GENERAL INSTRUCTIONS

Genfarm QPE 200 Herbicide is an emulsifiable concentrate herbicide designed for post-emergence control of specific grass weeds in designated broadleaf crops. As a systemic herbicide, it rapidly absorbs and readily translocates from treated foliage to the root system and growing points of the plant. Optimal application occurs when weeds are young and actively growing.

Time of Application: Weeds should be sprayed when young and actively growing. Application can be made at any stage of crop growth (excluding curcurbit crops), but allow sufficient time for the prescribed withholding period before harvest, grazing, or cutting for stockfeed. Do not apply to curcurbit crops before the five true leaf stage.

Spray Preparation: If the spray equipment has been used for sulfonylurea herbicides (e.g., metsulfuron methyl, chlorsulfuron, thifensulfuron methyl, triasulfuron), ensure the recommended sprayer equipment procedure for the previously applied product has been followed. Mix Genfarm QPE 200 Herbicide directly with water. If mixing with mancozeb or carbendazim, add them to the spray tank and mix thoroughly before adding Genfarm QPE 200 Herbicide. If the spray solution has been left standing for more than 3 hours, ensure thorough re-agitation before spraying. Do not let the spray mixture stand overnight, as resuspension may be difficult.

Use of a Surfactant/Wetting Agent: Genfarm QPE 200 Herbicide may be used with either of the following adjuvant systems:

1. A methylated and/or ethylated seed crop oil (e.g., Hasten#) at 1L/100L of the final spray volume (1% v/v).
2. A non-ionic surfactant (1000 gai/L) at 200 mL/100L of the final spray volume (0.2% v/v). Do not use Genfarm QPE 200 Herbicide with mineral-based crop oils (e.g., D-C-Trate#) or non-methylated spray oils of crop origin (e.g., Codacide# oil, Synetrol# oil) as spray adjuvants.

Crop Safety: Genfarm QPE 200 Herbicide is compatible with the herbicide diflufenican when using the non-ionic surfactant only adjuvant system. Do not add crop oil to tank mixtures of Genfarm QPE 200 Herbicide/diflufenican. Application of Genfarm QPE 200 Herbicide/diflufenican tank mix may result in temporary crop effects, such as yellow or white bleaching on the leaves. New growth and subsequent yield, however, will not be affected. To minimize crop effects, apply Genfarm QPE 200 Herbicide a minimum of 5 days before or 10 days after diflufencan application (14-21 days if weeds have been stressed).

Ground Spraying: Use between 50 and 100 liters of prepared spray/ha, with a higher spray volume for more reliable results. If weeds are large and the crop canopy is dense, increase the volume to 150 liters prepared spray/ha. Utilize sprayers with flat fan or hollow cone nozzles at 210-350 kPa to achieve an even distribution of droplets. Adjust the boom and nozzle height for proper spray coverage and ensure an even distribution with a double overlap spray pattern. Avoid overlapping boomspray widths and shut off spray booms while starting, slowing, or stopping.

Sprayer Cleanup: Thoroughly clean all traces of Genfarm QPE 200 Herbicide from application equipment immediately after use. Flush the tank, pump, hoses, and boom with several changes of water after removing nozzle tips and screens. Clean these parts separately. Failure to clean the equipment thoroughly may result in injury to subsequently sprayed cereal and grass crops.

Resistance Warning: Genfarm QPE 200 Herbicide is a member of the “Fop” (aryloxyphenoxy propionate) group of herbicides with the inhibitors of acetyl coA carboxylase mode of action. It is classified as a Group A herbicide, and there is a risk of naturally occurring weed biotypes developing resistance. Consult with your farm chemical supplier, consultant, Landmark Representative, or local Department of Agriculture or Primary Industries for strategies to minimize the risk of herbicide resistance.

Precaution: Re-entry: Do not allow entry into treated areas until the spray has dried. When prior entry is necessary, wear chemical-resistant gloves. Clothing must be laundered after each day’s use.
