Abstract

This study investigated the effects of elevated temperature and carbon dioxide (CO₂) on disease incidence, severity, and yield impacts in wheat (Triticum aestivum), cabbage (Brassica oleracea), and tomato (Solanum lycopersicum) under open-field and nethouse conditions. The pathogens evaluated included Rhizoctonia solani, Sclerotium rolfsii, Bipolaris sorokiniana, Alternaria brassicae, and Fusarium oxysporum f. sp. lycopersici. During the experimental period, maximum and minimum temperatures reached 39.3 °C and 11 °C in nethouse conditions compared with 37.5 °C and 9 °C in the open field, while CO₂ concentration was 388–395 ppm in the nethouse and 385 ppm in ambient air. Elevated CO₂ and temperature consistently increased disease incidence and severity. In wheat, sclerotium wilt showed the highest incidence (55.6%); in cabbage, both sclerotium wilt and Alternaria blight reached 100%; and in tomato, sclerotium wilt also caused 100% incidence. These infections were associated with significant yield reductions across all crops. To our knowledge, this is the first report from Bangladesh quantifying crop disease yield interactions under elevated temperature and CO₂, underscoring the vulnerability of key crops to climate change and the urgent need for adaptive management strategies.

Abstract

Wheat (Triticum aestivum L.), a vital cereal, faces significant challenges from common root rot and spot blotch diseases caused by Bipolaris sorokiniana. This study aimed to explore the potential of plant growth promoting rhizobacteria (PGPR) to enhance wheat growth, reduce fertilizer input, and combat Bipolaris diseases. Two PGPR isolates, selected for their superior antagonistic properties, were identified as Stenotrophomonas koreensis RB11 and Bacillus amyloliquefaciens RB12. These PGPR strains displayed multiple plant growth promoting and biocontrol attributes, including phosphate solubilization, indole-3-acetic acid production, nitrogen fixation and antagonism against B. sorokiniana and other fungi. Wheat seed priming with the PGPR significantly improved germination, plant growth, nutrient content and biomass carbon accumulation in the rhizosphere soil. Importantly, the application of RB11 and RB12 allowed for a 25% and 50% reduction in nitrogen fertilizer usage, respectively, without compromising the yield. RB11 and RB12 also demonstrated potent inhibitory effects on B. sorokiniana conidial germination and significantly controlled common root rot and spot blotch in wheat, similar to those observed with the fungicide Protaf 250EC. Overall, this study underscores the multifaceted roles of S. koreensis RB11 and B. amyloliquefaciens RB12 in promoting wheat growth, reducing fertilizer inputs and effectively suppressing wheat pathogens. These findings contribute to the development of PGPR-based strategies for sustainable crop production and disease control.
