How can rice snail pests be eradicated?

How are you garden farmers and rice field farmers, on this good opportunity I want to write about the activities that I carry out very carefully, but as a beginner farmer I don't really understand and understand how expert farmers work, even though I have asked several times. people who have often farmed but I have not been able to master good farming methods, so that the results I will get can satisfy me later, in this post I only write briefly about the condition of the plants and seeds that I am waiting for while they are in the urea fertilizer watering phase .

In the picture you can see the rice field snail pest which in other areas might be used as food, but unlike us in Aceh, snails are a pest which we might give to domestic ducks, one of which is a snail eater which can produce harvested eggs by eating snails, said the farmer who has farming for a long time.

The seeds seen above are also maai 6 days old and on Thursday they must have been fertilized with urea around the seedling area and for other pests this will be continued after the seeds are in a few more days. so that the seeds are healthy and can develop well.

Some of the seeds don't grow well, do my farmer friends know why the seeds don't live well, and in those seeds there are also snail pests that I have to get rid of every time I go to the fields.
