EFFECT OF TRASH MULCHING AND TRICHOGRAMMA CHILONIS (ISHIl) ON SUGARCANE BORERS INFESTATION

Abstract

These studies were conducted at farmer's field in Faisalabad during 2002 and 2003 to find out an effective and economical IPM measure against sugarcane borers. Layout system was RCBD with three replications. The data revealed that trash mulching between rows+ release of egg parasite Trichogramma chilonis @ 20000 eggs/acre effectively controlled sugarcane borers with minimum borers infestation {5.00% in 2002 and 4.33% in 2003} followed by the plots where only egg parasites were released (8.75% in 2002 and 6.40% in 2003) with 18.33 and 26.65 percent parasitism. Check showed maximum borer infestation (11.33% in 2002 and 12.65% in 2003) with minimum parasitism {0.42 and 0.33%).
