農薬計算機 is a mobile application developed by fujikichi that provides a convenient solution for calculating the dilution of pesticides and liquid fertilizers. With this app, users can easily perform calculations based on the dilution ratio.

The app offers two modes: one for calculating the amount of pesticide or liquid fertilizer based on the water volume, and another for calculating the water volume based on the amount of pesticide or liquid fertilizer. Users can switch between these modes using the menu button.

While the app currently focuses on the dilution calculation, the developer has plans to implement additional features in the future, such as a mode for determining the required amount of pesticide based on the spraying area and a memo function for recording spraying details.

It's important to note that the app may have calculation or display errors, so it is recommended to double-check the results using a calculator or other tools. The developer also mentions that they cannot guarantee the app's compatibility with all devices.

Overall, 農薬計算機 provides a simple and accessible tool for farmers and those involved in pesticide and liquid fertilizer dilution, making their calculations more efficient.
