Recommended application rates

Established orchards: Apply a 0.2% Kelpak solution (200 ml Kelpak per 100 L water) 5 times using a full coverage foliar spray program, namely at 50% bloom, full bloom, 4 weeks after full bloom and 8 weeks after full bloom.

New orchards: Apply a 0.5% Kelpak solution (500 ml Kelpak per 100 L water) as a soil drench around the plant directly after transplant. A volume of 0.5 to 1 L of the mix per plant can be applied. Another option is to soak the nursery bag with the solution before planting.

Dilution: Kelpak should never be dilute more than 1:500 (0.2%); the pH of the final spray mix should not be higher than 7, and sufficiently buffered to remain below 7 until application has been completed. Do not apply at intervals of less than 14 days. The use of a surfactant is recommended when applying Kelpak.
