Effects of different origins pesticides on sucking pest populations found in strawberry production field in derbent district of Konya province

In this study, effects of different origins pesticides on the populations Frankliniella occidentalis Pergande, (Thysanoptera: Thripidae) Tetranychus urticae Koch, (Aracnida: Acari) Chaetosiphon fragaefolii (Pentatrichopus) Cockerell'in (Hemiptera: Aphididae) were investigated. In addition, profit, yield and cost analysis of different pesticide applications were performed. The research was conducted between the years of 2016 and 2017 in an area of 1 acre in Derbent district of Konya. The study was designed according to the randomized block design. It was determined by the weekly flower, leaf and fruit sampling whether the harmful species exceed the economic loss thresholds. Treatments consist of environmentally friendly (K+) (Lecanicillium lecani, Azadiracthin, Paecilomyces fumosoroseus), conventional preparations (K-) (Deltamethrin, Abamectin, Imıdacloprid, Methomyl, Hexythiazox, Spirodiclofen+Abamectin, Thiacloprid) and control blocks. According to the results of the study, when the harmful populations in control blocks and applications in the (K+) and (K-) blocks compared, it was found that (K+) and (K-) applications in both years has a significant differences in confidence interval of 95% and reduces the harmful populations. As a result of the economic analyzes, strawberry production in 1 da area and (K +) application was realized as 214,053 kg, 216,129 kg in the (K-) application and 159,747 kg in the control blocks in which no application was performed. As a result of the analysis, it was determined that if the producers prefer environmentally friendly preparations instead of conventional preparations, they can attract harmful populations below the economic loss threshold and there will be no loss in yield in Derbent district. It is determined that strawberry growing is profitable in Derbent district for each treatment, as a result of reducing agrichemical prices and marketing opportunities at different prices, profit obtained from K+ application blocks will be higher.
