| Abstract/Description: | Owing global climate change, surveillance is essential tool to detect changes in pattern of diseases in the crops. To fulfill this purpose surveys were conducted from 2013-18 in five maize growing zones of India viz., Northern hill Zone (NHZ), Northern West Plain Zone (NWPZ), Northern East Plain Zone (NEPZ), Peninsular Zone (PZ) and Central Western Zone (CWZ). The percent disease index (PDI) of maydis leaf blight (MLB) was moderate (45) to high (65) in 4 zones (NHZ, NWPZ, NEPZ and PZ) while low in CWZ (25). Though the lowest incidence of turcicum leaf blight (TLB) was reported from CWZ in 2013 but it has increased consistently. PDI of TLB was highest (46) in 2016 in NHZ whereas banded leaf and sheath blight (BLSB) appeared at higher intensity in NHZ and NWPZ. Moderate (42) infection of curvularia leaf spot (CLS) was observed in all the five zones whereas bacterial stalk rot (BSR) was restricted to NHZ and NWPZ with moderate infection (33-47). Post flowering stalk rots (Charcoal and Fusarium stalk rot) appeared at higher intensity in all the 4 zones except NEPZ. PDI of brown spot (BS) ranged from 15-47 in NHZ and CWZ. Sorghum downy mildew (SDM), polysora rust (PR) and wilt were observed with very low infection from PZ while bacterial leaf streak (BLS) and brown stripe downy mildew (BSDM) were observed in NWPZ. This study revealed that there is need to develop effective management toolsfor MLB, TLB, PFSR and BLSB as these are the most prevalent maize diseases in present scenario |
