When mixing pesticides
When applying pesticides:
Prevent the risk of agrochemicals and stock remedies being used to poison livestock, people and even to destroy crops. Losses are costly and can be avoided by efficient security.
Separate herbicides from other agrochemicals.
“Very toxic/Toxic” products should be grouped together.
Flammable products should be interspersed with non-flammable products of their own group.
