“…The study findings are in line with the results reported by previous workers (Rehman et al, 2015). The application of botanical extracts and chemical insecticides can influence insect pest population and total fruit weight (Ali et al, 2005;Indira Gandhi et al, 2006).…”

The Jassid, Amarasca bigutulla bigutullaa is an important sucking pest of the okra crop. An experimental study was conducted during 2018 to check the comparative toxicity of nitenpyrem and neem oil against jassid under okra field conditions. The study revealed that 24 hours after treatment, nitenpyrem was found more toxic and effective with maximum reduction of jassid population (72.15%). Whereas, 120 hours after treatment with 4% neem oil, 15.05% jassid reduction was observed. The mortality rate of the jassid was increased with increasing in time after application of chemical insecticides. The study concluded that insecticide was most toxic and gives higher mortality of jassid as compared to neem oil.

The purpose of this study was to measure the effect of chemicals against Okra fruit borer. The use of chemicals against Okra fruit borer was studied in Nuclear Institute for Food and Agriculture (NIFA) Tarnab, Peshawar 2009. The plots were randomly selected for treatments. The chemicals used against Okra fruit borer were Nucleo Polyhydrosis virus (NPV), Peskil and Neem Seed Water Extract (NSWE). Among these Nucleo Polyhydrosis Virus (NPV) showed highly significant results against Okra fruit borer followed by Peskil and NSWE. It can be concluded that Nucleo Polyhydrosis Virus (NPV), Peskil and aqueous extracts of NSWE all have shown synergetic effect along the resistant Okra cultivars against Okra fruit borer and greatly increase the Okra yield parameters. Application of Nucleo Polyhydrosis Virus (NPV), Peskil and aqueous extracts of NSWE alongside sowing resistant Okra cultivars would give a more effective management of Okra fruit borer and higher yields of Okra fruit. Okra (Hibiscus esculentus L.) Commonly known as bhindi or lady's finger belong to family Malvaceae. This genus of okra contains more than 140 species [1,2]. In Pakistan okra is grown in summer the area under cultivation is 232.05 hectares with the production of 303.16 tons per year [3]. Okra as a human food contains protein, vitamins, carbohydrate, fat, calcium, potassium and other mineral matters which are often lacking in the diet of developing countries.

Background: Natural farming (NF) is a farming system that uses environmentally friendly pest and disease management practices. In contrast to chemical farming, it avoids use of synthetic fertilizers, pesticides and fungicides and hence, offers an alternative way for the eco-friendly pest management for the sustainable crop production. French bean crop is ravaged by wide array of insect pests wherein, sucking insect-pests like aphids, leaf miner and pod borer causing considerable damage. To manage these pests, farmers are spraying both recommended and non-recommended synthetic chemical pesticides having adverse effects on environment and human beings. Methods: Field experiment was conducted to evaluate the pest management strategies against sucking insect-pests and pod borer infesting French bean over a period of three years from 2019-20 to 2021-22 at College of Horticulture, Sirsi, Uttar Kannada (Hill Zone of Karnataka) during summer season. Four pest management modules viz., farmers practice, organic farming, natural farming (NF) and recommended package of practices (RPP) were evaluated to manage the pests in an eco-friendly manner. The field experiment was laid out in a randomized block design with five replications comprising of four treatments. The standard protocol was followed for recording observations. Result: Among the different modules tested, farmers practice recorded lowest population of aphids, leaf miner and pod borer and was at par with recommended package of practices. Whereas, Organic farming and natural farming recorded moderate level of pest infestation and quite safe for maintaining the predators like Coccinellids, Chrysoperla carnea and spider population for natural predation. The cost of plant protection measures was also least in these modules which indicates the socially and economically acceptable farming practices which may be adopted for safer French bean production.
