Rice (Oryza sativa) farming is a key economic activity in Guyana that has been progressively increasing over the years in terms of production and export. However, yields are often reduced by pest attacks during different stages of development of the rice plant. Additionally, the desired outcome of controlling pests in an environmentally-friendly manner is not easily achieved. This study investigated the effectiveness of four plant leaf extracts at different concentrations against the golden apple snail (Pomacea sp.). Mortality rates over a four-day period were compared with those obtained for traditional chemical control. Two of the four extracts were found to be as effective as the chemical control and are therefore recommended for future consideration as alternative pest control.
