Holding my marijuana leaves up to the light reveals small trails, but no culprit. What is this all about?
Thrips are tiny insects (about 1/16-inch long) that infiltrate the leaf tissue and mine it. That’s what you have. Thrips don’t reproduce quite as fast as others, but, if there are only a couple of weeks prior to harvest and you have a small infestation, you can’t really do anything. Young marijuana plants, however, stand a chance. You can treat them with pyrethrum, Botanigard, or Cinnamite.
You can control thrips with a tag team of beneficial nematodes and pirate bugs. You can get these predatory bugs at Nature’s Control (www.naturescontrol.com), inventories, and a few garden shops. Nematodes will eat the larvae and eggs of thrips while they’re in the soil and pirate bugs take out the thrips themselves. The pirate bug (or Orius sp.) is predatory and about 1/20-inch long. Adults as well as nymphs have a “piercing/sucking beak” that they use to pierce their prey and suck them dry. Although Orius prefers the larvae of thrips, many adults will also be pierced and killed. An adult Orius can consume between 5 and 20 thrips larvae every day, and larger thrips infestations produce even more kills per day. Combining pirate bugs and nematodes is highly effective as a control measure. You really only need one application of these insects to stop the infestation.
Not sure what kind of bug this is! Can someone tell me what they think? It’s not a spider mite. My leaves on my plant seem to look like dried milk in some areas of the leaves. It this a Thrip?
@Duke1 I think your answer might be whatever it is he is talking about it sure certainly kind a looks like it doesn’t it sure does to me but I could be wrong
@Hogmaster yes I think they are Thrip! I’m running out this morning to get something to kill those suckers!!! I’ll be wicked pissed off after all the hard work!!! I put into this new obsession I have lol.
@bob31 i think I have two posts going I apologize I don’t know what I’m doing. To your earlier question about how many plants I have!! I have the big clone which has been in veg since January I also have 3 cutting that just rooted a week ago. My neighbor gave me a little seedling auto flower. So all and all I have 5 and I still have one cutting In my humidity dome waiting to root. I have a 2x4 tent. I’m just waiting till the weather warms up for real to put them outside. I like outside growing the best!! Have you ever heard of montery garden spray with spinosad?
I was at a my local grow store and brought in a couple of leaves in a sealed baggie. The owner is great and was able to definitely identify what they are. They are thrips!!! Hopefully the Monterey will kill those things.
sounds good. They will probably require multiple treatments maybe let us know what the label says so we can be sure that procedure is compatible with these plants?
I have good news!!!i think they are goners. Don’t see any moving just dead ones. One more spray Wednesday and I think I should be good. The spray I used was montery garden spray with spinosad and it’s organic!!! Seems to work really well so far.
I’m not sure she’s getting tall and fat!!! I only have a small 2x4 tent and I have my clones in there and a Autoflower seedling that my neighbor gave me. I’m going to need a bigger tent. I don’t see that happening anytime soon. I’m thinking of giving some of the clones away. I’m getting clone happy!! Here is the mom and her clones and the auto is in the back right.
You’ve got a couple 300 watt LED looks like from the pic. Those will work. Your gonna need to go to a 12/12 light schedule to bring the flowering on so unless u get another tent you are gonna have to wait untill they can all go 12/12
