Influence of isoxaflutole on colonization of corn (Zea mays L.) roots with arbuscular mycorrhizal fungus Glomus intraradices
Stokłosa, Agnieszka | Nandanavanam, Ranganayaki | Puczel, Urszula | Upadhyaya, Mahesh K.
In a greenhouse pot culture study, corn plants were grown in sterilized soil containing mycorrhizal fungus Glomus intraradices and different concentrations of Converge Pro herbicide (19.8, 39.6, 79.2, and 158.4 micrograms a.i. isoxaflutole L-1 soil). Mycorrhizal colonization of corn roots was observed to be 10 to 20% at 6 wk (exp. I) and 50 to 60% at 8 wk (exps. II and III) of plant growth. Isoxaflutole did not inhibit mycorrhizal colonization in any of the three experiments. These results show that the use of isoxaflutole does not affect corn plants by influencing mycorrhizal colonization for up to 8 wk of growth.
