Hort oil recommendations for serpentine leafminer, septoria and marssonina leaf spot.
I have a client who I've been managing there poplars for years now with simple pruning to keep these bugs/fungas at bay. They would now like to get a bit more aggresive but no chemical pesticided products.
I don't spray or market it at all nor am I looking to start. My knowledge is limited on oils so any info or advice would be great. I'm in canada so the oil would need to be available hear or be able to be shipped.
Thanks
