General Instructions for Genfarm Carfentrazone 400 Herbicide:

Overview:

• Genfarm Carfentrazone 400 is an emulsifiable concentrate formulation.
• To be mixed with water and applied as per the labeled Directions for Use.

Purpose:

• Genfarm Carfentrazone 400 is a post-emergence herbicide.
• Used to improve control of certain broadleaf weeds, including marshmallow, prior to establishing fallows and winter/summer broadacre crops.
• Controls marshmallow in grass pastures, commercial, industrial, public service areas, and around agricultural buildings, yards, and other farm situations.
• Can be used alone with a suitable adjuvant for volunteer cotton seedlings, including Roundup Ready cotton.
• Used for desiccation of regrowth in cotton.

Symptoms:

• Fast-acting contact herbicide causing membrane disruption in plants.
• Rapid absorption through foliage.
• Signs of desiccation appear within hours, followed by necrosis and death.

Timing:

• Apply to small, actively growing weeds (<6 to 8 leaf stage).
• Best control achieved when weeds are exposed and not shielded by other vegetation or stubble.
• For cotton, apply if regrowth occurs after the initial defoliation program.

Mixing:

• Half-fill the spray tank with water and start agitation.
• Add any partner SC or WG herbicide if required before an EC or knockdown herbicide.
• Add the measured amount of Genfarm Carfentrazone 400, followed by the knockdown herbicide (if required).
• Add the balance of water, adjuvant, or additive recommended for use.
• Maintain good agitation until spraying is completed.
• Do not store the spray mixture overnight.

Application:

• Do not apply by aerial application except for cotton desiccation.

Ground Sprayers:

• Apply as a broadcast using a conventional boom sprayer with mechanical or bypass agitation.
• Use specified single orifice flat fan nozzles. Avoid certain nozzles.
• Calibrate equipment for correct and uniform application.
• Spray volume: 50 to 150 liters per hectare (minimum 80 L/ha for volunteer cotton).
• Ideal conditions: Moist soil, fine weather, and no rain expected within one hour.

Cotton Application:

• Use sufficient water for complete coverage (at least 100 L water per hectare).
• Use three or more nozzles per row for good coverage.

Knapsack, Pneumatic, Handgun Sprayers:

• Apply at the recommended rate in conjunction with labeled handgun rates of a knockdown herbicide.
• Spray volume: 500 to 1000 liters. Higher volumes for dense vegetation.

Aerial Application (Cotton Desiccation Only):

• Apply by fixed-wing aircraft in a minimum of 30 L/ha water. Ensure thorough coverage.

Sprayer Clean Out:
