Abstract

Background and aims

Imazethapyr (IM) is a chiral herbicide with two enantiomers, with a much stronger herbicidal effect of R-IM than S-IM. Pesticide residues are a common problem, and multi-generation cultivation method can reveal the consequences of long-term pesticide residues.

Methods

This study verified the effects of R-IM on the growth of Arabidopsis thaliana and rhizosphere microorganisms by treating A. thaliana with different concentrations of R-IM successively passaging experimental rhizospheres for three generations, and measured the changes of A. thaliana rhizosphere microbes.

Results

The growth of A. thaliana treated with R-IM (0.5 g/ha and 1.5 g/ha) was significantly inhibited especially after successive generations of culture. At the same time, R-IM treatment decreased chlorophyll and chlorophyll parameters to inhibit the photosynthetic efficiency, and it also reshaped the rhizosphere bacterial community structure of A. thaliana. This bio-effect was transmitted to the next generation of plants along with the soil microbiota.

Conclusions

The treatment of A. thaliana by R-IM in multi-generation culture resulted in an increasingly obvious growth inhibitory effect, the higher concentration of R-IM inhibited A. thaliana more strongly, and changed the abundance of rhizosphere microbes. With the cultivation of generations, the influence of pesticide residues on plants also became significant.
