Control efficiency showed a highly significant positive correlation (P< 0.05) with SS content, SOD activity, and POD activity, and a significant positive correlation (P< 0.05) with PAL activity.
Control efficiency showed a highly significant positive correlation (P< 0.05) with SS content, SOD activity, and POD activity, and a significant positive correlation (P< 0.05) with PAL activity.
At a spraying distance of 1.2 m, CAT activity showed a decreasing trend with increasing angle.
At spraying angles of 0° and 20°, the control efficiency showed an increasing trend as the spraying distance increased, with the best efficiency observed at 1.2 m, which was significantly higher than at 0.6 m and 0.9 m.
