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
