Tomato powdery mildew
-
In a cDNA-AFLP analysis comparing transcript levels between powdery mildew (Oidium neolycopersici)- susceptible tomato cultivar Moneymaker (MM) and near isogenic lines (NILs) carrying resistance gene Ol-1 or Ol-4, a transcript-derived fragment (TDF) M11E69-195 was found to be present in NIL-Ol-1 but absent in MM and NIL-Ol-4.

The development of CRISPR/Cas9 technology has facilitated targeted mutagenesis in an efficient and precise way. Previously, RNAi silencing of the susceptibility (S) gene Powdery Mildew Resistance 4 (PMR4) in tomato has been shown to enhance resistance against the powdery mildew pathogen Oidium neolycopersici (On).

Powdery mildew caused by Oidium neolycopersici L. Kiss is one of the most important diseases of tomato under polyhouse conditions. During 2014-15, polyhouses of Kangra district (H.P., India) were surveyed and the disease severity was observed between 5.0 to 89.5 per cent affecting both quality and quantity of the harvest. Fourteen hybrids/cultivars of tomato were screened under p house conditions during 2014-15 cropping season, but all were found either susceptible or weakly resistant against powdery mildew.

Tomato crop is attacked by several pathogens during its cropping season. The present study was undertaken to mitigate the disease incidence using Taqat 75% WP during the year 2016-17 and 2017-18. Assessment of the disease severity was done by standard scoring methods and expressed as Per cent Disease Index (PDI). For phytotoxicity of Taqat 75%WP at X dose 750g/ha, 2X dose 1500g/ha and 4X doses 3000g/ha along with the standard check treatments.
