  • Integration of Biological Control Into Ipm Systems for Aquatic Weeds
    INTEGRATION OF BIOLOGICAL CONTROL INTO IPM SYSTEMS FOR AQUATIC WEEDS James J. Marois, Department of Plant Pathology, University of California, Davis, CA 95616 USA ABSTRACT The development of effective long-term control programs for aquatic weeds is dependent upon the ability to integrate biological, chemical, and cultural control strategies. Successful IPM programs are dependent upon a sound knowledge of the cropping system (especially the inputs and outputs of the system), the biology of the aquatic weed pest, and the biology of the control agent(s). There are several ways to analyze these complex systems, from the molecular to the community level. This presentation will emphasize the ecological interactions that should be con- sidered. INTRODUCTION approach may be to augment or inundate the system with the control organisms at specific times in the Integration of biological control of paddy and cropping history. This is especially true when the aquatic weeds into integrated pest management control agent is a fungus or bacterium, since these programs is a necessary goal for the implementation are relatively easy to produce in large quantities and of sustainable rice production systems. To reach are dependent upon specific environmental this goal, however, a number of obstacles must be conditions for greatest efficacy. When a fungus is overcome.

  • Toxicity and Hazard of Pesticides
    Pesticide Toxicity and Hazard April, 2017 Introduction Pesticide applicators should understand the hazards and risks associated with the pesticides they use. Pesticides vary greatly in toxicity. Toxicity depends on the chemical and physical properties of a substance, and may be defined as the quality of being poisonous or harmful to animals or plants. Pesticides have many different modes of action, but in general cause biochemical changes which interfere with normal cell functions. The toxicity of any compound is related to the dose. A highly toxic substance causes severe symptoms of poisoning with small doses. A substance with a low toxicity generally requires large doses to produce mild symptoms. Even common substances like coffee or salt become poisons if large amounts are consumed. Toxicity can be either acute or chronic. Acute toxicity is the ability of a substance to cause harmful effects which develop rapidly following exposure, i.e. a few hours or a day. Chronic toxicity is the ability of a substance to cause adverse health effects resulting from long-term exposure to a substance. There is a great range in the toxicity of pesticides to humans. The relative hazard of a pesticide is dependent upon the toxicity of the pesticide, the dose and the length of time exposed. The hazard in using a pesticide is related to the likelihood of exposure to harmful amounts of the pesticide. The toxicity of a pesticide can’t be changed but the risk of exposure can be reduced with the use of proper personal protective equipment (PPE), proper handling and application procedures. Pesticide Toxicity Some pesticides are dangerous after one large dose (acute toxicity).
