is used to control caterpillars as needed. It is easy to mix and apply.
Apply by hose or pressurized sprayers, mist blowers, or aerial
application, 1/2 tsp to 4 tsp per gal of water depending on extent of
infestation. Even a little squirt bottle may be used. We
recommend that you get an ID on the caterpillar you are treating for. We
don't want to kill the caterpillars that will turn into beautiful
butterflies. The easiest way to use it is to just spray the specific
plants you want to protect like your tomatoes for tomato hornworms. If you
have planted dill to feed the Swallowtail caterpillars or milkweed to feed
the Monarch larva- don't use Thuricide on these plants.
- Use the Garden Syringe for precise
BTK applications in insect holes like squash vine borer, tree, shrub
and plant borers.
Advantages of using Thuricide
- Thuricide, unlike certain chemical insecticides, may be used anytime
a specific caterpillar appears. Treated crops may be picked,
washed and consumed the day after any Bt variety is applied.
- People and critters can return to the treated area immediately
after the spray has dried.
- The active ingredient in Thuricide, Bacillus Thuringiensis v.
Kurstaki has been proven commercially to selectively affect only leaf
BTK will not work against non-feeding stages of insect development. For
example the egg, pupae and adult stages of their life cycle. It is best
applied when the caterpillars are young and actively feeding. Cover the
upper and lower surfaces of the leaves to increase effectiveness. At
application time the leaves should be dry and no imminent rainfall is
expected. Repeat application every 7 to 10 days. If egg hatching is occurring
over an extended period of time then make a second spray application 3 to
5 days later. Pest stops feeding in a few minutes after ingesting enough
BTK. Death occurs in 3 to 5 days. BTK does not harm people, animals, birds
or fish. BTK can be applied with a hose end sprayer, pump up sprayer,
backpack sprayer or a high pressure sprayer.
