ABSTRACT

The cashew (Anacardium occidentale L.) is an export oriented plantation crop. Among the various factors responsible for low yields in cashew, the insect-pests are major one. The cashew stems and root borer (CSRB) Plocaederus ferrugineus L. is one of the serious pests in cashew. The tiny grub of CSRB bores into the fresh tissue and feeds on the phloem and xylem tissues of the trunk and root with making irregular tunnels. Due to extensive tunneling the vascular tissues were damaged and plant sap movements were arrested and ultimately trees died. For management of the CSRB, an experiment was conducted using different bio-control measures including two plant products (neem oil @ 5% and neem cake) and two microbial pesticides such as Metarhizium anisopliae (Metsch) Sorkin (Deuteromycotina: Moniliales) and Beauveria bassiana (Bals.) Vuill in different time intervals and in different combinations. All the treatments were effective and superior over control in minimizing the CSRB infestation. Application of M. anisopliae spawn 250g/tree along with neem cake 500g (T4) was most effective treatment with least infested trees (7.40%) followed by application of B. bassiana spawn 250g/tree along with neem cake 500g (T5) with 11.11% infested trees.
