The relationship between boron and pollen viability is so intimate that all crops should receive a foliar application of boron prior to flowering.

Boron is the most leachable of all trace elements and consequently deficits are common. Boron is required as a calcium synergist and is very important in the early reproductive period of the crop cycle. Nutri-Key Boron Shuttle™ offers complexed boron in a balanced formulation which covers the full spectrum of background nutrition.

Key Performance

  • 3.6% B plus background nutrition
  • Superior Shuttle® chelation for enhanced uptake
  • Improve flowering and fruit-set

Growth Stage 

  • Vegetative Growth
  • Pre-flower, Flowering, Fruit Set and Fill.

Home Garden Application: Dilute 7.5 mL per 9 L watering can and apply the diluted mix at a rate of 1 litre per square metre. Do not apply more than 6 times per year without demonstrated trace element requirement.

Stir well before use. Where higher water rates are required for good foliar coverage, do not exceed maximum product rate per hectare. Sensitive foliage or plants should be test sprayed prior to full scale application. Frequencies are a guideline only and can be adjusted according to farm practices and/or in conjunction with crop monitoring. Ensure suitable spray conditions (e.g. temperature, humidity, wind- speed), prior to foliar application. Compatibility and/or performance cannot be guaranteed when combined with other products. Jar test for compatibility and spray test on small area before wide-spread use
