The present study aims to evaluate the laboratory and field efficacy of butenolide insecticide, flupyradifurone 200 SL against these key sucking pests, its phytotoxicity, safety to natural enemies as well as pollinators and cost-efficiency in okra. Dose probit mortality assays indicated flupyradifurone to be the most toxic and thiamethoxam least toxic to leafhopper and whitefly. Based on the LC₅₀ values for whitefly and leafhopper, flupyradifurone exhibited 11.07 and 2.98-fold difference, respectively, when compared to thiamethoxam. Laboratory bioassays confirmed that the maximum dose of flupyradifurone (250 g a.i. ha⁻¹) had a high level of toxicity to whitefly adults and leafhopper nymphs. Of the three field rates (150, 200, 250 g a.i. ha⁻¹) of flupyradifurone evaluated under open field conditions, application at 250 g a.i. ha⁻¹ was most effective for the control of whitefly and leafhopper population with a high marketable fruit yield in okra. Flupyradifurone reduced the population of whitefly by 71.80 &amp; 76.68 per cent and leafhopper by 82.19 and 80.21 per cent during first and second season, respectively, as compared to untreated control. Furthermore, it was superior and more economical, giving the highest benefit: cost ratio (2.77) than other test insecticides included for comparison. Flupyradifurone application showed no phytotoxic symptoms on the okra crop. Additionally, it was found to be safer to natural enemies i.e. spiders and rove beetles that are prevalent in the okra ecosystem. The Kaplan–Meier survival analysis showed that flupyradifurone was apparently less toxic to honey bees in short-term and long-term exposure assays. These findings will aid in utilizing the flupyradifurone in insecticide window spray schedules and IPM programs for the management of sucking pests in okra.</p>","PeriodicalId":16838,"journal":{"name":"Journal of Plant Diseases and Protection","volume":"16 1","pages":""},"PeriodicalIF":2.0,"publicationDate":"2024-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140883450","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, it is important to thoroughly study the compatibility and interactions between carriers and biocontrol agents for high-quality biological formulations. The present study aimed to evaluate the effect of four different formulation compositions containing gum katira biogel, vermiculite, and diatomaceous earth on the survival and infectivity of infective juveniles (IJs) of two entomopathogenic nematodes (EPNs) species namely, <i>Steinernema abbasi</i> and <i>Heterorhabditis indica</i> at 25 and 35 °C. The physicochemical analysis of the prepared formulations revealed their slightly acidic nature with pH ranging from 5.65 to 6.10. Rheological studies validated the solid-like behavior of the developed formulations. The highest survival of <i>S. abbasi</i> IJs was observed in the case of gum katira biogel-vermiculite blended composition at both 25 °C (94.2%) and 35 °C (88.4%) after 90 days of storage. Interestingly, gum katira biogel alone sustained maximum survival percentage (63.5%) of <i>H. indica</i> as compared to control (41.5%) after 90 days at 25 °C. The formulation compositions failed to retain alive <i>H. indica</i> IJs at 35 °C even after seven days of storage. Moreover, the gum katira singly or in combination with vermiculite resulted in superior infectivity against <i>Galleria mellonella</i> (4th instar larvae) as compared to the other treatments in case of both the nematode species. The presence of diatomaceous earth in all the compositions irrespective of moisture and EPN species showed a negative impact on the survival and infectivity of IJs after 90 days of storage.
