Abstract

Bean is one of the most important crops because it is a staple food. In order to control diseases and pests, the use of fungicides and insecticides in the seed treatment are efficient methods. In this sense, the aim of this study was to evaluate the effect of fungicides and insecticides on physiological quality of bean seeds. The experiment was conducted in a laboratory and greenhouse, and seeds of two genotypes of common bean (Peanut and Xamego) were used. The seeds were treated with the following fungicides: Captan, Fluazinam, Metioram and insecticides: Acefate, Imidacloprid and Thiametoxan. The experiment was arranged in a completely randomized design, with replications and seven treatments. Not treated seeds were utilized as control. The bean seeds treatment of the genotype Peanut and Xamego using insecticide and fungicide did not affect the physiological quality of the seeds. Xamego genotypes shows greater vigor in the laboratory, while the Peanut genotype in the greenhouse, and the treatments do not interfere in the initial growth of the plants.

Key words: Phaseolus vulgaris L, germination, phytosanitary treatment, seedling emergence, vigor.
