IPM teaser

                                 Introduction

         Rice, Oryza sativa, is an annual crop from the family Graminae. It is the staple food here in the Philippines. Proper care in planting rice as well as preventing pests and diseases from halting their growth thus should be employed. This presentation will discuss the Integrated Pest Management on rice plant.

                                   About IPM

         Integrated Pest Management (IPM), is a program in which cultural, biological, mechanical, physical, etc. controls are compiled and employed to achieve pest management at eco-friendly state. This is prophylactic, meaning it emphasizes prevention rather than cure.

     •Rice Blast

         Rice blast (Pyricularia grisea) is a fungus that feeds on the rice plant, causing severe damage usually during the seedling stage. It attacks different parts of the plant: the collar, which can ultimately kill the entire leaf blade.

•Bacterial Blight

      Bacterial blight is caused by Xanthomonas oryzaepv. oryzae (Xoo) and affects the rice plant at the seedling stage where infected leaves turn grayish green and roll up. As the disease progresses, leaves turn yellow to straw-colored and wilt, leading whole seedlings to dry up and die.

•Sheath Blight

      Sheath blight is a fungal disease caused by Rhizoctonia solani. Symptoms are usually observed from tillering to milk stage in a rice crop. It occurs throughout the rice growing areas in temperate, subtropical, and tropical countries. Rice sheath blight is found in all rice production areas, and is decreasing rice production especially in intensified production systems.

•Physical Control

-Drying of grains

-Barriers (covers)

-Fire (on dead plant remains)

-Traps (rodents)

•Resistant Varieties

• Deep Rooting -- dubbed DRO1 -- was spliced into a cultivar called IR64, a paddy rice plant that is grown around Asia.

•New Rice Blast Resistance Gene, Pid3.
