Integrated pest management of Okra insect pests

Field study on integrated pest management of Okra insect pests was carried out at experimental area of Faculty of Crop Protection, Sindh Agriculture University, Tandojam during the year 2016. The okra crop variety Rama Krishma was sown on RCBD with three replications by drilling method along agronomical practices. The results revealed that the reduced pest population of jassid, aphid and white fly after different IPM treatments on okra crop except control. Treatments were applied T1 (Biosal applications), T2 (Tobacco extract application), T3 (Natural enemies) T4 (Conventional farming practices) and T5 (untreated plots). The pest population of jassid, aphid and white fly also decreased gradually after each spray except control treatment. The post treatment observations were taken after 48 hours each spray respectively. The results indicated that the lowest mean pest population of Jassid (1.84), aphid (2.07) and white fly (0.31) per leaf was recorded on T1 (Biosal application), followed by population of jassid (1.93), aphid (2.18) and white fly (0.42) per leaf which was noted from T2 (Tobacco extract). However, moderate population of jassid (2.03), aphid (2.23) and white fly (0.43) per leaf was obtained from T3 (Natural enemies) as well second moderate pest population of jassid (2.06), aphid (2.36) and white fly (0.49) was recorded in T4 (conventional farming practices). Moreover, highest pest population of jassid (2.15), aphid (2.42) and white fly (0.57) per leaf was observed on T5 untreated plots (control). Furthermore the results revealed that in T1 (biosal application) reduced pest population was recorded other than rest of other treatments as well in control treatment. The post treatment of biosal applications found to be more effective as compared to other treatments.
