Roundup Transorb HC

Where possible, rotate the use of Roundup Transorb HC Liquid Herbicide or other Group 9 herbicides within a growing season (sequence) or among growing seasons with different herbicide groups that control the same weeds in a field.

Application rates for Roundup brand agricultural herbicides

Application Guidelines and Timing, Pre-harvest Application

Apply 7-14 days before harvest to ensure best weed control.

Water Volumes

For control of perennial weeds: apply Roundup Transorb HC in 20 to 40 L/ac. of clean water as a broadcast spray, using no more than 275 kPa pressure.

For control of annual weeds: apply Roundup Transorb HC in 20 to 40 L/ac. of clean water as a broadcast spray (except as otherwise stated on the label), using no more than 275 kPa pressure.

Rainfastness

Rainfast 1 hour after application

Tank Mixing Procedure

• Fill spray tank three-quarters full of water
• Start agitation and run for the entire mixing and spraying operation
• Add required amount of the tank mix partner
• Flush herbicide loading tank and herbicide containers with water
• If using a herbicide loading system, ensure that the loading tank and lines to the pump are empty and flushed out with water before adding tank mix partner
• Add required amount of Roundup Transorb HC Liquid Harbicide
• Flush herbicide loading tank and herbicide containers with water
• If using a herbicide loading system, ensure that the loading tank and lines to the pump are flushed with water and empty before starting spray operation
• Always start and end the mixing and spraying operation with a clean system

*When 50% of the plants in the field have more than one flower.

• Ensure the crop has not advanced beyond the recommended growth stage for all applications.
• Repeat applications may be required if a second flush of weeds germinates prior to canopy closure.
• Maximum 1.33 L/ac. is allowed for the post emergence use.

For resistance management, Roundup Transorb HC Liquid Herbicide is a Group 9 herbicide. Any weed population may contain or develop plants naturally resistant to Roundup Transorb HC Liquid Herbicide and other Group 9 herbicides. The resistant biotypes may dominate the weed population if these herbicides are used repeatedly in the same field. Other resistance mechanisms that are not linked to site of action, but specific for individual chemicals, such as enhanced metabolism, may also exist. Appropriate resistance management strategies should be followed.

Mix Groups

Use tank mixtures with herbicides from a different Group when such use is permitted. To delay resistance, the less resistance-prone partner should control the target weed(s) as effectively as the more resistance-prone partner.

Herbicide use should be based on an integrated weed management program that includes scouting, historical information related to herbicide use and crop rotation, tillage (or other mechanical control methods), cultural (for example, higher crop seeding rates; precision fertilizer application method and timing that favors crop and not weeds), biological (weed-competitive crops or varieties) and other management practices. Weed size should also be considered, as the product is more effective on smaller weeds.

Monitor weed populations

After herbicide application check weeds in your fields for signs of resistance development (for example, one weed species on the herbicide label may not be controlled). If resistance is suspected, prevent weed seed production in the affected area if possible, by using an alternative herbicide from a different Group. Prevent movement of resistant weed seeds to other fields by cleaning harvesting and tillage equipment when moving between fields, and always plant clean seed.

Have suspected resistant weed seeds tested by a qualified laboratory to confirm resistance and identify alternative herbicide options
