Eficiency and Safety Evaluation of HaNPV Suspension Formulation Containing Chlorfluazuron

  • Available online: 25 December 2003
  • Abstract:The chlorfluazuron,a chitinase inhibitor acting on pest like a biological agent was selected for enhance Helicoverpa口, era nucleopolyhedrovirus(HaNPV)pesticide.The third instar larvae were infected with the virus mixed witI1 4.2ppm chlofluazuron,the LT50 value Was reduced to 2.44 days, while the larvae infected only with the virus,the LTso was 4.9O days,and only 4.2 ppm chlofluazum did not cause the larva death.TIle H V suspension formulation pesticide.which containing chlorfluazuron,Was produced in the factory.In field test,the 2nd or 4th generation larvae Was controlled by the viral pesticide,7 days after spaying the pesticide,the efi ciency were 85.2%,-,86.3% an d 69.6% —暑2.9% respectively,only slight efec t of the viral pe sticide on the nature enemi es Was observed .
