any creative growers out there with any ideas on dealing with hemp borers? second time I've been hit by them, and as far as I can tell the only answer still is kill the infected branches. NO CHEMICALS!!

Hi! If you want to go 100% natural, companion planting is your best bet – try planting mint, lavender, or basil around your grow space. These herbs act as natural repellents for many pests. However, if the infestation is already there, I’ve had great success with 'Total Explosion'. It’s a bio-based spray, so it’s safe but much more effective for an active problem. Good luck! ?🌱

well if you can't do anything effective... maybe pray? if it's in vege phase and you use something that is non-systemic, it is not danagerous... at least as far as smoking the flower that will develop later on. Also, everything has a chemical formula so does that make everything a chemical?

Unfortunately, once hemp borers get inside the stem, there isn't really a reliable non-chemical cure. The best approach is to inspect plants frequently, remove and destroy any infested branches as soon as you spot them, and keep the grow area clean of plant debris. At the end of the season, remove all leftover stalks because the larvae can overwinter inside them. For prevention next season, many growers use insect netting during moth activity, encourage beneficial insects, and monitor for eggs before the larvae bore into the stems. Once they're inside the stem, they're very difficult to reach without causing more damage. I hope you can save most of your plants. Good luck, my friend! 💚🌱

Ultraviolet_answered grow question 5d ago
Eurasian hemp borer larvae fluoresce when exposed to UV-A/Blacklight @ around 365 nm. Shine an ultraviolet light over your hemp plants at night in total darkness. Larvae (destroy) The larvae will glow an iridescent bright green or pinkish-purple, making them incredibly easy to spot and handpick. Adult caterpillar (borer) CANT GET EM! Moth (UV bug zapper). Moths are incredibly easy to lure into UV traps. Because the Eurasian hemp borer spends almost its entire life cycle protected inside the stem, surface treatments are ineffective once the plant is infested. You simply cannot control all 3 stages of the life cycle, but if you control 2 of the 3 they will only live one generation. Dealing with the problems indoors is different from outdoors.

not sure if it is true or not as I dont mess with outdoor crops because washing my crop before drying it feels bad but...you could try to train them into a trapped spot. then you have a dead bug in your stem? idk bro. not gonna have a happy ending on this one IMO. best bet is prolly to get mad about it and go scorched earth on caring for your grow space in preparation of next year. PNWUS.... might not be your space though, could easily be the forest over the way or your neighbors if you have any what advice are you gonna get that is gonna be a non-chemical solution to opening up your stems, doing surgical extraction of all bugs, taking a microscope to every square nanometer of the plant surface looking for younger stages, and then repair the plant...and still save your flower? that is wild. and what IPM tek is going to even be able to hit that species that isnt prohibitively expensive/likely fungal predation of the bugs

Hey grower, Are you a indoor grower or a outdoor grower? (I assume outdoor) due to the buglife happening. I would start working with Nematodes, predatory mites and ladybugs to create an environment that works for your plants. Hope this helps. PS: Nematodes if its indoor too.

Bom dia... Não ha muito a fazer... Remover as zonas infetadas e colocar uma rede para impedir a colocação de novos ovos... Alho e pimenta tambem atuam como repelente natural....
