Product Introduction :
Btk is a naturally occurring soil bacteria ideal for controlling tent caterpillars, gypsy moth, cabbage looper, tomato hornworm and other leaf eating caterpillars on trees, shrubs, tomatoes and other vegetables. Bt-k is most effective when applied to caterpillars during their 1st and 2nd instars, when they are still small. It must be ingested by the insect, as it is a stomach toxin. Harmless to humans, animals and beneficial insects. Bt-k biodegrades quickly in sunlight and may require reapplication under heavy insect pressure. To maximize effectiveness apply in the late afternoon. Several vendors offer Bacillus thuringiensis kurstaki that is approved or use in organic production.
Advantages of Btk:
Caterpillars that become ill or die after ingesting Btk are not considered dangerous to birds or other animals that feed on them.
In general, sunlight and other microbes destroy Btk applied to foliage within three to five days, so Btk does not multiply or accumulate in the environment.
Perhaps most importantly, Btk does not appear to pose any significant threat to human health or to pets. Btk is often sprayed over large areas from planes or helicopters in formal gypsy moth control programs over large areas but commercial applicators or homeowners can apply Btk effectively to individual trees from the ground.
Mode of Action:
When Btk is ingested by a susceptible caterpillar, the highly alkaline environment of the caterpillar’s gut triggers the Btk bacterium to release a crystalline protein called an “endotoxin” that poisons the insect’s digestive system. The endotoxin acts by killing cells and dissolving holes in the lining of the insect’s gut. When a mixture of food, Btk spores, and digestive juices leaks through these holes into the insect’s blood, it causes a general infection that kills the caterpillar.
