What it does

Xylem Plus is a systemic fungicide for the control of Phytophthora, Pythium, mildew, rot and other listed diseases on agricultural crops.

Applied in-furrow, Xylem Plus helps kick-start seedlings by allowing better nutrient flow. Applied foliar, it is absorbed through the leaves and moves through the plant down to the root tissues.

Benefits

Source: Xylem Plus brochure

  • Systemically active in the xylem and phloem of the plant, through patented poly-phosphite technology
  • Up to a 60-day residual in the stalk and leaves
  • Full-season protection with two applications
  • Safe for the seeding environment when applied in-furrow
  • Can be applied to Roundup Ready crops at planting, with side-dress fertilizer, tank mixed with Roundup, or as a separate foliar pass (label)

Xylem works. I ran out of it with these last 100 acres to go. There are dying phylophthera spots all over in these and not a single one where I had it in starter. Same variety.
