The use of natural substances for pest control in agriculture is economically viable. It benefits both the human being and the environment due to its low persistence and toxicity. Therefore, the biopesticidal potential of three- plants-derived extracts (clove [], Hing [Hing ()], and Wood Ash []) was evaluated against different ' 'insect's pests on five okra varieties. All the treatments were sprayed at two stages, 1st before flowering and 2nd at the fruit-bearing stage. The results of the 24 h pre-spray revealed that the mean density of , and were significantly lower on a Shehzadi variety. However, among the treatments mean density of the and after 1st and 2nd treatments were substantially more bass with . Moreover, the Mean density of aphids was significantly lower after 72 h and 1-week time intervals. Furthermore, after 1st and 2nd treatments, the was considerably lower with hing on Shehzadi variety. It was found in the present study that the yield of five okra varieties was affected significantly by the application of the three treatments-pesticides. Among the various treatments, the application with recorded a considerably higher crop yield. Therefore, clove, hing and could be effective as alternative pest management methods. Furthermore, biopesticides generally are encouraged since they can proffer the solution of controlling insect pests without any environmental concern.
在农业中使用天然物质进行害虫防治在经济上是可行的。由于其低残留和低毒性，它对人类和环境都有益。因此，评估了三种植物提取物（丁香、小茴香、木灰）对五个秋葵品种上不同害虫的生物杀虫潜力。所有处理均在两个阶段进行喷洒，第一次在开花前，第二次在结果期。喷洒前24小时的结果表明，在Shehzadi品种上，棉蚜、蓟马和白粉虱的平均密度显著较低。然而，在处理中，第一次和第二次处理后棉蚜和蓟马的平均密度与小茴香处理相比要低得多。此外，在72小时和1周时间间隔后，蚜虫的平均密度显著降低。此外，在第一次和第二次处理后，Shehzadi品种上小茴香处理的白粉虱数量显著减少。在本研究中发现，三种处理农药的施用对五个秋葵品种的产量有显著影响。在各种处理中，使用小茴香处理的作物产量显著更高。因此，丁香、小茴香和木灰可作为有效的替代害虫管理方法。此外，生物农药通常受到鼓励，因为它们可以提供控制害虫的解决方案而无需担心任何环境问题。
