Rice field rats are an important pre-harvest pest of lowland irrigated rice farming systems in Vietnam. Farmers often apply traditional control measures too late for economic benefits to be achieved, due to the progressive inability of rice plants to compensate for damage. The use of computer simulation modelling was examined as a potential alternative approach to the management of rodents in lowland...
A field experiment was conducted to investigate the impact of simulated rat damage on grain yield in irrigated lowland rice in An Giang province, in the Mekong Delta of Vietnam. Rat damage was simulated by making a 45° cut at the base of the rice tillers about 3–5 cm above the soil surface. 0% (control), 5%, 10%, 25% and 50% of the tillers were removed at the tillering (25 days after sowing, DAS),...
