CHAPTER I
INTRODUCTION
Background of the Study Farming has been the main source of income of our country for years. However agricultural production was never as easy as ABC. Farmers and agriculturists tend to go through real hard work and toil in assuring crop yield because of pests which harm crops. One perfect example of these pests are the mollusks from the Ampullariidae family which in vernacular are usually called golden kuhol (golden apple snails). In the 1980s, Golden Apple Snails (Pomacea canaliculata) were introduced in Taiwan to start an escargot industry. It was thought that such food culture could provide valuable proteins for farmers, who primarily live on a rice diet. However, the snails did not become a culinary success. Instead of becoming a valuable food source, the introduced snails escaped and became a serious threat to rice production and the native ecosystems. During the 1980s the introduced snails rapidly spread to many countries including the Philippines. In order to minimize and altogether optimistically stop the dreadful reproduction of golden apple snails, the use of molluscicides and killing medicines must be done. This study was conducted to evaluate the molluscicidal effect of Neem Leaf (Azadirachta Indica) ethanolic extract against Golden Apple Snails (Pomacea canaliculata).
Objectives of the Study Generally, this study will assess the effectiveness of Neem Leaf (Azadirachta indica) ethanolic extract against golden apple snails. Specifically, this investigation will seek answers from the following question: * Is there a significant difference
