Determination of Spraying Residue Amounts and Values of Distribution Uniformity The Agricultural Enterprises Conditions for Sunnpest Spraying

Abstract

This study has been carried out in the villages located within the towns of Siverek,Viransehir and Hilvanin Sanlıurfa city where sunnpest damage is commonly applied. The use of planes in struggling withsunnpest have became important because the wheat fields cover large areas and sunnpest damages thecrop production in a very short time period and also because of the existing topographycal conditions. Onthe other hand, as paralel to developments in the world, chemical use against to sunnpest has beenbanned since 2006 due to the problems faced, i.e. negative impacts on environment, when usingagricultural plane. The use of manual equipments for chemical application against sunnpest was thereforedecided in Turkey. Untill 2006, monitorization and protection were carried out by plant protectionagencies of agriculture ministry located in the city or towns, as a result, practical knowlodge andexperiences of farmers on this matter had been unsufficient. While field experiments was carried inagricultural enterprises conditions, it was found that spraying per unit surface residue amounts anddistribution uniformity values were determined for sunnpest spraying. In the field experiments, maximumand minimum spraying residues per square centimeter (µg cm-2 ) was found ranged from 0.37 to 1.84, 0.23to 1.21 and 0.23 to 0.76, respectively for wheat of head, mid and sub levels.
