ABSTRACT

Developing Biointensive Integrated PestManagement (BIPM) package involving bio agents and safer insecticides facilitateto achieve sustainable yield and quality and monitory benefits to farmers and sugarmills and brings out green environment. In order to find out the effect ofvarious BIPM components to sugarcane borer complex an investigation wasundertaken at Sugarcane Research Station, Melalathur during 2010-2011. Thetreatments imposed were: T1 carbofuran 3G @ 1 kg a i ha-1 at basal and 105 DAP(days after planting), T2-rynaxypyr 20 SC @ 75 g aiha-1 (sett treatment) + soildrenching at105 DAP @ 75 g a i ha-1, T3-intercropping of blackgram+ mechanicalremoval of top borer infested shoots and egg masses of internode and topborers, T4- neemcake @ 125 kg ha-1 at basal and 105 DAP, T5-release of T.chilonis@ 2.5 cc ha-1 release-1 starting from 30 to180 DAP at 15 days interval (11releases), T6-combination of T4 + T5, T7- intercropping of blackgram +Detrashing at 150, 180 and 210 DAP+ T6 and T8 untreated check. Observations onthe incidence of shoot borer were recorded on 30, 45, 60 and 90th days afterplanting and percentage of shoot borer incidence was recorded and pooledincidence were worked out. The internode borer incidence was recorded at thetime of harvest based on number of canes affected with respect to total numberof canes in a randomly selected row in each plot and percentage incidence ofinternode borer was worked out. The yield parameters like cane yield, sugar yieldand per cent CCS recorded at the time of harvest. Results clearly showed thatrynaxypyr 20 SC @ 75 g ai ha-1 recorded lowest percent damage of early shootborer followed by T7. The incidence of internode borer was the lowest in T2 whichrecorded highest cane yield of 102.50 tonnes/ha followed by T7
