Strobilurins- A New Generation fungicide

E-mail Print PDF
Presented by Dr. MP Srivastava (Complete presentation on Strobilurins, available upon request)

Strobilurins are a group of chemical compounds used in agriculture as fungicides. They are part of the larger group of QoI inhibitors, which act to inhibit the respiratory chain at the level of Complex III.

Some common Strobilurins are azoxystrobin, kresoxim-methyl, picoxystrobin, fluoxastrobin, oryzastrobin, dimoxystrobin, pyraclostrobin and trifloxystrobin.

Strobilurins represented a major development in fungus-based fungicides. They were extracted from the fungus Strobilurus tenacellus. They have a suppressive effect on other fungi, reducing competition for nutrients; they inhibit electron transfer in mitochondria, disrupting energy metabolism and preventing growth of the target fungi.

Strobies are miracle fungicides ever developed With Novel MOA & mobility that qualifies them as Unique New Generation Fungicides controlling Pathogen from diverse class

  • Let GOI & CIB permit import/ manufacture/ formulation of QoI or Strobilurins; consider modification of labels
  • Don’t get scared of resistance –Follow FRAC guidelines religiously and Relax

Discovery of Strobilurins

  • Source of maiden fungicide: Strobilurus tenacellus
  • Anke & Steglich (1977) identified strobilurin A – Antifungal antibiotic, but photolabile in nature
  • Chemists modified to restore stability
  • First synthetic with +UV stability in 1986 in cooperation with BASF
  • 1992 ICI developed Azoxystrobin; and BASF Kresoxim-methyl
  • 1996- Commercialization

Dismayed at the growing concrete jungle in Gurgaon and mindful of horrors of global warming, Dr. Srivastava has since started a movement of sorts by planting saplings of Peepal and Neem in the Millenium City. His group is called APPAN (Awareness Promotion for Peepal and Neem).
