Comparison of Biopesticides and Synthetic Insecticides against Citrus Psylla (Diaphorina citri) in Citrus Orchad Rabbat District Dir Lower

Abstract

The research was conducted at Citrus Orchard, Rabbat district Dir Lower to examine the impact of neem seed extract biopesticides and synthetic insecticides on Diaphorina citri in 2020. Biopesticides acts as active chemical against antifungal and insecticides which control stress of pathogen and biotic stresses in harvest stage of fruits. The experiment consisted of five treatments neem seeds extract, cypermethrin, indoxacarb, bifenthrin, and a control. Five plants were chosen in citrus orchard with was divide into four sections followed by complete design RCB. Five leaves were sampled from each branch and the selected pesticide provided faster and effective control compared to botanical extract. During the study, cypermethrin, indoxacarb, bifenthrin, and neem seeds extract were used against Citrus psylla, while the control plants were left untreated for comparison. The results showed that among all the tested chemicals like cypermethrin, bifenthrin, indoxacarb including the botanical extract. The result showed that bifenthrin was found to be the most effective in controlling the pest, followed by indoxacarb, cypermethrin, and the botanical extract of neem seed. According to study that highest population density was recorded in tree1 as compared to tree 2 while lowest in tree 5. C. psylla observed after the 24 hours of treatment showed similar effect while the neem extract was lit bit toxic compared to other biopesticides. The C. psylla after the treatment of 3 days showed  that  the cypermethrin, indoxacarb and bifenthrin was same in ratio (1%) as follow by Neem, sample 1 and sample 2 was same in numbers (2%) than sample 3 and sample 4 was similar too (1%). Additionally, the field experiment confirmed the superiority of bifenthrin over the botanical extract.
