarded as a type location for the potentially irrigable areas of the Ord River Valley, a similar problem is expected to arise when the surrounding areas have been under several years of commercial cropping.

An intensive study of weeds was therefore initiated at the Research Station in 1960.

The Effects Of Tillage Implements On Cereal Yields, H M. Fisher

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

Careful soil preparation is essential for cereal crops grown without fallow on clover ley land.

Crops give better yields where the land is broken up with a mouldboard or disc plough rather than a scarifier or similar machine.

The implements differ appreciably in their capacity to control weed growth and this is largely responsible for variations in cereal yields. "Takeall" disease is reduced by efficient weed control.

Cotton Growing On The Ord River, N J. Thomson

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

Cotton growing is nearing the commercial stages on the Ord River, with the first farm scale crops now ready to harvest on the Pilot farm, and the Kimberley Research Station.

It is already backed by some years of experimental work at K.R.S., which has provided the background for this article giving the first recommendations on cotton growing for future settlers in the Ord River Irrigation Area.

Weed Control In Cereals : Aerial Spraying Trials, G R W Meadly

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

SPRAYING cereal crops for weed control is now standard farming practice in Western Australia. Almost 500,000 acres of cereal crops, mainly wheat, are sprayed each year, and approximately three-quarters of this area is treated by aircraft.

Recent trials have shown that aerial application of 'extra low" volumes of hormone-like herbicides, with oil or water solvents, does not damage cereals if spraying is done at the right stage of growth.

Diseases Recorded On Cereals, Grasses And Pasture Legumes In Western Australia, S C. Chambers

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

This list constitutes a revision of portion of the census published by Came (1925) and supplemented by the same author in 1927.

It also contains records of diseases identified in the period between these earlier publications and December 31, 1959.

The list is divided into two sections, the first dealing with pasture legumes and the second with cereals and grasses.

The sections are arranged alphabetically according to the botanical names of the host plants. In general, the viral, bacterial, fungal and nematodal diseases and physiological disorders are listed in that order.

Seed Storage In Relation To Germination, G R W Meadly

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

WE are often asked how long seed can be stored and remain suitable for sowing.

There is no single answer as the period depends on a number of factors, including the type of seed, its condition at the time of storing and the nature of the storage.

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.
