Originally from southern Mexico particularly Chiapas and Veracruz, Central America, and northern South America,5 the papaya is now cultivated in most tropical countries. Papaya' title='Papaya' />In cultivation, it grows rapidly, fruiting within three years. It is, however, highly frost sensitive, limiting its production to tropical climates. Temperatures below 2 C 2. F are greatly harmful if not fatal. In Florida, California, and Texas, growth is generally limited to southern parts of the states. It prefers sandy, well drained soil, as standing water will kill the plant within 2.

In some of the older spots, the fungus may produce pink spores. The fruit ends up being soft and having an off flavor because the fungus grows into the fruit. The fungus powdery mildew occurs as a superficial white presence on the surface of the leaf in which it is easily recognized.
