Field study evaluates weed infestation impact on corn health and yield, suggesting critical management needs.

To investigate the phytopathological impact of weed infestation on corn crop yield and health.
Field study conducted from 2020 to 2022 in Grozny region, Chechen Republic.
Observations made on early ripening corn hybrid Krasnodar 291 AMB.
Monitoring of weed populations and assessment of corn disease prevalence was conducted.
Corn weight increased with more weed presence, ranging from 125.0 to 2016.0 g/m2.
Incidence of bladder smut rose from 0.16% to 9.28% with increasing weed infestation.
Fusarium cob disease incidence increased from 0.13% to 7.38% as weeds increased.
Maximum weed infestation resulted in a yield loss of 39.21%.
First 30 days after emergence were identified as critical for weed impacts.

Okazova et al. (2024) studied this question.
