Rajamallu is a farmer and studied up to seventh class. He
has observed that by avoiding chemical pesticides and opting
for herbal pesticides, the farmers can save money and reduce
harm to the crops and the environment.
He found that the fruits of ‘vishamusti’ tree are poisonous
and used it as herbicide very effectively. Utmost case has
to be taken while preparing the herbal solution. Children
have to be kept away. Only 5kg of these fruits are
sufficient far spraying an acre of cotton crop. Sustainable,
cheap and locally available herbicide needs to be encouraged
and the innovator rewarded suitably.
