Field Efficacy of Seven Insecticides Against Frankliniella Intonsa(Trybom)in Hemerocallis Citrina Baroni
A field efficacy trial was conducted to investigate the efficacy of seven insecticides for controlling fFrankliniella intonsa(Trybomin)Hemerocallis citrina Baroni.The results indicated that all insecticides demonstrated notable control effects,with efficacies peaking initially and then gradually declining over time.The 30%spinosad·thiamethoxam suspension concentrate(SC)exhibited the best quick-acting and long-lasting performance,achieving over 90%control efficacy within 1~3 days post-application and maintaining efficacy above 70%efficacy seven days after treatment.Based on the findings,the combined formulation of spinosad and thiamethoxam was recommended as the preferred option for controlling Frankliniella intonsa(Trybom)in Hemerocallis citrina Baroni.To prevent the development of pesticide resistance in Frankliniella intonsa(Trybom),the study also recommended the use of other pesticides,including dinotefuran,cyantraniliprole,bromofluramide,tolfenpyrad,chlorfenapyr·tolfenpyrad,and Metarhizium anisopliae,to ensure effective control of Frankliniella intonsa(Trybom)in Hemerocallis citrina Baroni and promoting the continuous healthy growth and stable yields of Hemerocallis citrina Baroni.
