Answer 2

Here are some Disadvantages and Advantages Of Bacilium thuringuises (Bt) :-

Disadvantages:-

# Bt insecticides have a shorter shelf life than other synthetic insecticides. Generally after two or three years their efectiveness is reduced greatly. The optimal storage conditions for Bt products are cool, dry air and out of direct
sunlight.

# Many strains are susceptible to the sunlight and their potency will degrade
within a week. Some newer strains used on leaf beetles can become ineffective within 24 hours. Also, because Bt insecticides are highly specific, many varieties must be used if you want to fully protect your crops. They just won't be that effective on crops that have multiple pests. Because Bt insecticides are only useful when their are eaten,sometimes they are ineffective because some insects such as codling moth don't get the chance to eat it.
