Title: Effect of application of different concentrations and appropriate schedules of aqueous garlic (<i>Allium sativum</i>L.) bulb extracts against<i>Maruca vitrata</i>and<i>Clavigralla tomentosicollis</i>on cowpea,<i>Vigna unguiculata</i>(L.) Walp
Abstract: Abstract Three concentrations (5, 10 and 20% w/v) and spraying schedules (2×, 4× and 6× weekly applications) of garlic, Allium sativum L. bulb extracts were assayed for efficacy against Maruca vitrata Fab. and Clavigralla tomentosicollis Stal. on cowpea under rain fed conditions in two seasons. The results showed that application of aqueous garlic bulb extracts at all the treatment levels significantly (p < 0.05) reduced the populations of the target pests compared with the untreated check. Application of 10 and 20% garlic bulb extracts with 4 or 6 weekly applications gave better control of these pests, protected the pods from damage and increased grain yields on treated cowpea compared with 5% extract at all three application schedules and were comparable to the synthetic insecticide treatment. This material could play a role in the integrated management of M. vitrata and C. tomentosicollis on cowpea fields managed by limited resource farmers in developing countries. The plant material is readily available, cheap, safe, non phytotoxic and technologically simple to use.
