Bio-inputs are special liquid formulation containing not only
the desired micro-organisms, but also special cell protectants
or substances that encourage formation of resting spore or
cysts for longer shelf life and tolerate adverse conditions.
This technology is an alternative solution to Carrier based
Bio-inputs and it is not the usual broth culture from the
fermentor for mixing with the carrier.
in commercial production dormant technology is followed, where
generally Growth suppressants, Contaminant suppreesants, fungicides,
insecticides, etc., are used for long term viability. But
these formulations is particularly not suitable for Microbial
organisms whose fast actions are required immediately for
crops. When applied in crops it takes prolonged reactivation
has adopted a new technology in liquid formulation, a process
which involves arresting of bacteria or Fungus without preservatives.
concept of Liqid formulations :
There are 4 basic concepts in Liquid formulation,
- To stabilize
the Microbial organism during production, distribution and
- To easily
deliver to the field in the most appropriate manner.
- To protect
the Microbial organism from harmful environmental factors
at the target site (Field), thereby increasing persistence.
- To enhance
activity of the organism at the target site by increasing
its activity, reproduction, contact and interaction with
the target crops.
of Microbial based Liquid Bio-inputs :
The advantages of Liquid Bio-inputs in the light of drawbacks
of Carrier-based Bio-inputs are given below :
shelf life - A shelf life of 1 to 2 years, making them more
attractive commercial proposition.
- No effect
of high temperature, as dispensed in cyst or spore forms.
fitting in the farmers' mindset - 2 ml per litre of water
was the dose advised which the farmers regularly use for
by typical fermented smell.
being in cyst or spore form, multiplication is arrested
and the same generations reach the farmers, which are tested
in the laboratory. No loss of properties due to sub-culturing.
