Crop-protection products represent an indispensable component for a secure supply of food for mankind, both for quality and quantity. Because their use implies a significant interaction with nature and the environment, there are high requirements imposed by authorities. Crop-protection products are provided in a formulated form, typically designed to allow the user and farmer to apply them in a way that is typical for the regional crop situation and with the specific equipment. The user must rely on optimal product performance, thus the manufacturer must provide reproducible properties, be it for the active ingredient or for the formulation. This includes both biological and physical properties. Although there is a general state-of-the-art among the formulation peers, each new product represents a new challenge. This article shows the need for various decisions. Applying them will lead to an optimized product that includes the current state-of-the-art and also considers future foreseeable requirements.

Modern types of formulations are suspoemulsions (SE) and suspension concentrates (SC), water-dispersible granule (WG) exhibit obvious advantages too. The decision for one or the other formulation type is a consequence of a technological and an economical evaluation. The specific requirements of the respective users have to be taken into account too. In various examples, the benefits and the detriments of different formulation types and the necessary ingredients are described. Crop-protection products are end-user products that are applied at varying times. Therefore, storage and packaging need also to be strongly considered during their development.

In the last few decades the understanding of the impact of agrochemicals on nature and the environment and thus on the consumer have grown significantly. Furthermore, the knowledge about means for a secure and both a qualitatively and quantitatively augmented food production has increased. This, together with the consequent adjustment to the high technical application standards, has led to the generally accepted opinion that crop-protection products can be considered as one of the most thoroughly investigated man-made chemicals.
