Hop Pests ID thread: Pics, descriptions and solutions

That is indeed a horn worm. They hide in the inner parts of the plant in the day but come out during sunrise and sunset to chomp your prized plants.

Thanks for the confirmation. I'm just hoping that it contents itself with the tomato plant. Fortunately hops don't really have interiors so with any luck it won't be able to hide very well on it.

That horn worm looks disgusting!

If you ever see that thing with little white eggs on it, do not remove it from your plants. These are wasp eggs and they will hatch and eat the hornworm and discourage others from coming back onto your plants. If you remove it they will eventually come back. It gets pretty nasty (and pretty cool) when the wasp larva start eating it.

Mites Suck! Literally. Here's a couple pichers of what I found today whilst out watering the girls growing up the chimney. FIRST: Healthy leaves on top and damaged on bottom. SECOND: Closer look at minor damage compared to healthy leaves. THIRD: Usually starts off with what they (the bug peoples) call a 'bronzing' and FOURTH: Eventually progresses to a bleached appearance. Nothin' that a few Smuttynose IPA's can't take care of!!

If you dont see those eggs, kill it immediately. They will decimate half a tomato plant in a day. Also, Ive never seen just one. Check those 'maters everyday for a week for its bros.

A 50/50 rubbing alcohol and water mixture works great on mites. It kills them on contact and won't hurt your plants. Just spray em down for a few days in a row, this worked for me like a month ago. Since, I've been spraying weekly with organicide and I haven't been having any more pest problems. Make sure to check the bottom leaves since they start low and spread up. They also infest quickly so kill them now before they ruin your precious harvest.... Good luck!!!

Thanks man, but I'll stick to the IPA. It's been about 1000F for the last month or so and I don't care what happens. My day job dictates that I work out in the 1000F weather so when I get home I like to be comfortable. I know it's not fair to the hops but it's only occurring on the one that's growing near the heat source (chimney). Actually, these are only ornamental/cooling devices that I planted on the South side to help shade the house ~ humulothermal cooling. All the others are A-OK, but thanks for the tip!

Can anybody identify this little sucker? Been finding quite a few on both my plants starting a week or so ago. The ladybug population has also seemed to have decreased recently as well.

this is good news indeed. I had no idea. Thanks!

Hi all. I just found some damage from a boring bug. The affected plant is Chinook and only one of the vines was damaged. From the entry point upward, the whole vine is shriveled and below is fine. As you can see, they throw out pretty long sidearms. Quite a few years ago I had a very similar problem and after 4 years of detective work found it to be European Corn Borer. This may or may not be the problem as we have no suspects at this time.

 

[Pezedorado]

The long rectangular bore looks like cicada damage.

 

[B-Hoppy]

That could have given whatever got inside the vine an easy entry point but the entire pith between nodes was tunneled out. Real similar to what happened in the past. I'll keep an eye out.

Any idea what this was?:

question mark caterpillar, maybe

This was a caterpillar about 2 become 2 catterpillars

It looks like this one http://pawild.net/home/gallery.php?photo_id=7391&p=view_photo Here is a guide to Pa caterpillars http://pawild.net/home/gallery.php?cat_id=88&p=view_cat&page=4 Cheers Glen

You are quite correct. Tell him what he won, Johnny...

hey guys found a couple spiders on my hops, and one even has a nest. Not sure if they are mites or not, and one leaf seems to have a some sort of white mold unsure if related. any suggestions?

 

[FuzzeWuzze]

Also have some bugs im curious about.

I live near a wetland/marsh area across the street so there's a whole host of bugs...but these always seem to be around my garden.

 

[theredben]

hungry4hops - Those are just regular spiders, nothing to worry about. Mites are much smaller, around the size of a pencil tip. The white growth on your leaf is not powdery mildew, but it may just be Botrytis growing on already dead leaf tissue. Is the humidity quite high where you are?

FuzzeWuzze - Looks like a random fly to me. I would not give it a second thought.

Yea I wasnt sure, only took a pic because it looks more like a flying ant than anything

 

[FuzzeWuzze]

What about these? Pretty sure this is an aphid shell, it didnt move at all...or maybe was asleep i dont know.

So far there are only a limited amount of them, ive spotted maybe one per leaf if that. Also spotted this white dot, not sure if its an Egg of an Aphid or something else..

 

[theredben]

FuzzeWuzze - The first pic is an aphid. If the levels are low, I would not be concerned. A plant can handle a significant number of aphids before any damage becomes apparent. Also, local beneficial insects need to have a low level to feed on.

The second picture could be anything from spider eggs to catapillar eggs, to beneficial insects. Nothing to worry about at this point.

Hi,

These are third generation plants that have never had any problems but all of a sudden this past week the leaves have started turning and a base vine on each plant is turning a dark red. We spotted the tiny little yellowish orangeish guys seen in the first two pictures crawling all over the tops of all the leaves. They seem to hop real far when you try to push them off.

Are these aphids or something else?

 

[theredben]

Wernerherzog - I can't tell from the pictures, but the insects you describe could be leafhoppers. Leafhoppers are similar to aphids, since they suck plant sap, but they are extremely mobile, and cannot be controlled by regular insecticides. Luckily they are nothing to worry about, as they only leave a few yellow spots on your leaves. The only other possibility would be spider mites, but those would be visible on the underside of the leaf. Spider mites look like extremely small spiders (~1mm), and live in large colonies. If you have a spider mite infestation, you will see webbing around the colony. If you do not see webbing with many small mites, then you problem is leafhoppers.

For the second pictures, is there any possibility of physical damage? Wind? Lawnmower/weedeater? Racoons/Deer/Other? It doesn't look insect or disease related.

 

[Wernerherzog]

I suppose it could be wind damage as I'm in Chicago, but this hasn't happened in the previous two years of the plant's lives, so I'm skeptical that they'd be so damaged when they've grown much stronger and heftier this year than in previous years.

 

[DubBrew]

Anyone have any clue what these are? There are lots of bugs clustered together here along with some eggs.

Ladybugs if you are lucky... http://www.butterflyfunfacts.com/ladybug-lifecycle.php

Something detrimental to the health of your plant if you are not.
