Determination Of Toxicity And Bioactivity Of Four Organic Insecticides Recommended For Control Of Pests In Vegetable Crops, Hugo Humberto Rodriguez Salvatierra

Theses and Dissertations

This work was done to determine the toxicity and bioactivity of four organic insecticides and ultimately find answers about their toxic potential. Thus, farmers will be able to take the necessary precautions when using them. This investigation was performed in the Laboratory of Biology of the Eastern University Center (Chiquimula) at the University of San Carlos, Guatemala. In order to determine the acute toxicity and bioactivity of the organic insecticides ANONAZO, BOX, AJORIN, and NARCISO, five doses were used in albino mice and three concentrations in nauplii of brine shrimp (Artemia salina). The finney basic program was used for calculating …
