台灣分離的茄科細菌性斑點病菌58個菌株（包括21個pepper race 1菌株，6個pepper race 2菌株，31個pepper race 3菌株）對硫酸銅及鏈黴素具有不同的感受性，所有的race 1菌株均不抗鏈黴素，但有13個菌株具有抗銅性，所有的race 2菌株（除一個菌株外）不但具有抗銅性也抗鏈黴素，而所有的race 3菌株對硫酸銅及鏈黴素均為感受性。抗銅菌株能在含100~950 µg/ml硫酸銅的培養基上生長，而不抗銅菌株僅能在含100 µg/ml硫酸銅的培養基上生長。抗銅菌株對農藥級銅劑，氫氧化銅及鹼性氯氧化銅，也表現抗性，但其生長可被含銅混合劑，銅鋅錳乃浦及銅合浦所抑制。所有菌株對硫酸錳不具感受性，對硫酸鋅的耐性不高，但菌株間之耐性略有差異，而耐性較高者都存在於race 3的菌株中。在或略高於田間推薦使用的濃度時，快得寧及嘉賜黴素對所有菌株之生長均無抑制效果，而鋅錳乃浦及含四環黴素之藥劑能抑制所有菌株之生長。
Differences in sensitivity to cupric sulfate and streptomycin sulfate were detected
among 58 strains (including 21 strains of pepper race 1, 6 strains of pepper race 2 and 31 strains of pepper race 3) of Xanthomonas campestris pv. vesicaroria isolated from Taiwan. All race 1 strains were sensitive to streptomycin, but 13 strains were resistant to copper. All race 2 strains except one were resistant to copper and streptomycin, while all race 3 strains were sensitive to copper and streptomycin. Copper-resistant strains grew on nutrient agar containing cupric sulfate at 100-950 µg/mI, while sensftive strains grew only at 100 µg/ml. Strains resistant to cupric sulfate also were resistant to copper bactericides, copper hydroxide and copper oxychioride, but were sensitive to copper formulations in combination with mancozeb or cufram Z. All strains were not sensitive to manganese sulfate even at 2000µ g/ml, but showed low tolerance to zinc sulfate. Tolerance to zinc varied slightly among strains, and relatively higher tolerant strains were found only in some strains of race 3. Growth of all strains were not inhibited by copper-8-hydroxy quinolate and kasugamycin, but were inhibited by mancozeb and tetracycline at dosages same as or slightly higher than those recommended for use in the field.
