NUFARM - herbicide

Nufarm CHAPERONE Herbicide is recommended for selective postemergence control of broadleaf weeds in soybeans. Nufarm CHAPERONE Herbicide is formulated as a dry flowable granule to be mixed in water and applied as a uniform broadcast spray. It is noncorrosive, nonflammable, nonvolatile, and does not freeze. Keep product away from excess moisture or physical damage during storage and prior to mixing in the spray tank. Nufarm CHAPERONE Herbicide must be applied with a recommended surfactant early postemergence to the main flush of actively growing weeds. Warm, moist growing conditions promote active weed growth and enhance the activity of Nufarm CHAPERONE Herbicide by allowing maximum foliar uptake and contact activity. Weeds hardened off by environmental stress may not be adequately controlled and regrowth may occur. Nufarm CHAPERONE Herbicide may only be applied using ground equipment. For best results, ensure thorough spray coverage of target weeds. Nufarm CHAPERONE Herbicide rapidly stops growth of susceptible weeds. However, typical symptoms (discoloration) of dying weeds may not be noticeable for 1 to 3 weeks after application, depending on growing conditions and weed susceptibility. Favourable growing conditions following treatment promote the activity of Nufarm CHAPERONE Herbicide while cold, dry conditions delay the activity. Degree of control and duration of effect depend on weed sensitivity, weed size, crop competition, growing conditions and spray coverage.  

Nufarm CHAPERONE Herbicide applications made during or immediately following a large and rapid fluctuation in temperature (20 C or greater difference between night time lows and daytime highs) which stresses the crop may increase the potential for crop injury. Apply Nufarm CHAPERONE Herbicide when temperature is expected to be below 28 degrees C within 12 hours of application. Apply when the minimum temperature in the 24 hours before and after application is above 5 degrees C. If soybeans have been injured by frost, wait at least 48 hours before applying the herbicide(s).

 Optimum timing of Nufarm CHAPERONE Herbicide for annual broadleaf weed control is when soybeans are in the 1 to 3 trifoliate stage of growth. Do not apply Nufarm CHAPERONE Herbicide before the first trifoliate has fully expanded or after the initiation of flowering. Nufarm CHAPERONE Herbicide can be applied up to 60 days before harvest.  
Rate: Use 36 grams of Nufarm CHAPERONE Herbicide per hectare.
A non‐ionic surfactant such as AGRAL 90, CITOWETT PLUS, or AG‐SURF must also be used at 0.2% v/v. For best results, apply to young actively growing weeds before the soybean canopy closes. Weeds that emerge after treatment may not be controlled.
NOTE: Do not apply to soybeans that have been stressed by severe weather conditions such as frost or hot, humid weather as crop injury may result. If rain occurs after application, control may be reduced. Two ‐ four hours of dry weather are needed to allow Nufarm CHAPERONE Herbicide to be absorbed by weed foliage.

a. Nufarm CHAPERONE Herbicide + glyphosate
Apply Nufarm CHAPERONE Herbicide at 36 grams per hectare, tank mixed with glyphosate (present as potassium salt, isopropylamine salt, or di‐ammonium salt) and adjuvant (where required).
Consult the respective glyphosate herbicide labels for specific instructions for 'Directions for Use', Precautions, and for other weeds controlled by glyphosate herbicide. If rain occurs after application, control may be reduced. 2 ‐ 4 hours of dry weather are needed to allow Nufarm CHAPERONE Herbicide to be absorbed by weed foliage.
b. Nufarm CHAPERONE Herbicide + ASSURE II Herbicide:
Consult the label of the tank mix partner product, and follow the most stringent set of precautions, restrictions and directions for use. Consult the ASSURE II Herbicide label for specified rates and optimum leaf stage timing for grassy weeds. If leaf stages of the grass and broadleaf weeds do not coincide, a sequential application of the grass and broadleaf herbicides is required to ensure satisfactory control.

1. Fill clean tank about 1/4 full with fresh water.
2. Turn on full agitation.
3. Add the proper amount of Nufarm CHAPERONE Herbicide to the water in the spray tank with the agitator running. Maintain full agitation until product is fully dispersed. Continuous agitation is required to keep the product in suspension.  
4. After Nufarm CHAPERONE Herbicide has been well mixed and is in suspension, add the tank mix partner, if applicable.
5. Add a recommended amount of spray adjuvant (if required).
6. Fill the remainder of the spray tank with clean water.
On repeat tank loads, ensure that the amount of spray solution left in the tank from the previous load is less than 10% of the volume about to be mixed.  
Agitation is required for uniform mixing and application.  
The optimum water volume for Nufarm CHAPERONE Herbicide application is 140‐190 litres of water per hectare (minimum of 100 litres of water per hectare).  
Flat fan nozzles are recommended. Use 50 mesh filter screens or larger.  
Use spray preparation of Nufarm CHAPERONE Herbicide within 24 hours or product degradation may occur resulting in a loss of weed control. Use vigorous agitation to thoroughly disperse spray mixtures that have been allowed to stand in the tank. NOTE: Nufarm CHAPERONE Herbicide will degrade in acidic or highly alkaline water. Mix no more than can be used in one day. If spraying is interrupted, thoroughly re‐agitate the spray mixture before resuming spraying.   Do not mix or load where there is potential to contaminate wells or aquatic systems.

To avoid subsequent injury to crops other than soybeans immediately after spraying and prior to spraying other crops, thoroughly remove all traces of Nufarm CHAPERONE Herbicide from mixing and spray equipment as follows:
1. Drain tank; then flush tank, boom and hoses with clean water for a minimum of ten minutes. Visually inspect tank to assure removal of all visible residues of Nufarm CHAPERONE Herbicide. If necessary, repeat step 1. DO NOT CLEAN SPRAY EQUIPMENT NEAR WELLS, AQUATIC SYSTEMS, OR OTHER WATER SOURCES, OR NEAR DESIRABLE VEGETATION.  
2. Fill tank with clean water while adding 1 litre household ammonia (containing minimum 3% ammonia) per 100 litres of water. Flush solution through boom and hoses, and then add more water to completely fill tank. Allow to sit for 15 minutes with agitation. Again flush the hoses, boom and nozzles with the cleaning solution and drain tank.
3. Remove the nozzles and screens and clean separately in a bucket containing cleaning agent and water.
4. Repeat Step 2.
5. Thoroughly rinse the tank with clean water for a minimum of 5 minutes, flushing water through the hoses and boom.

Nufarm CHAPERONE Herbicide is degraded by natural soil processes, and field tests have shown that the following crops may safely be planted at the prescribed interval following soybeans that have been treated with Nufarm CHAPERONE Herbicide. The recropping intervals are dependent on the pH of the soil, as well as the sensitivity of the specific rotational crop.

Select a representative area or areas of the field previously treated with Nufarm CHAPERONE Herbicide to plant your bioassay crop(s). Be sure to consider factors such as size of field, soil texture, drainage and turn‐around areas when selecting the site(s) that are most representative of the soil conditions in the field. On large fields, more than one site may be needed in order to obtain reliable results. Plant the test strips perpendicular to the direction in which the field was sprayed. The strips should be long enough to cross the width of several spray swaths. Large test strip areas are more reliable than small ones. Use standard tillage and seeding equipment to plant the bioassay. Prepare a seed bed and plant the crops and varieties you want the option of growing the following year. It is important to use the same planting time, conditions, techniques and cultural practices you normally use to plant and grow the bioassay crop(s). Also plant into an adjacent area not treated with Nufarm CHAPERONE Herbicide to use as a comparison. As the crop(s) emerges and grows, examine these key points in Nufarm CHAPERONE Herbicide treated and non‐treated areas: crop stand, root development, rate of growth, plant colour, vigour and yield. Allow the bioassay crop(s) to grow to maturity while making your observations. Do not overspray the test strips with herbicides that may damage the bioassay crop(s). If the bioassay indicates that Nufarm CHAPERONE Herbicide residues are still present, continue cropping only to those crops listed on the label and do not rotate to other crops until bioassay results indicate that susceptible crops are growing normally.

Do not apply Nufarm CHAPERONE Herbicide during periods of intense rainfall or to soils saturated with water.
Do not apply directly to standing or running water. Do not apply in areas where surface water from the treatment site can run off to adjacent cropland, either planted or to be planted, or into bodies of water (such as streams, ponds, rivers, lakes, and irrigation water), wetlands, or wells. Applications should only be made when there is no hazard of spray drift contaminating non‐target land areas since very small quantities of the Nufarm CHAPERONE Herbicide spray solution may severely injure susceptible crops and other sensitive terrestrial habitats during both growing and dormant periods.
Do not apply to soybeans that have been stressed by severe weather conditions, frost, low fertility, drought, water saturated soil, disease or insect damage as crop injury may result.
Under extreme weather conditions, such as hot, dry weather, excessive moisture, or frost, weed control may be reduced.
Rainfall within 4 hours after application of Nufarm CHAPERONE Herbicide may reduce weed control.
Because soybean varieties differ in their tolerance to herbicides, limit first use of Nufarm CHAPERONE Herbicide to a small area of each variety prior to adoption as a field practice.
Overspray or drift to important aquatic and terrestrial wildlife habitats should be avoided. Leave a 16 metre buffer zone between the last spray swath and bodies of water such as ponds, lakes, rivers, and streams.
Leave a 39 metre buffer zone between the last spray swath and wetlands, vegetated areas at the edges of bodies of water, woodlots and shelterbelts, and other terrestrial wildlife habitats.
Nufarm CHAPERONE Herbicide must not be applied within 60 days of harvest.
Make only one application of Nufarm CHAPERONE Herbicide per season.
Do not graze the treated crop or cut for hay; sufficient data is not available to support such use.
Do not apply Nufarm CHAPERONE Herbicide to soybean grown on soil of pH  ≥  8.0 due to risk of rotational crop injury.

For resistance management, Nufarm CHAPERONE Herbicide is a Group 2 herbicide. Any weed population may contain or develop plants naturally resistant to Nufarm CHAPERONE Herbicide and other Group 2 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. To delay herbicide resistance:
Where possible rotate the use of Nufarm CHAPERONE Herbicide or other Group 2 herbicides with different herbicide groups that control the same weeds in a field.
Use tank mixtures with herbicides from a different group when such use is permitted
Herbicide use should be based on an IPM program that includes scouting, historical information related to herbicide use and crop rotation, and considers tillage (or other mechanical), cultural, biological and other chemical control practices.
Monitor treated weed populations for resistance development.
Prevent movement of resistant weed seeds to other fields by cleaning harvesting and tillage equipment and planting clean seed.  
Contact your local extension specialist or certified crop advisors for any additional pesticide resistance management and/or integrated weed‐management recommendations for specific crops and weed biotypes.
