Stop-Drop Sprays For Jonathan And Delicious Apples, N H. Shorter, J. Cripps

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

STOP-DROP sprays prevent excessive pre-harvest drop of Jonathan and Delicious apples.

Recent research has thrown more light on the best methods of employing these materials.

TWO CHEMICALS used as "stop-drop" sprays are available commercially in Western Australia. One of these, alpha napthalene acetic acid (NAA), is also well known as a thinning spray for apples.

A Survey Of Citrus Plantings In Western Australia, Frank Melville

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

THE development of the citrus industry in Western Australia has been determined by the requirements of the local market and there is no reason to suppose that this will not continue to be the controlling factor.

Fruit Growing In Western Australia, Western Australian Department Of Agriculture, Western Australian Tourist Development Authority

Horticulture published reports

Revised 1965.

The Mediterranean type climate of the coastal belt of the south-west of Western Australia is suitable for the commercial production of apples, pears, various stone fruits, oranges, grapes, and several other less important fruits. The warm dry summers (November-March), are too severe for the profitable production of many berry fruits and the winters too cool and wet for most tropical fruits. Figs, mulberries and olives all flourish in this climate but, for economic reasons, few are grown commercially.

A small tropical fruit industry, mainly bananas, has been established along the banks of the Gascoyne River at Carnarvon, which …

Root Growth Of Apple Trees, J E L Cripps

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

IT will surprise even experienced growers to know that an apple tree in W.A. needs twice the quantity of roots the same tree would need in a more temperate climate such as England's.

Early Hail Marks On Apples Do Not Grow Out, N H. Shorter, J. C. Rowbotham

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

ALTHOUGH the 1964/65 season brought a record crop with a good proportion of high quality fruit, the year was marred by several violent hailstorms in separate parts of the South-West.

Don't Neglect Bitter Pit Sprays, Department Of Agriculture, Western Australia

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

BITTER pit is a serious fault in export apples and each year considerable quantities of f r u i t are rejected for export on this account.

Now that control measures are available, it is most important that they be applied.

Citrus Water Spot, H L. Harvey

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

WATER SPOT is a disease condition which reduces the quality of citrus fruit in Western Australian orchards during continuous wet winter weather.

The problem is greatest in the Hills districts on navel oranges but mandarins may also be affected. Valencia oranges are rarely if ever affected.

Apple And Pear Growing In Western Australia : A Survey Of Trends In Planting, Frank Melville

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

APPLE growing is the major f r u i t growing activity in Western Australia.

The highest production recorded was 2,052,600 bushels in the peak year of 1960-61; of this 1,326,157 bushels were exported.

Western Australia is second only to Tasmania in the quantity exported and at present relies on overseas markets to absorb about two-thirds of the crop.

In 1962 there were 1,304,455 apple trees in this State and the average annual production over the previous five years was 1,449,962 bushels. *

Cross Pollination In Apple Orchards, N H. Shorter

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

ONE of the main aims of the successful apple grower is to reduce seasonal variations in cropping.

With this in view it has become apparent that provision for adequate cross pollination can be important in certain seasons, especially with Granny Smiths, if full advantage is to be taken of chemical thinning and other improved methods of orchard management.

Pruning Citrus Trees, D B. Argyle

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

PRUNING is one of the less important operations in citrus culture but if properly carried out it can contribute to the economy of production and the general wellbeing of the orchard.

The Mango In Western Australia, K S. Cole

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

ALTHOUGH normally considered a tropical tree, the mango does well in the sub tropics of Western Australia.

The main commercial area in the State is Carnarvon but a few trees grow as far south as Perth.

Pruning Citrus Trees. 2. Pruning The Mature Tree, D B. Argyle

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

EXAMINATION of a mature tree in full production will show the natural pattern of growth already explained.

It will be seen that over the years the frame has developed by a system of layers with new growth, stimulated by sunlight, constantly appearing on the top side of the older wood.

Eventually the terminal portions of the older layers are weakened by lack of light, they become unproductive and in turn adversely affect the general fruitfulness of the rest of the tree by shading and crowding.

Better Peach Varieties, Frank Melville

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

The PEACH is a very versatile fruit and a universal favourite. It is surprising then that the area of peaches in this State is very little different today to what it was 15 years ago. This is in spite of the fact that the population has increased by 48 per cent.

New peach varieties now under test could help satisfy the consumers' demand for a better range of high quality eating peaches— and expand the market for peaches in Western Australia.

The Pruning Of Fruit Trees : Deciduous Fruit Trees (Japanese Plums) (European Or English Plums), H R. Powell

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

Many varieties of Japanese plums are grown in this State, the main ones being Santa Rosa, Ruby Blood, Satsuma, Delaware, Wickson, Narrabeen, Elizabeth, Beauty and Wilson.

Citrus Psorosis, H L. Harvey

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

CAREFUL selection of propogating material will prevent the spread of citrus psorosis, a disease which reduces the yield and economic life of infected trees.

Citrus Growers : Don't Blow Up Your Colouring Rooms, Department Of Agriculture, Western Australia

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

THERE have been several dangerous incidents associated with the use of acetylene in citrus colouring chambers recently, and growers are warned to take care when using this explosive gas.

Brown Spot Of Passion Fruit, Department Of Agriculture, Western Australia

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

BROWN SPOT caused by the fungus Alternaria passiflorae, 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.

Chemical Thinning Of Apples, S E. Hardisty, N. H. Shorter

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

TWO important related problems of apple-growing in this State are biennial bearing and poor fruit size.

Early thinning by chemical means, is providing a valuable and practical means of tackling these problems.

With every prospect of heavy crops in most districts this year, many growers will be interested in the possibility of spray thinning.

The Fruit Industry In Other Lands. 5. The United States Of America (Continued), Frank Melville

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

THE United States grows in the vicinity of 64 million bushels of peaches, 83,000 tons of plums, 470,000 tons of prunes and 225,000 tons of apricots.

About half the peaches and the major portion of the plums, prunes and apricots are grown in California which is the centre of the canning industry.

There is also a large cherry industry concentrated mainly in the eastern side of the country. Production amounts to almost 100,000 tons of sweet cherries and 125,000 tons of sour varieties.

Hormone Sprays For Apricots, J E L Cripps

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

VARIOUS hormone sprays have been applied to apricots with the object of increasing fruit size and hastening maturity, and of these 245TA, the tri-ethanol amine salt of 245 trichlorophenoxyacetic acid, has in general, proved the most successful.

The increase in fruit diameter obtained with this spray in Western Australia has varied between 5 and 15 per cent, and is due to an increase in the size of the cells within the fruit, not to the production of a greater number of cells.

Bitter Pit : A Progress Report On The Use Of Calcium Nitrate Sprays For Its Control, Frank Melville, S. E. Hardisty

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

FREEDOM from serious pests and diseases such as Black Spot and Codling Moth and relative immunity from storage rots has greatly simplified apple growing in Western Australia.

However, what has been gained in this respect is often countered by pre-harvest and post-harvest physiological troubles which are rather common to apple growing in this State.

The Fruit Industry In Other Lands. 1. The United Kingdom, Frank Melville

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

THE following report deals with the many aspects of fruit growing both technical and commercial covered during a tour of three overseas countries undertaken on behalf of the Department of Agriculture and the fruitgrowers of Western Australia.

In the course of the three and a half months spent on this work, 13 research establishments were visited and contacts were made with research personnel both within these organisations and elsewhere.

Visits to commercial fruit growing areas were made with extension officers and these included brief visits to packing houses.

Altogether I had discussions with 127 research and extension personnel and industry …

Strawberries In Nebraska, C. C. Wiggans

Nebraska Agricultural Experiment Station: Historical Circulars

The strawberry is more widely grown than any other fruit in Nebraska and is the most valuable of the small fruits. Its total value is greater than that of any of the other fruit crops grown with the exception of apples, cherries, and grapes. It thrives well in all sections where moisture is not too limited and is found almost always in home gardens. It is also produced commercially to some extent, especially near the larger cities in the eastern end of the state.

Spraying Tree Fruits, C. C. Wiggans, E. H. Hoppert

Nebraska Agricultural Experiment Station: Historical Circulars

The production of sound, clean fruit is unquestionably one of the major problems facing the modern fruit grower. Culture may be neglected and pruning delayed for a time but the omission of sprays for even a single season demonstrates their absolute necessity. This applies equally to the commercial grower and to the farmer or gardener who has only a few trees.

Root Development Of Young Delicious Apple Trees As Affected By Soils And By Cultural Treatments, W. W. Yocum

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The major problem of this investigation was to determine the effects of different cultural treatments and soil conditions upon the depth and lateral spread of the root systems of young Delicious apple trees during the first three years in the orchard. This study was conducted during the years 1932 to 1934 inclusive.

The University Fruit Farm At Union, Nebraska, C. C. Wiggans

Nebraska Agricultural Experiment Station: Historical Circulars

The University Fruit Farm may be considered as a substation or detached portion of the Nebraska Experiment Station. It was established to assist in answering questions pertaining to fruit production, and only experiments of this sort are carried on. Supervision of this property rests with the Department of Horticulture of the Nebraska College of Agriculture. This circular has been prepared with the view of furnishing visitors to the farm with a brief outline of the experimental projects. Further information is available from either the local foreman or from the Department. Visitors are always welcome and helpful suggestions are solicited.

Bulletin 122 - Fruit-Fly: Description And Control, L. J. Newman

Bulletins 1 - 2999

IT is a fundamental principle of Economic Entomology that, in order to successfully combat an insect, the life history of that insect must be worked out. A feature common to all insects is a series of stages involving distinct changes of form which succeed each other in a definite order.

An insect like the fruit-fly affords no exception to this universal rule. Beginning with the fly, we have in regular succession—Egg, Larva, Pupa, and finally the fly again. These stages represent what is known as the life cycle of time insect. Each change—such as larva to pupa, pupa to fly—is …
