Abstract EN
Avermectin-grafted-N,O-carboxymethyl chitosan (NOCC) derivative was obtained by esterification reaction using dicyclohexylcarbodiimide (DCC) as dehydrating agent and 4-methylaminopyridine as catalyst.
The structures of the conjugate were confirmed by FT-IR, 1H NMR, and XRD.
Insecticidal activities against armyworms, carmine spider mites, black bean aphids, and brown plant hoppers were investigated at concentrations ranging from 0.16 to 1000 mg/L.
At the concentration of 1000 mg/L and 500 mg/L, the lethal rate was 100%.
Good insecticidal activity at 4 mg/L was still shown, especially against the black bean aphids and brown plant hoppers.
Moreover, the photostability of the conjugate was evaluated and showed an apparent improvement.
At 300 mins, the residual rate of the conjugate was 11.22%, much higher than 0.2% of the avermectin technical material.
The conjugate we developed showed potential for further study and application in crop protection.
