Abstract

Sugar cane (Saccharum officinarum L.) is the main ingredient in sugar production. Sugarcane is widely cultivated in warm and tropical areas and is widely used as a sweetener because it contains a lot of fructose and glucose. National sugar production shows a decline, the majority of which is caused by pathogens, especially the fungus Bipolaris sp. capable of producing up to 85% damage per Ha if no control is applied. Biological control using Trichoderma spp. can control this pathogen and is able to promote sugarcane growth. The purpose of this study was to determine the effectiveness of Trichoderma spp. in controlling Bipolaris sp. in vitro. The results showed isolates TD1, TD2, TD3 were able to inhibit Bipolaris sp. antagonistically and volatilely, the antagonist test showed a result of 86% (TD1) while the volatile test of 65% (TD2). Conclusion Trichoderma spp. can inhibit the growth of Bipolaris sp. on an in vitro scale. Keywords: BCA, Bipolaris sp. Trichoderma spp. ABSTRAK Tebu (Saccharum officinarum L.) merupakan bahan utama dalam pembuatan gula. Tebu banyak dibudidayakan didaerah hangat dan tropikal dan banyak digunakan sebagai pemanis dikarenakan mengandung banyak fruktosa dan glukosa. Produksi gula nasional menunjukan adanya penurunan yang mayoritas disebabkan oleh patogen terutama jamur Bipolaris sp. yang mampu menghasilkan kerusakan hingga 85% per Ha jika tidak diberlakukan pengendalian. Pengendalian biologis menggunakan Trichoderma spp. dapat mengendalikan patogen ini dan mampu mendorong pertumbuhan tebu. Tujuan penelitian ini ialah untuk mengetahui efektivitas Trichoderma spp. dalam mengendalikan Bipolaris sp. secara In vitro. Hasil menunjukkan isolat TD1, TD2, TD3 mampu menghambat Bipolaris sp. secara antagonis dan volatile, uji antagonis memperlihatkan TD1 memiliki hasil 86% sementara uji volatile TD2 memiliki hasil 65%. Kesimpulan Trichoderma spp. dapat menghambat pertumbuhan Bipolaris sp. dalam skala In vitro. Kata kunci: APH, Bipolaris sp. Trichoderma spp.

体外评估毛霉菌对甘蔗眼斑病（Bipolaris sp.）

甘蔗（Saccharum officinarum L.）是制糖的主要原料。甘蔗广泛种植于温暖和热带地区，因含有大量果糖和葡萄糖而被广泛用作甜味剂。全国蔗糖产量呈下降趋势，其中大部分是由病原体造成的，特别是双孢蘑菇真菌，如果不采取任何防治措施，每公顷可造成高达 85% 的损失。利用毛霉属真菌进行生物防治可以控制这种病原体，并能促进甘蔗生长。本研究的目的是确定毛霉菌属在体外控制双极孢菌的有效性。结果表明，分离物 TD1、TD2 和 TD3 能够拮抗和挥发地抑制双极孢霉，拮抗试验结果为 86%（TD1），挥发试验结果为 65%（TD2）。结论毛霉菌属可在体外抑制双孢蘑菇的生长。关键词BCA；双极孢霉；毛霉菌 ABSTRACT 甘蔗（Saccharum officinarum L.）是制糖的主要原料。甘蔗广泛种植于温暖和热带地区，因含有大量果糖和葡萄糖而被广泛用作甜味剂。全国蔗糖产量呈下降趋势，其中大部分是由病原体造成的，尤其是双孢蘑菇真菌，如果不采取任何防治措施，每公顷可造成高达 85% 的损失。利用毛霉属真菌进行生物防治可以控制这种病原体，并促进甘蔗生长。本研究的目的是确定毛霉菌属在体外控制双孢蘑菇的有效性。结果表明，分离物 TD1、TD2 和 TD3 能够抑制双极孢菌的拮抗和挥发，拮抗试验表明 TD1 的抑制率为 86%，而 TD2 的挥发试验结果为 65%。结论毛霉菌属可在体外抑制双孢蘑菇的生长。关键词APH 双极孢属毛霉属
