Bioinsecticide BTk/Bacillus Thuringiensis Kurstaki Powder

Short Description:

Bacillus thuringiensis kurstaki (Btk) is a group of bacteria used as biological control agents against lepidopterans. Btk, along with other B. thuringiensis products, is one of the most widely used biological pesticides due to its high specificity; it is effective against lepidopterans, and it has little to no effect on nontarget species. During sporulation, Btk produces a crystal protein that is lethal to lepidopteran larvae. Once ingested by the insect, the dissolution of the crystal allows the protoxin to be released. The toxin is then activated by the insect gut juice, and it begins to break down the gut.

Application

Bacillus thuringiensis var. kurstaki (Btk) controls the larva stage (caterpillars) of certain moths and butterflies such as tomato and tobacco hornworm, cabbage worms, loopers, leaf rollers, bagworms, gypsy moths, tent caterpillar, fall webworm and others. Ingestion of the bacterium paralyzes the digestive system of the insect, and it stops feeding within hours. Bt affected insects usually die within several days of ingesting the bacteria. Since Btk is most effective on young, heavily feeding larvae, insect populations must be monitored to insure that the targeted insect is in the proper stage for optimum control. Btk will not control the larva stage of sawflies. Btk may be applied up to the day of harvest on a variety of food crops. This biological/microbial insecticide is available as a dust or in a liquid concentrate form.
