3.1 Effects of nano-Se on S. avenae growth.
The inhibitory effects of nano-Se on S. avenae growth are
presented in Table 1. Nano-Se could significantly reduce the number ofS. avenae. Compared to the control, nano-Se (5.0, 10.0, 20.0
mg/L) reduced the aphid numbers by 36.4%, 26.2%, and 11.5%,
respectively (Figure 1). Nano-Se (5mg/L) demonstrated the best showed
better inhibition effects among the three treatments.
