A Field trial was conducted at
the Eastern farm of Michael Okpara University of
Agriculture, Umudike, during the 2012 farming season to
assess the potentials of some organic soil amendments and
some botanicals as foliar sprays in the control of some
common bacterial diseases associated with munbean (Vigna
L.) which include bacterial blight, halo blight,
leaf spot and bacterial wilt. The soil organic amendments
employed as control measure included leaves of
Azadirachta indica
, Delonix regia, poultry
droppings and kitchen ash while the plant extracts that
served as foliar sprays in control of these bacterial
diseases were: neem seed (A. indica), ginger stem (Zingiber
) and bitter kola seed (Garcinia kola),
water was used as a control while streptomycin sulphate
served as a standard check.  A. indica
and D. regia leaves were first allowed to decompose
before application as organic amendments.  All the
experiment was in a randomized complete block design (RCBD)
and replicated three times. Results obtained showed that
organic amendments sourced from kitchen ash improved growth
of mungbean, sustained total pod yield and suppressed
disease incidence and severity. Foliar spray trials results
showed that A. indica was the best in enhancing
growth, yield (seed weight)
and most effective in reducing disease incidence and disease
severity more than other plant extracts.

Keywords: Organic
amendment, plant extracts, botanicals, streptomycin sulphate.
