Abstract
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.
