| Abstract | The study of IPM in controlling Diamondback moth (DBM) was initiated to control DBM and reduce the use of chemical insecticides in cabbage production at Kashimpur, Gazipur district, Bangladesh during December, 1998 to March, 1999. A survey with farmers and extension workers was carried out to obtain the details of the current DBM controlling practices. The effects of Bacillus thuringiensis (Bt), nimbecidine and chemical (Nogos) was ยท tested for DBM control, crop yield, influence on other pests and natural enemies during field testing. Results from the survey showed that the current practice farmers use for controlling DBM is mainly the use of chemical insecticides. Sanitation was done by farmers but it was not focused on DBM control. Removal of infested leaves was sometimes done by a few farmers. Crop rotation can diversify the DBM population. Farmers still have not used Microbial and botanical pesticides. The initial application of chemicals usually started at the seeding stage. From the study, comparison of with other three treatments, chemical insecticides, nimbecidine and control (no action) showed that Bt is an effective microbial pesticide in controlling DBM. Another botanical insecticide nimbecidine did not work on DBM, other pests and natural enemies. From the data analysis it was observed that Bt does not harm the natural enemies and does not affect other pests in the cabbage field. The marketable yield of Bt non-applied plots and applied plots were not significantly different but significantly difference with nimbecidine and control treatments means that Bt is highly effective similar to chemical insecticides. |
