The Doublegee, G R W Meadly

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

DOUBLEGEE, like a number of other major weeds, is native to South Africa. It was introduced to Western Australia during the first years of settlement.

There is no more troublesome weed in Western Australia than doublegee. It competes strongly with crop and pasture and its spiny fruits penetrate the hoofs of stock, causing lameness.

Weeds In Lawns. 2. The Control Of Weeds In Lawns, Geoffrey A. Pearce

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

M OST lawns have weeds growing in them at some time during the year and in some lawns weed control becomes a major problem.

To the many people who like to keep a weed free turf it is therefore encouraging to know that nearly all weeds can be controlled with herbicides.

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.

Insect Pests Of Lawns., D G. Shedley

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

Lawns provide a home for many and varied insects. Although a large number do little or no damage there are some which, if left unchecked, will make it impossible to maintain the grass in good condition.

SPRAYING with insecticides is not always the best answer to pest problems. Manuring, cutting and watering must be maintained at proper levels. In fact, if this is not done the attacks of at least some pests will be more severe.

Vegetational Changes Of The Uinta Basin Since Settlement, Bernard Curtis Dastrup

Theses and Dissertations

A general survey of the vegetational changes of the rangelands of the Uinta Basin was made using historical records, documents, interviews, and recent vegetational surveys. Historical vegetatienal information about the Uinta Basin is very limited, most of it pertaining to the vegetation along the streams and rivers. Escalante, in 1776, mentioned the splendid groves of cottonwoods, the fine pastures, and the abundance of game along the rivers. Ashley in 1825 and Powell in 1870 entered the Basin via the Green River. Ashley crossed the Basin following the Duchesne River and its tributary the Strawberry River. He described the groves of …

Southeast South Dakota Experiment Farm Annual Progress Report, 1962, Q.S. Kingsley, F.E. Shubeck, Dwight Hovland, J.J. Bonnemann

Agricultural Experiment Station and Research Farm Annual Reports

This report marks the completion of the second year of research at this farm. Experimental work was continued in the areas of fertility and cultural practices, plant disease control, crop management, and crop variety testing. Investigations were expanded into corn plant populations, potassium deficiency, plant breeding and genetic studies on corn, grasses, legumes, sorghum and soybeans. Livestock research was initiated in the spring of 1962 when 106 feeder pigs were placed in three temporary buildings constructed for this purpose. Results of this trial are summarized in this report. Ninety(90) fall pigs have been started as a continuation of this experiment.

Some Factors Influencing The Response Of Halogeton Glomeratus To 2,4-Dichloropheloxyacetic Acid, Eugene H. Cronin

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Halogeton glomeratus (M. Bieb) C. A. Mey. was introduced into the cold desert of North America sometime prior to 1934. The first collections were made near Wells, Nevada in 1935 (Zappetini, 1953) and the plant now occupies in excess of 10 million acres. The plant is poisonous to livestock. The toxic substances in halogeton are sodium and potassium oxalates which account for 17 to 30 percent of its dry weight, depending on the time of year it is collected (Dye, 1956, and Williams, 1960a). Since the plant is a pioneer invader on disturbed sites in the salt-desert shrub vegetation of …

A Soil And Vegetation Inventory And Analysis Of Three Nebraska Sandhills Range Sites, Donald F. Burzlaff

Nebraska Agricultural Experiment Station: Historical Research Bulletins

This study was undertaken to inventory the soils and vegetation of certain areas of the Sandhills and to seek edaphic characteristics that may be the limiting factor in the distribution of various plant species. Information of this nature will permit formulation of more accurate management practices because of a refinement in delineation of range sites.

A Comparative Study Of The Species Of The Genus Crotaphytus Holbrook (Iquanidae), Wilbur Gerald Robison Jr., Wilmer W. Tanner

Brigham Young University Science Bulletin, Biological Series

The anterior musculature of C. wislizeni and C. collaris is described in detail and compared. Size and number relationships of the skull and its component bones, the sternum, the clavicle, the parts of the hyoid, the general body form, certain scales and teeth, and the eggs per clutch were determined for large samples of both species and then statistically compared. The general character of many structures is also compared and notes are made on C. reticulatus.

The differences encountered by this study, as well as the valid ones of those listed by Smith (1946:158–159) are not considered to be important …

Occurrence And Severity Of The Viruses Of Strawberry In Minnesota, T. H. King, Stephen C.Y. Liu, R. L. Skiles

Journal of the Minnesota Academy of Science

Approximately 900 plants of commercially grown strawberries of 45 varieties and experimental seedling selections were collected from various parts of the state of Minnesota and indexed for the presence of viruses. Their presence in these plants was demonstrated by the appearance of symptoms in the indicator plant, Fragaria vesca L., after they were inarch-grafted. 93 % of the plants indexed were virus-infected. Based on symptoms, the viruses have been classified into 14 symptomtypes. It was found that mottle and mild yellow-edge were the two dominant viruses, whereas crinkle and vein chlorosis were of rare occurrence. There was no indication that …

Webworm And The Weather, J A. Button

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

FOR many years farmers have remarked on the cyclic occurrence of webworm outbreaks in their cereal crops.

Webworm, the State's most serious pest of cereals, has frequently assumed a role of major importance for one or two seasons, and then not been troublesome for a number of years.

A research programme being carried out by the Entomology Branch aims to give a better understanding of the effects of weather conditions on the seasonal incidence of webworm, and should lead to more effective control of this pest.

Internal Decline Of Lemons, O M. Goss

Grazing To Control Pasture Composition, R A. Bettenay

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

APART from grazing management, there are a number of means by which the farmer can influence pasture composition.

With the exception of grazing, all of these processes involve recurring costs, so it is important to exert the utmost possible control through the grazing animal.

New Danger From Hoary Cress, G R W Meadly, R. D. Royce

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

HOARY CRESS is undoubtedly one of the worst weeds introduced into Australia. It is a vigorous deep rooted perennial which competes strongly with crop plants and seriously decreases yields.

The importance of three recent discoveries of this weed in Western Australia therefore need hardly be stressed.

G. R. W. Meadly, Offlcer-in-Charge of the Weeds and Seeds Branch, and R. D. Royce, Offlcer-in- Charge of the Botany Branch, report on two recently found infestations of hoary cross in the Great Southern, and one at Jerramongup.

An intensive eradication programme is under way.
