title: [Photo-degradation of plant-protecting agents].
abstract: The photo degradation of some agents of plant-protecting agents is illustrated by survey. The author proves that the photolytic degradation is a relevant process of the total degradation in many agents so that it has in an increasing manner to be taken into consideration with the ecologic-chemical assessment of plant-protecting agents. The photolysis of agents is discussed for the conditions in water, at surfaces of the ground, plants and glass at open grounds and models. The velocity of photolytic degradation of the agent mainly depends on the medium at or within which the agent exists. A correlation between stability of the photolysis and features of the structure of the chemical compound can be realized by means of the quantum efficiency.
