20.500.12556/RUL-164270 Evaluating locally sourced inert dusts as insecticides against the cereal leaf beetle (Oulema melanopus [L.]; Coleoptera: Chrysomelidae) a combined laboratory and field study The Cereal Leaf Beetle (CLB), Oulema melanopus [L.], poses a major threat to wheat (Triticum aestivum L.) production, worsened by insecticide resistance and changing EU pesticide regulations. In 2023, we conducted laboratory and field trials to evaluate five inert dusts (diatomaceous earth, quartz sand, Ailanthus altissima dust, Norway spruce wood ash, and zeolite) against all CLB life stages. We assessed pest abundance, wheat damage index, wheat yield, and grain quality. In the lab, diatomaceous earth was highly effective (96%–100%), followed by Norway spruce wood ash (70.4%–96.7%). Field efficacy was hampered by wet weather, affecting dust applications, although the positive control was effective except against CLB eggs. By the last sampling date, damage indices for diatomaceous earth, A. altissima dust, and wood ash treatments ranged from 3.87 to 4.12, lower than the negative control (4.75 ± 0.02) but higher than the positive control (2.88 ± 0.35). Wheat yield was consistent across all treatments (~5 tons), except for the negative control (4.2 ± 0.86 tons) and A. altissima dust (3.9 ± 0.47 tons). Grain quality showed no significant differences. Our study highlights the potential of various inert dusts against CLB, though wet weather limits their field effectiveness, requiring more applications. Further research is needed to develop practical, sustainable CLB management strategies. cereal leaf beetle inert dusts laboratory and field trial abundance wheat damage index wheat yield alternative control methods varstvo rastlin alternativne metode varstva inertni prahovi pšenica pridelek true false true Angleški jezik Slovenski jezik Članek v reviji 2024-10-18 11:10:19 2024-10-18 11:10:24 2024-10-19 04:25:47 0000-00-00 00:00:00 2024 0 0 23 str. no. 1, art. 2415393 Vol. 10 2024 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 632 2331-1932 10.1080/23311932.2024.2415393 212079107 Evaluating_locally_sourced_inert_dusts_as_insecticides_against_the_cereal_leaf_beetle_(Oulema_melano.pdf Evaluating_locally_sourced_inert_dusts_as_insecticides_against_the_cereal_leaf_beetle_(Oulema_melano.pdf 1 63C410E17BB0FB3EA9E8AD6CAB1BD379 a7685a9495d653027b74756c7de6bd4c993203bc571493ceda822aef022394c2 dc2a734a-8d30-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=194538 https://www.tandfonline.com/doi/epdf/10.1080/23311932.2024.2415393 1 8d99278d-8d30-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=194536 Biotehniška fakulteta 0 0 0
