Strobilurin Fungicides

  • P. Parvatha Reddy


Natural strobilurins are produced by the forest mushroom fungus Strobilurus tenacellus, which grows on fallen pine cones, and secretes into the decaying wood on which they grow. The powerful fungicidal activity of this secretion prevents invasion by other fungi, so protecting the nutrient source of the original mushroom. This fungal antibiotic fights infections of the plants. It is remarkable for its fungitoxic activity. All fungi need to produce their own energy supply in order to grow and produce new spores. This supply is especially important during the early establishment phase of the disease life cycle. It is produced by a complex series of chemical processes in the mitochondria that are part of every living fungal cell.

They form part of the group of quinone outside inhibitor (QoI) fungicides and work by inhibiting mitochondrial respiration that prevents spore germination and mycelial growth in plant pathogens. Their strength was they were highly active on most cereal fungal diseases, including septoria, rusts, mildew and a host of others. They were also credited with physiological benefits, maintaining green leaf area for longer and delaying crop senescence. But they have a very specific mode of action, which made the chemistry vulnerable to resistance. Guidelines for reducing the risk of development of resistance against fungicides are discussed.
