Characterization of a Novel Adhesin-like Gene and Design of a Real-Time PCR for Rapid, Sensitive, and Specific Detection of Spiroplasma kunkelii [PDF]

Plant Disease, 2006
Spiroplasma kunkelii, a cell wall-less bacterium, is the causal agent of corn stunt disease. The pathogen is restricted to phloem sieve cells of infected plants and is transmitted by phloem-feeding leafhoppers. Since symptoms of corn stunt disease may not appear until close to flowering time, early detection of the pathogen in disease-transmitting ...

Complete Genome Sequence of Spiroplasma kunkelii Strain CR2-3x, Causal Agent of Corn Stunt Disease in Zea mays L [PDF]

Genome Announcements, 2015
ABSTRACT Spiroplasma kunkelii causes corn stunt disease of Zea mays L. in the Americas. Here, we report the nucleotide sequence of the 1,463,926-bp circular chromosome and four plasmids of strain CR2-3x.

When Does Fungicide Use Pay Off in Maize? Evidence From Low Foliar Disease Pressure Environments in Southern Brazil

Journal of Phytopathology, Volume 174, Issue 3, May/June 2026.
ABSTRACT Foliar fungicides are widely used in maize production in southern Brazil, yet their economic justification under low disease pressure remains uncertain. We synthesised yield and economic responses to a fungicide programme using a random‐effects meta‐analytic approach based on 19 multi‐environment trials conducted across the first and second ...

Effects of Phytoplasma Infection on Aster Leafhopper (Macrosteles quadrilineatus) Settling Behavior and Development on Brassica napus

Entomologia Experimentalis et Applicata, Volume 174, Issue 2, Page 132-141, February 2026.
Aster yellows phytoplasma (AYp) infection alters host plant preference in aster leafhoppers (Macrosteles quadrilineatus), with infected vectors showing a significant preference for AYp‐infected canola (Brassica napus) early in the infection period. However, this preference fades as infection progresses. Despite early attraction, B.

Spiroplasma citri : a wide host range phytopathogen. [PDF]

, 2011
Spiroplasmas are helical motile filamentous, wall-less and culturable mollicutes. Thirty six spiroplasma species have been identified. Only S. citri, S. kunkelii and S. phoeniceum have been identified as plant pathogens.

Sustainable control of Dalbulus maidis: A field study with entomopathogenic fungi

Entomologia Experimentalis et Applicata, Volume 173, Issue 11, Page 1156-1164, November 2025.
Dalbulus maidis, a plant pathogen vector, poses a serious threat to maize production and food security. We investigated the potential synergistic effects between formulations based on entomopathogenic fungi and corn hybrids with varying resistance to maize stunt complex and Maize rayado fino virus. The combined management of M. anisopliae + B. bassiana
