Abstract:
Using Fusarium wilt pathogen of muskmelon as test material，the toxicities of eight agents were tested by the mycelial growth rate and spore germination methods against the pathogen.Calculation of synergistic factors for mycelial growth and spore germination by Wadley method，respectively.And determine the optimal ratio and conduct pot experiment.The results showed that myclobutanil 25% EC and prochloraz 45% ME had the best inhibitory effect on mycelial growth with EC50 0.001 2 mg?L-1 and 0.004 6 mg?L-1，respectively.Azoxystrobin 250 g?L-1 SC and SYP-Z048 25% EC had the best inhibitory effect on spore germination with EC50 0.092 2 mg?L-1 and 3.263 2 mg?L-1，respectively.The four kinds of agents were screened by proportional mixing method.There were 2 mixing ratios obtained which had synergies and addition evaluation on mycelial growth and spore germination of the pathogen.Prochloraz and azoxystrobin were mixed with the mass ratio of 4∶1，SYP-Z048 and azoxystrobin were mixed with the mass ratio of 2∶3.The control effects on melon wilt were 80.42% and 76.57%，respectively，which were significantly higher than single-agent control by pot experiment with 10 mL per plant of 1.0 g?L-1 fungicide solution.These results provide evidences for the use of control agents for Fusarium wilt of muskmelon.
