The Naturalised And Cultivated Annual Medics Of Western Australia, B J. Quinlivan

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

Lot Feeding Of Beef Cattle. 5. Feed Lots And Animal Health, W J O Wilkie

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

BRINGING cattle from various sources together in a feed lot makes them more liable to disease than they would be in the open paddock.

Vegetable Seed Treatments, G C. Macnish

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

Many common vegetable diseases can be carried over from one crop to the next by means of contaminated seed.

The use of such seed also results in contamination of the soil with the disease-causing organisms.

Prevention or control of seed-bome diseases can be achieved by the use of appropriate chemical or hot water treatments.

Blossom-End Rot Of Tomatoes, G C. Macnish

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

Complete control of this common physiological disorder of tomatoes cannot as yet be achieved, but a number of measures can be employed to reduce its incidence.

DURING the summer months many tomato specimens are received showing symptoms of blossom-end rot.

Many growers attribute this trouble to parasitic organisms and are anxious to prevent it spreading to the rest of their crop.

However as blossom-end rot is not a parasitic disease, it cannot be controlled by fungicidal or bactericidal sprays.

Brown Spot Of Passion Fruit, R F. Doepel

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

Brown Spot is a serious fungal disease of passion fruit in this State.

Successful crop production is dependent on adequate disease control in the plantation.

BROWN SPOT is found in plantings throughout Western Australia. Severe outbreaks of the disease have occurred in most districts, including Serpentine, Manjimup, Nannup and Denmark.

Although isolated young plantings may remain healthy for two or three years, the disease eventually becomes established in the vines.

Insect Pests Of Cotton In The Ord River Irrigation Area, K T. Richards

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

COTTON is grown in the Ord Valley of north Western Australia, mainly as an annual, irrigated crop during the hot summer months of the "wet season".

It is usually planted in November-December and harvested March-May.

This period of growth corresponds closely to that of maximum insect activity.

Weaning Lambs Under Pastoral Conditions, H Suijdendorp, L. Parsons

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

IN the summer rainfall region of the pastoral areas lambs are too often born too late to ensure their survival.

In good seasons with a fair measure of winter rain more late lambs will survive, but losses are still serious. The only solution to this problem is to make sure lambs drop in May-June.

But the presence of late and often unmarked lambs at mating time is a disturbing influence, which makes it hard to advance the established mating pattern.

Watch Out For Wild Oats, J G. Paterson

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

SINCE the publication of the results of trials with Carbyne* on wild oats in cereal crops several enquiries have been received from farmers whose crops have been heavily infested with the weed.

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

APRICOTS are grown in this State mainly for the fresh fruit market. Varieties commonly grown include Newcastle Early, Royal, Ouillins Early, Blenheim, Moorpark, Trevatt and Tilton.

In some orchards the trees are regularly pruned, but in others they are left unpruned. Unpruned trees are given some renovation pruning from time to time.

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

ROSES are among the most popular and versatile ornamentals as they may be grown as climbers, bushes or standards.

Black Spot of roses can be prevented by combining good sanitary practices with the regular use of preventative fungicides such as maneb and folpet.

Range Feeding Of Cotton By-Products In The Kimberleys, John Hubert Auty

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

Commercial cotton production has started in the Ord River area and by-products of the industry will soon be available for stock feeding in the surrounding pastoral areas.

Cotton seed and cotton seed meal will cause digestive upsets if fed in any quantity to horses, poultry or pigs.

Ruminants have no trouble in handling the material and the Kununurra ginnery could supply a useful protein supplement for Kimberley cattle.

The Causes And Control Of Infertility Of Rams, J Craig

RESULTS of 1963-64 linseed variety trials are available for four trials on research stations and for four trials on farmers' properties.

These are shown in the table below. Excellent yields were obtained at some sites, while disappointing results were obtained at Chapman and Esperance.

Poor results at Esperance were due to the poor finish to the season.

The Effect Of Mulesing And Tailstripping At Lamb Marking On Subsequent Lamb Growth And Incidence Of Fly Strike, R J. Lightfoot, W. L. Mcgarry

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

THE modified mules and tailstrip operation has been shown to be highly effective in reducing the incidence of crutch strike in sheep.

In Western Australia the operation is usually performed on ewe weaners or hoggets immediately after either crutching or shearing.

Plant Diseases : Angular Leaf Spot Of Cucurbits, O M. Goss

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

ANGULAR leaf spot caused by the bactterium Pseudomonas lachrymans (E.F.Sm. & Bryan) Carsner, is common on cucumbers and gherkins grown late in the season.

The same disease has been recorded on rockmelons, watermelons and pumpkins but rarely occurs on these hosts in Western Australia.
