Am doing an experiment on a severe pawpaw branch which after I got I placed under the fan for 4days and allowed most leaf stalks fall. After that am to plant in polybags but I don't know if am to treat wound with fungicide before planting it or after and I also do not know the fungicide treatment to use. Please someone should help me out.

If you ask for an organic fungicide, then i would suggest Trichoderma Viride . Treat the part prior to planting. Dip in a solution of trichoderma. In India, it available both in liquid or powder form. Hope this helps. You can also drench the soil after planting.
