Yes think so too, I have been spraying some heavy systemic stuff but they keep coming back. I am thinking of moving it away from my vegetables as at the moment I am overun but I have set hormone traps, sticky traps and spray neem doesnt seem to work well even for aphids. It is too expensive to spray veg with neem when chemicals are dirt cheaper here but then I wouldn't want to eat the veg!
How about the black spots appearing on the leaves?
The Azatin 0 and Azatin Pro are highly concentrated neem products and they work for me.
When my kava plants get those inconsistent black spots, it is a consequence of the spider mites, thrips damage.
Note, the spots are random. If they were more of a pattern it could be Phoma or a bacteria.
As to the cost of organic pesticides as oppossed to, say Merit systemic, I understand what you mean.
Merit would work like a charm but you should never use it as it is not approved for kava.
