There are several methods for controlling snails in agricultural settings, including cultural, mechanical, and chemical control. Here are some possible solutions, with sources:
Cultural Control: One way to reduce snail populations is to modify the agricultural practices to create a less favorable environment for snails. For example:
Regularly remove debris and litter from the fields, as snails are attracted to moist and shaded areas.
Avoid overwatering the fields, as snails thrive in moist environments.
Avoid planting crops in low-lying areas, where moisture tends to accumulate.

Mechanical Control: This involves physically removing snails from the fields. Some methods include:
Handpicking: This is the simplest method of snail control, but it is labor-intensive and may not be practical for large fields.
Barriers: You can create barriers around your crops using materials such as copper or sharp sand, which snails find difficult to cross.
Traps: You can set up traps in the fields using materials such as beer, yeast, or molasses, which snails are attracted to.

Chemical Control: This involves the use of pesticides to kill snails. However, it is important to note that some pesticides may have negative effects on the environment, such as harming beneficial insects or contaminating soil and water. Before using any pesticide, be sure to read the label carefully and follow all safety precautions.

It's important to note that each of these methods has its own pros and cons, and the best approach may depend on the specific situation. Additionally, it's always a good idea to consult with a local agriculture expert or extension service for advice on managing snails in your area.
