According to findings, statistical connection was determinated between the number of <em>P.hordei </em> at square meter (m <sup>2 </sup>) and 10 sweep net. This connection was evaluated as important. The regression estimation equation was found as y= 4.84+0.768x. It was determinated to could be use of the sweep net counting method instead of square meter (m <sup>2 </sup>) method taking into consideration the weather conditions. Also if is accepted that; this method can be safely and easily used in research and application studies.}, number={1}, publisher={TARIM VE ORMAN BAKANLIĞI EĞİTİM VE YAYIN DAİRESİ BAŞKANLIĞI}
