Pre-harvest Glyphosate Staging Guide for Pulses

Use this handy staging guide to determine when grain moisture is less than 30% in Pulse crops.

What to Look for

By applying pre-harvest glyphosate at 50-60% seed colour change in the least mature areas of the field, growers can be confident grain moisture will be <30% At this stage, seeds in the main stem will be:

  • Top = green, firm to roll
  • Middle = mostly brown, with some speckling
  • Bottom = completely brown/black

Chickpeas

What to Look (and Listen) For:

Plants are yellowed with mature pods. Seeds have changed colour and detached themselves from their pods; pods rattle when shaken

Recommended Harvest:

Minimum 7 days after pre-harvest glyphosate application.

Be Informed:

Chickpeas may not be accepted if treated with pre-harvest glyphosate. Check with your grain buyer before applying.


Dry Beans

What to Look (and Listen) For:

80–90% of the leaves have dropped and pod colour change (to mature colour) is 80%; upper pods are yellow and seed rattle in the lowest pods. Seeds have lost their green colour when split.

Recommended Harvest:

Minimum 7 days after pre-harvest glyphosate application.

Be Informed:

Most dry bean dealers do not accept beans treated with pre-harvest glyphosate. Check with your grain buyer before applying.


Faba Beans

What to Look For:

Leaves are drying down and stems are green to brown in colour; lower pods are dark brown/black.

Grain moisture is greater than 30%. Leaves and lower pods start to turn yellow. WAIT! It’s too early for pre-harvest glyphosate.

Lower pods are dark brown/black. Grain moisture is 30%. All plants in the field must reach this stage before applying pre-harvest glyphosate.

Most pods are dark brown/black and grain moisture is 20% or less.

Recommended Harvest:

Minimum 7 days after pre-harvest glyphosate application.

Be Informed:

Faba beans may not be accepted if treated with pre-harvest glyphosate. Check with your grain buyer before applying


Lentils

What to Look (and Listen) For:

80% of the plant is yellow to brown. Seeds from the top third of the plant are fully-formed and firm; seeds from the bottom third are hard and tan-brown; pods rattle when shaken.

Grain moisture is 40%. WAIT! It’s too early for pre-harvest glyphosate. All the normal pods on nodes 10-13 of the main branch completely fill the pod cavity and field remains green.

Grain moisture is 30%. 80% of the plant is yellow to brown. Seeds from the top third of the plant are fully formed and firm; seeds from the bottom third are hard and tan-brown; pods rattle when shaken.

*All plants in the field must reach this stage before applying pre-harvest glyphosate.

Grain moisture is 20%. 90% of the pods on the plant are tan-brown.

Recommended Harvest:

Minimum 7 days after pre-harvest glyphosate application.

Be Informed:

Lentils may not be accepted if treated with pre-harvest glyphosate. Check with your grain buyer before applying.


Peas

What to Look (and Listen) For:

Most pods (80%) are yellow/golden brown; seeds in bottom pods are detached and rattle in pod.

Recommended Harvest:

Minimum 7 days after pre-harvest glyphosate application.

Be Informed:

Peas may not be accepted if treated with pre-harvest glyphosate. Check with your grain buyer before applying.
