Crop
Staging
Legumes: Alfalfa, bird’s-foot trefoil, red and
white clover (for seed production only)
Prior to seed harvest. To prevent seed pods from shattering and subsequent loss of
seed, the interval between spraying and harvest should not exceed 7 days.
Note: Do not use Reglone on forage legumes that have been treated with a residual
herbicide in the past 12 months.
Lentils
Apply at the time swathing would normally commence. This is when the lower-most
pods are yellow-brown and seeds rattle.
Mustard (condiment type)
Spray when the crop is at the 75% seed turn brown stage.
Peas (field and dry)
Apply when bottom pods of the majority of the plants are ripe and dry with the seeds
detached from the pods. Seeds in less mature pods will split when squeezed.
Potato - vine kill
Apply at least 2 weeks before harvest. Do not apply Reglone during drought periods,
especially when soil is so dry that plant leaves wilt during the day. After such
conditions wait at least 3 days after soil has been moistened by rain or irrigation.
Sunflower
When the seeds reach maturity (20 - 50% moisture in the seed and hull). Combine
15 - 20
days after spraying.

This product can cause shattering losses in canola. It should only be used on Argentine canola to assist in the harvest of a severely lodged crop.

Add Agral 90 or Ag-Surf at the rate of 1 L/1,000 L of spray solution.
Application Information
How to apply: Apply with ground equipment or by air.
Water volume: See above table.
Application Tips
Muddy water will reduce effectiveness. Applications made on cloudy days or just prior to or during periods of
darkness will increase effectiveness. Immature weeds may require higher application rates to increase effectiveness.
How it Works
Reglone is a contact type herbicide; therefore, thorough spray coverage is essential. Absorbed by all leaf and stem
surfaces, non-systemic and interferes with photosynthesis.
Expected Results
Weeds
:
Fast and virtually complete top kill of annual weeds. Yellowing starts within a few hours of application.
Desiccation of the plant will continue rapidly till death.
Crops
:
Leaf kill will occur within a few days of application. Stem dry-down will take longer depending on the crop;
however, harvesting should normally commence within 7 - 14 days. Crop losses can occur due to pod drop and pod
