Zucchini stem rotting

Squash    None Given

I have a mature zucchini plant that started forming a gooey white residue at the base of my stem? What is it and how do I treat it!? I'm worried it will spread to my other surrounding plants.

Hi Melissa, image is not clear please upload few sharper images. The soil looks too wet. How frequently do you water? How is the weather there? Did the pots have proper drainage? Generally warm, wet weather favors fungal disease. The main problems in zucchini are squash vine borer and Plectosporium Blight (images attached).

Pretty sure it was one of those two things. I sprayed a copper spray a client of mine got me, which cleared it up but then the stem higher up completely rotted out so I pulled it 😔 Appreciate your feed back!

You should remove infected material and dispose of it in a plastic bag, or burn it. Also wash the shears and other tools you use. When you water the plant be aware that water spreads around fungal diseases. Try and put the water directly into the soil and avoid spraying the plant. You can also use stick to keep the plant higher up, avoiding to touch the soil so it is less wet.

Squash vine borer is an egg laid by a moth. I have had success covering my squash plants with row cover right from the start of transplanting. Leave it on to prevent moth from descending and laying eggs. When you see the first flowers, then remove row cover for pollination for a morning, then replace it. Do this now and then for pollination and hopefully you'll have less problems. The sun will get through the row cover and keep the plant growing.
