The drug from the fungal plant diseases Quadris is produced in Switzerland by Syngenta Crop Protection Co in the form of a concentrated suspension (SC, CS) with an active substance content of 25% (250 ml / l). Packaging 6 ml and 1 l. The active principle is azoxystrobin from the class of strobilurins.

As can be seen from the formula in Fig., The preparation does not contain the active agents of traditional toxic chemicals: metal ions, sulfur, phosphorus. This makes it possible in principle to create plant protection products (CWS) that do not accumulate at all in fruits and do not affect the environment: the strobilurins in nature quite quickly completely decompose into safe components. However, substances of this class in agricultural technology are used relatively recently, and therefore the preparations on strobilurins are not devoid of features and disadvantages, and the approach to their use is needed significantly different than with traditional means. Quadries are no exception.
