Product description

DIAMIN®Plus is a liquid organic compound produced by hydrolysis of regenerative collagen protein. The product is made of peptides and amino acids in the ideal proportion for the nutrition and bio-stimulation of the plant’s basic functions. The natural balance of total and free amino acids displayed in the aminogram is proof for the absence of any synthesis free amino acids and evidence for DIAMIN®Plus naturalness.

The use of DIAMIN®Plus is possible at any time of the year but particularly recommended when the plant manages the greatest metabolic effort as in transplantation, vegetative growth, flowering, ripening and maturation. DIAMIN®Plus enhances root growth and the development of vigorous buds, induces higher flowering, pollination and fruit set. Apply regularly DIAMIN®Plus to improve the quality and quantity of your agricultural production.

We recommend the foliar application of DIAMIN®Plus before, during and just after plant stress situations such as frost, hail, salinity, drought and damages from phytotoxicities. Only a few applications support plant recovery and contribute to a remarkable increase in plant robustness.

Beyond the positive influence on the vegetative development of the plant and plant stress resistance, DIAMIN®Plus amino acids help preventing and correcting micronutrient deficiencies by improving the leaf and root absorption of microelements. Amino acids act as natural chelates and carriers through the plant tissues when applied in combination with microelement fertilizers. The chelating effect with certain amino acids such as glycine enables cation microelements like Iron, Calcium, Zinc, Manganese and Copper to „ligate“ (link) with amino acids, form a metal complex and be more easily assimilated by the plant. The carrier properties of free amino acids and short chain peptides combined with the natural chelate properties of amino acids allow DIAMIN®Plus to enhance efficacy and reduce the application doses of microelement fertilizers.

DIAMIN®Plus is made with natural, officially certified European raw materials. As a pure organic protein, it is free from any chemical components that could be harmful to the soil and crops. The homogeneity and water-solubility of the product avoid any precipitation that could clog filters and nozzles of the irrigation system.

Directions for use

DIAMIN®Plus is recommended for foliar application, fertigation and localized soil irrigation. The use as a nutritive or bio-stimulant solution requires different application dosages:

ml/hl H2O / application
L/ha / application
ml/m3 H2O / application
ORGANIC NUTRITION (up to 15 % of total Nitrogen demand) 15 – 25 L
once/week up to 6-8 times
50 – 100 ml/m3
over vegetative plant activity
BIO-STIMULATION 200 – 400 ml
every 7-10 days / 4-5 times
2 – 4 L
every 7-10 days / 4-5 times
5 – 10 ml/m3
over vegetative plant activity
NATURAL CHELATES 200 – 300 ml 2 - 3 L together with
deficiency corrector
ANTI-STRESS 400 ml just after the event
and again a few days later
4 L just after the event
and again a few days later
  • In fertigation the treatments can be repeated weekly or every 15 days to a total dose between 15-20 L/ha
  • To recover from frost damages we recommend a spray water concentration of 400 ml/100 L broth (0.4 % concentration in spray water)
  • In the greenhouse and when mixed with sulphur and trace elements apply the lowest recommended dose
  • With the exception of the olive grove avoid use in conjunction with copper, stannous, sulphur based products and mineral oils since the combination with free amino acids improves the absorption rate and can result in phytotoxicity
  • Do not use on plum for phytotoxicity risk
  • For bio-stimulation, distribute the applications during the vegetative cycle (sprouting, growth, flowering and fruiting) to achieve the best results

DIAMIN®Plus has to be diluted in irrigation water. Do not use undiluted. In case of inexperienced handling we recommend a preliminary test on small areas before extending the treatment to the entire culture. The dosages advised are purely indicative and may vary depending on the climatic conditions and average yields expected.

Handling and storage

DIAMIN®Plus is stable when stored under normal undiluted conditions. The original product in the state in which it is delivered is hazard–free concerning the transmission of pathogens. Close package properly after use and store in a frost-free place. In the case of longer storage shake well before use.
