The effect of azadirachtin-based biopesticide to the prevention of coconut black headed caterpillar in Ben Tre province
Published: July 30, 2026
Abstract
Considering the emerging threats of pests to the coconut cultivation in Ben Tre province (Vietnam), this study was conducted to evaluate the activity of azadirachtin-based biopesticide against the coconut black-headed caterpillar (Opisina arenosella). Accordingly, the sample with 2% of azadirachtin provided a good insecticidal activity in comparison with Reasgant 3.6EC - a commercial pesticide. Although the studied samples exhibited lower bioactivity than the controls (85% and 92% respectively after 7 days), no adverse effect was observed on the growth of coconut trees during the field experiments.
