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.
