Zn Sol B®contains vegetative cells of Starkeya novella . The composition is customised to comply with regulatory guidelines of respective countries. Starkeya novella a is a proprietary strain and compliant with National Bio Diversity Authority guidelines and has Access Benefit Sharing (ABS) agreement with the State Bio Diversity Board for payment of royalty to the habitat from where the microbes have been isolated. The strain is under Patent deposit certificate with Budapest Treaty recognised depository.
Enzyme production:Starkeya novella produces enzymes and metabolites that aid in mobilization of zinc in the soil through its unique glucose transport system
It shows a maximum induction of sulfite oxidase activity and a maximum growth rate. The glucose transport system as well as key enzymes of glucose metabolism in Starkeya novella was induced by glucose
Starkeya novella uses glucose at a slower rate in mixotrophic medium and utilizes a different primary route of glucose metabolism. Regulation of glucose metabolism in Starkeya novella could involve control of enzyme synthesis, control of enzyme activity, or both.
Energy metabolism:Starkeya novella exhibits reduction in the rate of glucose and thiosulfate utilization and a partial uncoupling of substrate oxidation from energy generation
At the high substrate concentrations employed, Starkeya novella is incapable of controlling the rate of substrate utilization to the extent necessary to attain the desired rate of energy generation and, thus, requires the additional mechanism
Zn Sol B® is available in the following formulations:

1. Mix at recommended doses with compost and apply at early life stages of crop along with other biofertilizers
2. Mix Zn Sol B® at recommended doses in sufficient water and drench soil at early leaf stage/ 2-4 leaf stage / early crop life cycle
3. Drip Irrigation: If there are insoluble particles, filter the solution and add to drip tank.
4. Long duration crops / Perennial / Orchard crops: Dissolve Zn Sol B® at recommended doses in sufficient water and apply as a drenching spray near root zone twice a year. It is recommended to have first application before the onset of the main monsoon / rainfall/ spring season and second application after the main monsoon / rainfall / autumn/ fall season.
Note:
Do not store Zn Sol B® solution for more than 24 hours after mixing in water.
A fraction of the product may not be soluble in water. It is advisable to filter and discard undissolved residue and use filtered liquid for spraying or feeding through drip irrigation.
Compatible with biofertilizers, organic fertilizers, organic manures, biopesticides, vermicompost, sea kelp (seaweed fertilizer), protein hydrolysates, organic carbon and rock phosphate
Note:
It is advisable to have a one-week gap if soil application pesticides are to be used after application of Zn Sol B®.
Store in ambient temperature, not more than 35 degrees Celsius. Preferably store between 4 – 10-degree Celsius. Keep container closed after use. Store in a dry place.
Zn Sol B®has a shelf life of 6 months from the date of manufacturing.
Zn Sol B® composition can be customized to meet local regulatory guidelines. Zn Sol B ® is registered under the Fertilizer Control Order- Govt of India
Zn Sol B® is offered in India - as Zinc mobilizing bacteria with label claim of Starkeya novella in carrier-based powder formulation.
Zn Sol B® is also offered as Soluble Powder formulation and Soluble Liquid formulation.
