Abstract: ObjectiveThe present study was conducted to screen effective bactericides for kiwifruit canker in order to provide references for controling kiwifruit canker. MethodStreaking method was used to isolate and purify pathogenic bacteria of kiwifruit cancer for indoor toxicity test. The indoor toxicity of 16 bactericides was tested using bacteriostatic cir-cle method. Field control tests for kiwifruit canker control were conducted in 2014. Eleven bactericides were used to daub stem disease spots directly at 1:50 dilution and daub stem disease spots engraved longitudinally at 1:50 dilution, and sprayed on leaves at recommended dosage. In 2015, ten bactericides at dilution of 1:10 and other four raw bactericides(such as symplectic) were used to daub canker disease spots of kiwifruit directly. ResultThe indoor toxicity tests showed that median effective concentration(EC50) of 0.15% tetramycin AS, 1.8% Xinjunan acetate AS, 3% zhongshengmycin WP, 20% bis-merthiazol WP and 80% ethylicin EC against bacteria of kiwifruit cancer were 27.3114, 8598.8929, 19486.8899, 20482.1833 and 42113.8064 mg/L respectively. The control effects of 80% bordeaux mixture WP(diluted 50 times) and 20% bismerthiazol WP could reach 70.6% and 64.1% respectively with disease spots daubed directly, but only 47.6%, 8.6% with disease spots daubed after being engraved longitudinally. The control effect of 80% ethylicin EC (diluted 10 times), 0.15% tetramycin AS, 80% bordeaux mixture WP and 20% bismerthiazol WP with the disease spots daubed directly were 79.3%, 60.0%, 50.1% and 41.3% respectively. The control effects of foliage spraying with 80% ethylicin EC (diluted 1000 times), 0.5% lentinan AS(diluted 1000 times), 0.15% tetramycin AS(diluted 600 times), 1.8% Xinjunan acetate AS(diluted 500 times) and 46% copper hydroxide WG (diluted 500 times) were satisfactory and all exceeded 80.0%. ConclusionThe procedure of controling kiwifruit canker by bactericides are as follows: cleaning the garden withbordeaux mixture in winter; during late January-early May, daubing stems with ethylicin, lentinan, tetramycin and bordeaux mixture; since late May, ethylicin, lentinan, tetramycin, xinjunan acetate and copper hydroxide are sprayed to control leaf dis-ease. The bactericides are sprayed every 20 d, each spraying is sparyed for 3-4 times. They can be replaced by bismerthiazol and copper abietate.
