BLUPRINS®

Bud break promoter

BLUPRINS® is an organo-mineral fertiliser specifically designed for breaking bud dormancy.

Key Benefits

Enhance bud fertility, increase yield potential
Uniform bud burst, flowering, fruit set and harvest
Uniform shoot and fruit distribution

Key Components

Amino acids, polysaccharides, nitrogen (N)

Mode of Action

Applying BLUPRINS® promotes healthy buds for timely and uniform release from dormancy, optimising flowering, fruit set and ripening uniformity.

mimics the effects of cold exposure: due to the high calcium content, sends buds the same physiological signals for dormancy release that the plant naturally gives following adequate exposure to chilling temperatures
stimulates the resumption of bud metabolism: BLUPRINS® supplies readily available nutrients (amino acids, polysaccharides, nitrogen) which promote enzyme activity in bud tissues

Directions for Use

Cherries Apples, Pears Wine grapes, Table grapes Green Kiwifruit Golden Kiwifruit

Cherries

Target

Bud burst uniformity, Flowering uniformity, Improve fruit set, Ripening uniformity, Larger fruit

Timing

30-40 days pre-flowering

Rate

6-8 %

Critical Comments

BLUPRINS must be applied with calcium nitrate 5% of total spray volume

Calculate chilling hours (T <7.2 °C) from leaf fall to the time of application:

Cold winters (>500 chilling hours ~ 40 days pre-bud burst)

Mild winters (<500 chilling hours ~ 30 days pre-bud burst)

It is very important to ensure thorough and uniform spray coverage

Minimum total spray volume 800 L/ha

Example for BLUPRINS 8% at water rate 800 L/ha:

Add about 400 L water - keep filling
Add BLUPRINS 64 L (800 x 0.08)
Add calcium nitrate 40 kg (800 x 0.05)
Fill with water until total spray volume = 800 L

Compatibility

This product can be mixed with all common formulations; except products based on copper, sulphur, mineral oils or emulsions. A simple mixture test to check compatibilty is advisable.

Important

BLUPRINS must always be applied with BLUACT or calcium nitrate per directions
Do not use on plants younger than 3 years of age, weak or not properly lignified
Do not apply when temperatures are lower than 5°C
Any treatment with mineral oils should be carried out at least 8-10 days after the application of BLUPRINS
Avoid applying BLUPRINS (even by drifting) on vegetating or evergreen crops (including olives, citrus etc.)
Tank mix order: water (about 1/2 total volume) > calcium nitrate > BLUPRINS > water until total spray volume reached
Rinse sprayer thoroughly after use
