The investigation sigatoka state of an illness before medicine, in the dispenser for the first time of state of an illness initial stage, dispenser in every 7 days once is total to dispenser 2 times.Investigated respectively disease index and calculated preventive effect in 7 days, 14 days after dispenser for the second time.Experimental result is as follows:
Table 6 iprodione tetraconazole is prevented and treated the sigatoka test of pesticide effectiveness
As shown in Table 6, iprodione and tetraconazole are composite remarkable to the sigatoka control efficiency, compare with single dose, have advantages of that preventive effect is high, lasting period length, residual little.In this experimental drug weight range, to banana safety, have no adverse effects, preparation of the present invention has good control efficiency to sigatoka.
