We used phosphite in a liquid fertilizer blend on cranberry fields this spring (6-21-31).

It has been used as a fungicide on other crops and as we had some fruit rot last year we thought we would give it a try.

We did some experimenting by turning off several sprinkler runs in a row in individual fields to see if there is any difference at years end.

Has anyone had any experience, good or bad, with this type of product?
