Snail control using copper sulphate
Snails in rice crops can be effectively managed through crop rotations, however this con icts with the need for farmers to minimise total farm water use by using water remaining in the soil pro le from the previous crop. Chemical control is the only other option for snail control, and copper sulphate is the only chemical currently available. Although generally effective, its behaviour in the environment means its use has several drawbacks.
