General Instructions:

Rainbow Quizalofop-P-Ethyl 200 EC Selective Herbicide is an emulsifiable concentrate herbicide used post emergence for the control of certain grass weeds in specified broadleaf crops. It is a systemic herbicide, rapidly absorbed and readily translocates from the treated foliage to the root system and growing points of the plant. Applications made to grass weeds stressed due to insufficient moisture or cold temperatures may result in unsatisfactory control.

Time of Application:

For maximum benefit, weeds should be sprayed when young and actively growing. Application may be made at any stage of crop growth (except to curcurbit crops), but sufficient time must be allowed for the prescribed withholding period to expire before harvest and/or grazing or cutting for stockfeed.

IMPORTANT:

DO NOT apply Rainbow Quizalofop-P-Ethyl 200 EC Selective Herbicide to curcurbit crops before the five true leaf stage.

Spray Preparation:

If spray equipment has been previously used for the application of sulfonylurea herbicides (e.g., Metsulfuron methyl), chlorsulfuron, thifensulfuron methyl, triasulfuron, ensure that the recommended sprayer equipment procedure for the product previously applied has been followed before using the equipment for the application of Rainbow Quizalofop-P-Ethyl 200 EC Selective Herbicide. Rainbow Quizalofop-P-Ethyl 200 EC Selective Herbicide is an emulsifiable concentrate to be mixed with water and applied as a spray. Add the required amount of Rainbow Quizalofop-P-Ethyl 200 EC Selective Herbicide directly to the spray tank and mix well. If mixing with mancozeb or carbendazim, add these to the spray tank and mix thoroughly PRIOR to adding Rainbow Quizalofop-P-Ethyl 200 EC Selective Herbicide. If the spray solution has been left standing for more than 3 hours, ensure thorough re-agitation before commencement of spraying. DO NOT allow the spray mixture to stand overnight, as re-suspension may be difficult.

Use of Surfactant/Wetting Agent:

Rainbow Quizalofop-P-Ethyl 200 EC Selective Herbicide may be used with either of the following adjuvant systems:

1. A methylated and/or ethylated seed crop oil (e.g., Hasten#) at 1 L/100L of final spray volume (i.e., 1% v/v).

2. A non-ionic surfactant (1000 gai/L) at 200 ml/100L of final spray volume (i.e., 0.2% v/v).

DO NOT use Rainbow Quizalofop-P-Ethyl 200 EC Selective 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.

Compatibilities:

Rainbow Quizalofop-P-Ethyl 200 EC Selective Herbicide is compatible with the herbicides sethoxydim and clethodim. The recommended surfactant/wetting agent is the methylated and/or ethylated seed crop oil adjuvant system. Rainbow Quizalofop-P-Ethyl 200 EC Selective Herbicide is compatible with the insecticides deltamethrin, omethoate, dimethoate, methomyl, endosulfan, the fungicides carbendazim and mancozeb, and the herbicide clopyralid when using the methylated and/or ethylated seed crop oil adjuvant system. Rainbow Quizalofop-P-Ethyl 200 EC Selective 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 Rainbow Quizalofop-P-Ethyl 200 EC Selective Herbicide/diflufenican. Application of Rainbow Quizalofop-P-Ethyl 200 EC Selective Herbicide/diflufenican tank mix may result in crop effects, which usually appear as yellow or white bleaching on the leaves. New growth and subsequent yield, however, will not be affected. To minimize crop effects, apply Rainbow Quizalofop-P-Ethyl200 EC Selective Herbicide a minimum of 5 days prior to diflufenican application or a minimum of 10 days after diflufenican application. (14-21 days if weeds have been stressed).

Ground Spraying:

Use between 50 and 100 litres of prepared spray/ha, the higher spray volume gives more reliable results. If weeds are large and the crop canopy is dense, increase the volume to 150 litres prepared spray/ha. Use sprayers with flat fan or hollow cone nozzles at 210-350 kPa to give an even distribution of droplets with no less than 50% of the spray volume in the 150-300 micron range. 1100 flat fan nozzles are preferred. For proper spray coverage, adjust the boom and nozzle height according to the specification listed by the nozzle manufacturers. Ensure the spray is evenly distributed and a double overlap spray pattern is obtained. Avoid overlapping boomspray widths and shut off spray booms while starting, slowing, or stopping.

Sprayer Cleanup:

Thoroughly clean all traces of Rainbow Quizalofop-P-Ethyl 200 EC Selective Herbicide from application equipment immediately after use. Flush tank, pump, hoses, and boom with several changes of water after removing nozzle tips and screens (clean those parts separately). Failure to thoroughly clean the equipment may result in injury to subsequently sprayed cereal and grass crops. If spray equipment has been previously used for the application of sulfonylurea herbicides (e.g., Metsulfuron methyl), thifensulfuron methyl, chlorsulfuron, triasulfuron, ensure that the recommended sprayer cleanup procedure of the product previously sprayed has been followed before using the equipment for the application of Rainbow Quizalofop-P-Ethyl 200 EC Selective Herbicide.

Resistant Weeds Warning:

Rainbow Quizalofop-P-Ethyl 200 EC Selective Herbicide is a member of the "Fop" (aryloxyphenoxy propianate) group of herbicides. It has the inhibitors of acetyl coA carboxylase mode of action. For weed resistance management, Rainbow Quizalofop-P-Ethyl 200 EC Selective Herbicide is a Group A herbicide. Some naturally occurring weed biotypes resistant to Rainbow Quizalofop-P-Ethyl 200 EC Selective Herbicide and other Group A herbicides may exist through normal genetic variability in any weed population. The resistant individuals can eventually dominate the weed population if these herbicides are used repeatedly. These resistant weeds will not be controlled by Rainbow Quizalofop-P-Ethyl 200 EC Selective Herbicide or other Group A herbicides. Since the occurrence of resistant weeds is difficult to detect prior to use, Shandong Rainbow International Co., Ltd accepts no liability for any losses that may result from failure of Rainbow Quizalofop-P-Ethyl 200 EC Selective Herbicide to control resistant weeds. Strategies to minimize the risk of herbicide resistance are available. Consult your farm chemical supplier, consultant, Rainbow's Representative, local Department of Agriculture or Primary Industries.
