Auscultation and diagnosis

We are here in the presence of zucchini plants on which we notice a whitish down. However, the vegetables seem to grow roughly normally. For a doctor, the diagnosis is very simple to carry out. It is indeed a very common disease affecting all cucurbits, the zucchini family. We can also find the same phenomenon on melons. It is powdery mildew and we are facing a case of late attack on developed plants. What can we do against powdery mildew of cucurbits?

Some recommendations

In this case, it is no longer worth intervening. In reality, this disease is harmful to the plant only if it develops very early, that is to say on young shoots. You can opt for a sulfur-based treatment that protects the plant. When powdery mildew attacks later in the season, there is no reason to intervene. You now know how to treat your gray zucchini. There is no reason to be alarmed if the disease does not strike young shoots. You too, ask your questions at The Plant Clinic!
