ORNAMENTALS - DIPTEROUS LEAFMINERS

General Information

PRODUCT INFORMATION

Citation Insecticide is a 75% wettable powder which, when mixed with water according to the following directions for use, will control certain insect species on designated plants.

For control of selected insects, including Dipterous leafminers (Liriomyza species) and fungus gnats, in landscape ornamentals; container-grown ornamentals; greenhouse-, lathhouse-, and shadehouse-grown ornamental bedding plants and ornamental crops; and interiorscapes; and shore flies, in greenhouse ornamental crops and interiorscapes only. For control of Dipterous leafminers, fungus gnats, and shore flies in vegetable transplants grown for consumer use.

Integrated Pest Management (IPM)

Citation Insecticide should be used in conjunction with Integrated Pest Management (IPM) practices, including the early detection of target insect populations, threshold treatment levels, cultural control practices, and procedures to manage target pest populations. Contact local extension or university personnel or refer to brochures for information on IPM practices.

Resistance Management

Citation Insecticide is a Group 17 Insecticide that contains the active ingredient cyromazine. Due to the inherent risk of the development of resistance to any pesticide product, it is strongly advised that Citation Insecticide be used in a sound resistance management program. Treatment may not be effective against labeled pests if Citation Insecticide -tolerant strains develop.

For plants that host a labeled pest with multiple generations per crop or year, use the following recommended resistance management practices that may include, but are not limited to:

- Rotating Citation Insecticide with products (such as Avid 0.15 EC Miticide/Insecticide) with different modes of action
- Avoiding treatment of successive generations with Citation Insecticide

- Using labeled rates at specified spray intervals

- Using non-chemical alternatives such as beneficial arthropods

- Using various cultural practices such as rotating susceptible to non-susceptible plants.

For additional information about implementing these or other resistance management practices, consult your local agricultural advisor or company representative.

Special Precautions to Minimize Leafminer Resistance

Citation Insecticide should not be used as the only control for leafminers. Do not apply Citation Insecticide more than 3 times at 7-day intervals to ornamental crops before switching to Avid 0.15 EC Miticide/Insecticide as an alternative control (refer to the Avid product labeling for all use directions, restrictions and precautions.). Following use of Avid, Citation Insecticide may again be applied if necessary for control. Do not make more than a total of 6 applications of Citation Insecticide to one crop. For the listed vegetable transplant crops, a non-Group 17 insecticide approved for use on these crops should be used in the rotation program. Do not apply Citation Insecticide more than 3 times at 7-day intervals before switching to a non-Group 17 insecticide. Do not make more than a total of 6 applications of Citation Insecticide to one crop.

Plant Safety

Citation Insecticide has been evaluated for safety to many greenhouse and ornamental plants as a foliar spray and a soil drench.

Phytotoxicity to ageratum, baby’s breath, chrysanthemum, cosmos, dahlia, Gerbera daisy, gloriosa daisy, impatiens, marigold, petunia, poinsettia, salvia, snapdragon, Transvaal daisy, verbena, and zinnia has not been observed at the use rates listed on this label. While many plant species and cultivars have been evaluated, individual species and cultivar should be evaluated for phytotoxicity prior to making applications to the entire crop. Before treating any crop not listed above, the grower should test Citation Insecticide for possible phytotoxic effects for at least 2 weeks on a small group of plants under the same conditions in which they will be grown.

APPLICATION INSTRUCTIONS

For control of Dipterous leafminers (Liriomyza spp.), apply 2.66 oz/A in a minimum of 100 gallons of water as a foliar spray to the point of runoff when stippling first appears. Repeat applications at 7-day intervals or as necessary to maintain control. Do not make more than a total of 6 applications to one crop.

For control of fungus gnats (Bradysia spp.) and shore flies (Scatella spp.), apply 2.66 oz of Citation Insecticide in 100 gallons of water as a spray or drench to all surfaces where insect pests may breed. This includes the potting media surfaces, bench tops, undersides of benches, and the areas under benches that may be contaminated with potting media or algae. Repeat application on a 7- to 14-day schedule to minimize reinfestation.

Citation Insecticide will not control adult stages of the insect pests. For control of adults, insecticides labeled for adult insect control should be used.

Rotational Crops

Other ornamental crops may be planted following harvest of a Citation Insecticide-treated crop. Do not rotate to any food crop for 300 days after the last application, except dried and succulent beans, Brassica leafy vegetables, bulb vegetables, cucurbit vegetables, leafy vegetables, peppers, potatoes and tomatoes. Cotton, radishes, or sweet corn may be rotated to 30 days after last application.

Electrostatic Spraying Systems, Thermal Fogger Systems, or other Low Volume Systems

Citation Insecticide has been evaluated and shown effective when applied through these application systems. To calculate the amount of product to be applied, use the appropriate amount of Citation Insecticide for the square footage to be treated with spray as listed. The amount of carrier (water) is dependent on the amount needed for adequate coverage.

Application through Irrigation Systems – Chemigation

- Citation Insecticide may be applied through hand-held or overhead irrigation equipment. Overhead irrigation systems include micro-sprinklers, mist-type irrigation (such as fog systems) and motorized booms utilizing injectors.

- DO NOT apply this product through any other type of irrigation system.

- The system must be calibrated to uniformly apply the rates specified. If you have questions about calibration, you should contact State Extension Service specialists, equipment manufacturers, or other experts.

- The irrigation system must provide uniform distribution of Citation Insecticide. Plant injury, lack of effectiveness, or illegal pesticide residues in the plant can result from non-uniform distribution.

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 systems are in place.

Chemigation Monitoring: 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.

Required System Safety Devices: 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 withdrawn 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.

Systems 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.

Specific Instructions for Public Water Systems

Public water system means a system for the provision to the public of piped water for human consumption if such system has at least 15 service connections or regularly serves an average of at least 25 individuals daily for at least 60 days out of the year.

Chemigation systems connected to public water systems must contain a functional, reduced-pressure zone, back-flow preventer (RPZ) or the functional equivalent in the water supply line upstream from the point of pesticide introduction. As an option to the RPZ, the water from the public water system should be discharged into a reservoir tank prior to pesticide introduction. A complete physical break (air gap) between the flow outlet end of the fill pipe and the top or overflow rim of the reservoir tank of at least twice the inside diameter of the fill pipe is required.

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 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.

The system must contain functional interlocking controls to automatically shut off the pesticide injection pump when the water pump motor stops or in cases where there is no water pump or when the water pressure decreases to the point where pesticide distribution is adversely affected.

Systems 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.
