Go EXTRA easy then. Neem isn't meant to be a systemic. I've NEVER heard of that. I may just be full of shit, but last time I checked neem is meant to form a protective film/barrier.
Is it a good idea to use a spreader/sticker when applying pesticides? Sure! But for their surfactant qualities, not to get the neem INTO the plant's tissues. Weird.
