Abstract

Abstract Industrial hemp cultivation restarted in Estonia in mid 2000s and the hemp cultivation area has increased very fast in recent years, but it is unknown to what extent hemp productivity can be curbed by widespread crop pests. Thus, the main aim of this study was to evaluate the presence and damage of hemp pests in northern field conditions. A field trial with the hemp cultivars ‘Finola’ (2021) and ‘Estica’ (2022) was established in Central Estonia (58° N, 26° E), and the plants were grown with different fertilizer types (complex fertilizer, ammonium nitrate), fertilization methods (at sowing/top dressing) and nitrogen rates (0–200 kg ha −1 ) and their effect on the European corn borer (ECB, Ostrinia nubilalis ) damage was assessed. The O. nubilalis infestation increased with every observation date throughout the seasons until the harvest. The O. nubilalis damage was overall greater in 2022 than in 2021, and the seed yield reduction reached to 120 kg ha −1 in 2022, indicating progressive increase in O. nubilalis damage. Fertilization rate strongly increased biomass and seed yields, but weakly reduced O. nubilalis infection. Estonia is one of the most important hemp-cultivation areas in Europe, and in northern conditions, the crop was previously considered to be relatively pest-free. The northward movement of crop infection by O. nubilalis implies that future hemp cultivation might need integrated O. nubilalis control practices adapted to site-specific agro-climatic conditions.

欧洲玉米螟(Ostrinia nubilalis)在北欧的广泛发生和对工业大麻(Cannabis sativa)作物的危害

爱沙尼亚于2000年代中期重新开始工业大麻种植，近年来大麻种植面积增长非常快，但目前尚不清楚广泛存在的作物害虫对大麻生产力的影响程度。因此，本研究的主要目的是评价北方大田条件下大麻害虫的存在和危害。在爱沙尼亚中部(58°N, 26°E)建立了大麻品种“Finola”(2021)和“Estica”(2022)的田间试验，并在不同的肥料类型(复合肥料、硝酸铵)、施肥方法(播种/施肥)和施氮量(0-200 kg ha - 1)下种植，并评估了它们对欧洲玉米螟(ECB, Ostrinia nubilalis)危害的影响。在整个季节，直到收获季节，随着每个观测日期的增加，nubilalis侵染增加。与2021年相比，2022年毛茛的总体危害更大，种子产量减少120 kg ha - 1，表明毛茛的危害在逐步增加。施肥量显著提高了毛蚶生物量和种子产量，但较弱地降低了毛蚶侵染率。爱沙尼亚是欧洲最重要的大麻种植区之一，在北部的条件下，这种作物以前被认为是相对无害的。北移的麻属植物感染表明，未来的大麻种植可能需要综合的麻属植物控制措施，以适应特定的农业气候条件。

期刊介绍： Gesunde Pflanzen publiziert praxisbezogene Beiträge zum Pflanzenschutz in Landwirtschaft, Forstwirtschaft, Gartenbau und öffentlichem Grün und seinen Bezügen zum Umwelt- und Verbraucherschutz sowie zu Rechtsfragen. Das Themenspektrum reicht von der Bestimmung der Schadorganismen über Maßnahmen und Verfahren zur Minderung des Befallsrisikos bis hin zur Entwicklung und Anwendung nicht-chemischer und chemischer Bekämpfungsstrategien und -verfahren, aber auch zu Fragen der Auswirkungen des Pflanzenschutzes auf die Umwelt, die Sicherung der Ernährung sowie zu allgemeinen Fragen wie Nutzen und Risiken und zur Entwicklung neuer Technologien. Jedes Heft enthält Originalbeiträge renommierter Wissenschaftler, aktuelle Informationen von Verbänden sowie aus der Industrie, Pressemitteilungen und Personalia. Damit bietet die Zeitschrift vor allem Behörden und Anwendern im Agrarsektor und Verbraucherschutz fundierte Praxisunterstützung auf wissenschaftlichem Niveau.
