In this study, the co-application of tetramycin and chitosan against leaf spot disease in kiwifruit and its effects on the disease resistance, photosynthesis, quality and amino acids of kiwifruit were investigated. The results show that tetramycin exhibited an excellent antifungal activity against L. theobromae and A. tenuissima with EC50 values of 2.37 and 0.16 mg kg\u22121. In the field, the foliar co-application of tetramycin and chitosan could effectively control leaf spot disease with control efficacy of 89.44% by spraying 0.3% tetramycin aqueous solutions (AS) 5000 time liquid + chitosan 100 time liquid, which was significantly (ANOVA, p &lt; 0.01) higher than 79.80% of 0.3% tetramycin AS 5000 time liquid and 56.61% of chitosan 100 time liquid. Simultaneously, the co-application of tetramycin and chitosan was more effective than tetramycin or chitosan alone in enhancing the disease resistance and photosynthesis of kiwifruit leaves, as well as improving the quality and amino acids of kiwifruit fruits. This work highlights that chitosan is a practicable, cost-effective and eco-friendly adjuvant of tetramycin for controlling leaf spot disease of kiwifruit, enhancing resistance and photosynthesis of leaves and improving quality and amino acids of fruits.<\/jats:p>","DOI":"10.3390\/biom12040500","type":"journal-article","created":{"date-parts":[[2022,3,25]],"date-time":"2022-03-25T15:31:21Z","timestamp":1648222281000},"page":"500","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":23,"title":["Co-Application of Tetramycin and Chitosan in Controlling Leaf Spot Disease of Kiwifruit and Enhancing Its Resistance, Photosynthesis, Quality and Amino Acids"],"prefix":"10.3390","volume":"12","author":[{"given":"Cheng","family":"Zhang","sequence":"first","affiliation":[{"name":"Guizhou Food Quality and Safety Technology Service Platform, School of Public Health, Guizhou Medical University, Guiyang 550025, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Haitao","family":"Li","sequence":"additional","affiliation":[{"name":"Department of Agricultural Engineering, Guizhou Vocational College of Agriculture, Qingzhen 551400, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiaomao","family":"Wu","sequence":"additional","affiliation":[{"name":"Research Center for Engineering Technology of Kiwifruit, Institute of Crop Protection, College of Agriculture, Guizhou University, Guiyang 550025, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yue","family":"Su","sequence":"additional","affiliation":[{"name":"Department of Agricultural Engineering, Guizhou Vocational College of Agriculture, Qingzhen 551400, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Youhua","family":"Long","sequence":"additional","affiliation":[{"name":"Research Center for Engineering Technology of Kiwifruit, Institute of Crop Protection, College of Agriculture, Guizhou University, Guiyang 550025, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,3,25]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"31","DOI":"10.1016\/j.scienta.2018.09.026","article-title":"Lacquer Wax Coating Improves the Sensory and Quality Attributes of Kiwifruit during Ambient Storage","volume":"244","author":"Hu","year":"2019","journal-title":"Sci.
