Old
Concept : For Copper fungicides the basic copper is very slow to
solubilize and the action lasts for 90 days. Which means too much copper applied every 14
days ? Well, not if only new leaves are considered on potatoes and vegetables which
require regular doses.
New Concept : The
Sulfur in SUCO oxidizes on the crop leaf and solubilize the copper very quickly. There is
no build up of copper on the older leaves of the plant, so growth not stunted and post
application of SUCO, the bush is healthy as sulfur adds extra nutritional benefits. |
