| Abstract | ||||
| Graminaceous weed; Echinochloa crus-galli is one of the most favourable hosts for rice sem borer. So, it was tested in rice field as a plant trap for decreasing the insect damage. The reduction in damage reached 49.1% and 32.4% in rice sown in recommended and late date, respectively, when the rice : weed was 12:2 rows. Rice : weed ratio more than 6 : 8 rows increased borer damage in rice fields. So this weed can be used in rice field as a tool of (IPM) system to reduce borer infestation, but to some extent. Also, eradication of this weed during winter time may reduce the borer damage in rice of the following season. This plant trap should be collected from rice field before flowering, and easily destroyed with machines, used as animal food, treated with insecticides or maintained as a sanctuary for the natural enemies. | ||||
