Abstract
Sustainable agricultural production is frequently related with the use of agrochemicals, particularly pesticides, which are effective in combating plant infections and pests. Herbicides, a type of pesticide used to control weeds, can have a variety of effects on the growth of beneficial microbial populations in soil. The purpose of this paper was to investigate the effects of three pesticides on the growth of Rhizobium sp. strains. In this experiment, the growth of three bacterial strains (Rhizobium (Sinorhizobium) meliloti RM1, Rhizobium trifolii RT2, and RT3) was measured in the presence of three herbicides (Lumax 537.5, Agrodimark, and Siran 40 SC), which were added after impregnation of paper discs plated on Muller Hinton Agar. In this experiment, the recommended and doubled doses of each herbicide were employed. Resistance, susceptibility - increased exposure, and susceptibility - standard dosage were assessed following inhibition zone diameter measurement. Our findings demonstrated that the diameter of the inhibitory zone varies with herbicide type, dose, and rhizobial species. The findings revealed that treatments with increasing herbicide concentrations produced a larger inhibition zone diameter. The useof Lumax 537.5 SE led to higher inhibition zone diameter compared with other herbicides. In general, Rhizobium trifolii was more sensitive to Lumax 537.5 SE and Agrodimark than Rhizobium (Sinorhizobium) meliloti. This work may have scientific and applicative relevance for plant farmers, improving their knowledge of soil microbiology and pesticide application.
