Description

Status of Exposure of Bio-Systems to Restricted Aluminium Phosphide Pesticide in Kano State, Nigeria is a well-researched topic, it is to be used as a guide or framework for your Academic Research.

Abstract

Insect pests are one of the major organisms that are responsible for the reduction in quality, germination potential, and quantity of maize grains as well as seeds in storage. The aim of this study was to assess the types, sources of chemicals used to preserve maize in Nigeria as well as to ascertain the technical know-how of handling these chemicals among maize merchants. The study was conducted in Kano State of Nigeria. Four local government areas which are Kura, Rogo, Garun-Malan, and
Rano was selected at random from the state and from each local government area, two villages were selected at random.
Fifty respondents were chosen at random from the two villages to make a total of 200 respondents in all. Information on the most commonly used maize preservative chemicals was obtained through structured questionnaires. The result of the survey indicated that the mean age ranged between 46-49%, modal age (38-56%), respondents with no formal education (19-40%), those with primary school education, quranic education, secondary school, and tertiary education ranged between 37-42%, 0-13%, 7-16%, and 10-20% respectively. The majority of the respondents are male (77-88%). The most commonly used maize
storage pesticide was aluminum phosphide (42-52%). Lack of formal education among maize farmers/merchants is majorly responsible for the misuse of pesticides in the study areas.

INTRODUCTION

Maize grain losses in particular have been said to
contribute to food insecurity and low farm income.
The effect of post-harvest losses as one of the critical
constraints to food security among farmers across
Africa cannot be over-emphasized (Owusu, 2001;
Owusu et al., 2007). Insect pests are one of the major
organisms that are responsible for the reduction in quality,
germination potential and quantity of maize
grains/seeds in storage (Olakojo and Akinlosotu,
2004). Larger grain borers (Prostephanus truncatus),
grain weevils (Sitophilus spp.), and Angoumois grain
moth (Sitotroga cerealella) are the most important
stored cereal pests in Africa are (Phiri and Otieno,
2008; Abate et al., 2000). Between 40 and 100%
losses of agricultural produce had been reported
without chemical treatment at household levels in
Malawi (Denning et al., 2009) while about 45% of the
total production of rice and cocoa were lost without
the use of pesticides (Tijani, 2006). As a mean of
safeguarding agricultural produce from such
enormous losses the use of pesticides becomes a
necessary steps towards ensuring food security.
Synthetic pesticides have been reported to provide
effective control when used correctly. The major
chemical classes of pesticides in existence are
organochlorines, carbamates, pyrethroids, and
organophosphates (Ogah and Coker, 2012). The use
of pesticides will not only keep off the pests but also
assist to keep the quality of the produce. The use of
agrochemicals has been observed as a mainstay of
agriculture across the globe as a result of the benefits
it offers (Olabode et al., 2011). The benefits include
reduction of drudgery, timely and efficient weed
control, effective pest control, and enhancement of the
shelf life of agricultural produce. Pesticides are also
used in public health as well as in other areas for the
control of pests and disease vectors (Ogah and Coker,
2012).
