Welcome to today’s daily kōrero!
Anyone can make the thread, first in first served. If you are here on a day and there’s no daily thread, feel free to create it!
Anyway, it’s just a chance to talk about your day, what you have planned, what you have done, etc.
So, how’s it going?
Where do you get your BT from? I’ve heard of it before, but I feel for a small area preventing them laying eggs in the first place is easier than having to spray when new caterpillar’s emerge. IIRC it doesn’t do anything until they are already hatched and eating the plant right?
Dipel was the product I couldn’t remember the name of, but I can’t find it for sale in New Zealand.
I found it on an Aussie Bunning’s website: Yates 40g Natures Way Caterpillar Killer Dipel Insecticide but that’s not helpful :(
I bought 1kg a couple of years ago, which will last me the rest of my life as long as it doesn’t go off - I store it in a cool, dark, dry place. Have only used 20 - 30 grams in the last 3 years.
When I bought it, it was called Bactur Organic from SprayShop. It looks like that has been discontinued and replaced with Genius BT.
This was the most economical way to buy it for me at the time. It has gone up considerably by the looks. If you’ve got friends who garden, you could share it around to spread the cost - it goes a long way.
I think there is another more generic brand that sells it, but I can’t remember what it’s called, and they sell very small quantities for the price.
IIRC => Yep, BT produces a protein that blocks the digestive system of the insect/caterpillar, effectively starving it - we don’t see any meaningful loss at all. It is not supposed to harm other beneficial insects, and that appears to be true - we don’t spray it on bees, but haven’t seen any dead bees or reduced bee numbers with its use.
Ah thanks at least there’s a place to get it. I have seen small sachets of it sold in M10/Bunnings before, but the price for the small amount wasn’t worth it.
I might consider getting the GeniusBT later on in Spring, just to give it a try :)
