Analysis the similarities and differences between synergic ratio and co-toxicity coefficient and study the standard evaluating the combined action of fungicide mixture
To put forward a unified evaluation standard for synergism of fungicides,the combined action of the binary combinations of tricyclazole and sulfur by 3∶ 1,2∶ 1,1∶ 1,1∶ 2 and 1∶ 3 was tested by dipping 3-4 leaf stage of rice seedlings and inoculating with rice blast fungus spore suspension.The results evaluated with synergic ratio showed the combinations mixed by 3∶ 1,2∶ 1,1∶ 1 and 1∶ 2 were additive action and by 1∶ 3 was antagonism,and the results evaluated with co-toxicity coefficient indicated the combin...

efficients,EC50only responded 50%inhibition rate on rice blast fungus and did not take into account the inhibition raterange,but co-toxicity factor did it.The results indicated that the Synergism of fungicide mixture was judged more correctlythrough using
