Can anyone identify what's destroying my herbs?

Seem to have either thrips or fungus gnats or something else attacking my mint and oregano plants, but I'm not exactly sure what it is. Any help would be much appreciated!
a) My mint plant seems to have some white stuff on the stems.
b) Another close up of my mint, as you can see there's black dots under the leaf and brown bits, maybe the plant has been chewed?
c) Similar thing happening with my oregano.
d) Another close up of my oregano

I live in London, the weather has been sunny and humid (around 21 - 30 degrees) for about 2 months now, up until September, where things have started to cool down a bit.
I keep my herbs in a small greenhouse in my garden:
As for pics of the whole plant, I sadly threw away a lot of my mint yesterday to try and curb the infestation/disease, but here's a pic of the cuttings. It's hard to see the damage but try and zoom in.
Here's the oregano:
Hope that helps, and thank you 😊Related Discussions
Can anyone identify what is going on with my peach trees?
Comments (7)Hi Lisa, I actually recognized your name from a few years ago and found your old posts dealing with these trees: Peach tree issue and Peach Tree troubles I'm sorry you've been fighting this for so long and are still struggling with these trees. Scott and Hman have give you some sound advice. From your past threads, I think it's conclusive your trees have had issues with peach leaf curl. You mention last summer you still had to pull off "curled" leaves, so it sounds like you're still having issues with leaf curl. Because of this, I'm going to recommend a stronger product to you for leaf curl. It is available at garden centers and has the active ingredient "chlorothalonil". It is sold under names like Fungonil or Danconil. Like any leaf curl product, it must be applied after leaf drop in the fall, and/or before buds swell for it to work, which may mean its too late for you this spring. I applied my leaf curl sprays on a warm Feb. day this year. Oozing peaches are a result of some damage to the peach. Think of the ooze as the peach bleeding. It is the peach's way of protecting itself from injury. The blood/ooze bleeds out of the wound and hardens to form a sort of protective "scab". Anything can cause injury to the peach/fruitlet and cause bleeding. Most commonly it's a small worm. Sometimes the worm will crawl out of the peach, so that you don't see it when you open the peach. Some beetle type insects will also feed on the fruit. They have piercing mouthparts that suck the juice out of the peach. The site of feeding is an injury and can produce oozing. Any mechanical injury that breaks the skin of a peach (even a very minute break) can cause oozing. However, since it appears to affect most of the peaches in your case and you describe them as unattractive, it sounds a lot like insect damage which will require insecticide sprays to prevent this problem. I would also agree with Scott that you have some canker issues going on in the photos. The best antidote against canker is to promote healthy vigorous trees. Good drainage, a large weed free mulch ring around the trees, eliminating symptoms of leaf curl, and good pruning to promote new growth and open up the tree to sunlight are important. For peach trees grown outside in the soil, a good measure of the health of the tree is how much annual growth the tree puts on. Weak trees will have little new growth (red wood) and will have a significant amount of dead shoots. Healthy vigorous trees will easily have some shoots with 3' of growth or more (if left unpruned). Observe the growth from last season to assess the general vigor of your tree. Canker can continue to spread and eventually kill the tree, but good cultural practices will go a long way to halt or heal the damage. Of the ones mentioned, good drainage and a mulch ring are the most critical in my area. I'm not surprised you were able to harvest peaches effortlessly your first year. Insects, diseases and other pests sometimes take a few years to "show up" and when they do they don't want to leave the party....See Morecan anyone identify what is nibbling my leaves?
Comments (1)Andrea, those look like the sharp irregular notches left by feeding adult weevils. Evergreens like rhododendron and azalea are often their targets but I've found them on siberian iris and mayapple too. Small, maybe 1/4" - 1/2", black, brown or tan in color. Go out after dark with a flashlight and see if you can find any of these on the leaves: Here is a link that might be useful:...See MoreCan anyone identify what varmit bit my mater
Comments (5)Thanks all The tomato was about 5ft high Uncle T, the others about 4ft. As far as them Cherry bombs I will post a new photo thread on hotpepper. I just put themsome in new in fabric pots I just got. @tomatomike thanks, for the response, I just hope to get this thing :). I thought it could be a catipillar. only one way to see. I am setting my GoPro camera out to film for a few hours. I really want to go after this varmit "Bill Murry style from cadyshack". Last year we did have a squirrel problem and many years before as well. But this year a huge red bird "Not Cardinal" but has been sitting on the fence and lives in the tree next door, it has a redish orange belly. Out of my own stupidity I just sprayed Wd-40 on the fence before I read the replys, someone at the garden shop said it prevents birds if that is the culprit but who knows. I will take everyones advice and thanks again both for replying. I posted a video of my squirrel problem last year. with my GoPro camera. The squirrel kept coming into my back yard and was trying to see what he was doing. Edit on: Tomatoe in trash thanks again both :) Just hope it is not an inlaw as Uncle T said Here is a link that might be useful: my squirrel problem last year This post was edited by thebutcher on Tue, Jul 9, 13 at 19:02...See MoreCan anyone identify this pest issue (black spots under leaves)?
