Pesticide Use On Crops In Nebraska - 1987, Maurice Baker, Nancy Peterson, Shripat T. Kamble
Pesticide Use On Crops In Nebraska - 1987, Maurice Baker, Nancy Peterson, Shripat T. Kamble
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
This is the third and most comprehensive study of pesticide use on crops in Nebraska. The first was completed in 1978 and the second one in 1982. The first study indicated that approximately 25 million pounds (11.34 million kg) of active ingredients were used on the major crops in Nebraska. This increased to approximately 30.2 million pounds (13.7 million kg) in 1982. The USDA requires accurate information to meet their responsibilities. Thus, this survey was undertaken to determine: 1) the use of pesticides on crops, pasture and rangeland and 2) to identify pest management practices.
Triazine Resistant Pigweeds In Kentucky Corn Fields, Jonathan D. Green, Michael Barett, Mike Radford
Triazine Resistant Pigweeds In Kentucky Corn Fields, Jonathan D. Green, Michael Barett, Mike Radford
Agronomy Notes
Smooth pigweed (Amaranthus hybridus) control from atrazine and/or simazine (Princep) has been unsatisfactory in some Kentucky corn fields. Many of these fields have grown corn where one or both of these herbicides have been used continuously for several years. These two triazine herbicides, particularly atrazine, are used annually on over 90% of the corn grown in Kentucky. Other areas in the U.S. and around the world have reported. unsatisfactory control from atrazine where triazine resistant pigweed has developed.
Evaluation Of Imazaquin, Imazethapyr & Postemergence Herbicide Combinations For Control Of Johnsongrass (Sorghum Halepense) In Soybeans (Glycine Max), Terry Mashburn
Masters Theses & Specialist Projects
Johnsongrass (Sorghum halepense) competition in soybeans (Glycine max) has adverse effects on soybean yields. Profitable soybean production in Kentucky and the Southeastern United States has depended upon good, cost effective johnsongrass control. Several herbicides have been developed to control johnsongrass in soybeans. Four of these recently developed compounds were imazaquin (2-[4,5-dihydro-4-methy1-4- (1-methyl-ethyl)-5-oxo-1H-imidazo1-2-y1]-3-quino1inecarboxy1ic acid), imazethapyr (+/-)-2-C4,5-dihydro-4-methy1-4-(1-methy. lethyl)-5-oxo-IH-imidazol-2-y1)-5-ethy1-3-pyridinecarboxylic acid, quizalofop 2-[4-[(6-chloro-2-quinoxalinyl) oxylphenoxyjpropaonic acid,ethyl ester, and analog of quizalofop (DPX Y6202-31).
Field experiments were conducted in 1986 to evaluate (a) the effectiveness of imazaquin and imazethapyr preplant incorporated, postemergence, or in combination with pendimethalin [N-(1-ethylpropy1)-3,4-dimethy1-2.6-dinitrobenzenamine], and (b) herbicide antagonism with fluazifop[butyl(R)-2-(4-[(5- trifluoromethy 1 …
Toward Better Minimum Tillage For South-Coastal Sandplain Soils, W L. Crabtree
Toward Better Minimum Tillage For South-Coastal Sandplain Soils, W L. Crabtree
Resource management technical reports
Seventeen farmers compared their conventional cropping practices with some form of minimum tillage cropping. The minimum tilled crops yielded 21 percent less grain than the conventionally sown crops. The reasons for these decreased yields were in most cases related to inexperienced management. The minimum tilled treatments usually had very poor weed kill strategies which often resulted in large weeds at sowing, very cloddy seed-beds, and numerous insects in the young crops.

Department of Plant Pathology: Faculty Publications
Improvement of the taxonomy of the genus Xanthomonas and especially of Xanthomonas campestris, which is subdivided into more than 125 pathovars, is discussed. Recent contributions to the taxonomy of Xanthomonas are reviewed, and on the basis of these data and unpublished data from several laboratories, the usefulness of different phenotypic, chemotaxonomic, and genotypic techniques is discussed. The heterogeneity of several X. campestris pathovars has been demonstrated by sodium dodecyl sulfate electrophoresis of whole-cell proteins and fatty acid fingerprinting. The host selectivity of the pathovars is not correlated with their relationships as revealed by DNA-DNA hybridization experiments. In order to …
Life History Of Paracantha Gentilis (Diptera: Tephritidae), David H. Headrick, Richard D. Goeden
Life History Of Paracantha Gentilis (Diptera: Tephritidae), David H. Headrick, Richard D. Goeden
Horticulture and Crop Science
The life history of Paracantha gentilis Hering in southern California is described. This stenophagous tephritid reproduces in the capitula of native Cirsium thistles. Courtship and mating behavior are described from field and laboratory observations. Territorial and courtship behavior of males and the morphological characters involved in possible male pheromone emission are described and illustrated, as are the oviposition behavior and reproductive morphology of females. Egg clutch sizes ranged from one to 13 eggs, with a maximum of six clutches per capitulum. Larvae fed gregariously within stage-specific niches. Pupariation occurred in the capitula, from which adults emerged in mid-June through early …
Automated Harvesting Of Burley Tobacco I. System Development, Larry G. Wells, George B. Day V, Timothy D. Smith
Automated Harvesting Of Burley Tobacco I. System Development, Larry G. Wells, George B. Day V, Timothy D. Smith
Biosystems and Agricultural Engineering Faculty Publications
A fully automated system for harvesting and handling mature buriey tobacco has been developed. This article identifies the operations essential to this harvesting concept and describes the development of the mechanisms by which they were accomplished. The system detaches, inverts and places mature plants into portable holders for air curing under waterproof covering without requiring any manual handling of the crop. Manual labor currently required to harvest buriey tobacco would be reduced by 80-85% and the system would eliminate the drudgery associated with manual handling. The harvesting system has an approximate capacity of 1.4 to 2.0 ha/day (3.5 to 5.0 …
Automated Harvesting Of Burley Tobacco Ii. Evaluation Of System Performance, Larry G. Wells, George B. Day V, Timothy D. Smith
Automated Harvesting Of Burley Tobacco Ii. Evaluation Of System Performance, Larry G. Wells, George B. Day V, Timothy D. Smith
Biosystems and Agricultural Engineering Faculty Publications
A prototype system for fully automated harvesting of burley tobacco has been developed and tested. Three years of field testing has shown that mechanical losses associated with the system were only slightly higher than via conventional methods. The system performed reliably at a sustained harvesting rate of approximately 1.4 ha/day (3.4 acre/day), while indicating that a rate of 2 ha/day (5 acre/day) should be easily achievable. The system is operated by two workers and reduces conventional labor requirement by approximately 80-85%.

The Effects Of Within-Row Spacings & Cultivars On The Yield Of Bush Snap Beans (Phaseolus Vulgaris L.), Timothy Hafner
The Effects Of Within-Row Spacings & Cultivars On The Yield Of Bush Snap Beans (Phaseolus Vulgaris L.), Timothy Hafner
Masters Theses & Specialist Projects
The effects of within-row spacings and cultivars on the yield of bush snap beans (Phaseolus vulgaris L.) were studied in two experiments. In each experiment, two cultivars and four within-row spacings (8, 15, 23 and 30 cm) were arranged in a split-plot with four replications. Spacing treatments were the whole plots and cultivars were the split plots. In 1988, the two cultivars were 'Blue Lake 274' and 'White Half Runner'. In 1989, the cultivars were 'Blue Lake 274' and 'Kentucky Wonder 125'. All rows were spaced 91 cm apart. Pods were harvested and oven dried. The data were subjected …

B830: An Atlas Of The Native Woody Plants Of Maine: A Revision Of The Hyland Maps, Janet S. Mcmahon, George L. Jacobson Jr., Fay Hyland
Bulletins
In 1944 Fay Hyland and Ferdinand Steinmetz published The Woody Plants of Maine: Their Occurrence and Distribution. This small bulletin catalogs the state's native and exotic trees, shrubs, and woody vines. In-state distributions are given for 513 taxa, including 366 species, Ill varieties and named forms, and 36 hybrids. Hyland collected information for this comprehensive work from three sources: a systematic field survey of the state which he personally conducted between 1933 and 1939; a review of botanical publications on Maine flora; and herbarium records from the New England Botanical Club, Gray Herbarium, Arnold Arboretum, the Boston Society of …
An Autecological Study Of Pyxidanthera Barbulata In The Blackwater Ecologic Preserve Virginia, John Marc Lowenthal
An Autecological Study Of Pyxidanthera Barbulata In The Blackwater Ecologic Preserve Virginia, John Marc Lowenthal
Biological Sciences Theses & Dissertations
Pyxidanthera barbulata (pyxie moss), a rare and endangered subshrub, has been found in decreasing numbers in it's "pine barren" habitat. An autecological study encompassing vegetation association analysis and environmental measurements was performed in the Blackwater Ecologic Preserve, its only known location in Virginia. The preserve is being subjected to controlled burning and the effect of burning on the species was evaluated. A multivariate analysis of variance was performed to identify species associations, and simple analysis of variance was done to find trends in the environmental data. Four taxa were positively associated with P. barbulata, Gaultheria procumbens, Vaccinium tenellum, Cladonia spp., …
