Questionnaire:

• Area under rice production (ha and %): seasons and rice culture (transplanted and direct-seeded)

• Extent of damage by golden apple snail (ha)

• List of various methods adopted by rice farmers

• List of pesticides used to control golden apple snail (most popular to least preferred)

Questionnaire:

• Farmers’ criteria for the choice of a chemical:

• Efficacy
• Immediate kill
• Cost
• Ease of application
• Any other reasons (Availability, biodegradable etc.).

• Utilization of golden apple snail by rice farmers

• Liquid bio-compost
• fertilizer/ Bio-control of weeds in rice fields
• Farm animal feed
• Any other use (baits for rice bugs/rat baits/ fish baits)
• Food

Current Studies Done on GAS

Common Difficulties/ Constraints in GAS Management

• Taxonomic confusion of Pomacea spp. complex need to be resolved by molecular approaches.

• The information exchange on GAS needs to be strengthened on applesnail.net internet website through cooperative efforts.

• Timely community actions are rarely practiced to reduce GAS build-up. Thus there is a need to demonstrate the integrated approach to GAS management.

• Lack of viable technologies to manage GAS in flood-prone areas and direct-seeded rice.

• Very few information on the effect of botanical molluscicides on non-target organisms.

• Choice of non-specific pesticides still preferred by farmers because of immediate kill, followed by ease of application then cost and last efficacy.
