Who is considered as the 'Father of Plant Pathology'?
'पादप रोग विज्ञान का जनक' किसे माना जाता है?
EXPLANATION Heterosis, Inbreeding Depression, Combining Ability and Hybrid Seed Production

Foundational pioneers of plant pathology:

  • Heinrich Anton de Bary (1831-1888), a German mycologist, proved conclusively that Phytophthora infestans was the causal incitant of the Irish potato late blight, establishing the germ theory of plant disease. He is universally recognized as the Father of Modern Mycology and Plant Pathology.
  • P.M.A. Millardet discovered Bordeaux mixture (1885).
  • Sir Edwin John Butler is recognized as the Father of Modern Indian Plant Pathology.
  • Robert Koch formulated Koch's postulates for animal pathology.

पादप रोग विज्ञान के जनक:

  • जर्मन वैज्ञानिक एंटोन डी बारी (1831-1888) ने आलू के पछेती झुलसा रोग के कारण (फाइटोफ्थोरा इन्फेस्टैन्स) की खोज कर रोगाणु सिद्धांत सिद्ध किया। उन्हें आधुनिक कवक विज्ञान और पादप रोग विज्ञान का जनक माना जाता है।
  • मिलार्डेट ने बोर्डो मिश्रण की खोज की थी।
  • ई. जे. बटलर को भारतीय पादप रोग विज्ञान का जनक कहा जाता है।
  • अतः सही उत्तर एंटोन डी बारी है।
