Phytosanitary resistance tests
For a precise and intelligent agriculture
Diseases in fields can have a devastating impact on crops, causing significant economic losses for farmers, however, the inappropriate use of phytosanitary products as a control measure can further aggravate the situation.
The use of inappropriate phytosanitary products causes the spread of diseases and unnecessary expenses, in addition to causing damage to the environment, human health and cultural biodiversity. In addition, excessive and prolonged use of certain chemicals can generate resistance in pathogens, decreasing their effectiveness in the long term.
One of the big problems with the continuous application of the same treatments is the emergence of resistance. As shown in the image above, it only takes one or two resistant isolates to appear to pass, all of which changes the pathogen population from susceptible to resistant and causes the treatment to fail.
Each disease and each crop requires a different method of analysis. Not all pathogens have the same probability of becoming infected. develop resistance to phytosanitary treatments. In particular, there are two that cause great economic losses and that develop resistance very easily. These are powdery mildew and Botrytis cinerea (which causes grey rot).
The ZeriMar Laboratoire team is made up of doctors in biology, experts in phytopathology and phytosanitary specialists who have been working in this field for years. perform phytosanitary efficiency tests for the private and public sector, developing our own methodologies. We have developed Methodologies for the rapid analysis of the effectiveness of research phytosanitary products against Botrytis cinerea, Cercospora sp. and powdery mildew, among others.

Our long experience in the study of plant diseases and their treatment with phytosanitary products makes us aware of the mechanisms of action of compounds and the mechanisms used by pathogens to resist treatments.
At ZeriMar Laboratoire we carry out analyses of the effectiveness of phytosanitary products, evaluating different compounds and demonstrating their effectiveness in controlling pathogens and providing valuable information. In this way you will be able to know which compounds act on the pathogen and which do not, thus reducing the unnecessary use of chemicals, minimizing costs, the emergence of resistance and negative impacts on the environment.
By using our services, you will be able to make smart and accurate decisions and develop the best disease management strategies, thus promoting more sustainable and profitable precision agriculture in the long term.
If there is a pathogen or disease that is causing you problems or worries you for the next campaign, contact us.
