Abstract

Various formulations of two strains of Trichoderma harzianum (Th 37 and Th 38) were tested in sugarcane crop (CoLk 7701) during 2006-07 and 2007-08 for ascertaining its response on Colletotrichum falcatum, Pyrilla perpusilla and Epiricania melanoleuca. The results indicated that metabolites (2.5%) of Th-37 and Th-38 increased the population of Epiricania cocoons by 136.05% and 95.24%, respectively and reduced the population of Pyrilla nymphs and adults to the tune of 44.92, 29.30 % and 44.92, 36.63 % in Th 37 and Th 38 applied plots, respectively. Regarding red rot, the same treatments increased the control by 36.06 and 36.08%, respectively. Application of T. harzianum indirectly supported the build up of high population of the parasitoid E. melanoleuca for the management of the Pyrilla. Application of T. harzianum enhanced the field availability of nitrogen to the crop and consequently Pyrilla population increased which ultimately influenced the speedy multiplication of Epiricania. It is also inferred that T. harzianum does not have any harmful effect on the parasitoid.
