    Efficacy comparison of three pesticides on controlling Rhopalosiphum nymphaeae L.

    • Field efficacy of three pesticides on Rhopalosiphum nymphaeae were tested in this study. The results showed that 10% imidacloprid WP with dosage of 2.0-3.0 g/667 m2 and 5% acetamiprid EC with dosage of 1.5-2.0 g/667 m2 were effective on controlling Rhopalosiphum nymphaeae with quick and persistent effect, significantly higher than treatments of different dosage of 25% pymetrozine WP. These two pesticides could control the occurrence and damage of Rhopalosiphum nymphaeae effectively, and used as prior pesticide for controlling Rhopalosiphum nymphaeae in lotus root production.
