A sequential sampling strategy for the control of shoot borer<i>(Dichocrocis punctiferalis</i>Guen.) in ginger<i>(Zingiber officinale</i>Rosc.) in India

Abstract

Abstract The level of infestation by the shoot borer (Dichocrocis punctiferalis Guen.) that results in a significant reduction in yield of ginger rhizomes has been evaluated; these levels are 60, 45 and 50% of pseudostems damaged per plant during August, September and October respectively. The Economic injury Level has also been worked out and a sequential sampling scheme developed for monitoring the level of pest infestation in the field as a guide for undertaking control measures against the pest.
