bonsaiTALK Community - View Single Post - something wrong with my juniper tree

I think the horticultural oil is only effective on scale when it is in the crawler or egg stage, which makes it very good as a preventive.

The oils work by suffocation and they can suffocate the plant too. Be careful and make sure it's rated for ornamental evergreens.

Malathion is tough to beat for sheer efficacy. Do be sure and spray in the morning when the wind is lowest and wash up afterwards. I don't know about Juniper scale, but a drop of dishwashing soap may help it stick and penetrate better.

Good luck with Operation: Annihilate!

Regards,

Matt
