Abstract

Abstract:

To investigate the effects of combining herbicides and biostimulants on maize growth and weed control efficacy, a field experiment was conducted using 35% nicosulfuron·mesotrione·atrazine mixed with varying doses of biostimulants. The results showed that the standalone application of 35% nicosulfuron·mesotrione·atrazine achieved over 95% weed control efficacy. Compared with the water control, the standalone herbicide treatment significantly increased maize plant height, stem diameter, leaf area, and relative chlorophyll content (SPAD) on values 10 days after application. When the biostimulant Youcuilu was combined with 35% nicosulfuron·mesotrione·atrazine, there was no significant difference in weed control efficacy compared to the standalone herbicide treatment. However, on 10 days after spraying, the combined treatment further enhanced plant height, stem diameter, leaf area, SPAD values, and increased yield by 6.9%-11.0%. Overall, the treatment of Youcuilu 3 000 mL·hm^-2 + 35% nicosulfuron·mesotrione·atrazine 2 550 mL·hm^-2 promoted maize growth and improved yield, demonstrating potential for practical agricultural application.

Key words: herbicide, biostimulant, maize, 35% nicosulfuron·mesotrione·atrazine
