Been hand-picking the scales from this plant for a year. The scale was introduced in my plant room on a plant that stupidly I didn't quarantine before I added it to my collection. This is a 10-yr old plant and a favorite. I used the alcohol spray on it when I first found the scale and the plant didn't like that at all. Lost some fronts. Unfortunately the crawlers have moved from the stag to other plants and I have lost some as well. So as much as I hate to do it, I will use Orthene systemically on everything. I need to put an end to this scale. My question is can I use Orthene on the stag? The plan would be next time i soak it to mix the orthene in the water. Appreciate any help.
