Abstract: REYES, ALYSSA MARI A. and SANGALANG, HERSEL DANNA E. Laboratory Screening of Botanicals Against Disease-Causing Microorganisms in Dragon Fruit. A Research Study (General Science Curriculum) Science High School, College of Education, Cavite State University, Indang, Cavite. April 2011. Adviser: Dr. Adelaida E. Sangalang. Laboratory screening of 10 botanical plants against two fungi, namely: Fusarium sporotrichioides and Colletotrichum gloeosporioides, and two bacteria, namely; Enterobacter cloacae and Serratia marcescens was conducted using Inhibition Zone Technique. Chives (Allium schonoeprasum), garlic (Allium sativum), lemon balm (Melissa officinalis), lemongrass (Cymbopogon citratus), mugwort (Artemisia vulgaris), oregano (Coleus amboinicus), parsley (Petroselinum crispum), rosemary (Rosmarinus officinalis), tarragon (Artemisia dracunculus), and thyme (Thymus vulgaris) were evaluated. Commercial fungicide, bactericide and distilled water served as controls. Results showed that botanical extracts contain fungicidal and bactericidal properties that inhibited the growth in vitro of the test pathogens. Lemongrass and parsley were the most effective against Fusarium sp. while garlic and mugwort were the most effective against Colletotrichum sp. Lemongrass and garlic were the most effective against Enterobacter sp. and Serratia sp., respectively. The above botanicals can control the diseases caused by the respective microoorganism, therefore, could possibly be used as an alternative for both fungicide and bactericide. The mechanism of action of a particular botanical seems to be specific to a particular organism. Thus, it is suggested to use the botanicals to a specific disease and corresponding causal organism.
