Common bean yielding components affected by systemic insecticide application

The main purpose of this research work carried out in 1994 at the Federal University of Viçosa, State of Minas Gerais, Brazil, was to determine the effects of systemic insecticides on several common bean (Phaseolus vulgaris L.) yielding components. Life tables have been developed based on mortality rates as well as the effects of soil application of systemic insecticides on several traits (plant height and plant mortality; nodule, flower and bean average numbers; percentage of damaged grains). Aldicarb 150 G and Phostiazate revealed no significant effects on plant height and average nodule number. The highest damage levels were recorded in beans - infestation by Etiella zinckenella (Treitschke) (Lepidoptera: Pyralidae); due to high plant mortality rates during the vegetative period and to grain losses (caused by Colletotrichum lindemuthianum). Total damage was primarily due to flower abortion.
