Benefits of Kelpak on Walnuts

Kelpak trials on walnuts in California and Chile show improved fruit set and nut retention, as well as higher nut yields, resulting in excellent returns for the grower:

  • Improves rooting of nursery trees
  • Stimulates root and shoot development
  • Improves the development of new roots in spring
  • Better nut set and retention of bearing trees
  • Better nut yields

Recommended application rates.

Established trees: Apply a minimum of 3 L/ha, not more dilute than 3 L/ha of water,
2 to 3 times between catkin development and receptive pistillate stages.

Tree establishment: Apply 2 L of a 1% Kelpak solution (1 L Kelpak in 100 L water) as a soil drench directly after plant-out, or drench the nursery bag with the solution directly before plant-out. Follow up with foliar sprays of
2 L/ha Kelpak per 100 L water (0.25%) with
3 to 4 week intervals during early growth.
