AF Boron

Highly efficient foliar Boron

    • Boron in soil is minute, but among micronutrients, Boron deficiency in plants is the most common. AF Boron is a highly efficient liquid foliar product designed to aid cell wall formation and stability, maintenance of structural and functional integrity of biological membranes and movement of sugar or energy into growing parts of plants. Produced using a unique process of production, via the Flex Fertiliser System ApS, AF Boron contains a true amide complex that increases the uptake and efficiency of trace elements to the crop.

Looking for Boron deficiencies

Boron deficiency occurs in many crops and on a wide range of soil types. There is a fine line between deficiency and toxicity, so it is important to apply the correct amount of Boron at the right rate using the right source. The primary factors affecting Boron availability are soil pH and soil moisture. Crop production on dry soils with pH >6.5 should be identified as being at greatest risk of Boron deficiency.

The first signs of Boron deficiency in plants are normally first visible in the new growth. Leaves will yellow and growing tips will wither. Under severe Boron deficiency, stunted development and death of meristematic growing points are common. Other common reactions include reduced root elongation and failure of flowers to set seeds. Low Boron supply may also adversely affect pollination and seed set, without visible leaf deficiency symptoms.

If in doubt, take a tissue analysis.

The importance of Boron

  • Boron helps control the transport of sugars in plants. It is important to cell division and seed development. As a micronutrient, the amount of Boron in soil is minute, but among micronutrients, Boron deficiency in plants is the most common.
  • Boron uptake by plants is controlled by the Boron level in soil solution rather than the total Boron content in soil. Boron uptake is a passive (non-metabolic) process. It moves with water in the plant tissues and accumulates in the leaves; therefore Boron uptake and accumulation are directly dependant on the rate of transpiration.

Application

DIRECTIONS FOR USE

IMPORTANT: This information is approved as part of the product label. All instructions within this section must be read carefully in order to obtain safe and successful use of this product.

For best results of nutritional uptake, apply in the evening or early morning. Do not spray when the crop is in stressed conditions such as very hot weather or drought.

Shake the container well before opening and use. Spray equipment should always be clean before adding product.

COMPATIBILITY: Do NOT mix with Phosphates or Sulphates. For details of compatibilities contact your distributor or local AIVA FERTILISER representative. Carry out a jar test before adding to a new mix.

FOLIAR APPLICATIONS

MIXING: Half fill the spray tank with water, begin agitation and add the required quantity of AF BORON* to the tank. Rinse container thoroughly and then add the rinsing to the sprayer. Once mixed, continue agitation until spraying is complete and spray without delay. It is not advised to leave products in the tank for long periods of time. *Mix into the tank last when used alongside pesticides.

TIMING: Apply as necessary, higher rates may be needed in very severe deficiency.
DOSE RATE: 2-5 L/ha
WATER RATE: 100-200 L/ha

Developed using the Flex Fertilizer System

Aiva Fertiliser uses Flex Fertilizer System technology where the liquid fertiliser contains nutrients in a form that can be taken up by the leaves and utilised by plants highly efficiently. The nutrient content is put into complex compounds using complex chemistry. This formulation results in nutrients being kept available to the plants for a longer period of time and are not lost to leaching or evaporation to the same extent as traditional fertilisers.
