This study to compare how the infection control of the disease, Pyricularia grisea, rice burnt in Sacc. in laboratory level by planning a trial of three repeat CRD at Chiang Mai University, biology laboratory. How to control contains. Plant diseases, anti-fungal chemicals include lemongrass and galangal oil oil Cabendazim this research to compare the control group during the trial with the fungus. Food Poison Technique Method in the control room temperature 30 ± 2° c. 95 percent relative humidity requirements for a period of 7 days (cm) inhibited area recorded to calculate the percentage inhibition of growth inhibiting fungal filaments.
