The golden apple snail has been reported as an important pest of paddy rice in all of these countries and the damage is clearly sufficiently serious to warrant major concern. The initial introduction is thought to have been from Argentina to Taiwan, but by 1982, the golden apple snail had been introduced from Taiwan to the Philippines and continued to China (1985), Korea (1986), Sarawak and Peninsular Malaysia, Malaysia (1987), Java and Sumatra, Indonesia (1989), Thailand (1989), Vietnam (1989) Hong Kong (1991), Laos (1992), and Cambodia (1995). Nevertheless, many snail-farming projects were abandoned and the golden apple snail escapes into irrigation ditches and the natural waterways, and subsequently it invaded the rice fields. Unfortunately, the low market value due to the unexpectedly poor consumer reception resulted in the elimination of its existence in Taiwan. The intention of its introduction in Asia in early 1980s, it has been considered for use as an aquaculture species that provide dietary high-protein supplement for local consumption and as an income earner for the rural poor. The golden apple snail is a freshwater mollusc that native from Northern Argentina and Southern Brazil. One of the main problems is the paddy field has been destroyed by many weeds and pests, such as insects, birds, rodents, and snails especially golden apple snail. However, achieving this task seems impossible due to various obstacles. Since the possibility of extending area under cultivation has practically been exhausted, the only alternative is to enhance crop productivity per hectare.
The continuously increasing population caused the increase of the volume in production of rice is an immediate requirement in Malaysia, in order to attain self-sufficiency in food. Most of the paddy in Malaysia is planted as wet paddy, while dry land paddy is very small acreage, and mostly in Sarawak and Sabah. In Malaysia, the cultivation of paddy rice have covers 204,246 ha area of land and principally planted in the eight granary areas Muda Agricultural Development Authority (96,558 ha), Kemubu Agriculture Development Authority (32,167 ha), Kerian Sungai Manik Project (27,829 ha), Northeast Selangor Project (18,482 ha), Penang Integrated Agricultural Development Project (10,305 ha), Seberang Perak (8,529 ha), Kemasin Semerak Integrated Agricultural Development Project (5,220 ha) and North Terengganu Integrated Agricultural Development Project (5,156 ha). Paddy is the staple food of more than 60% of the world population, and mainly produced and consumed in the Asian region which over 90% of the crop grown in Asia.
