yes it will make ur foliar more effective by making the nutrients stick to the leaves as budman111 said but its overpriced..i use the same exact thing except mine is from grow more and its called E-Z wet SE which is yucca extract..if u got the wet betty go on and use it up and then buy the grow more product if u plan to foliar feed..yucca extract is actually good for ur soil and microbiology..just google yucca extract and check out what it does for the microbes.
