ZEUS EV is a Basic Substance

Basic substances are, in general, active ingredients extracted from natural products and stabilized. These are not primarily used as plant protection products, but can be useful for plant protection. they are not potentially dangerous substances.

To be considered a basic substance, an active substance should be “food grade” and meet the requirements of WHO monographs on selected medicinal plants (Volume 1, Geneva, 1999) on Bulbus Allii Cepae. It was approved as a basic substance in accordance with the Regulation (EU) No. 2021/81 on January 27, 2021.

Allium cepa L. (onion) bulb, in addition to being a foodstuff, contains phyto-complexes that exhibit fungicidal activity. Its use is a valid solution both as a support for traditional phytosanitary treatments and in defence programs aiming at environmental sustainability and resistance management.

ZEUS EV instructions for use
