Abstract

Abstract:

To clarify the recovery of susceptibility to borer pest and to investigate the current effect of monosultap and its formulations in controlling borer pest damage, a strategic UAV prevention trial (field early damage phase UAV prevention once, followed by a second UAV prevention 10 days later) was conducted using monosultap and its mixtures with quinalphos and diazinon at the early damage stage of early japonica rice borer pest infestation. The results showed that the 100 g 80% monosultap SP treatment had a corrected seedling protection effect of 87.64% on 0 d (the day of the strategic second application), which increased to 90.57% on 10 d and was maintained at 80.45% on 25 d, better than the effect of 20% monosultap AS 400 mL + 25% quinalphos EC 200 mL treatment,80% monosultap SP 100 g + 25% quinalphos EC 200 mL, 80% monosultap SP 100 g + 50% diazinon 150 mL, which were organophosphate mixtures. The effect was also better than the control treatment of 25% spinetoram WG 15 g. It can be seen that the single formulation of 80% monosultap SP 100 g is more sensitive to borer pest, overall superior to the equivalent dosage of AS formulations, and better than its mixtures with auinalphos and diazinon, showing good effects on controlling damage, protecting seedlings, and preserving panicles.

Key words: rice borer pest, monosultap, susceptibility, control effect
