Efecto de benomyl en el desarrollo de mustia hilachosa causada por el hongo Thanatephorus cucumeris (Frank) Donk en cuatro variedades de frijol común (Phaseolus vulgaris L.)

Se realizó un estudio en la finca experimental La Compañía ubicada en el departamento de Carazo, Nicaragua, durante la época de primera de 1989. Con los objetivos siguientes; determinar la dosis de benomyl óptima en el control de la mustia hilachosa, Determinar la afectación de los rendimientos por efecto de la enfermedad en cuatro variedades de frijol común. Se obtuvieron 3 dosis de benomyl. 0.3, 0.6, 1.0 gramo por litro de agua y las variedades, 9ª. Talamanca, BAT 1155, Revolución 81 y Revolución 79A.. Los resultados mostraron que los porcentajes de severidad por la enfermedad alcanzaron hasta un 33 por ciento como máximo. Las dosis de Benomyl aplicadas para proteger el cultivo tuvieron un efecto marginal sobre la severidad de la enfermedad y los rendimientos. Así mismo estas aplicaciones no tuvieron efectos económicos. Talamanca y Revolución 81 presentaron menores porcentajes de severidad que BAT 1155 Revolución 79A.. Siendo Talamanca la variedad que obtuvo los más altos rendimientos, sin embargo fue la única variedad afectada por la enfermedad resultando una relación inversa entre severidad y rendimiento.

Hydrographic observations in Elkhorn Slough and Moss Landing Harbor, California, October 1970 to November 1971. Annual report, Part 3, July 1972

In October 1970, Moss Landing Marine Laboratories began an observational program to determine/the seasonal changes in the water chemistry of Elkhorn Slough and Moss Landing Harbor. This data report contains the first year of data (October 1970 - November 1971). These data are of immediate interest in determining the flushing and mixing mechanisms of the slough and in establishing the effect that local domestic and industrial effluents have on the distribution of these chemical parameters.

Water levels in artesian and nonartesian aquifers of Florida, 1971-72

The Department of Natural Resources, Bureau of Geology, is publishing as its Information Circular No. 85 the report entitled, "Water Levels in Artesian and Non-Artesian Aquifers of Florida, 1971-72," by Henry G. Healy, of the U. S. Geological Survey. In order to prevent future shortages developing from increasing demands, the present supplies of ground water must be properly appraised before they can be effectively utilized. Records of trends and fluctuations of ground water have long formed a basis for such an appraisal. (105 page document)

Air Flow Land-Sea-Air Interface: Monterey Bay, California - 1971. Annual Report, Part 1, July 1972

Air flow at the land-sea-air interface influences to a large extent the atmospheric conditions that determine the transport, di lution, and trapping of natural and man-made air pollutants in the coastal areas of Monterey Bay and the Salinas Valley. Analysis of the hourly air flow on a daily and monthly basis indicates patterns of stagnation from midnight to noon of the fol lowing day with moderate to strong air flow during period 1300 to 2200. Throughout the year 1971 whenever flow is greater than 5 mph, the prevailing wind direction is onshore and from a westerly direction. Suggestions for urbanization and industrialization are made on the basis of an understanding of the atmospheric conditions which lead to trapping and dispersal of atmospheric waste.

A Drift Card Study in Monterey Bay, California, September 1971 to April 1973: Annual Report, Part 4, 1973

Drift cards were released in Monterey Bay, California, to detect seasonal variations in the California Current system, and seasonal and diurnal wind variations in the immediate vicinity of the bay. About 23% of the cards were recovered, although the recovery rate varied from about 5% in the winter to about 60% in the late summer. Drift card speeds ranged from 1 to 8 km/day, in the winter and summer months respectively. Good agreement was observed between geostrophic current, wind, drogue, and drift card data, although drift cards were observed to be primarily wind driven. A weekend bias in drift card recoveries was observed for the entire period of study; however, it was less pronounced for those cards released during the summer months. Two bogus releases were used to estimate the discovery lag time, reported position accuracy, and longshore drift currents. Diurnal winds were observed during a 24-hour study, and indicated daily variations in the wind field may be as important as seasonal changes in moving surface water. The drift card speed was observed to be about 3% of the wind velocity, and 1 m/sec was estimated as the minimum effective wind. The wind factor, ranging from 2.2% to 4.0%, was used to estimate the actual paths of drift cards and to examine the role of diurnal winds in affecting surface water movement. (PDF contains 79 pages)
