Safer® Brand Garden Dust - 8oz.
This pest control product is very effective in killing caterpillars and worms, including corn earworm, bollworm, armyworm, diamondback moth, green cloverworm, hornworms, loopers, melonworm, pickleworm, tomato fruitworm, tobacco budworm, salt marsh caterpillar, mimosa webworm, and imported cabbageworm!

The Safer® Brand Garden Dust utilizes bacillus thuringiensis (var. kurstaki) which, once ingested by the wayward pest, kills them within a few days.
It is recommended that this product be applied late in the afternoon or on cloudy days since B.t. breaks down in the sunlight.
When the B.t. is ingested by the worm, it works as a gut rot poison that makes the worm stop feeding. The caterpillar or worm will stop feeding immediately and die within days of malnutrition.
Carefully read and follow all directions on the product's label. B.T. is very specific and only works on caterpillars and leaf feeding worms.
It will not harm beneficial insects, children, pets or wildlife.
It is recommended with any pesticide to test plants for sensitivity to the product. Spray a small section of the plant in an inconspicuous area and wait 24 hours before full coverage.
Application Rates:
- Apply Safer® Brand Garden Dust when pests are first noticed and repeat every 7-10 days or as necessary. Caterpillar egg hatch can occur over an extended period of time.
- Monitor treated areas for the prescence of newly hatched pests and retreat if necessary.
- Thorough leaf coverage is necessary for effective control. After ingesting a treated portion of the leaf, caterpillars stop feeding in a few hours and death occurs in a few days.
- Apply at a rate of 2 to 3 ounces per 50 feet of row planting.

This stuff works 100%. It killed all of the hornworms on my tomato plants

In an earlier review, I described our successful use of this product to save brussels sprout plants from being ravaged by cabbage moth larvae. These little stinkers infect all cruciferous vegetables. Years ago i stopped trying to grow broccoli and cauliflower because of them. Now, thanks to this Safer product containing an effective strain of bacillus thuringiensis, I am looking forward to growing both next Spring.
Since my last review I have learned with the brussels sprout plants, which have become gigantic, that you can use the Safer dust sparingly. The plants grow principally at the tender end of their stalk. That is favored by the cabbage worms, so it is the only part of the plant that you need dust. Dust at dusk (Bt is killed by sunlight) when you start seeing worm damage at the tender young leaves. Before sunup the little stinkers will be on death's door. The cabbage moths will lay more eggs, but it typically takes a couple weeks before you start seeing damage at the tender end leaves and have to redust.

This product is excellent in getting rid of hornworms (tomato worms). They were killing our vines even though we were hand picking the worms daily. Garden Dust got rid of the hornworms yet didn't affect any of the beneficial insects. Great product, though it is a little messy in the application.

We tried a preparation containing bacillus thuringienesis (Bt) 10-15 years ago to kill grubs in the lawn. It was a failure. I later read that manufacturers were shipping dead preparations. (Bt is a family of bacteria living naturally in soil. The bacteria in the preparation must be live to be useful.)
Now (June 2011) we had cabbage worms eating the leaves of our young Brussels sprout plants. Extension services recommended Bt, so we bought this product. It worked! The directions are not very thorough, but the package is a very effective dust sprayer. Shake the package, aim the orifice and give the bottle a good steady squeeze and you get a nice dust spray. Focus on the new buds. Our plants are doing fine without worm damage in the new growth a week after treatment.

I've had to use it three times in 10 days - it does the job though

The dust really worked to stop the tomato worms from eating my pepper and tomato plants - once I figured how to use it.
A simple hold-it-flat-to-puff would have been helpful.
