Acţiunea erbicidului Trifluralin asupra micromicetelor

Abstract

50 micromycete strains from NCNM were tested and cultivated on Czapek medium with 20% glucose in the presence of trifluralin in concentrations of: 50; 100 and 200 mg / l. It was found that all strains growth on all tested media regardless of the concentration of trifluralin supplemented in the agar medium. In order to better highlight the action of trifluralin on micromycetes in subsequent research, glucose was excluded from the Czapek medium and the dose of trifluralin was increased from 200 mg / l to 300 and 500 mg / l, so it was shown that out of 12 strains studied 6 no growth on glucose-free Czapek medium, and supplementation of this medium with trifluralin helps to stimulate their growth.
