Introduction

When spraying pesticides, the use of a knapsack sprayer requires consideration of biological, economic, environmental and operator aspects.

The purpose of this section is to provide test methods and technical requirements to ensure the safety of use and the protection of the environment.

The implementation of this series of standards will reduce operator harm to the lowest level, to avoid leakage of pesticides to the environment.
