This study evaluated the effects of cover crop termination timing (90 and 120 days after planting, DAP) and cover crop incorporation, along with the application of an organic bioherbicide (Suppress EC), on PPN and weed suppression during the 2021 and 2022 winter seasons. The experiment utilized seven treatments of oilseed radish, oat, rye, mustard, a rye-oat mixture, and two fallows (with and without weeds), replicated five times per season for each termination timing and terminated at 90 and 120 DAP and incorporated into the soil. Results showed that termination timing significantly influenced PPN populations, with rye and oat reducing <em>Meloidogyne incognita</em> densities when terminated at 90 DAP, while mustard and radish increased nematode populations at 120 DAP. Incorporation of cover crops did not consistently enhance nematode suppression, especially in low-biomass scenarios. Weed suppression was more effective with later termination (120 DAP), particularly for rye and oat, which reduced weed biomass through shading and allelopathic effects. The combination of cover crops with bioherbicide further improved weed control, with significant reductions in corn spurry (<em>Spergula arvensis</em>) and cutleaf geranium (<em>Geranium dissectum</em>) compared to cover crops alone. However, the bioherbicide was less effective in suppressing weeds in mustard and radish plots. These findings highlight the importance of selecting appropriate cover crops and optimizing termination timing to manage PPNs and weeds. Integrating bioherbicides with cover crops offers a promising strategy for organic vegetable production, enhancing weed suppression and contributing to sustainable agroecosystems.</div></div>","PeriodicalId":10785,"journal":{"name":"Crop Protection","volume":"193 ","pages":"Article 107205"},"PeriodicalIF":2.5,"publicationDate":"2025-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143666550","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, this study aimed to gather information of insecticide resistance development, cross-resistance pattern, and inheritance mode of resistance to clothianidin and triazophos in laboratory selected strains of <em>O</em>. <em>hyalinipennis</em>. The results showed that after 9 generations, resistant strains developed high levels of resistance to clothianidin (640.97-fold for Clothi-RS3, 1204.06-fold for Clothi-RS2, and 2472.52-fold for Clothi-RS1) and triazophos (236.38-fold for Triaz-RS3, 299.53-fold for Triaz-RS2, and 714.15-fold for Triaz-RS1) compared to the susceptible strains.

Similarly, extremely high cross-resistance to clothianidin (255.90-fold), profenofos (451.33-fold) and indoxacarb (954.79-fold) in the Triaz-RS1 strain was observed. Overlapping 95 % confidence limits of LC_50s of all reciprocal crosses and degree of dominance values revealed an autosomal and incompletely dominant resistance to clothianidin and triazophos.

In conclusion, clothianidin and triazophos resistance was inherited as autosomal, incompletely dominant, and polygenic in the Cloth-RS and Triaz-RS. The high level of cross-resistance to clothianidin, triazophos, profenofos, and indoxacarb indicates that these pesticides are ineffective in controlling the target pest.

Laboratory choice and no-choice experiments were conducted to assess oviposition preferences, potential deterrent effects of Bordeaux mixture, and its toxicity to eggs. In the choice experiment, <em>L. botrana</em> females showed significant preference for untreated grapes under both climatic conditions. However, in the no-choice experiment, Bordeaux mixture neither significantly deterred oviposition nor affected egg hatching rate in either scenario. While Bordeaux mixture had minimal influence on oviposition behavior, future climatic conditions significantly reduced female longevity and fecundity. This reduction in reproductive output may suggest lower pest pressure, but accelerated generation turnover and increased voltinism under warmer conditions could amplify pest pressure in the long term. This study provides insights on the collateral effects of Bordeaux mixture on <em>L. botrana</em> under a future climatic scenario and emphasizes the need for further research on its potential impacts on other key life history traits (e.g., development, reproduction).
