TUBEROUS AND CORM VEGETABLES (SUBGROUP 1C)
- For use only on crops listed on this label.
- Do not apply more than one application to annual crops, and no more than 3.5 lbs of fluensulfone (112 fl. oz. of this product) per acre, per calendar year.
Although resistance in nematode populations has not been proven, repeated exclusive use of any product may lead to a reduction in control due to enhanced biodegradation or other causes. Rotation with nematicides with a different mode of action is suggested. Contact your Cooperative Extension specialist, certified crop advisor and or product manufacturer for additional resistant management recommendations.
NIMITZR should be used as part of an Integrated Pest Management (IPM) program to control nematodes. IPM programs using cultural practices, sanitation, planting of nematode resistant varieties, scouting or other detection methods, proper pest identification and rotation of nematicides with different modes of action will help prevent economic nematode damage.
NIMITZ can be used to control and suppress the following nemotodes Root-knot (Meloidogyne spp.), Potato cyst* (Globodera spp.), Needle* (Longidorus africanus), Lance* (Hoplolaimus spp.), Sting* (Belonolaimus spp.), stubby root* (Trichodorus and Paratrichodorus spp.), and Lesion (Pratylenchus spp.). A successful treatment with NIMITZ will not eradicate nematode populations. It is recommended to apply when the target nematodes are active (at least 43 oF soil temperature for Columbia Root-knot nematode (M. chitwoodi) and at least 55 oF for more common Root-knot nematodes).
*Not for use in California.
Applications must be broadcast incorporated, banded and incorporated, or by chemigation. Make soil applications only in accordance with directions and conditions of use described in this label. Treated areas can be covered with plastic or left uncovered according to planting practices.
Tank Mixing: It is the pesticide user’s responsibility to ensure that all products are registered for the intended use. Read and follow the applicable restrictions and limitations and directions for use on all product labels involved in tank mixing. Users must follow the most restrictive directions for use and precautionary statements of each product in the tank mixture.
Do not apply NIMITZ with any other product before testing for physical and chemical compatibility of the mixture. To determine compatibility, pour the required proportions of the product(s) into a suitable container. After mixing, wait for 30 minutes and check to see if the product remains mixed. If the product remains mixed, it is considered physically compatible. It is the pesticide user’s responsibility to ensure that all products in a tank mix are registered for the intended use. Users must follow the most restrictive directions and precautionary language of the products of the mixture (for example, first aid from one product, spray drift management from another).
Use mixed product as soon as possible following mixing and preferably within the same day of mixing.
Use NIMITZ in accordance with all applicable label directions. NIMITZ can be applied in any season when soil conditions permit and nematodes are active. Uniform application and incorporation to moist soils is essential.
Apply NIMITZ to a moist, well-prepared seedbed. Ensure soils have sufficient moisture to support plant growth. If soils are not free of clods, debris and plant residues thoroughly incorporate them into the soil to prevent interference with application or control.
Lack of effectiveness, crop injury or illegal pesticide residues in the crop can result from non-uniform distribution of product. Consult your equipment manufacturer, State Extension specialist or ADAMA representative for calibration or application questions.
MIXING, LOADING AND HANDLING INSTRUCTIONS
Add the required amount of NIMITZ to the water in the spray tank or injection pre-tank and mix well. Continue agitation at frequent intervals during application. If NIMITZ is to be mixed with other products or fertilizers, test the physical compatibility of the mixture as described above prior to use.
NOTE: Thoroughly clean application equipment prior to use and before using for application of other pesticides.
SOIL MOISTURE MANAGEMENT
Soil moisture management can have an influence on product efficacy. Ensure soil moisture is greater than or equal to 50% of soil capacity. It is recommended to irrigate with 0.5 to 1 inch of water 3-5 days after application. If applied by drip irrigation, make sure that the soil is pre-wetted to allow the product to move uniformly from shoulder to shoulder and throughout the bed as it is being drip irrigated.
For optimal performance, all applications must be incorporated by water and/or mechanical means to a depth of 4-8 inches. Resume a normal irrigation schedule immediately after planting. Excessive moisture immediately after application may cause this product to move past the targeted zone.
When no irrigation is available mechanically incorporate NIMITZ.
Apply at labeled rate for each crop using conventional application equipment a minimum of 7 days before planting and 7 days before seeding. For Brassica (cole) leafy vegetables, Japanese mustard spinach, hot herb mustard spinach, Japanese white radish (daikon), and turnip, apply at a minimum of 30 days prior to transplanting or seeding. Prepare the spray mix by adding the product to the spray tank with a minimum of 20 gallons of water per acre to obtain a uniform application. Maintain sufficient agitation during mixing and application to ensure a homogeneous spray solution. Uniformly apply the spray mix over the field and mechanically incorporate to a depth of 4-8 inches with incorporation equipment to ensure even distribution. It is recommended to irrigate 3-5 days after application with the quantity of water recommended in Chart 1. Following planting, resume normal irrigation practices.
Drift Management: Do not make application at a boom height greater than 20 inches above the surface of the soil, and use nozzles that produce coarse droplets (>300 microns) to reduce evaporation and drift. Do not apply when the wind speed favors drift beyond the areas intended for treatment.
Chart 3 may be used to determine the amount of product required based on bed width, length and use rate.
Apply the spray mixture across the band and uniformly incorporate to 6-8 inches avoiding dilution outside the band, 7-10 days before planting. It is recommended to irrigate after application with the timing and water quantity recommended in Chart 1. Following planting, resume normal irrigation practices. Rates are not to be concentrated in the row instead, they are to be applied based on the treated acre (the acre within the band). Drift Management: Do not make application at a boom height greater than 20 inches above the surface of the soil, and use nozzles that produce coarse droplets (>300 microns) to reduce evaporation and drift.
Chemigation DRIP IRRIGATION: NIMITZ can be applied through low volume (ground or underground) drip, drip tape, strip tubing, drip line, micro-emitter or micro-sprinkler application. Wet the bed prior to application to ensure maximum distribution of NIMITZ.Prepare the application mix as indicated in Chart 2. The amount of product required for a drip application will vary with the width of the planting bed, row length and wetting front of the application. Use Chart 3 to determine the amount of product required. Assume the wetting front is the same as the bed width for up to a maximum of 36 inches, determining the rate to apply. For drip irrigation, NIMITZ can be added directly to the irrigation system and applied with sufficient water and duration to uniformly wet the irrigation zone width or the entire bed width and root zone 6-8 inches deep no less than 7 days before planting. Rates are to be calculated based on the width of the application zone comprising the treated acre.
The amount of water needed for an application will depend upon the initial level of soil moisture, the soil type, % organic matter and condition and the placement of the drip tape(s) as well as drip tape emitter spacing, etc. Allow enough time in the application cycle to charge the irrigation system, then apply NIMITZ into the target root zone and flush the system lines with water. Injection timing during the irrigation cycle depends on soil type and drip tape placement. Do not over apply system rinse water and wash the NIMITZ from the root zone. Irrigate after application based on the timings and quantities in Chart 1. Following planting, resume normal irrigation practices. NIMITZ may not be applied in conjunction with a drip line cleaning product as performance may be reduced.
The entire irrigation system including emitters need to be checked to ensure the system is operating normally before injecting NIMITZ. Do not connect an irrigation system (including greenhouse systems) used to apply pesticides to any public water system unless the pesticide label prescribed safety devices for public water systems are in place. In addition, check local and state regulations regarding the injection of pesticides into public water systems. A person knowledgeable of the chemigation system and responsible for its operation, or a person under the supervision of the responsible person, is responsible to shut the system down and make necessary adjustments as needed. Follow manufacturer’s instructions to maintain the drip system at a low enough pressure to prevent fogging and/or misting during applications. Inject NIMITZ into the irrigation system after the filter(s) and automatic back flush system in order to avoid back flushing of treated water.
Systems using a pressurized water and pesticide injection system must meet the following requirements:
1. The system must contain a functional check valve, vacuum relief valve and low pressure drain appropriately located on the irrigation pipeline to prevent water source contamination from backflow.
2. The pesticide injection pipeline must contain a functional, automatic, quick-closing check valve to prevent the flow of fluid back toward the injection pump.
3. The pesticide injection pipeline must also contain a functional, normally closed, solenoid-operated valve located on the intake side of the injection pump and connected to the system interlock to prevent fluid from being withdrawn from the supply tank when the irrigation system is either automatically or manually shut down.
4. The system must contain functional interlocking controls to automatically shut off the pesticide injection pump when the water pump motor stops.
5. The irrigation line or water pump must include a functional pressure switch that will stop the water pump motor when the water pressure decreases to the point where pesticide distribution is adversely affected. 6. Systems must use a metering pump, such as a positive displacement injection pump (e.g. diaphragm pump) effectively designed and constructed of materials compatible with pesticides and capable of being fitted with a system interlock.
SPRINKLER APPLICATION: Apply NIMITZ only through sprinkler (including center-pivot, lateral move, or solid set) irrigation systems.
Crop injury, lack of effectiveness, or illegal pesticide residues in the crop can result from non-uniform distribution of treated water.
Calibration: (Center-pivot and Self-Propelled Lateral Move Systems): Sprinkler irrigation systems must be accurately calibrated for application of NIMITZ. Greater accuracy in calibration (and distribution) will be achieved by injecting a larger volume of a more dilute mixture of product and water per hour. Follow these steps below to calibrate center pivot or lateral move systems.
1. Determine number of minutes required to make one complete revolution while applying 0.6 to 1 inch of water per acre.
2. With the system at operating pressure, determine the exact number of minutes required to inject one gallon of water.
3. Divide the time required to for one revolution (step 1) by the time required to inject one gallon (step 2). This gives the total number of gallons of product-water mixture to be added to the nurse tank.
4. Add required amount of water to nurse tank and start the agitation system. Then add sufficient NIMITZ at the listed rate (See Broadcast Applications) to the nurse tank.
EXAMPLE: If 20 hours (1200 minutes) were required for one revolution and if 2 minutes were required to inject one gallon, then a total of 600 gallons of productwater mixture are required (1200/2 = 600); to treat 135 acres at 5 pints/acre, 675 pints (84 gallons and 3 pints) of NIMITZ are required.
If you have questions about calibration, you should contact State Extension Service Specialists, equipment manufacturers or other experts.
Do not connect an irrigation system (including greenhouse systems) used for pesticide application to a public water system unless the pesticide label-prescribed safety devices for public water system are in place.
A person knowledgeable of the chemigation system and responsible for its operation, or under the supervision of the responsible person, shall shut the system down and make necessary adjustments should the need arise.
The system must contain a functional check valve, vacuum relief valve, and low pressure drain appropriately located on the irrigation pipeline to prevent water source contamination from backflow. The pesticide injection pipeline must contain a functional, automatic, quick closing check valve to prevent the flow of fluid back toward the injection pump.
The pesticide injection pipeline must also contain a functional, normally closed, solenoid-operated valve located on the intake side of the injection pump and connected to the system interlock to prevent fluid from being with-drawn from the supply tank when the irrigation system is either automatically or manually shut down.
The system must contain functional interlocking controls to automatically shut off the pesticide injection pump when the water pump motor stops.
The irrigation line or water pump must include a functional pressure switch which will stop the water pump motor when the water pressure decreases to the point where pesticide distribution is adversely affected. System must use a metering pump, such as a positive displacement injection pump (e.g., diaphragm pump) effectively designed and constructed of materials that are compatible with pesticides and capable of being fitted with a system interlock.
Do not apply when wind speed favors the drift beyond the area intended for treatment.
Maintain continuous agitation in the injection nurse tanks during the herbicide application, sufficient to keep herbicide in suspension.
Apply specified dosage in 0.6 to 1 inch of water per acre as a continuous injection in center pivot and lateral move systems or in the last 15 to 30 minutes of set in permanent solid set sprinkler systems.
Application of less than the quantity of irrigation water indicated on this label may result in decreased product performance by not allowing chemical to penetrate deep into the soil profile. Where sprinkler distribution patterns do not overlap sufficiently unacceptable performance may result.
Where sprinkler distribution patterns overlap excessively crop injury may result. Allow sufficient time for pesticide to be flushed through all lines and all nozzles before turning off the irrigation water. To ensure that lines are flushed and free of remaining pesticide, an indicator dye may be injected into the lines to mark the end of the application period.
Use of a minimum of 1-part water to 1-part NIMITZ for injection. The use of a larger volume of water will ensure greater accuracy and more uniform distribution. Consult State Agricultural Experiment stations for State Agricultural Extension Service for additional information as the time of applications needed will vary with the local conditions.
a NIMITZ label or any crop for which a tolerance exists for the active ingredient as soon as practical following the last application.
