Sprayer and Interrow Spraying Management

A lack of knowledge and skills among foremen in applying chemical weed-control methods can cause significant losses. This not only prevents work targets from being achieved but also results in waste of materials and labor.

In addition, many foremen do not yet understand how to determine chemical requirements per spray area per hectare, resulting in low spraying effectiveness. Therefore, proper knowledge and skills development for spraying foremen is essential to minimize potential losses and ensure optimal work results.
