Durban Poison (Green Smoke Room Fast)

The rust infection is very aggressive. On Monday the rust infection had spread to the front-left plant and had spread up the front-right plant, which is the closest to the entrance. I immediately purchased and applied a Mancozeb-based fungicide to the foliage. Mancozeb is a non-systemic fungicide that is non-toxic to wildlife and safe for humans. The drawbacks are that it is only effective in combatting infection on the leaf surface, and cannot eradicate the infection completely from within the plant. It has proving useful in controlling the spread and largely preventing infection of the back two plants. However, the infection is likely to remain in the tank until I am able to sterilise it. As the plants grow, I will remove as much affected foliage as I can to decrease the concentration of spores. I have already removed the leaves from the first node on the front two plants (not shown on the photographs). The front plants are noticeably stunted from the infection and defoliation. They have compensated by stretching. I will control the height with LST after they have been topped.
