2. Squash Vine Borers

Vine borers, Melittia cucurbita, are a menace! They lay eggs on the plant’s crown, the place the principle stem meets the soil’s floor.

When the larvae hatch, they tunnel into the stem to feed, wrecking the plant’s vascular system.

As soon as these chubby white caterpillars with brown heads get established, the plant is doomed, with the principle stem weakening till it collapses and the entire plant falls over.

There is no such thing as a disguising the “ick” issue when a illness has “gummy” or “rot” within the description. And each of those fungal ailments are aptly named.

Brought on by the fungus Didymella bryoniae, gummy blight causes damping off in newly sprouted zucchini.

In additional mature crops, the fungus creates lesions on the leaves which are brown or tan and drips a red-brown gum, therefore the identify.

Because the lesions get bigger, they’ll girdle the stems, and this causes complete crops to break down.

Sorry to say, however normally as soon as gummy blight has gotten established, the vines will collapse and have to be eliminated and destroyed.

Black rot can be brought on by D. bryoniae. It sometimes impacts solely the fruit, however because it good points momentum, it could additionally kill the plant, which is able to trigger that telltale slumping over that all of us dread.

These fungi can unfold through the wind, contaminated seeds, or bought seedlings, so be sure to’re buying licensed disease-free seeds from dependable growers.

Any cuts or wounds on the stems of older specimens may enable the fungus to breach the plant. Cucumber beetles, melon aphids, and powdery mildew all encourage gummy blight.
