Nucleopolyhedrosis Virus of Spodoptera Utura: Influence of Environmental Factors on Efficacy And Improvement for Field Application

Nucleopolyhedrosis Virus of Spodoptera Utura: Influence of Environmental Factors on Efficacy And Improvement for Field Application

Chemical pesticides significantly reduce agricultural losses but pose environmental hazards. Their effectiveness are threatened by increasing insect resistance and unwanted destruction of non-target organisms. Nucleopolyhedroviruses (NPVs) are getting wide attention as an alternative and biorati...
