As weeds become more resistant to herbicides, plant breeders are faced with the challenge of developing new varieties that are resistant to new or older herbicides. A new rice variety being released by rice researchers at the Louisiana State University (LSU) AgCenter is showing promise.
For more than 15 years, farmers have been growing Clearfield rice varieties, a [non GMO] line that [has been breaded to be] resistant to the herbicide, Newpath….
Over time, weeds have been showing resistance to Newpath, forcing plant breeders to develop a new line.
Scientists at the LSU AgCenter H. Rouse Caffey Rice Research station are introducing the Provisia line of rice they believe will complement Clearfield lines well…
[Steve Linscombe, a rice breeder with the LSU AgCenter] expects the Provisia line to be available to growers [in 2017] on a limited basis. Having another option for fighting weeds will give farmers the opportunity to alternate between Provisia and Clearfield lines, giving them another tool to combat weeds.
Louisiana has roughly 400,000 acres of rice planted this year, a decrease of more than 8 percent. The crop suffered limited damage from Tropical Storm Cindy.
[Dustin Harrell, a rice specialist with the LSU AgCenter] added [that] the significance of damage will not be known until harvest.
