White spots and dead leaves on my mint

Mint    brooklyn, ny

I have white spots and dead leaves on my mint. I've sprayed with organic insecticide and funguscide and no difference.
Any idea what it is? Any help will be greatly appreaciated. I've looked online and can't seem to find an answer.

Hopefully my attachment will work

The white spots could be thrips.

Are the dying leaves at the bottom of the stem? If they are, they could be old leaves.

In my garden, mints need regular water and appreciate afternoon shade in the summer. When I cut my mints regularly (to use a sprig or more), the plant produces new leaves that look fresh and healthy.

michele commented,
thank you for your reply! I'll investigate
almost 6 years ago.

I agree with Tanya in the Garden's assessment that the white spots were probably caused by thrips.
Thrips have been discussed several times on this forum and you should be able to find helpful control tips by entering thrip control into the search box at the top of the website.
Second, I would not be too concerned with the brown spots on the leaves at the bottom of the plant -it looks like senescence or dieback of the old shaded leaves.

I have seen similar damage due to leaf hoppers. I have leaf hoppers in my herb garden at times, and they do go after the aromatic plants.
