Product description

BIO-PROTAN®Microfoliar PWD is a compound of micronutrients complexed to organic molecules produced by hydrolysis of natural protein. The formulation of naturally chelated micronutrients and amino acids (the organic molecules and “building blocks” from which proteins are made) helps for the prevention of micronutrient deficiency stimulating simultaneously the metabolism of the plant. Microfoliar is a multifunctional product performing at the same time as fertilizer (organic nitrogen content), deficiency corrector (balanced pool of micronutrients) and bio-stimulant (free amino acids promote rapid recovery in the event of stress).

BIO-PROTAN®Microfoliar PWD bio-stimulant effect depends from the molecular size of natural amino acids contained in the product. Amino acids (the smallest organic molecules in the compound) are quickly absorbed by the leafs and tissues of the plant where they are used for the production of proteins and sugar, enzymes and plant growth regulators, increasing vegetative activity, stress resistance and quality of the agricultural production.

Beyond the positive influence on plant vegetative development and the recommendation to use Microfoliar amino acids particularly on stress situations, amino acids do interact with microelements as well. Amino acids are natural chelates able to ligate (“link”) with microelements and form a metal complex. Amino acids are also very effective in conveying the linked microelements through the cells to the sites of utilization, helping to overcome chemical and physical barriers of the leaf cuticle, the cell wall and the lymphatic system. Combining microelements and amino acids in foliar spray solutions leads to an increase of micronutrient-treatment efficacy and reduces the fertilizer application dose.

BIO-PROTAN®Microfoliar PWD provides microelements with high bioavailability and is therefore an indispensable accompaniment to the basic fertilization in citrus trees and other fruit crops with high demand of essential micronutrients. We recommend BIO-PROTAN®Microfoliar PWD for the prevention of micronutrient deficiency, to support the chlorophyll and carbohydrate production and increase the photosynthesis process. The use of Microfoliar prevents sulphur deficiency chlorosis, stimulates fruit swelling and diminish the early fruit drop off.

BIO-PROTAN®Microfoliar PWD is water soluble without any precipitation that could clog filters and nozzles of the irrigation system and is free from any chemical components that could be harmful to the soil and crops.

Directions for use

L/ha / application
Fruit trees (citrus, stone fruit, pome fruit, fresh fruit) From vegetative regrowth to fruit set,
2-3 applications every 15-20 days
1-2 kg/ha
Kiwi, wine and table grape From fruit set, 2-3 applications every 15-20 days 1-2 kg/ha
Olive trees 2-3 applications every 15-20 days until the disappearance of the symptoms of deficiency 1-2 kg/ha

Dilute BIO-PROTAN®Microfoliar PWD before using it on plants. 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 crop, crop vegetative cycle, climatic conditions and average yields expected.

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.

Handling and storage

  • Read carefully the safety data sheet before use.
  • Dry and cool storage recommended. Close properly the bag after use to avoid material caking.
  • Shelf life in well-closed original packaging min. 2 years.
