Description
: Monarch (Protein hydrolysate) is a category of plant Bio stimulants defined as ‘mixtures of polypeptides, oligopeptides and amino acids that are manufactured from protein sources using partial hydrolysis.
Application
: Application of Monarch to plant leaves and roots has been shown to increase Fe and N metabolism, nutrient uptake, and water and nutrient use efficiencies for both macro and microelements.
Mode Of Action
: Application of Monarch to plant leaves and roots has been shown to increase Fe and N metabolism, nutrient uptake, and water and nutrient use efficiencies for both macro and microelements.
Features
: The higher nutrient uptake in Monarch -treated plants has been attributed to (1) an increase in soil microbial activity and soil enzymatic activities, (2) improvement of micronutrient mobility and solubility, in particular Fe, Zn, Mn and Cu, (3) modifications in the root architecture of plants, in particular root length, density and number of lateral roots and, (4) an increase in nitrate reductase, glutamine synthetase and Fe (III)-chelate reductase activities.
Monarch have been shown not only to improve plant nutrition but also the quality of fruits and vegetables in terms of phytochemicals (i.e., carotenoids, flavonoids, polyphenols).
Monarch application has been also been shown to avoid or reduce losses in production caused by unfavourable soil conditions and environmental stresses. These include thermal stress, salinity, drought, alkalinity, and nutrient deficiency.
The maximum benefits from Monarch are obtained at very low dosages and are dependent on species/cultivar, environmental conditions, phenological stages, time and mode of applications (foliar vs. root) and leaf permeability to the bio stimulant.
No phytotoxicity and growth reduction with Monarch.
Monarch can increase soil fertility and soil microbial activities, thereby indirectly affecting plant growth and productivity.
Some amino acids in Monarch have chelating properties and can serve as protectants against heavy-metal-induced stress, while others contribute to micronutrient acquisition and mobility.
