Abstract

Broccoli is the most economic important crucifer worldwide, in Guanajuato State main production problem is diamondback moth Plutella xylostella. Nowadays market includes nucleopolyhedroviruses and Bacillus thuringiensis based commercial formulations with reported efficiency against insect pests however, few data available regarding P. xylostella. Within this background, the objective of this study was the application of different formulations of PxNPV-LBIV-11 and B. thuringiensis in broccoli fields to determine its effect altogether against P. xylostella larvae. Different field locations were selected for PxNPV and B. thuringiensis application formula in Irapuato and Dolores Hidalgo municipalities; first application was PxNPV (3.5 x 1012 OBs/ha) and B. thuringiensis LBIT-287 (31,818 mg/ha) on Avenger broccoli and 47.37% mortality was observed; second application was performed in Escazú cabbage, PxNPV (5 x 1012 OBs/ha) mortality in P. xylostella larvae was registered in 92.31%; third application of a mixture of PxNPV (2.04 x 1013 OBs/ha) and B. thuringiensis LBIT-229 (666.66 g/ha) was on Centennial broccoli and 80% mortality was observed with PxNPV alone, in contrast only the 50% of mortality was registered when B. thuringiensis was sprayed in combination with the baculovirus treatment.
