[QUOTE="bigbluegrass, post: 1808247, member: 15537"] Can a state allow a restriction that the EPA doesn't? My understanding is/was that a state can be more restrictive, but if the EPA doesn't allow some pesticide or insecticide application, the state can't permit its use in that exact same way. Maybe, regarding the use of Permethrin applied directly to livestock the Permethrin label is referring to the 38.4% product (which is what the linked PDF is related to). Ultra boss is diluted to 5%. However, if you look at the ASTRO label linked above (my first post) which is 36.8% Permethrin and it doesn't list any of the livestock or feed, hay and cover crop restrictions that are listed in the Permethrin label and it lists many of the exact same applications. I didn't convert the application rates to see if or how they differ - one is product per acre and the other is product per gallon and SF. However, I suspect the difference is actually that Permethrin did not do any research related to and did not pay the EPA to look at the application of their product directly to an animal, so they needed to add a restriction to the label. However, Ultraboss specifically researched and asked the EPA to look at the application of their product to an animal and therefore they are allowed to list it on their label. ASTRO paid and researched the use specifically related to fruit trees, lawns, etc. As a result, we end up with the confusing restrictions with products that all have the same active ingredient.
