Bacillus thuringiensis is a microbial insecticide to provide biological control of caterpillars and various borer species. This biopesticide works by introducing bacterial spores and toxins into the body of the insect larvae as it feeds on foliage. These toxins quickly disrupt, and soon completely stop, normal digestive functions of the pest insect. The infected larvae will cease eating within minutes and fully succumb to the effects of the BTK and die within 2-5 days. Its 4 hour reentry interval (REI) makes Thuricide ideal for use on edible crops and in nurseries for control of common pest larvae like gypsy moths, armyworm, inchworms, canker-worms, tent caterpillars, cabbage looper, tomato hornworm,etc

This product is a type of crystal-producing Bacillus including many varieties. It can be used to control various pests of the order Orthoptera, Coleoptera, Diptera, Hymenoptera, especially Lepidoptera.
Bacillus thuringiensis can produce two major toxoids: endotoxin (ie parasporal crystals) and exotoxin (α, β, and γ exotoxin). Parasporal crystals are the main toxins.
In the basic gastrointestinal tract of insects, the intestine can be paralyzed within minutes, the insects stop feeding, and quickly destroy the intestinal lining, causing the vegetative cells of the bacteria to easily invade and penetrate the intestinal lining. Hemolymph, eventually insects die from starvation and sepsis.
Exotoxin has a slow effect, and it has obvious effects during molting and metamorphosis. These two periods are the peak periods of RNA synthesis. Exotoxin can inhibit DNA-dependent RNA polymerase.
The effect of this drug is slow, and the effect can only be seen in about 2 days after the pest is fed, so it should be used 2 ~ 3 days earlier than conventional chemical agents, and the effect is better in the early age of the pest.
Apply 0.75-1.5 kg per ha at first sign of egg-laying or newly-hatched worms (1st instar larvae).
Reapply at 7-14 days interval depending on plant growth rate, month activity and rainfall after application
Early morning or evening application when air is calm,
Product instantly mixes with water, Read and useaccording to application sheet
Spray leaf surfaces thoroughly, top and bottom for complete control.
Do not apply through any kind of irrigation system.
BT must be ingested by susceptible larvae to be effective, so thorough coverage of target foliage where larvae are feeding is essential.
Apply when larvae are small, newly hatched and actively feeding.
Repeat applications, according to economic threshold, as necessary to maintain control.
To improve wetting and distribution on difficult to wet foliage (e.g. crucifers), the addition of a wetting agent is recommended.
After ingestion, larvae cease feeding within a few hours and death occurs in 2-5 days.
