The Effects Of Pre-Emergence Applications Of Simazine And Post-Emergence Applications Of Dalapon On Physio-Chemical Changes In Apple, Sour Cherry, Sweet Cherry, And Prunus Mahaleb, Jawad Thanoon Agha May 1968

The Effects Of Pre-Emergence Applications Of Simazine And Post-Emergence Applications Of Dalapon On Physio-Chemical Changes In Apple, Sour Cherry, Sweet Cherry, And Prunus Mahaleb, Jawad Thanoon Agha

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Simazine and dalapon have been used to control weeds in many crops during the last few years, but in 1963, when this study was begun, their uses in fruit orchards were limited. To study the effects of simazine and dalapon both on the control of weeds and on various metabolic changes in apple (Malis pumila), Montmorency sour cherry (Prunus cerasus), sweet cherry (Prunus avium), and Prunus mahaleb root stock, experiments were conducted from 1964 through 1966 in both the field and in the greenhouse.

The application of a low dosage of simazine (4 lb/A) to soil around twelve-year-old Montmorency sour …


A Study Of The Influence Of Petroleum Mulches On Several Herbicides With Selected Vegetable Crops, C. Linnis Mills May 1968

A Study Of The Influence Of Petroleum Mulches On Several Herbicides With Selected Vegetable Crops, C. Linnis Mills

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The effects of petroleum mulches on plant response to herbicides were studied at the Farmington Field Station. The herbicides were applied to the soil preemergent and by incorporation at one-half, normal and double the recommended rates with asphalt overlay. The herbicides and crops used were: Atrazine and Ramrod on sweet corn, PEBC and Diphenamid on tomatoes and EPTC and Trifluralin on snap beans.

Germination, overall crop rating, grass and broad leafed weed control and yields were measured. Data recorded from these trials showed that herbicides are as effective under the asphalt when compared to plots with herbicide but no asphalt. …


The Influence Of Petroleum Mulch On The Germination And Yield Of Tomatoes, Clarence Frank Williams May 1968

The Influence Of Petroleum Mulch On The Germination And Yield Of Tomatoes, Clarence Frank Williams

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The effects of petroleum mulches on the emergence and yield of tomatoes were studied at the Farmington Field Station, Greenville Field Station, North Logan, and the greenhouse. The mulches were applied as surface overlays above the seed or incorporating before planting.

Seedling emergence and yields were measured. Data recorded from trials conducted under cool weather conditions indicated that petroleum mulch overlays can be effective in increasing seedling emergence.

The increased seedling emergence with petroleum mulch is due to increased soil temperature, less moisture loss from the surface, and a minimum of soil crust formation.


Seasonal Lipid Content Of Bagworm Larvae, E. A. Heinrichs Apr 1968

Seasonal Lipid Content Of Bagworm Larvae, E. A. Heinrichs

Department of Entomology: Faculty Publications

It is common knowledge to many who have attempted to control bagworms Thyridopteryx sp., that early instars are fairly easy to control, while later larval stages are less susceptible to insecticides. Studies of other insects (Bennett and Thomas 1963, Munson and Gottlieb 1953, Munson et al. 1954, Reier et al. 1953) have shown that as the lipid content increases, the susceptibility to insecticides (especially chlorinated hydrocarbons) decreases. To determine whether the lipid content of the bagworm larva increased with age a series of lipid extractions was conducted.


Differential Plant Injury And Yield Responses Of Tomato Varieties To 2,4-D, D. P. Coyne, O. C. Burnside Feb 1968

Differential Plant Injury And Yield Responses Of Tomato Varieties To 2,4-D, D. P. Coyne, O. C. Burnside

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

Experiments reported in this bulletin were conducted to determine the extent of plant injury and yield loss due to high and low rates of 2,4-D sprays on a wide range of home garden and processing tomato varieties. Results of this study could be used as a basis for suggesting tomato varieties suitable for growing in areas where 2,4-D drift is a common problem. An experiment was also conducted to determine if there was resistance to or good recovery from 2,4-D injury in other tomato species and in a wide collection of tomato plant introductions.


Local Marketing Of Citrus Fruits, K T. Whitely Jan 1968

Local Marketing Of Citrus Fruits, K T. Whitely

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

CITRUS fruits are always popular on the local market but recently supplies from South Australia have made the market a very competitive one.

The situation demands the marketing of high quality citrus from growers in Western Australia.

The need to harvest the bulk of the Navel orange crop over a rather limited period and the resultant tendency for oversupply during that time also necessitates high standards of presentation to maintain firm prices.


Pressurised Soil Fumigation Equipment For Control Of Eelworm, C W. Robartson Jan 1968

Pressurised Soil Fumigation Equipment For Control Of Eelworm, C W. Robartson

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

THE treatment of soil infested with eelworms involves the use of chemical fumigants usually in the form of volatile liquids.

This article gives details for the construction of a simple pressurised fumigator which could be easily made by most orchardists, vignerons and market gardeners.

King Size Onions Not Wanted On The Local Market, M Hardie Jan 1968

King Size Onions Not Wanted On The Local Market, M Hardie

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

WESTERN AUSTRALIA produced 3,500 tons of onions in 1955 and 7,000 tons in 1964. This 100 per cent, increase was achieved with only a 39 per cent, increase in acreage, so that crops produced much higher yields.


A Survey Of Stone Fruit Plantings In Western Australia, Department Of Agriculture, Western Australia Jan 1968

A Survey Of Stone Fruit Plantings In Western Australia, Department Of Agriculture, Western Australia

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

This article presents the results of a survey of commercial stone fruit plantings in Western Australia, carried out by officers of the Department of Agriculture during 1966.

The main purpose of the survey was to provide varietal and other statistics not previously available in this State.

The results also give useful indications of future trends in the industry.


Chemical Thinning Of Plums And Peaches, J E L Cripps, K. T. Whitely Jan 1968

Chemical Thinning Of Plums And Peaches, J E L Cripps, K. T. Whitely

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

DURING the past decade the acreage of Japanese plums in Western Australia has increased by 10 percent, and production has risen by nearly 40 per cent.

Furthermore, almost 30 per cent, of our trees were still classified as non bearing in 1966, so rapid increases in production are certain to be recorded within the next few years.

The Carob Moth [Replaced By Farmnote 156/83.], P J. Michael

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

THE CAROB MOTH* was introduced from the Mediterranean region where it is an economic pest.

Under Western Australian conditions its importance is limited to almond crops although it occasionally attacks other fruits.


Production Costs In The Apple Industry : Comments On A Survey, A W. Hogstrom, I. J. Moncrieff Jan 1968

Production Costs In The Apple Industry : Comments On A Survey, A W. Hogstrom, I. J. Moncrieff

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

IN 1964 and 1965, light and heavy bearing years respectively, apples cost $2.40 per bushel to produce in Western Australia. This figure, to be considered with many other factors, was reached in a cost-of-production survey of 45 selected growers.

Packing and labour costs, in that order, were the two biggest cost-of-production items.

The Pear Leaf Blister Mite, G D. Rimes

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

THE pear leaf blister mite* may be causing widespread but undetected damage in Western Australian pear crops.

A bud-dwalling form exists which shows none of the leaf blisters normally associated with this species.
