If the plant does not receive treatment, the infection will spread and may die.

If the plant affected adults, as usual, it is that the infection starts with the older leaves.

If infection occurs in a greenhouse, the colonization of tissues, and the expansion thereof, it will be slower.

This white powder evolves to become chlorotic spots developed within the leaves, to invade the upper face thereof.

If the crop is cut open, the process will be much faster. It will be challenging to identify this dust; all that will see stains dead tissue.

Time and conditions

The most common time when you can present the Mildiu lettuce is in spring, although it will not be strange to display it in the early summer months. Remember that Mildew affects other species, like the zucchini, though differently.
