What mode of action does Pristine Fungicide utilize?

Pristine Fungicide utilizes a combination of modes of action from Group 7 and Group 11, which is significant because these groups represent different chemical classes that provide distinct mechanisms for controlling fungal pathogens.

Group 7 includes the succinate dehydrogenase inhibitors (SDHIs), which affect the electron transport chain within the mitochondria of fungal cells, leading to an interruption in energy production and ultimately causing the failure of the pathogen. This action is particularly effective against a variety of important fungal diseases.

Group 11 comprises the strobilurins, which function by inhibiting mitochondrial respiration and activating the plant's defense mechanisms. This leads to not just control of the fungus but also enhancement of the plant's innate immune response, providing a dual benefit in disease management.

Using a fungicide that combines both groups effectively broadens the spectrum of activity against different pathogens and reduces the likelihood of resistance development, making it a powerful tool in integrated disease management strategies. This combination maximizes efficacy and helps ensure that the product remains effective over time by targeting multiple pathways within fungal cells.
