Hello,

I have a Harlequin rose which produces an abundance of rose hips. I am
careful not to spray any pesticide on the plant as I harvest the hips. So
far so good. If I do spray anything - I use a combo of both Eucalytus Oil
and Soap.

Lately its been infested with thrips - causing discoloration in the flowers
and damage to the leaves. I've sprayed Rogor a systemic pesticide on the
plant - and cut off all the flowers/hips and thrown them away. I probably
have to do a repeat spraying in 10 days times to kill off more of the
thrips. Then destroy all spent flowers - next month February.

Would it be safe to assume that the pesticide would have run its course by
the end of February? And by late March one could safely harvest the hips for
human consumption?

Its currently Summer now over here. Autumn will be in April.

Cheers,

YMC
