Crop protection agents have to overcome numerous obstacles en route to their actual target: some leaves are covered with rough, waxy crystals from which sprays simply rebound. Others have ultrafine hairs on their surface that represent an insurmountable barrier for many an active ingredient to combat harmful fungi, plants or insects.

The right formulation is crucial
Formulation technicians at Bayer CropScience utilize sophisticated substance mixtures to ensure that fungicides, herbicides and insecticides get to their site of action faster and more directly. Their goal is to protect as many plants as possible at the same time with as little active ingredient as possible. To find out how scientists prepare ultrafine spray mist droplets to protect all of the leaves of a one-hectare cereal field with just a few grams of substance, for example, read here.
