Don't know if this is what you are looking for Peter, but I have an article I got from a Cornell Cooperative Extension Publication at http://ipmguidelines.org/TreeFruits/Chapters/CH04/default-6.aspx which states:
1. It is the amount of water that changes, not the amount of pesticide per acre, or 2. The amount of pesticide reduces in proportion to the water, to maintain a constant concentration. 3. Is a standard dilute application uses 400gpa on "standard" trees but some suggest that these big old traditional trees are no longer and a modern "standard " tree should be regarded as 300 gpa.

Hi All, Has anyone come across Extension articles or peer reviewed work which discuss the use of Tree Row Volume (TRV) applications and this age old question: is it the amount of pesticide or water that changes when using TRV, especially where TRV application rates are below manufacture labeled rates for neonicotinoids, diamides, spinosyns and etc?
