BLAZER is a selective post-emergence herbicide which can be applied alone or in a tank mix combination with BASAGRAN® or BASAGRAN FORTE as a single application for the control of certain broadleaf weeds and suppression of specific perennial weeds in soybeans. For best results, apply BLAZER herbicide when the weeds are small and actively growing. It is important to have good spray coverage on the weeds as BLAZER works mainly by contact action. Failure to follow the suggested application rate and timing may result in unsatisfactory control.
APPLY BLAZER USING GROUND EQUIPMENT ONLY. DO NOT APPLY BY AIR.
Soybeans are tolerant to a postemergence application of BLAZER when applied at the recommended growth stages and suggested rate. Soybeans may exhibit speckling, bronzing and/or leaf burn. The trifoliolate leaf emerging at the time of application may be distorted. Soybeans usually outgrow these conditions and continue to grow at a normal rate with no adverse effect on vigour, maturity, or crop yield.
DIRECTIONS FOR USE
TIMING OF APPLICATION
To ensure most effective weed control, correct timing is very important. Apply BLAZER alone or the tank mix of BLAZER + BASAGRAN or BASAGRAN FORTE when the susceptible weeds are young and actively growing and the soybeans are in the 1-3 trifoliolate leaf stage. This is usually 24 to 28 days after soybean planting in most years. Do not apply before the first trifoliolate leaf stage of the soybean. BLAZER and the tank mix of BLAZER + BASAGRAN or BASAGRAN FORTE provide the best weed control when maximum daily temperatures are expected to be above 21ºC. In solid seeded or broadcast soybean plantings, BLAZER and the tank mix of BLAZER + BASAGRAN or BASAGRAN FORTE should be applied when the soybeans are in the 1-2 trifoliolate leaf stage in order to ensure good spray coverage of weeds. Later applications may result in poor weed control because of advanced weed growth or poor coverage due to the crop canopy covering the weeds.
Apply BLAZER at 1.25 L/ha. When applying BLAZER at 1.25 L/ha, add 0.5% v/v (1-2 L/ha depending on application volume) of ASSIST Oil Concentrate. This treatment will provide control of common ragweed and redroot pigweed.
Apply BLAZER at 2.5 L/ha. Do not add oils or surfactants to the spray mixture when applying the 2.5 L/ha rate of BLAZER alone.
BLAZER plus BASAGRAN or BASAGRAN FORTE tank mixture
BLAZER can be tank mixed with BASAGRAN or BASAGRAN® FORTE for control of additional broadleaf weeds.
BLAZER and BASAGRAN
When tank mixing BLAZER and BASAGRAN, use ASSIST Oil Concentrate at a rate of 1.0 to 2.0 L/ha depending on climatic conditions and the spray volume used. Under hot, humid conditions, restrict the ASSIST rate to 1.0 L/ha.
Use the following application rates when tank mixing BLAZER with BASAGRAN:
BLAZER at 0.63 L/ha plus BASAGRAN at 1.75 L/ha plus ASSIST Oil Concentrate at 1.0 to 2.0 L/ha will control the weeds listed in Table 2 up to the specified leaf stage.
BLAZER AND BASAGRAN FORTE
Use the following application rates when tank mixing BLAZER with BASAGRAN FORTE:
BLAZER at 1.25 L/ha plus BASAGRAN FORTE at 1.25 L/ha will control the weeds listed in Table 2 up to the specified leaf stage.
Use this treatment where common ragweed and/or redroot pigweed are the dominant weed species present.
BLAZER at 0.63 L/ha plus BASAGRAN FORTE at 1.75 L/ha will control the weeds listed in Table 2 up to the specified leaf stage.
Use this treatment where lamb’s-quarters and weeds other than common ragweed and redroot pigweed are the dominant weed species present.
Do not use ASSIST Oil Concentrate or other surfactant with the BLAZER plus BASAGRAN FORTE tank mixture.
Refer to BASAGRAN or BASAGRAN FORTE label for additional restrictions and limitations.
1. Shake container well before using.
2. Clean spray tank with suitable tank cleaner and fill the clean and empty spray tank one-half full with water. Begin agitation and add the required amount of BLAZER.
3. If required, add the correct amount of BASAGRAN FORTE or BASAGRAN followed by ASSIST. Empty containers should be triple-rinsed with water and the rinsing added to the spray tank while maintaining agitation.
4. Add the remainder of water to the spray tank and maintain sufficient agitation during mixing and spraying to ensure a uniform spray mixture.
5. If an oil film starts to build up in the tank, drain it and clean the tank with detergent solution.
6. Thoroughly clean the spray tank immediately after use by flushing the system with clean water containing detergent.
RESTRICTIONS AND LIMITATIONS
1. Do not treat any crop other than soybeans.
2. Do not use BLAZER with additives, pesticides or fertilizers not specifically recommended on this label.
3. Do not apply BLAZER to soybeans that have been subjected to stress from conditions such as:
b) hail damage
d) hot, humid weather
f) widely fluctuating temperatures
g) prolonged cold weather
h) injury from prior herbicide applications as crop injury may result.
4. Rainfall within 6 hours of application may reduce effectiveness of spray, particularly on perennial weeds.
5. When BLAZER is applied beyond the maximum weed heights, limited to unsatisfactory weed control will result.
6. Cool weather conditions or drought will delay herbicide activity and if prolonged, may result in poor weed control.
7. Cultivation before or during the application of BLAZER or the tank mix of BLAZER + BASAGRAN or BASAGRAN FORTE is not recommended. If cultivation is desired, wait until 7 days after application.
8. DO NOT APPLY BLAZER BY AIR.
9. Avoid spray drift which could result in damage to non-target crops.
10. DO NOT apply this product directly to aquatic habitats (such as lakes, rivers, sloughs, ponds, prairie potholes, creeks, marshes, streams, reservoirs, ditches and wetlands), estuaries or marine habitats.
11. Do not apply BLAZER on soybeans grown on sand or loamy sand soils.
12. CAUTION: Do not graze treated crop or cut for hay; sufficient data are not available to support such use.
13. DO NOT enter or allow worker entry into treated areas during the restriced entry interval (REI) of 12 hours.
14. Field sprayer application: DO NOT apply during periods of dead calm. Avoid application of this product when winds are gusty. DO NOT apply with spray droplets smaller than the American Society of Agricutlural Engineers (ASAE) medium classification.
15. Buffer zones: A buffer zone of 15 meters is required between the point of direct application and the closest downwind edge of sensitive terrestrial habitats (such as grasslands, forested areas, shelter belts, woodlots, hedgerows, pastures, rangelands and shrublands). When a tank mixture is used, consult the labels of the tank-mix partners and observe the largest (most restrictive) buffer zones of the products involved in the tank mixture.
16. DO NOT contaminate irrigation or drinking water supplies or aquatic habitats by cleaning of equipment or disposal of wastes.
For resistance management, BLAZER is a Group 14 herbicide. Any weed population may contain or develop plants naturally resistant to BLAZER and other Group 14 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 resistancemanagement strategies should be followed.
To delay herbicide resistance:
Where possible, rotate the use of BLAZER or other Group 14 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.
