Inhibition Effect Determination of Fungicides on Mycelial Growth of Maize Top Rot Fungus

Determination results of indoor bacteriostasis and toxicity showed that the inhibition effects on mycelial growth of maize top rot fungus were different according to fungicides adopted;maize top rot fungus was sensitive to all fungicides but with different levels of sensitiveness accordingly.10% Cyproconazole,10% Propiconazole,12.5% Myclobutanil and 50% Tuzet were selected as better fungicides to maize top rot fungus,and some useful data on chemical control of the fungus were also provided.
