This contrasts full-season soybean production where soybean are planted earlier in April and May. Usually, double-cropped soybean does not yield as high as full-season soybean due to a shorter period of vegetative growth. Hence, photosynthetic tissue loss by defoliating insects might have a great negative impact on yield loss in double-cropped relative to full-season soybean, but this has not been extensively explored. We hypothesized that defoliation during R5 (seed filling) would cause more yield loss in doubled-cropped compared to full-season soybean. To explore this, we planted soybean either in May or July, simulating full-season and double-cropped cropping systems, and manually defoliated plants by removing leaflets at R5. We compared 0, 16.7, 33.3, 66.6 and 100 % defoliation levels in a factorial design. We evaluated yield, yield components (number of pods per plant, number of seeds per pod, and weight of 200 seeds) and canopy coverage. Full-season soybean had a higher overall yield compared to double-cropped soybean. Across both cropping systems, yield decreased as defoliation levels increased. Across defoliation levels, some yield components were reduced, but only at high defoliation levels (100 % defoliation). Across cropping systems, seeds were heavier in full-season compared to double-cropped soybean. Overall, the impacts of defoliation did not change between these two cropping systems. These findings need to be supported by further research to refine thresholds for defoliating insects in southeastern US soybean.</div></div>","PeriodicalId":10785,"journal":{"name":"Crop Protection","volume":"197 ","pages":"Article 107347"},"PeriodicalIF":2.5,"publicationDate":"2025-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144723728","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 drench application of cyclaniliprole has proven effective in reducing the emergence of adult <em>S. frontalis</em> from infested containers; however, the effects of winter application and lower rates of cyclaniliprole are poorly understood. Thus, the objectives of this study were to determine the effects of 1) single and repeated drench application of cyclaniliprole in the winter and 2) reduced label rates of cyclaniliprole on the adult <em>S. frontalis</em> emergence and feeding damage in the containerized panicled hydrangea. In the winter of 2023 and 2024, cyclaniliprole was drenched in February, March, and April as a single and repeated application. Three repeated drench applications of cyclaniliprole reduced the emergence of adult <em>S. frontalis</em> by 94–100 % and feeding damage compared to nontreated plants. The emerging adults and feeding damage during February, March, or April were similar to repeated applications, suggesting that a single drench of cyclaniliprole during the winter can effectively reduce adult emergence and is comparable to repeated applications. In addition, results showed that 0.25 × and 0.5 × rates of maximum label rate of cyclaniliprole applied as a drench did not consistently reduce adult <em>S. frontalis</em> emergence and feeding damage on panicled hydrangea as compared to the maximum label rate of cyclaniliprole.

The entire detection process was completed in 65 min, including crude nematode DNA extraction (10 min), recombinase polymerase amplification (RPA) (30 min), and CRISPR/Cas12a-based detection (25 min). Compared with PCR and qPCR assays, the proposed diagnostic method demonstrated high sensitivity, with detection as low as 4 copies/μL per reaction, and exhibited high specificity for <em>P</em>. <em>coffeae</em> without cross-reactivity with other common plant-parasitic nematodes. The detection results obtained using RPA-CRISPR/Cas12a were highly consistent with those of conventional PCR assays conducted on 18 seed yams, indicating the method's high applicability and accuracy for field detection.

Specifically, we examined changes in planting anomalies (i.e., the amount planted relative to the long-term average) relative to two variables that could explain wild pig pressure: the proportion of a county with wild pigs and a trend in the intensity of management, while accounting for other variables that could influence decisions to plant. We found that greater overlap with wild pig range was associated with larger planting anomalies for cotton. However, removal of wild pigs did not influence planting anomalies for any crop. We also found that planting anomalies were influenced by return on investment, climate, and the amount of Conservation Reserve Program lands. For some crops, these other factors were more influential than pressures from wild pigs. Our results indicate that producers are planting more cotton in areas with greater presence of wild pigs, and current management efforts to reduce populations of wild pigs are not altering those decisions.
