• Inventor-Gopal bhise
• State-Maharshtra
• Age-64 years
• Problem- growing of weeds in his farm that took space,
nutrients,sunlight and moisture reducing crop yield.
• Solution-Bhise has fixed a rod with a blade at the end, to an
assembly consisting of only the front wheel and the handle of
a bicycle. He has named the assembly as 'Krishiraja', and
claims it to be extremely efficient in removing weeds from
hard land.

very small farm plots, gardens and kitchen gardens. One can
cover 0.08 hectare in one hour.

• Inventor-green garndens.inc
• Countries such as USA,Australia etc. faced the
same problem
• To solve it they launched two tractors
that specialised in weed removing but they were
too expensive and consumed a lot of fuel
• So they came up with another solution which was
a product known as weed pharm which is An
organic food grade acid, all natural, nontoxic,
biodegradable, nonselective weed and grass killer
that’s absolutely eco friendly.
