you mean caterpillars?

Yes green fuckers hard spot till damage is done

I believe you are referring to hornworms. There is tobacco (7 stripes) and tomato (8 stripes) hornworms. I follow their frass droppings to find them. If I don't find them immediately, I continue to check the plant throughout the day. If all else fails, I use a black light at night.

If you are wanting to spray for them, I use BT for anything in caterpillar stage. Keep in mind, this will kill anything in that stage. Must be reapplied after rain.

I've only ever found them on my tomatoes. I certainly hope they aren't on your cannabis. Only thing I've seen strip a plant faster is a grasshopper.

It's hard to do once they get into the plants during flower.

Suggestions?? Saw 2 today. About as large as a pistle

This pic is zoomed 4x. Of course I've found two of these today. Are the black specks on leaf poop?

I use Monterey BT(Bacillius Thuringiensis ) next time and in the future begin at the very beginning of pre flower. Use it, i skipped 2wks and here we are.

BT.

But you have to spray early and often. At this point the worms are deep in the bud chomping and pooping, rotting out the buds. The worm has to eat the Bt, so almost impossible to get it where the worms are. You just need to do daily inspections for the telltale signs of yellow or brown sugar leaf. If you see any give it a tug. If it comes loose there’s a worm at the stem and you’ll need to cut the bud out. Make sure you get all the rot and shit or it will just keep spreading. (Better to loose 20% of your plant than 80%, so don’t skimp on culling the ruined parts.)

Also inspect for new eggs. Clear/white egg on the outside of the bud. Moth will lay tiny egg and after hatching it will roll a leaf during veg, but will head straight into the bud this time of year.

Once you have buds, I'm assuming it's too late?

Put the plants somewhere really hot maybe?

Bugs will back out but plants will survive.

Then cover them in netting?

Just a thought

 

[Organic13]

Ummmm, caterpillars in your buds eating away don't care how hot it is.

Some eggs this morning. I notice them after a heat up. Been in the 70s for weeks and then a couple days in high 80s and I see tons of Skippers all around the yard. (They’re not actually the months laying the eggs, but when you see an explosion of any of your local butterflies/months, you need to be checking for the bud worm eggs.)

Yeah pretty much. If you know you have them in your area start spraying in June/July and try to knock down the population so you’re not getting totally overwhelmed in Sept/Oct. You won’t be able to completely erratic them, but hopefully it will limit the loss.

I've not seen anymore, nor any yellow or wilted sugar leaves. I'm checking, hopeful. I've never had this problem before, nor problems with deer. This summer all hell broke loose. :/ new respect for indoor grows!! Lol

 

[Organic13]

Yeah, outdoor growers are a different breed. I don't have it in me. Got my ass handed to me. May grow a couple outside for funsies next year, but I'm probably moving indoors. I'm not built for heartache like this. Hahaha.

Glad you've not had anymore issues. Once the caterpillars arrive, it's hard to get them in check because you can't see them until it's too late. Also, doesn't help that we can't nuke our plants because they are in flower.

I've seen some great ideas on this forum for keeping deer out of your plants. Check out @Thatoneguyyouknow_ grow journal. He's in the appalachian mountains killing it. He's informative and if he has time, will help you out.

ive never had a grow where i didnt lose some flowers to these guys introducing some damage and fungi,

Imho, you are going to have some worms in flower without use of pesticides, its just part of nature. i pull a couple of these off my plants almost every time im out there.


If you grab a UV flash light and shine the plants in the dark, the caterpillar poops and chew damage will glow and it makes them a lot easier to find.


I am unwilling to spray flowering plants personally. With anything most of the time. Ime BT and Spinosad kill pistils early, they dont just redden them. that can also create late flower fungal issues too.

 

[Galgrows]

I'm fighting a loosing battle with them also. Once these take hold it's very hard to knock them out. I guess it's another lesson on growing outdoors we must begin spraying BT at first sign of preflower or even before. And all the way up till harvest. I missed 2wks during the hottest weeks and they got a grip on my buds.

I spoke too soon. I found a brown spot on a bud, dug and at first thought Bud rot, thnx Oregon. No, I found worm as well. Oke's a little further, saw another in a bud. Dug a little deeper, saw a minuscule sibling. :( fukers. I'm wondering if I should just pull the buds and ?? Crap, I don't know.

I will try the UV flashlight. They are tee tiny when they first start out. I found three different buds damaged. Cut it out, cut that branch bout half way down.
