The invention discloses a composition containing flufenoxadiazam and
tridemorph, and a co-
toxicity test result shows that flufenoxadiazam and
tridemorph are compounded in a certain
mass part ratio range, so that the composition has a synergistic effect on
soybean rust diseases, and particularly, the synergistic effect is remarkable when the
mass part ratio of flufenoxadiazam to
tridemorph is (1: 10)-(20: 1). Compared with a
single component, the activity of the flufenoxadiazam and tridemorph composition is higher than that of the
single component, and the flufenoxadiazam and tridemorph composition can obviously improve the
control effect, reduce the
pesticide consumption, expand the bactericidal spectrum and improve the bactericidal efficiency by compounding the flufenoxadiazam and tridemorph. Meanwhile, the control
workload and the
pesticide cost of agricultural production are also reduced.
