    COMPARATIVE EFFICACY OF SOME BOTANICALS AND CYPERMETHRIN AGAINST COWPEA INSECT PESTS AT THREE DIFFERENT PERIODS OF SPRAYING IN A GUINEA SAVANNA ZONE OF NIGERIA
    (Department of Agronomy, Nasarawa State University Keffi, 2005-11-09) Ajayi, Folorunso A.; Mundi, A.D,; Rahman, S.A.
    A, study was carried out in 2003 and 2004 rainy seasons to study the efficacy of aqueous leaf extracts (ALE) of neem'wild basil, ecalyptus and Cypermethrin 10% EC on the insect pests causing damage to flowers and seeds of cowpea (IAR 48) in Lafta, located in the Guinea Savanna o f Nigeria. The field was laid out in a randomised complete block design and treatments consisted of one dosage rate (20%/4m2) of botanical pesticides and recommended rate of (3.5 litre/ha) of Cypermethrin 10% EC. Pesticides were applied once per day in the morning or evening and twice per day (both morning and evening) to a total of four sprays. Results showed that the use of Cypermethrin performed significantly (P<0.05) better than any of the botanicals in the two seasons in protecting flowers and seeds from insect pest infestation. Application of ALE o f neem was however, significantly better than wild basil or eucalyptus. Spraying o f pesticides twice in a day conferred a significantly higher (P<0.05) protection to flowers and seeds in the two seasons than spraying only in the morning or evening.
