Abstract

AbstractThe impact of hazard by chemical fungicides has necessitated the development of safe and eco-friendly bio-fungicides. Trichoderma asperellum is one of the potent biocontrol agents and for its cost-effectiveness large scale production on several agricultural and industrial wastes has been tested so far. Forest fire due to highly inflammable pine needles and invasion of weeds are considered as a major cause of biodiversity loss in forests of NW Himalaya. Therefore, in the present work, the potential of forest wastes like needles of five conifer species and foliage of three noxious weeds along with some commonly used substrates were evaluated for the mass production of T. asperellum. Amongst all the screened substrates, the highest spore count was recorded on Pinus roxburghii needle powder supplemented with yeast extract and potato dextrose broth. Therefore, authors recommend the use of P. roxburghii needles for the mass multiplication of Trichoderma species as a replacement for useful agro-wastes.Keywords: Conifer needleweedsTrichodermamass multiplicationsubstratesspore load per gram (SLPG) Disclosure statementNo potential conflict of interest was reported by the author(s).Additional informationFundingThe authors are thankful to National Authority Compensatory Afforestation Fund Management and Planning Authority (CAMPA), New Delhi for financial support “OM 13-30/2019/NA, dated 06/12/2019”.

曲霉木霉在针叶和杂草叶上的大量繁殖

摘要化学杀菌剂对危害的影响，要求开发安全环保的生物杀菌剂。曲霉是一种有效的生物防治剂，由于其成本效益，迄今已在几种农业和工业废物上进行了大规模生产试验。高度易燃的松针引起的森林火灾和杂草的入侵被认为是喜马拉雅西北部森林生物多样性丧失的主要原因。因此，本研究对5种针叶树的针叶和3种有毒杂草的叶片等森林废弃物以及一些常用的基质进行了大规模生产曲霉的潜力评价。在所筛选的基质中，以添加酵母膏和马铃薯葡萄糖肉汤的刺梨针粉为培养基，孢子数最高。因此，作者建议使用刺木针剂作为有用农业废弃物的替代品，用于木霉物种的大量繁殖。关键词:针叶树针叶草生物量繁殖底物每克孢子负荷(SLPG)披露声明作者未报告潜在利益冲突。作者感谢新德里国家管理局补偿性造林基金管理和规划局(CAMPA)提供的财政支持“OM 13-30/2019/NA，日期为06/12/2019”。

期刊介绍： Archives of Phytopathology and Plant Protection publishes original papers and reviews covering all scientific aspects of modern plant protection. Subjects include phytopathological virology, bacteriology, mycology, herbal studies and applied nematology and entomology as well as strategies and tactics of protecting crop plants and stocks of crop products against diseases. The journal provides a permanent forum for discussion of questions relating to the influence of plant protection measures on soil, water and air quality and on the fauna and flora, as well as to their interdependence in ecosystems of cultivated and neighbouring areas.
