Pesticide Use And Toxicology In Relation To Wildlife: Organophosphorus And Carbamate , Compounds, Gregory J. Smith, U.S. Department Of The Interior, Fish And Wildlife Service Jan 1987

Pesticide Use And Toxicology In Relation To Wildlife: Organophosphorus And Carbamate , Compounds, Gregory J. Smith, U.S. Department Of The Interior, Fish And Wildlife Service

All U.S. Government Documents (Utah Regional Depository)

The use of organophosphorus and carbamate pesticides has increased markedly during the past two decades. Currently, more than 100 different organophosphorus and carbamate chemicals are registered as the active ingredients in thousands of different pesticide products in the United States. More than 160 million acre-treatments of these pesticides are estimated to be applied to agricultural crops and forests each year. Clearly, these two groups of chemicals constitute a major portion of all pesticides used today. Organophosphorus and carbamate compounds have histories dating back long before their use as pesticides. Carbamates were developed during investigation of "ordeal" poisons used in Africa …

Integrated Pest Management On Rangeland: State Of The Art In The Sagebrush Ecosystem, Jerome A. Onsager, Usda, Agricultural Research Service Jan 1987

Integrated Pest Management On Rangeland: State Of The Art In The Sagebrush Ecosystem, Jerome A. Onsager, Usda, Agricultural Research Service

All U.S. Government Documents (Utah Regional Depository)

Several sagebrush communities represent optimum levels of negative development plant productivity for certain peculiar sites, and therefore should be managed for their preservation. Other sagebrush communities may be profitably modified to favor forage species that are more palatable to domestic livestock. Modification techniques can range from subtle (i.e., grazing strategies) to tracematic (i.e., brush removal and revegetation), and an associated spectrum of management tactics are described. Interrelationships between and problems associated with management of forage resources, management of weeds, and management of insects (including grasshoppers, black grass bugs, and beneficial insects) are discussed. Economical analyses, the role of modeling as …
