Impact of Folimat (800) (Organophosphate) and Icarose Pesticides on Soil Fertility and Garden Rocket (Eruca Sativa) Growth

Abstract

An experiment was carried out at Shambat Agricultural Farm, College of Agricultural Studies, Sudan University of Science and Technology on December 2014 for one season to study the impact of Folimat and Icarose pesticides on soil and garden rocket growth. Both pesticides were added at concentration of 1.92kg/ha (recommended dose) and 2.88kg/ha (excessive dose) for Folimat and for Icarose 249.2ml/ha (recommended dose) and 371.8ml/ha (excessive dose) in addition to control to evaluate their effect on plant and soil. Measurements taken were plant height, leaf area and fresh and dry weight. pH, total nitrogen %, phosphorous (ppm), soluble cations, Ca+, Mg++, K+ (Mg/L), soluble anions CO3, HCO3, Cl, CaCO3 (Mg/L) electrical conductivity of the saturation extract ECe ds/m. The two pesticides were applied one month after planting. The results revealed that both chemicals affected positively garden rocket vegetative growth at the recommended dose but negatively at the excessive dose. Both pesticides reduced some measured soil characteristics. Key words: Folimat, Icarose, pesticides.
