The Golden Apple Snail entered the Philippines and has since become a pest to rice paddies across the nation. Efforts to eradicate the snail include various methods, all with varying degrees of success. This case discusses the use of a bioassay on alagaw leaves against the Golden Apple Snail mortality rate. The goal is that the crude juice from the alagaw leaves will work as effective if not more effectively than that other used practices. This case can be used as the basis for constructing a framework for students to perform and understand a bioassay on the Golden Apple Snail to evaluate its effectiveness as a botanical agent against the snail infestation.

Teaching Objectives

After reading and discussing the material, students should:

  • Perform a bioassay using crude plant extracts
  • Determine the best concentrations in eradicating the Golden Apple Snail using different crude extracts
  • Identify the key components and procedures for performing a bioassay
