A Survey Of The State Of Utah For Areas Infested With The Stem Nematode Of Alfalfa, Dwayne R. Buxton

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Plant nematodes belong to a large group of invertebrates known as round worms, They derive their name from the Greek word "nema," meaning thread. In literature some authors refer to nematodes as nemas. In England and many parts of the United States, plant-parasitic nematodes are called eelworms.

While some damage to plants results from mechanical injury, salivary secretions injected by the nematode into the plant are usually the major cause of damage. Experiments conducted in the first part of the present century have demonstrated large differences in plant growth in soil infested with nematodes and soil freed of nematodes by …

Appraisal For Combined Pea Aphid And Spotted Alfalfa Aphid Resistance In Alfalfa, W. L. Howe, W. R. Kehr, C. O. Calkins

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Sources of combined resistance to spotted alfalfa and pea aphids were found in Ranger alfalfa and its parental strains, foreign plant introductions, clones and their progenies. Ranger alfalfa appeared to be a good source for selection of plants with resistance to both aphids.

Observations On The Biology, Anatomy, And Morphology Of Otobius Lagophilus Cooley And Kohls, C. Selby Herring, D Elden Beck

Brigham Young University Science Bulletin, Biological Series

The principal objective of this study is to bring up to date information on geographic distribution, seasonal occurrence, and host-parasite relationship of O. lagophilus in western North America. Notes on life history and disease transmission potential are included.

Data and information were obtained from three sources: (1) natural history collections and field records at Brigham Young University over the past twenty years; (2) the Rocky Mountain Laboratory in Hamilton, Montana; and (3) published literature.

All available collection records are presented in a table from which information on geographic distribution, seasonal occurrence, and host-parasite relationship was extracted. O. lagophilus is known …

Cacodylic Acid As A Silvicide, Maurice W. Day

Aspen Bibliography

This report deals with the effectiveness of cacodylic acid (dimethylarsenic acid) as a silvicide for undesirable trees. Cacodylic acid has been used successfully as an herbicide for the destruction of grasses and weeds. Experimental work with this material was begun during the 1963 field season, and continued during 1964, to permit complete evaluation of the results. It appears that cacodylic acid has considerable potential as a silvicide.

Tenebrionidae Beetles Of The Nevada Test Site, Vasco M. Tanner, Willis A. Packham

Brigham Young University Science Bulletin, Biological Series

The intent of this study conducted over a period of three years was to ( 1 ) provide descriptions of the species of tenebrionids found at the Nevada Test Site, (2) determine their relative abundance, (3) determine their seasonal activity, and (4) ascertain their plant community relationships.

A total of 14,650 beetles representing 46 kinds of tenebrionids was collected with sunken can traps, by hand, and ultra-violet light. Collections were made at regular intervals in the following plant communities: Larrea-Franseria, Lycium, Atriplex-Kochia, Grayia-Lycium (disturbed and undisturbed areas), Salsola, Coleogyne, Pinyon-Juniper, and Mixed.

The data obtained from this study indicate that …

Cytoplasmic Male Sterility And Intergrafts Between Lycopersicon Esculentum And Solanum Pennellii Corr., W. R. Andersen

Journal of the Minnesota Academy of Science

Attempts to transmit cytoplasmic male sterility through intergrafts between Lycopersicon esculenfum and Solanum pennellii have been unsuccessful. This implies that in these materials, the factor conditioning cytoplasmic male sterility is noninfective. The results of this study and other similar studies by other workers suggest the possibility that grafting might be used as a tool in the classification of cytoplasmic factors affecting mole sterility in plants.

Variations In Porphyrin Content In Root Nodules, Marie H. Berg

Journal of the Minnesota Academy of Science

The root nodules of a series of legumes were investigated with and without inoculum in sterilized growing material as well as in open soil to find plants that synthesize extractable amounts of porphyrins. These experiments were a preliminary study toward the investigation of the influence of heavy metal salts on the increased production of porphyrins.

The Wild Celery Of Christmas Lake, Hibbert Hill

Journal of the Minnesota Academy of Science

The growth and reproduction of Vallisneria as seen and photographed below water in Christmas Lake, Hennepin County, Minnesota, is described. The functions of the water surface film, of wave energy, and of the coiled stem of the pistillate flower, in fertilization is discussed. It is found that many of the plants grow in such depths that fertilization is impossible.

Sheep Can Be More Profitable In The Wheatbelt, G T. Halpin, P. Nelson

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

TRADITIONALLY, wheatbelt farmers have looked upon sheep as being subsidiary, or at best, complementary to their main activity, wheat growing.

Because there has been a mistaken belief that clover would not grow, these farmers have depended upon native grasses and crop remains (stubble) for sheep feed, a practice which has put a limit to the number of sheep a property could support.

Time Of Lambing At Esperance, R J. Doyle

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

ESPERANCE is one of the few places in Western Australia at which experiments over three years have shown a definite improvement in number of lambs produced to marking, as a result of lambing in the August-September period.

The Black Beetle, Clee Francis Howard Jenkins

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

Since first reported in Western Australia 27 years ago, the black beetle has spread widely to become a well-known pest in metropolitan home lawns and public grassed areas.

THE black beetle (Heteronychus sanctae-helenae Blanchard) is a native of South Africa which seems to have first gained a footing in Australia in about 1930, for it was then recorded as a pest of maize in New South Wales. (Gurney 1934).

Weed Control : Cotton Fireweed, Department Of Agriculture, Western Australia

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

COTTON FIREWEED is a native perennial plant which has developed as a serious weed in the south coastal areas.

Being a perennial it makes quick, active growth following summer rains and rapidly outgrows annual pasture plants.
