However, experimental findings on GO’s impact on plants have been inconsistent, and our understanding of its long-term effects, impact on yield, and general efficacy remains limited. To address these gaps, we administered GO to rice plants over a period exceeding 80 days and assessed its influence on the final biomass production and grain yield through a two-year experiment. Our results clearly showed that while the positive effects of short-term GO treatments were not detected, the long-term treatment of 20 mg/L GO increased both the final biomass production and grain yield. As no significant interactions between treatment and the year were detected, these outcomes are likely representative of the general effects on rice. Moreover, GO-treated plants exhibited GO coverage on root surfaces, and the presence of certain fertilizer components on the roots significantly increased with the addition of 20 mg/L GO. Therefore, our study suggests that the addition of 20 mg/L GO during the term from transplanting to harvesting promotes the accumulation of fertilizer components around the root, thereby enhancing the final biomass production and grain yield of rice.</p>","PeriodicalId":93846,"journal":{"name":"ACS agricultural science & technology","volume":"4 11","pages":"1230–1240 1230–1240"},"PeriodicalIF":2.3,"publicationDate":"2024-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142671811","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Currently, the most widely practiced system uses <i>Desmodium</i> spp. as intercrop and Brachiaria or Napier grass as border crops to protect maize (<i>Zea mays</i>) against both insect pests and parasitic weeds. Several previous studies have demonstrated the efficacy of the push-pull system, but research on the underlying chemical mechanisms has mostly been limited to laboratory and glasshouse experiments that may not fully reproduce the complexity of the system under natural conditions. To address this limitation, we performed a large-scale study in farmer-operated push-pull maize fields in three east African countries. We compared maize leaf extracts from plants grown on push-pull fields with maize from fields employing conventional agricultural practices to assess the influence of push-pull cultivation on the maize metabolome. We identified two benzoxazinoid glycosides, which are known to have antiherbivore properties and were present in greater relative abundance in push-pull-cultivated maize leaves across three countries. Our data thus suggest that maize cultivated under push-pull has an increased resistance to herbivore attack compared to maize grown under conventional local agricultural practices.</p>","PeriodicalId":93846,"journal":{"name":"ACS agricultural science & technology","volume":"4 10","pages":"1074-1082"},"PeriodicalIF":2.3,"publicationDate":"2024-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11497208/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142514415","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The need for new bioherbicide modes of action has become increasingly urgent in modern agriculture, as most bioherbicides have nonspecific modes of action with no systemic activity. Introducing new modes of action is essential to diversifying weed control strategies, minimizing the risk of resistance development, and ensuring sustainable weed management practices. By fostering innovation in bioherbicide development and promoting the use of novel modes of action, we can safeguard our agricultural systems, reduce the environmental impact of weed management, and maintain the ability to feed a growing global population while preserving the long-term health of our ecosystems. Manuka oil is derived from the leaves and branches of the Manuka tree (<i>Leptospermum scoparium</i>) and contains β-triketones. The β-triketone-rich fraction contains leptospermone and inhibits a key enzyme, <i>p</i>-hydroxyphenylpyruvate dioxygenase (HPPD). This process directly inhibits carotenoid biosynthesis, upstream in the biochemical pathway, which causes damage to the photosynthetic apparatus and leads to bleaching of the leaf tissue, which eventually kills the plant. The β-triketone extract at 2% and 4% had up to 97% control against different weed species in field and greenhouse evaluations. The β-triketone extract was significantly more efficacious vs other bioherbicides such as 20% vinegar and 12.5% <i>D</i>-limonene. Additionally, the β-triketone extract was just as effective as a 2% glyphosate treatment in the greenhouse evaluation against <i>Amaranthus palmeri</i> and <i>Digitaria sanguinalis</i>. The β-triketone extract also reduced <i>Cyperus esculentus</i> growth by 70% at 9 days after treatment. Thus, there is significant evidence that commercializing a water-soluble β-triketone-enriched extract of Manuka oil can be an effective weed control strategy in crop production systems, especially in specialty and organic cropping systems where the need for bioherbicides is critically imperative.</p>","PeriodicalId":93846,"journal":{"name":"ACS agricultural science & technology","volume":"4 9","pages":"907–915 907–915"},"PeriodicalIF":2.3,"publicationDate":"2024-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142234561","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
