Phytophthora is a fungus which affects papaya of all ages at the root zone.
The new leaves at the top start to turn yellow, wilt and fall off. Eventually the plants base at the ground level become soaked and the stem collapses.
Rootrot can also be caused by waterlogging during heavy rainfall.
This fungus can be prevented by spraying a fungicide with carbendazim as the active compound alternated by copper oxychloride e.g chariot and greecop respectively.
Seedlings can also be planted in raised beds or ridges to prevent them from being submerged in water.
Avoid establishing your orchard in a place prone to waterlogging.
