摘要
[目的]筛选能有效防治猕猴桃溃疡病的化学药剂。[方法]通过室内抑菌试验筛选出抑菌效果较好的药剂，并进行毒力测定；通过注干试验探究所筛选药剂对猕猴桃溃疡病的田间防治效果。[结果]从13种药剂中筛选出4种抑菌效果较好的药剂，其中盐酸土霉素抑菌效果最好，EC50为1956μg／mL；田间防治效果最佳的配方是1．000％盐酸土霉素＋0．005％吲哚乙酸＋0．500％ NH3 NO3＋0．500％ KNO3＋0．200％KH2 PO4，猕猴桃溃疡病病斑愈合率达72．3％。[结论]树干钻孔注射1．000％盐酸土霉素防治猕猴桃溃疡病效果较好。
Abstract
Objective] The aim was to screen the chemical bactericides which control PSA (Pseudomonas syringae pv.actinidae) effectively. [Method] Indoor inhibition test was used in chemical bactericides screening, and the toxicity of bactericides screened were tested.The control efficacy in field was tested by injecting trunks trials.[Result] Four bactericides with better inhibitory effect were screened out from 13 chemi-cals, oxytetracycline hydrochloride soluble power was the best, EC50 of which was 1 956 μg/mL.The formula with 1.000% oxytetracycline hydrochloride soluble power +0.005% heteroauxin +0.500% NH3 NO3 +0.500% KNO3 +0.200% KH2 PO4 against PSA was the best, and the spot healing rate against kiwifruit canker was 72.3%.[Conclusion] The kiwifruit canker could be controlled effectively by trunk in-jecting 1.000% Oxytetracycline hydrochloride soluble power.
