Abstract

Abstract:

This study aims to explore the effect of different compound herbicides in controlling annual weeds in wheat fields, providing reference for local weed control in wheat fields. Field experiments were conducted using three different concentrations of herbicides to investigate their safety for wheat and weed control effects. The results showed that the plant control effects of tested herbicides achieved 74.3%-90.2% against gramineous weeds and achieved 72.4%-96.0% against broadleaf weeds after 35 days. The plant control effect was 75.8%-89.1% and the fresh weight control effect was 80.9%-91.2% against gramineous weeds after 80 days of treatment. The plant control effect was 69.2%-92.0% and the fresh weight control effect was 74.3%-92.4% against broadleaf weeds after 80 days of treatment. Totally among the tested herbicides, 50% tribenuron-isopropyl showed the best control effect at a dosage of 2 400 g·hm^-2 against annual weeds (gramineous and broadleaf weeds) in the area, which was safe for wheat and showed the highest wheat yield.

Key words: compound herbicide, control effect, annual weeds, wheat
