Abstract

Abstract: In order to seek new fungicides and methods for controlling apple ring rot on branches and trunks,the field control effect of self-developed protective biocontrol agent LZ-1was studied.The results showed that the biocontrol agent LZ-1 could effectively inhibit the production of new warts in apple trees with high control effect on the diseased trees,and the highest prevention effect reached 89.93%,which was the same as the chemical methyl thiophanate paint.Treatments of applying biocontrol agent LZ-1 from March to May had good field control effect,which were the key months for field application of pesticides.The effective adhesion period of the biocontrol agent LZ-1 was 60 days on branches，and that was 6 months on trunks.The application of biocontrol agent LZ-1 can reduce the usage of chemical fungicides and achieve the purpose of fungicides reduction．

Key words: Apple ring rot disease, Biocontrol agent LZ-1, Field control effect

摘要： 为了寻求新的防治苹果枝干轮纹病药剂和其使用技术，对自主研发的保护性生物菌剂LZ-1进行了田间防治效果研究。结果表明，生物菌剂LZ-1能有效抑制苹果树树体病瘤数增加，对已发生枝干轮纹病的树体具有较高的防治效果，最高防效可达89.93%，与甲基硫菌灵化学涂剂处于同一水平。在涂药时间方面，3—5月涂抹生物菌剂LZ-1对苹果枝干轮纹病均有较好的田间防效，该时期为田间施药的关键时期。生物菌剂LZ-1在苹果树枝条上的有效附着期达60 d，在主干上的有效附着期可达6个月。施用生物菌剂LZ-1可以减少化学药剂的使用量，达到减药目的。
