“…In previous work benomyl + lindane (Oladiran, 1980), benomyl + decis (Oladiran and Oso, 1985) and benomyl + monocrotophos (Olowe et a/., 1987) have been found to increase grain yields above all other treatments as well as controlling fungal disease incidence and pod borer damage to the minimum. Although Calixin, captafol and metiram were not as effective as benomyl, their combination with insecticides also reduced disease incidence, pod borer damage as well as increased grain yield, over and above when the pesticides were employed singly.…”

Fungicides which included benomyl (methyl-1-butylcarboxyl benzimidazol-2-2 ylcarbamate), Calixin M (N-tridicyl-2-6-dimethyl-morphine), captafol (3a,4,7,7a-tetrahydro-N-N)1,1,2,2-tetrachloroethanesulphenyl phthalimide) and metiram (zincactivated polyethylene thiuram disulphide); and monocrotophos (3-hydroxy-N-methyl c/s-crotonamide dimenthyl phosphate) and permethrin (3-phenoxybenzol (I) cis,trans-3-2,2-dichlorovinyl)-2,2-dimethyl) Insecticides were tested singly and in combinations to control brown blotch and pod borer infestations due to Maruca testulalis on cowpea. Benomyl in combination with either monocrotophos or permethrin as foliar spray, controlled brown blotch and pod borer infestation best. The fungicides and insecticides mixture also gave significantly higher grain yields than when fungicide and insecticide were applied singly as foliar spray (P < 0.01). Different rates of benomyl were also tested to determine the most effective and economic rate of application. Benomyl, at 1.0 kg a.i. ha -1 tank-mixed with 0.08 kg a.i. ha -1 of permethrin reduced brown blotch incidence and pod borer infestation to less than 10%. The highest net revenue of ??1057 was realized when the mixture was applied, while a deficit of expenditure could result when benomyl was applied singly.

“…This seed-borne disease can lead to almost 60% seedling mortality and can survive on crop residues [27]. Therefore, the use of healthy seeds and resistant varieties is the best option to control the disease [48] . On the other hand, cowpea anthracnose caused by Colletotrichum lindemuthianum (Sacc.…”

Cowpea, Vigna unguiculata (L.) Walp, is among the most important grain legumes in Africa. Its nutritional value and biological nitrogen fixation (BNF) potential coupled with a high plasticity to environmental conditions places this legume in a unique position in Sub-Saharan Africa (SSA) in the context of food and nutritional security. However, cowpea yield and BNF contribution to agricultural systems in this sub-continent is far behind the average global values. The inability to run effective breeding programs to timely generate and deliver high yielding, nutritious and climate smart cowpea varieties, coupled with poor crop husbandry practices has been in the forefront of the current situation. In this chapter, the main constrains and opportunities to establish and run successful and effective cowpea production and breading programs in SSA are discussed. The discussion is built around the argument that SSA can benefit from its rich collection of landraces, as well as from high-throughput methodologies to assist the screening and the development of adapted, high yielding and nutritious varieties.
