The Crop Protection Division/Department is one of the core Research Departments of the Institute. The Institute has five objectives in her mandates to research on 5 mandate crops (Cocoa, Kola, Coffee, Cashew and Tea). Crop Protection Department works directly on three objectives (ii – identification of the bioecology and methods of control of pests and diseases affecting the mandate crops; iv – integration of the mandate crops into cropping systems where each crop is grown by the farmers and v – translation of research results and improved technologies into practice among farmers and manufacturers in order to improve production and socio-economic life of the people) and partly on the remaining two mandate objectives. The Department comprises of 2 Sections: Entomology and Pathology with some other units based on professional competence of the Scientists. The Department has other members of staff like Laboratory Technologist, Agricultural Superintendent, Agricultural Field Officers that are supporting the research activities in the Department.
The Department has worked and still working on all the mandate crops with attendant results and/or proofs in enhancing the quantity and quality of production of the mandate crops as well as environment and sustainable livelihood of end users of research output (Institutional Handbook can be visited for some highlights).
Entomology Section, CRIN
Entomology Section of the Institute was established to identify and study the bioecology, morphometrics and systematics, Applied Insect survey and diagnostic studies, Insect bionomics, Insect genetics, control options and other applied aspects of insect science of the mandate crops with a view to provide environment friendly and sustainable solutions to the problems of insect pests associated with challenges of cocoa, kola, coffee, cashew and tea in Nigeria. The Section is also mandated to screen insecticides, screen sprayers and/or spraying pumps using standard protocols before the agrochemical companies or spraying pump producers are allowed to sell their products to farmers and other stakeholders dealing in CRIN mandate crops. Similarly, the Section trains farmers and other stakeholders along the value chain of the mandate crops of the Institute on Responsible Pesticide Usage (with respect to Health Hazards and Biosafety, Insecticide Metabolism, Toxicity classification and Lethal Doses Interpretations), Sprayer Calibration and Application Rate, Good Agricultural and Environmental Practices using AESA Technique and Population dynamics Indices and also Training of Industrial Trainees from Universities and Colleges of Agriculture/Polytechnics on Applied Entomology. Over the years some insecticides had been screened and approved or disapproved while some are currently under screening. Approved ones include: Actara WG, Proteus EC, Esiom EC – Cocoa farms, Actellic EC (on stored cocoa beans); Cymbush EC and Decis EC – Kola farms, Spindor Dust (on stored kolanuts). Unapproved Insecticides include: Avestrin, Pyrinex, Cocoastar, Capsida
The Section had worked extensively on bioecology of some major insect pests of the Institute’s Mandate Crops which include:
Cocoa – Sarlhbergella singularis, Bathycoelia thalassina, Distantiella theobromae (Myrid), Anomis leona, Macrotermes bellicosus, Psyllids spp, Zonocerus spp, Euphestia cautella, Corcyra cephalonica, Araecerus fasculatus, Conopomorpha cramerella,
Cola – Balanogastris kolae, Sophorhinus gbanjaensis, Ceratitis kolae, Anomis leona Macrotermes spp, Zonocerus spp etc
Coffee – Cephanoides hylas, Epicampoptera glauca, Hypothenemus hapei (Coffee berry borer) Macrotermes spp, Zonocerus variegatus, Araecerus fasculatus
Cashew – Analeptes trifasciata, Zoegraphus regalis, Pachnoda chordata, Helopeltis schoutideni Macrotermes spp, Zonocerus spp, Pseudotheraptus devastans
Tea – Aspervia armigera, Macrotermes natalensis, Zonocerus spp
In furtherance, IPM, Use of Pheromones in Insect Management, Flora-Fauna-Interactions, Use of Entomopathogenic Organisms in Insect Mgt., Use of Insect Genetic Cascades and Use of Bioactive Plant Extracts in Insect Mgt. are the focus of the Section in the recent times and future.
The Section is blessed with competent and dedicated members of staff and this includes:
8 Research Fellows, 2 Laboratory Technologists, 1 Agricultural Superintendent/Field Officer and 1 Administrative Officer.

Plant Pathology Section, CRIN
Plant Pathology Section of the Institute was established to proffer sustainable solutions to the problems of disease-causing pathogens affecting cocoa, kola, coffee, cashew and tea in Nigeria. The Section has also been saddled with the responsibility of conducting laboratory assays and field trials of fungicides produced by agro-chemical manufacturers with the aim of ascertaining their effectiveness and suitability for the control of diseases affecting CRIN mandate crops in Nigeria. Below is the list of some of the fungicides tested and certified/approved by the Section (on behalf of the Institute-CRIN) for use on Nigerian cocoa. They include: Funguran OH, Champ DP, Ridomil Gold, Copper Nordox 75 WP, Ultimax Plus, Kocide 2000, Red Force, Pergado, Carbrio Duo, Jorkemil Plus, Mackecknie Extra, Tandem, Micosat F Uno, and Orvego. Experimental trials of Problad Plus and Mackecknie Gold fungicides are still on-going.
Besides, the Section has the mandate to discourage the continuous or uncontrolled use of synthetic pesticides on CRIN mandate crops to the barest minimum via the development of ecologically friendly bio-fungicide alternatives and the training/education of farmers on Integrated Disease Management (IDM) which emphasizes on minimum use of pesticides to control crop plant diseases.
The Department is blessed with competent and dedicated members of staff. The list of staff of the Department and their profiles are shown below:
Plant Pathology Section presently has 11 Research Fellows, 3 Laboratory Technologists, 4 Agricultural Superintendents/Field Officers and 3 Administrative Officers.
