Synergism of three spray adjuvants on chlorantraniliprole 5％SC against Phthorimaea absoluta Meyrick
To evaluate the synergism of spray adjuvants to chlorantraniliprole 5％SC against Phthorimaea absoluta Meyrick,control efficacies of chlorantraniliprole suspension solution at dosages of 90％,80％and 70％of the common dosage(recommended dosage)mixed with 0.05％(V/V)adjuvants(organosilicon Silwet 408,mineral oil or aloe essential oil additives)against P.absoluta were evaluated in the field.The results showed that adding three kinds of spray additives could improve the control efficacies of chlorantraniliprole,significantly higher than that without addition of spray additives.Compared with the common dosage,the dosage of insecticide could be reduced by 10％-20％by adding organosilicon Silwet 408,mineral oil or aloe essential oil.In practice,organosilicon Silwet 408,mineral oil or aloe essential oil are recommended to be mixed with chlorantraniliprole 5％SC,which would reduce the application amount of insecticide by 10％-20％.
