Considera

Hi:

I am new. I just read the Post “Greg Willis on peppering, weeds and more” and the response posted by Mark on Dec 21, 2006 3:43 am .

My question is in regard to “he made a sugar-water solution at 16 Brix and sprayed it on his vines, the leafhoppers, both Blue Green and Glassy Winged Sharp Shooters left his vineyard. Ralph told me that he got the leaves up to 14 Brix.”

What is Brix?

Welcome aboard Jim

Degrees Brix (symbol °Bx) is a measurement of the mass ratio of dissolved sugar to water in a liquid. It is measured with a saccharimeter that measures specific gravity of a liquid or more easily with a refractometer. A 25 °Bx solution is 25% (w/w), with 25 grams of sugar per 100 grams of solution. Or, to put it another way, there are 25 grams of sucrose sugar and 75 grams of water in the 100 grams of solution.

Thanks.
