Zucchini leaves curling downward

[Hazy]

Hi,

My zucchini plant leaves have curled downward with the older leaves almost touching the ground. It is not wilting because the leaves are all in good shape but just curled downwards. It happened in few plants before too but they recovered after a while. Below is the scheme of things I'm following to grow my zucchini plants.

Water 2-3 inches weekly since it's around 40 Celsius during day time.
Use hydrogen peroxide weekly for disinfection
Use NPK 20 20 20 weekly to feed my plants
Using cow manure dressing in grow beds
Weekly fungicide programme using systemic and protectant fungicide mixes.

I have also attached photos for your reference.

Regards,
Hazy

Hi Chuck,

There is you answer. All plants wilt in the heat of the afternoon, it's normal. If they are wilted at 7AM something is wrong, and in that kind of heat, they are probably thirsty

Any sign of squash vine borer? I can't tell from the pictures, but that's what my plants look like when they start getting attacked.

I am going to say it is just afternoon wilting also. The ground around the plants seems pretty baked. Depends on your situation, but you could try getting them a little more shaded.

This could be a sign of a viral infection. I have grown zucchinis before and the leaves are attacked by a host of insects feeding on their soft leaves. In the process, they transmit plant viruses through their biting mouthparts hence the leaf curl. Controlling there insects holds the key to controlling the transmitted virus. A very effective natural method of control is by placing some garden toads in the zucchini farm. They are extremely voracious feeders and will effortlessly decimate these pests.
