Thrips and Neem Oil

[Jerry Delaney]

Camille is absolutely right in using a systemic. None of the chemicals used in these post are ovacidal which means that even if you manage to kill most of the adult thrips when spraying, the eggs present will start a new population if only a single spraying is used. Also, thrip eggs take about 2 weeks to hatch in WARM weather which means it may take even longer in cool weather. You being in Singapore, maybe it doesn't make so much difference. Camille's recommendation of using a systemic should allow for enough carryover to get the next generation. Good luck!
