The caterpillars have a gut ph of 8, this is what releases it inside the creatures. It is super important to check the ph of your application water and adjust with vinegar or citric acid. We use it on tree fruit after bloom fall. Information on the was in a book about certified Organic tree fruit growth published out of Keromeos British Columbia Canada. In our Okanagon valley. I use Btg for European Chafer beetle in turf. It will not penetrate thatch so that needs to be removed first. There is a yearly limit. Sunlight degrades all Bt quickly so pests must be present and it is best to apply in the evening. Good video!
It's only a pleasure and I'm sure you will see how BT is a total game changer when it comes to growing brassica's! Let me know how it works out for you 🌻
Nobody is suggesting getting rid of "All of our worms". However, birds do not eat cabbage white caterpillars because they taste nasty apparently according to the bantams I keep for pet control. My brassica crop was almost destroyed this year by caterpillars. I go out and check and squash twice daily on the brassicas and my beloved nasturtiums, of which I keep some very rare ones. My netted rocket crop was completely destroyed because I missed spotting a problem. I leave swathes of nettles for the butterflies to lay eggs on. I don't have a tidy garden and am nature friendly. I have bumble be nests, and bee friendly plants, Buddleia bushes away from my Kale and even had house martins raise a clutch of babies in the feed store in a nest built only a foot above head height, which made entering fraught as one of them would swoop over me through the door. We developed a pattern whereby I would knock and call out "I'm coming in" then wait so they could leave if they intended to and I wasn't forced to scuttle bent over. But I will *not* tolerate caterpillars taking my food. Food on which I rely to see me through the winter. So I need to find a means of protecting my plants without having to stand outside for hours squashing caterpillars and destroying clumps of eggs. Beside, some butterflies are getting clever and not laying clumps of eggs, instead dotting a single egg randomly over the surface of a leaf. I resorted to fly papers inside the kale cage which caught lots of butterflies but made me feel terrible. If BT works, I will be using it.
Incidentally, here in the UK, we only have a few species of slug which eat vegetation. On my land I *encourage* their predators, the stunningly beautiful and huge red, black and leopard slugs by placing shelter for them in among the brassicas (also my beloved Hostas). I have next to no slug damage on the brassicas (mostly kale) nor the hostas.
Ah, you are so lucky that you have those types of predators. Here in South Africa we don't have them and the cabbage moth caterpillars are highly invasive with almost no predators. Chickens won't even eat them. I also very selectively spray my crops with BT so pretty much only brassica's. Everything else is fair game which has bought in a lot of different birds. Glad you have managed to find what works for you 🌻
Only a pleasure and yes, I only do selective applications as you need worms and bugs to increase biodiversity. It's. Just that the cabbage moth is an invasive species that is incredibly destructive. Hope it works well for you too 🌻
Hello sir! We're a group of researchers about the use of Bt strains and utilize it as a biocontrol agent for Fall Armyworms. There has been an existing study about its specific protein targeting the said worm, however, our Country is tropical and has been experiencing heat index of more than 40°C. I want to know if there's any possible way of the application when the temperature is way too high? If the application is to be done in the evening what will happen if the strain also degrades the later morning? Thank you for your response sir.
@@angelmendres hello there and thanks for leaving me a question and the detail. Personally I have not had any issues with using BT in the heat. That being said, most of the caterpillars that BT targets are on brassicas that naturally grow better in winter and the colder months. I generally only need to apply 1, maybe 2, applications of BT throughout the season as it is a living soil bacteria that lives and spreads on the leaves. I would say that if the heat is too much that your plant it going to be too stressed and bring in even more bugs. I would look at getting a shade covering of sorts to protect your plants during the worst of the heat 🌻
@@MySustainabilityJourney I understand! Thank you, I'd also like to share that I am a Student-Researcher. This bacteria is one way of controlling the worm, and reading a lot of journals stating it is ineffective once the temperature is high, it'll immediately become degraded and would stay still in the soil, therefore, becoming ineffective (as what I've read) for the Armyworms that feed the leaves, and almost everything down to the corn. I'd like to know if it won't damage anything if I apply it (in vitro) once in three-two days. Or would it be promising to just apply it for once? And, that's why covering the field won't necessarily be effective in our heat condition as we're not looking up for a garden, but rather farms of different places. Thank you so much for the reply, and your ideas. Highly appreciated!
I've decided not to use BT or neem anymore. What I do is grow a batch of chinese cabbage (multi-sow) and leave that to the cabbage moth. Then grow a lot of other brassicas interspersed with onion, marigolds, nasturtium, garlic, basil and similar to mask them a bit and so far, besides a few scarlet tatsoi, the rest of my brassicas are looking good. Much better than last year. Will see how it goes.
Hey Caz, that's very respectable and please let me know how it goes? I have done the interplanting Nx it works a charm, I just don't have the space right down for sacrifice brassica's because they already demand so much space. BT is just so incredibly effective and can be used so selectively, but yes, give full natural a go 🌻
Good question and luckily it's nice and easy. You just mix the powder with the required amount of water and that's it. You use different amounts of powder depending on the pest you are trying to keep away 🌻
Can you tell me if BT can be used to kill cabbage bats my name is Ian Grant first time watching your video I'm a small farmer who live in Jamaica looking for your response
Hey Ian, sorry I have never heard of a cabbage bat before. I know it is highly effective against the cabbage moth ans other catipillars. I'm not sure if this helps or not...🌻
Ah no, that sucks, so sorry to hear 😞 yeah BT will sort out that problem quickly without causing damage to any beneficial insects or bees in the area 🌻
Ah, I really really wish it did, but I have tested extensively and it doesn't 😞 you will need some sort of iron product for those critters. I'm so glad you enjoyed this video and got value out of it 🌻
the dreaded white cabbage moth is why im here lol. if anyone in Australia is looking for this, bunnings stocks Yates Dipel spray, Dipel is their trade name for BT to target caterpillars.
Amazing, thanks so much for sharing your local knowledge to help your fellow growers down under find this incredible solution to the pesky cabbage moth 🌻
Good question! Once the leaf miners are in the leaves it won't work, however, if you have the BT sprayed on the plant when the moth lays its eggs and the worm chew through the leaf layer then it will work, so it's a really good preventative option, but it won't help if you have them already established 🌻
Where about are you located? This will determine what options there might be. Here in South Africa it is called "Margaret Roberts Biological Caterpillar Insecticide" and is sold online and at many nurseries. I think there will be many names it goes under but as long as the active ingredient is "Bacillus Thuringiensis (BT)" you will have what works for these pesky cabbage worms 🌻
This video is unnecessarily long, boring and drawn out. You could have fitted all that into 5 minutes if you tried, I couldn't be bothered to even get to the end! I went elsewhere to get the info I needed.
Luckily we all have the freedom to make our own choices and use the chapters provided to find what we are looking for. Thanks for taking even more time to leave a comment 😁

I'm sure it can, but I'm not sure what pest you would want to target. I would love to know more... 🌻
what about leaf miners ? i have both caterpillars and leaf miners .

That's why God created Amazon.
BT is pretty old tech. You can find other brands of insecticide that contain BT as the active ingredient.
