Knock Out Nematode
University of Georgia nematicide trial shows
Results from a recent corn trial in Georgia comparing three nematicide fumigants and a nematicide seed treatment could have a significant impact on the corn production landscape in 2009.
Telone II soil fumigant from Dow AgroSciences demonstrated superiority in controlling nematodes in a heavily infested field. Corn treated with Telone yielded higher than the two other competing nematicides, nearly doubling the next closest treatment option in bushels per acre.
“This trial is the most dramatic we’ve seen, except maybe one,” says Dr. Bob Kemerait, University of Georgia Extension specialist. “There is a vast difference in growth, size and the uniformity of the corn. Telone is the main contributor to that difference.”
Kemerait says three factors motivated him to conduct the study: limited data on plant-parasitic nematodes’ effect in Georgia corn; an increase in corn production; and the prevailing belief that nematodes cannot cause substantial damage in corn.
Field Devastated By Sting Nematodes
An attempt to grow soybeans in the same field the previous year failed, continuing a trend in which crops were unsuccessfully grown in the field. The presence of Telone II soil fumigant changed all of that. “Telone is the difference between having a crop and not having a crop,” Kemerait says.
Corn Silks And Tassels More Uniformly
“Telone really makes the corn grow up more uniform,” White says. “It didn’t stunt the corn, and it made the corn silk and tassel more uniformly.”
Would White use Telone on his corn again?
“Oh yes,” he says. “We don’t have any choice. If we farm anything, we’re going to use Telone. It’s pretty simple; if you’ve got nematodes, you need to be using Telone.”
Additional Influences Of Fumigant Revealed In UGA Trial
“This trial showed two things,” Kemerait says. “First, it showed what nematodes can take away from a corn crop. Second, it showed what Telone, in a worst-case situation, can do to aid a crop. It did a remarkable job compared with other options in managing nematodes and improving yields.”
