Bio Protect is diluted before use and then applied as a foliar spray. Bio Protect works in 2 different ways: Firstly it contains naturally derived amino acids which strengthen your plant's immune systems to withstand and fight off attack. Secondly, Bio Protect contains natural essential oils which are layed down onto the leaf and actively repel bugs.
