Abstract

Effectiveness of powdered rock lime for giant earthworm control in infested rice paddies was examined in three (3) municipalities of the province from July 2008 to February 2009. 

The study used 3 trials at different dilution rates of 100, 200 and 300 grams powdered rock in 8 and 12 liters of water.

Results showed that dilution rates of 200 and 300 g of powdered rock lime killed the earthworms faster than 100 g dilution rate. 

The shortest time the earthworms died was at dilution rate of 300 grams with an average of 8.55 minutes followed by 200 g with an average of 9.44 minutes but with no significant difference. At the lowest dilution rate of 100 grams, earthworms died the longest at an average time of 13.11 minutes. In all the dilution rates used, giant earthworms shrink rapidly except the head, some giant earthworms bled and were cut into two. 

Keywords: giant earthworms, powdered rock lime.
