Pulse crops can present a whole lot of peak variability in the course of the rising season, and this early on, staging a pulse crop for a herbicide utility definitely requires greater than only a drive by.
“You really have to get out in a field to get staging on peas right,” says Daniel Packer, senior model supervisor of herbicides at BASF, on this Pulse College episode. “They can be anywhere from two inches high, to six inches high, to ten inches high when it’s time to spray.”
Digging up a number of vegetation is at all times a good suggestion, as a result of to correctly stage the crop, the size nodes must be seen.
“Most of your (pea) herbicides can be sprayed anywhere from one to six nodes,” says Packer, so to correctly stage the crop, pull up a plant, take a look at the 2 scale nodes, that are normally at or simply under the floor, and then start counting any of the unfolded leaves, above these two scale nodes.

In a state of affairs the place the heartbeat crop obtained touched by frost, the crop can regrow from the size nodes, which might make staging slightly bit extra difficult.
“In a situation where you have two new shoots growing from the same seed out of those scale nodes, you’re going to count all the nodes above-ground on each of those shoots, as one,” says Packer. For instance, if there are two nodes on two new shoots which might be coming from the identical plant, that counts as 4 nodes.
Packer additionally says that if the crop obtained rained on inside the rain-fast interval, most in-crop Group 2 herbicides can take about two weeks earlier than seeing signs in weeds, so wait earlier than entering into to do a re-spray.
Lentils must be staged in the identical manner, by pulling up the plant and going previous the primary two scale nodes, then counting the nodes above for correct timing.
