Abstract

A field study that determined the arthropod population and pest damages as affected by different crop establishment in rainfed ecosystem was conducted during 2012 WS. Pest population and damages were observed from farmer's field in three rainfed rice growing areas at San Jose City, Nueva Ecija and Victoria, Tarlac. Observations were made at tillering, booting and dough stages of the rice crop. Insect pests observed were mostly GLH, BPH, and WBPH while damselfly, spiders, and Conocephalus were the natural enemies. Generally, the arthropod population and pest damage were low in all sites. The most prevalent diseases observed were sheath blight and blast. Sheath blight was higher in direct-seeded and rat damage was observed also in direct-seeded set-up only. Another field set-up will be conducted this 2013 wet season to verify the results to come up with a recommendation.
