| Abstract | The golden apple snail spread to Sabah in the 1990s’ and became a major pest of rice a few years later. As soon as the snail was recognized as pest, the Department of Agriculture initiated a research program and launched a control operation, which employed an integrated approach comprising of cultural, biological and chemical components to combat the new invasive mollusc. Dialogue and briefing sessions were also conducted for the farmers to transfer technologies and to receive feedbacks from the end users. In general, the snail was damaging to rice seedlings only during the early stages of growth. Older seedlings with their culms already hardened became tolerant to the pest, which the snail could not rasp. For this reason, 40 day-old seedlings were used in transplanting with the water level maintained at 5 to 7 cm deep for the first few weeks and for direct seeding, the field was drained to saturated soil moisture condition to immobilize snail activities prior to broadcasting the pre-germinated seeds. These methods were widely practiced because they were simple and cost effective. Farmers also introduced ducks for biological control of snail in their rice fields at a density of 5 to 10 ducks/ha during the off and pre-planting seasons. The most common molluscicide used was tea seed powder, which was applied at 51kg/ha under a stagnant water of 5 to 7 cm deep in areas with high pest population density exceeding 5 snails/m2. A plant known as Furcreae selloa var. marginata was introduced to the farming community for the management of snail in rice. However, the use of molluscicide has been restricted to minimize environmental pollution and to conserve the natural enemies of golden apple snail. The control operation successfully contained the pest within two years. However, it was difficult to prevent the pest from spreading as it could spread by occasional floods and by human activities as well. Thus it is essential to continue to monitor its spread in the ricegrowing districts. |
