Problem in papaya seedling

Hello Sir
I suppose it is Damping-off disease which attacks seedlings.(Pythium aphanidermatum, P. ultimum, Phytophthora palmivora and Rhizoctonia sp.)
The fungi live in the soil.
The disease is favored by high temperature and wet weather, wet soil, poor drainage, deep sowing, thick sowing (crowded), poor soil aeration, high nitrogen in the soil and sunshine shortage.
Infected seedlings will wilt, fall and then die.
Control:
Use virgin soil or sterlize the soil with steam at 180°F (82.3°C) for 30 minutes or fumigate with methyl bromide (see manufactures recommendations)
Protect with plastic film from rain water.
Drench the slution of 35% Etridiazole (Terrazole)
Well-drained soil should be used for planting and the crop should not be excessively irrigated.
Before sowing, the seeds should be treated with fungal culture of Trichoderma viride (3-4 g/kg of seed)
or Captan (3 g/kg of seed) to protect the newly emerging seedlings.
