The 2012 RUFORUM Biennial Conference is the third in the series. The main objective of the Biennial conferences is to provide a platform for agricultural research for development stakeholders in Africa and beyond to actively exchange findings and experiences, while at the same time learning lessons towards improving performance of the agricultural sector and ultimately people’s livelihoods. The biennial conference is RUFORUM’s most comprehensive meeting for the diversity of stakeholers in agriculture. It is especially dedicated to graduate students and their supervisors, grantees in RUFORUM member universities and alumni. It is a platform for peer review, quality control, mentorship, networking and shared learning. The third Biennial Conference was attended by 657 participants.This record contains an extended abstract accepted under Integrated Crop Management
Effects of aqueous extracts of Basil, Sodom’s apple and Coriander on leafminer damage to Okra
Abstract:
An experiment was conducted at the University of Gezira
Experimental farm to evaluate the effects of 10% aqueous leaf
and fruit extracts of Basil (Ocimum basilicum L.), leaf extracts
of Sodom’s apple (Calotropis procera Ait) and fruit extract of
Coriander (Coriandrum sativum L.) on damage of okra by
the vegetable leafminer (Liriomyza spp). . The experimental
design was a completely, randomised block with 4 replicates.
The treatments consisted of spraying okra plants with 10%
aqueous extracts of basil, sodom’s apple and coriander. The
efficacy of the extracts was assessed by periodic counting of
active mines (where leafminer larvae were alive and feeding).
The results indicated that the three aqueous extracts significantly
(P<0.05) reduced the infestation level by the leafminer on okra
leaves. Sodom’s apple extract resulted in the lowest cumulative
number of active mines (106), leafminerfollowed by coriander
(124) and basil (132). The control treatment had 489 active
mines. These three plants should be promoted for the
management of leafminers on okra.
Une expérience a été menée dans la ferme expérimentale de
l’Université de Gezira pour évaluer les effets des extraits du
fruit et de la feuille à 10% de solution aqueuse de Basilic
(Ocimumbasilicum L.), des extraits de feuilles de pomme de
Sodome (CalotropisproceraAit) et l’extrait du fruit de la
coriandre (Coriandrumsativum L.) sur les dommages du
gombo par la mineuse des feuilles des légumes (Liriomyza spp.).
Le dispositif expérimental était entièrement, en blocs aléatoires
avec 4 répétitions. Les traitements ont consisté en la pulvérisation
des plantes de gombo avec d’extraits de basilic, de pommes de
Sodome et de la coriandre à 10% aqueux. L’efficacité des
extraits a été évaluée par comptage périodique de mines actives
(où des larves des mineuses sont vivantes et nourries). Les
résultats ont indiqué que les trois extraits aqueux ont réduit de
façon significative (P <0,05) le niveau d’infestation par la
mineuse des feuilles sur les feuilles de gombo. L’extrait de lapomme de Sodome a abouti au plus faible nombre cumulatif de
mines actives (106), la mineuse des feuilles suivie par la coriandre
(124) et le basilic (132). Le traitement de contrôle a eu 489
mines actives. Ces trois plantes devraient être promues pour la
gestion des mineuses sur le gombo.
