Advisory on following Newpath with grain sorghum
A couple of our readers in Louisiana forwarded an advisory regarding planting grain sorghum behind Newpath herbicide. The advisory was from Alvin R Rhodes, BASF Tech Service Rep. The memo follows:
"With the growing interest in planting grain crops in 2007, your assistance would be appreciated in reminding producers to guard against possible followcrop issues. Specifically, there is some interest in rotating some 2006 rice acres to grain sorghum in 2007. As you know, there is an 18-month followcrop restriction for planting grain sorghum following an application of Newpath herbicide. Newpath was likely applied on any CLEARFIELD rice field planted in 2006. Rotation to field corn following a Newpath application is only an 8.5 month period, therefore field corn planting is not a followcrop concern."
Reader Comment (Anonymous): Based on personal experience, grain sorghum is hard to grow following rice. It emerges, then turns red and purple, and grows at half the rate of grain sorghum following cotton or soybeans. Phosphorus tie up is usually the culprit.
