Title

SHORT PAPER: TREND ANALYSIS OF PESTS AND DISEASES COMPLEX IN BT COTTON

Pages

  431-439

Abstract

 The significant reduction of bollworm infestation by the implementation of INTEGRATED PEST MANAGEMENT (IPM) inBT COTTON as a component of IPM led to reduction in bollworm infestation and increase in yield.However, these alterations have brought in many new biotic problems hitherto unknown or of little economic importance. Field survey of rainfedBT COTTON fields in Perambalur district of Tamil Nadu, India during 2008-2014 revealed that the incidence of various insect pests and plant diseases is on the rise in differentBT COTTON hybrids. In 2008-2009, it was observed that the BT COTTON was damaged by cotton mealybug (Phenacoccus solenopsis Tinsley), green mirid bug (Creontiades biseratance Distant) and root rot (Rhizoctonia solani Kuhn) which caused severe yield losses. In addition to that, other pests like papaya mealybug (Paracoccus marginatus Williams & Granara de Willink) and Alternarialeaf spot caused more damage in BT COTTON during 2009-10. Besides these pests, the mirid bug (Campyloma livida Reuter), stripped mealybug (Ferrissia virgata Ckll), tobacco streak virus, grey mildew Ramularia areola and boll rot incidence inBT COTTON were noticed in 2010-12. Apart from this pest and disease problems, theAlterrnaria leaf blight, root rot (Macrophomina phaseolinaMaubl) and Myrothecium leaf spot caused severe yield losses in BT COTTON during 2012-2014. The survey revealed that, the pests and disease problems are increasing year by year inBT COTTON which caused yield reduction and also increased the cost of cultivation. If left unchecked these pests and disease problems are capable of undoing all benefits gained due toBT COTTON in terms of increased yield and reduction in use of chemical pesticides.
