Monographella albescens is a fungal plant pathogen¹ also known as leaf scald¹ which infects rice.¹

Transmission

Conidia are transferred by water splash.²

Host resistance

Lines of rice that are resistant against M. albescens are available.² Most resistance breeding has been in field trials in countries where the disease is already widespread.² Even in "resistant" strains, however, there is some noticeable lesioning but little to no loss of yield.² The mechanism of resistance remains unknown.² There is wide variation in pathogen strain-host strain pathogenicity.²

Rice plants fed increased silicon showed increased resistance to M. albescens.¹ Surprisingly this is not - or not entirely - due to its structural role but also due to increased production of various compounds and enzymes.¹
