Efficacy of Newer Molecules, Bioagents and Botanicals against Maydis Leaf Blight and Banded Leaf and Sheath Blight of Maize

Maize (Zea mays L.; 2N=20) is major staple food crop grown worldwide adapted to several biotic and abiotic stresses. Maydis leaf blight (MLB) and banded leaf and sheath blight (BLSB) are serious foliar fungal diseases may cause up to 40% and 100% grain yield loss, respectively. The present studies were undertaken to work out the efficacy of chemicals, botanicals and bioagents for the management...

Analysis of quantitative trait Loci for resistance to southern leaf blight in juvenile maize.

ABSTRACT A set of 192 maize recombinant inbred lines (RILs), derived from a cross between the inbred lines Mo17 and B73, were evaluated as 3-week-old seedlings in the greenhouse for resistance to southern leaf blight, caused by Cochliobolus heterostrophus race O. Six significant (LOD >3.1) quantitative trait loci (QTL) were identified for disease resistance, located on chromosomes 1, 2, 3, 6, 7...

Turcicum Leaf Blight Resistance in Maize: Field Screening of New Inbreds and Hybrids

This paper presents identification of sources of Turcicum Leaf Blight (TLB) resistance in maize. Maize is affected by more than 60 diseases, of which 16 are major ones. TLB, caused by E. turcicum, is considered a serious disease where climatic conditions are cool with high relative humidity. Severe losses in grain yield ranging from 25 to 90 per cent have been reported in India. Seventy two hyb...

REACTION OF BARLEY GENOTYPES TO Bipolaris sorokiniana

A study on response of 29 barley genotypes resistant to Bipolaris leaf blight (Bipolaris sorokiniana) was conducted to investigate the relationship of the components of resistance of 29 barley genotypes. Data on five components of resistance viz., infection frequency (number of lesions per plant), lesion size (mm), percent leaf area affected by lesion, percent necrotic area on leaf, and disease...
