The herbicidal activity of pre-emergence herbicide cinmethylin and its potential risks on soil ecology: pH, enzyme activities and bacterial community.

ABSTRACT:

Background

The herbicide cinmethylin, which was originally registered for use in rice fields, has the potential to control grass weeds in wheat fields before the emergence of wheat. However, its herbicidal activity against various troublesome grass weeds that infest wheat fields in China and its relationships with soil pH, soil enzymes and soil bacteria are not well known. Here, the effects of applying cinmethylin on the soil surface were tested on six grass weeds, and its impacts on soil characteristics, including the soil pH, soil enzymes and bacterial community, were evaluated.

Results

Alopecurus aequalis, A. japonicus and A. myosuroides were highly sensitive to cinmethylin, with GR₅₀ values of 78.77, 61.49 and 119.67 g a.i. ha^- 1, respectively. The
