Thuricide HPC BT 8oz Caterpillar & Worm Control

I was very doubtful about how effective this would be. Its just incredible - I did one good application 3 weeks about and no more caterpillars and no need to net the cabbages. Fantastic stuff, buy this, it will change or gardening for ever.

Very effective on an infestation of caterpillars (Large white butterfly) which was caught relatively early on Brussel sprouts. A single application has cleaned them out within a couple of days of spraying. Good product.

It works by coating caterpiller food, leaves, with a bacteria that once ingested stops them feeding. Doesn’t affect human consumption of apples. Ony method we could find that was not toxic to humans and dogs.

A bottle of liquid Thuricide - Bacillus thuringiensis aizawai (Bta). It is 237ml (8oz) of concentrated Bta for easy mix with water in sprayer unit. Add the water, the Thruicide, mix will, pump with pressure, and spray. The Bta kills the larvae so do not grow. This is very organic as it uses the Bta found in soil that has been mass produced. I spray twice a year for excellent coverage as it has good longevity in keeping them at bay. An excellent value for a healthy garden.

Spotted some caterpillars on my cabbages. Sprayed it on. Then they were gone. Haven’t noticed any serious health effects so fingers crossed.

Why did you choose this product over others?: Environmentally better and bio specific. Expensive though.

Great product.

Definitely had the green caterpillars in my box hedging as I spotted some of them munching my lovely green hedge. Just about to apply second treatment and I can’t find any of the little blighters

This saved my leafy greens! 1 teaspoon per quart of water in an electric sprayer. I grew many varieties of leafy greens this summer, mostly from the cabbage family, and cabbage worms were devastating them until I got this product. Those darn worms are nearly invisible until they've eaten through all your leaves. I had a planter full of watercress that was reduced to nothing but stems, and after picking off the by then large green worms and spraying the remaining leaves and stems as well as soaking the soil with this diluted product, my plant came back healthy and happy. At various times, the worms also attacked my arugula, all the different kinds of mustards I was growing, my nasturtiums... pretty much everything. Given that my plants are up on a second floor balcony, I was kind of surprised by this, but I had to fight these worms off all summer long. I did find that I needed to use this repeatedly, basically every time it rained, and sometimes even during periods of drought. It's definitely not a one-time cure--you have to be vigilant about it. The worms start out so small they are practically invisible, and even when fairly large I have trouble seeing them on casual inspection. I dilute 1 teaspoon of this in a quart of water and put it in an electric sprayer. I find that manual sprayers tire my hands too much for the amount of spraying this requires. First I turn over the leaves and spray their undersides. Then I spray the tops and finally the soil. Whatever is left after treating the plants I use to water the soil. The best thing for pests would be to use netting that doesn't touch the plants so the pretty little "butterflies" can't lay their eggs, but for my container plants that is really impractical. That works more for people growing in the ground in beds or rows. Unfortunately, this seems to have no effect on aphids, which I am now battling. I do have a ton of this left, even after using it all summer on a small porch garden.

Cost effective compared to other bacterial products , and it killed my army worm infestation.

I had researched what I needed to keep the bud worms from eating my petunias , and was recommended this, it works great , my flowers look beautiful this year. This BT spray is a very small bottle , but you only 2 ozs per gallon mixed with water , and I spray my flowers using a gallon pump sprayer , so much easier and good coverage , you don’t want to mix up too much at a time because you don’t want it sitting in too much heat, so I pretty much make up what I’m just going to use so I’m guaranteed the effectiveness of it. So the bottle is small but goes along ways , totally worth the price . I spray at night only when there is no sun, I make sure I first the buds and the soil inside my flower pot, without this product , my petunias would have been eaten by those nasty bud worms , this is a great product and I would recommend this to anyone who wants beautiful petunias!

Good stuff.

When I applied this product to my cabbage, it seemed to just roll off like the cabbage was water proof. So I wondered how could it possibly do anything to stop the worms from eating it. But as I harvest to make sauerkraut, I'm seeing the cleanest cabbage heads I've ever pulled. You can see a few holes in the leaves here, but they were there before I sprayed the product on . After I sprayed there were no new holes, and when I harvest, there's no sign of loopers in the heads. No slugs or earth worms either. This little bottle of BT is concentrated so I should get at least 4-5 seasons out of it, because I only used about a liter of spray this season. That includes using it on broccoli and cauliflower, and a few flowers that had leaf miners. I should say, this product is not intended for aphids and leaf miners, but it seems to work on them.
