Use of metaldehyde as molluscicide in milkfish ponds
METAR metaldehyde formulations were tested under laboratory and faild conditions againts brackishwater pond snails (certhium so.). Under laboratory conditions the LC50 and LC99 3 days after treatment ranged from 2 - 3.5 and 4.8 - 5.4 kg/ha, respectively. However. these levels proved inffection when applied directly under actual pond conditions. In ponds with snail populatin of about 300/m2, a higher application rate of 30 kg/ha is recommended. Application of META metaldehyde concentrations of 0 - 175 kg/ha did not affect milkfish juveniles (1 - 3g body weight) 7 days after treatment. Results suggest that META metaldehyde formulations were effective for pond snail control without detrimental effect on juvenile milkfish.
