Bordeaux Mixture
General Introduction
“ Nutritech Bordeaux Mixture ” 20% suspension is one of the most important inorganic fungicides with contact- protective effect. This compound is registered on various plant diseases and provides long-term protection for plants. Bordeaux mixture has several mode of actions, by creating new chemical bonds in target organism, namely it breaks down proteins, disrupts the enzymes’ function, disrupts vital cell processes such as respiration, and reduces the activity of cell membranes, so eventually, it leads to the pathogen death. The combination of mentioned features lowers the resistance probability of pathogens to this mixture.
Technical Introduction

General Considerations
- It can be mixed with emulsifying oil for winter spraying, but do not mix with other pesticides and compounds
- The sprayer tank should be equipped with a suitable stirring system to prevent suspension silting.
- This fungicide should be prepared at the time of consumption; if the seal is opened, the storage time of the compound is reduced and it should be consumed in a short time.
