Ya....wanting the 2 different terms to be the same becasue they use the same language is why the English language is hard to understand. A systemic pesticide had a very specific meaning.
Your on an English speaking web site. Interestingly enough, the meaning of "systemic and translaminar" do not change by language!
I don't know what school you went to Rusty but,
Translaminar is NOT systemic.....Although sometimes called a LOCAL systemic(it does not spread through out the plant from application point. Translaminar is the
translocation of the active chemical from point of application on the leaf surface to the bottom of the leaf structure.
The active chemical does not spread through out the whole plant structure...
Systemic is the translocation of the active ingr. through out the whole plant structure.
This comes from my collage.
Translaminar materials don’t have surface residues but move into the leaf where a reservoir of active ingredient remains for a period of time providing longer control. Don’t confuse translaminar with systemic – translaminar materials move only short distances not through the entire plant. Thorough coverage is still very important.

It should be noted that systemic insecticides are best spread through the plant by root drench. Topical applications are less effective.
Systemic insecticide effectiveness can be directly correlated to how well the active chemical is water soluble (Imid is the exception here).
After all, it's water that carries it through out the plants vascular system...
"Method of Action" on any chemical insecticide. Does in no way speak to it's toxic levels in mammals or anything else. It's simply HOW the active ingr. does it's work. I have no idea where you got your misconception.
Toxic reactions to any chemical by anything. Is simply how that organism reacts to that chemical and at what concentration.
Toxic reactions can be expressed in many ways and with many differing results...
Simply look at the 2 different tetronic acids we are talking about....
Spiromesifen - not very toxic to humans. Studies of field workers coming into high contact levels of the active ingr. Show no toxic effects.
Spirodiclofen - Far more toxic to humans. (and mammals)
You made how many posts to prove what?
You called me out...
I gave the proof on trans vs. systemic....
