Southern Ag100520028 13021 Caterpillar Control, 8 oz

Great stuff if you run an organic farm

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.

I can't speak to the effectiveness of this product, but I assume it contains the concentration of Btk it says—YMMV with your particular pest, as always. I'm using it for squash vine borers on zucchini, which I understand can be a marginal use-case, and—fortunately overall, but still—after seeing (and drowning) one adult in late June I've seen no sign of them, so it's possible there've been no caterpillars to be killed.I'm knocking off one star because the child-safe cap (a) requires a lot of downforce even after initially breaking it loose, and (b) is easy to misthread when putting it back on—in which case it doesn't quite seal. I opened mine the second or third time, after a week since last use, to find mold growing on the paper sealing disc under the cap, which I hope has not contaminated the product enough to impact its effectiveness. I had to throw out the paper disc, but had the (I think) clever idea of replacing it with a garden-hose O-ring, which is just the right size. There's still (barely) enough thread engagement for the cap to seal tightly, and it seems like this should be a lot more watertight as well in case the bottle gets knocked over.

This product arrived smaller than I expected but that is my fault because I didn't carefully read the description. However, I've been using it for a number of years with much success. I have been consistently using it in a pressure washer during caterpillar season. By using the pressure washer, I feel that it dilutes nicely and I'm able to spray high up into the trees.

We live in Northern Wisconsin. Our large Balsam Trees have Budworm. We sprayed our trees just as the first worms were emerging. The worm has to eat the bud with spray on it before it will die. Timing is very important.This spray really works. Our trees are beautiful.It is safe for birds , animals and humans.

My huge pot of hanging petunias suddenly started getting little black specks on them. Next they were being eaten with big holes in them. I saw a green worm and decided to find out how to save the plant. I saw a lady on Youtube that used this product and showed how her petunias came back after using his produt. So I decided to give it a try. I mixed 4 teaspoons in a gallon of water and sprayed it with a sprayer. Within a week, my plant started to look great again. I just sprayed again today to make sure the worms do’t return. It is a natural spray that won’t hurt nature or humans. I am very happy with his product!

I spray this on my passion flower vine to take care of the gulf fritillary butterfly caterpillars. I haven't seen any caterpillars since I started using this. Prior to using this, the plant had plenty of caterpillars on it.

Though they're not a caterpillar, it cleared up fungus gnats in houseplant soil in just a few days by attacking the larvae.Update 3/24/15Well, I'm not sure if it went bad, got too cold during shipping, or what, but it's not really working for me any longer against fungus gnats after a generation or two. I guess they can develop immunity?It seemed to work really well after the first application, but upon reinfestation from a different pot in the house they gnats aren't seeming too bothered by following applications despite drenching the soil in bacterial culture.Developed immunity? Not sure, but it's not taking care of my fungus gnats any more. I only tried it because i heard it was helpful, so I'm sure it works for some people out there. Try not to get it delivered in the cold, and hopefully you'll have better luck than me!
