Entrol contains Propineb, a contact fungicide with broad-spectrum activity against various diseases of rice, chili, grapes, potato, and other vegetables and fruits. Propineb is a polymeric zinc-containing dithiocarbamate. Due to the release of zinc, the application of “Entrol” results in a greening effect on the crop and subsequent improvement in the quality of produce. Entrol interferes at different locations in the metabolism of the fungus; on several points of the respiration chain, in the metabolism of carbohydrates and proteins, and the cell membranes. This multi-site mode of action of Entrol prevents the development of resistance in the fungus.
