Perceptions were assessed using a five-point Likert scale (Cronbach's α = 0.76), complemented by data on pesticide practices and Bt cotton adoption potential, collected in 2022. Results revealed substantial perception-practice gaps: while 96% recognized health risks from excessive pesticide use, only 77% used personal protective equipment. Critical knowledge deficits were evident, with only 68.4% understanding stage-specific application requirements and 53.4% aware that insect-resistant varieties reduce pesticide costs. Most farmers (55%) relied on peer consultation rather than extension services for pesticide application decisions. Concerning disposal practices prevailed, with 39.7% burying containers and 30% leaving them in fields. Despite chemical reliance, farmers demonstrated high adoption of nature-based practices, particularly pheromone traps (89.5%) and removal of affected parts (84.6%). Regarding Bt cotton, 86% expressed willingness to adopt at current prices, declining to 52.5% at 50% premium, revealing severe price sensitivity. Findings highlight critical gaps between risk awareness and safety practices. Realizing Bt cotton adoption potential requires intensive extension programming addressing knowledge deficits, improved waste management infrastructure, and financial support for resource-constrained smallholder farmers.</div></div>","PeriodicalId":10785,"journal":{"name":"Crop Protection","volume":"203 ","pages":"Article 107548"},"PeriodicalIF":2.5,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146072094","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}

The EO was toxic to second-instar caterpillars (LD50 = 13.36 μg of EO/caterpillar). Methyl chavicol was identified as the major compound (86.14 %) in EO and exhibited toxicity to S. frugiperda. The EO reduced the emergence of T. remus in the F2 and F3 generations when exposed during the egg and pupal stages within the natural host and was classified as harmless to slightly harmful according to the IOBC scale, without affecting parasitism rates. The sex ratio was reduced. The O. basilicum EO caused 100 % mortality in adult female T. remus. In conclusion, O. basilicum EO is toxic to S. frugiperda and induces transgenerational effects on T. remus emergence during the egg and pupal stages, while exhibiting high toxicity to adult females. These findings indicate that O. basilicum EO is compatible with T. remus during its immature stages and underscore the need for application strategies that prevent exposure of adult parasitoids in IPM programs.</div></div>","PeriodicalId":10785,"journal":{"name":"Crop Protection","volume":"203 ","pages":"Article 107551"},"PeriodicalIF":2.5,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146072092","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}

This study aimed to identify alfalfa cultivars with natural resistance to A. craccivora and to elucidate the underlying resistance mechanisms by testing the hypothesis that specific plant nutrients and secondary metabolites are key drivers of aphid resistance. To evaluate the suitability of alfalfa cultivars for cultivation in southern China in terms of their resistance to A. craccivora, life tables were constructed for aphids reared on different cultivars. In addition, the nutrient and secondary metabolite contents of the alfalfa were quantified, and their correlations with aphid life-history parameters were analyzed. The results showed that alfalfa cultivars significantly influenced the life history of A. craccivora, with the Algonquin cultivar exhibiting the strongest negative effects. Integrating life table parameters with chemical profiling revealed that tannins and total phenols are key biomarkers for resistance. Elevated levels of these compounds were strongly associated with a cascade of detrimental effects on A. craccivora, including reduced adult longevity, shortened oviposition periods, and a decreased net reproductive rate, ultimately leading to suppressed population growth. Algonquin was identified as a cultivar with strong natural resistance to A. craccivora, while also elucidating the physiological and biochemical characteristics underlying resistance among alfalfa cultivars. These findings provide a theoretical basis for breeding insect-resistant alfalfa and for developing integrated pest management (IPM) strategies.</div></div>","PeriodicalId":10785,"journal":{"name":"Crop Protection","volume":"202 ","pages":"Article 107497"},"PeriodicalIF":2.5,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145598554","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}

During August–September 2023, an outbreak of brown leaf spot was observed on Chinese cabbage at Xiangyang Farm, Xiangfang District, Harbin, China. Initial symptoms on infected plants included round to irregular brown leaf spots with whorled centers, which gradually expanded and eventually led to complete leaf necrosis. The causal agents were identified through isolation, morphological characterization, and phylogenetic analysis based on the internal transcribed spacer (ITS), elongation factor 1-α (EF1-α) gene, and the second largest subunit of RNA polymerase II (RPB2). The pathogens were identified as Fusarium equiseti (F. equiseti) and Fusarium oxysporum (F. oxysporum). Koch's postulates were fulfilled by inoculating pure cultures onto Chinese cabbage, where symptoms induced by F. equiseti were consistent with those observed in the field. Host range assays demonstrated that F. equiseti can infect plants from Poaceae, Fabaceae, Solanaceae, Brassicaceae, Cucurbitaceae and Amaranthaceae. Biological characterization showed that F. equiseti (F.eq 1) exhibited optimal growth at 25 °C and pH 7 under any photoperiod, using a nitrogen-free medium supplemented with carbon sources including soluble starch, sodium carboxymethyl cellulose (CMC-Na), or xylose.
