The Field Efficacy Test of Six Fungicides to Control Peanut Root Rot Disease

Using the peanut variety Tang 8252 as the mateiral,the field efficacy test of six fungicides(25% Carbendazim WP,70% Thiophanate-Methyl WP,10% Metalaxyl·48% Mancozeb WP,30% Hymexazol AS,400 g/L Flusilazole EC,25 g/L Fludioxonil FS)to control peanut root rot disease was carried out by fungicide dressing method.The results showed that the emergence rate of peanut seeds under 25% Carbendazim WP treatment was dcreased after dressing,and the emergence rate under others were increased in different degrees.The incidence of peanut root rot disease under 25 g/L Fludioxonil FS and 400 g/L Flusilazole EC treatments were lower,which respectively were 3.50% and 4.41%,and the control effects were as high as 82.06% and 77.40%.The yields of all the fungicides treatments were increased compared with CK,and the increase rate of yield under 25 g/L Fludioxonil FS,400 g/L Flusilazole EC and 70% Thiophanate-Methyl WP treatments were all more than 10%.
