摘　　要：为了了解不同杀菌剂对番茄早疫病菌的混配增效作用,采用菌丝生长速率法测定了异菌脲与代森锰锌混配对番茄早疫病的增效作用。结果表明,异菌脲与代森锰锌以7∶3混配增效系数(SR)为1.71,表现为协同增效作用,而以5∶5、6∶4、4∶6混配的SR值分别为0.88、1.43、0.62,表现为相加作用。以3∶7混配SR值为0.043,表现为拮抗作用。实验结果为异菌脲与代森锰锌合理混用提供了科学依据。Combinative toxicity potential and synergistic effect of mancozeb and iprodione on Alternaria Solani were tested by mycelium lineal growth method in laboratory.The results demonstrated that mancozeb and iprodione mixed at the ratio of 7∶3 had synergistic effect.The synergistic ration（SR） was 1.71.The mixtures at the ratio of 5∶5,6∶4 and 4∶6 had additive effect.The SR value were 0.88,1.43 and 0.62,respectively.The mixture at the ratio of 3∶7 had amensalism effect.It was concluded that the rate of 7∶3 was the best mixing proportion.In this test some useful data for further research was provided.
