Marathon II is an insecticide that provides effective control and instant knockdown of sucking and piercing insects in greenhouses, nurseries, interior plantscapes, and similar areas. It contains Imidacloprid as its active ingredient which effectively controls insects such as aphids, adelgids, fungus gnat, lacebugs, leafminers, leafhoppers, mealybugs, psyllids, thrips, whiteflies and more on ornamentals, fruit and nut trees, and vegetable plants. This offers up to 12 weeks of systemic activity when applied to the soil surface and is highly translaminar as a foliar spray resulting in quick eradication of pests. It is recommended to apply to the growing part of the plant for better absorption of the active ingredient. This flowable formulation provides efficient control using low rates, making it more economical to use.
FOR FOOD/FEED CROPS AND COMMERCIALLY GROWN ORNAMENTALS NOT UNDER CONTRACT FOR POLLINATION SERVICES BUT ARE ATTRACTIVE TO POLLINATORS
Do not apply this while bees are foraging. Do not apply this until flowering is complete and all petals have fallen unless one of the following conditions is met:
The application is made to the target site after sunset
The application is made to the target site when temperatures are below 55 degrees Fahrenheit
The application is made in accordance with a government-initiated public health response
The application is made in accordance with an active state-administered apiary registry program where beekeepers are notified no less than 48-hours prior to the time of the planned application so that the bees can be removed, covered or otherwise protected prior to spraying
The application is made due to an imminent threat of significant crop loss, and a documented determination consistent with an IPM plan or predetermined economic threshold is met. Every effort should be made to notify beekeepers no less than 48-hours prior to the time of the planned application so that the bees can be removed, covered or otherwise protected prior to spraying.
Do not apply MARATHON II while bees are foraging. Do not apply MARATHON II to plants that are flowering. Only apply after all flower petals have fallen off.
Do not apply this in a way that will contact workers or other persons, either directly or through drift. Only protected handlers may be in the area during application. For any requirements specific to your State or Tribe, consult the agency responsible for pesticide regulation.
APPLICATION TO ORNAMENTALS AND VEGETABLE PLANTS
MARATHON II may be used to control insect pests on ornamental and vegetable plants in nurseries and greenhouses and interior plantscapes. Insect protection is achieved because MARATHON II is a systemic product and the active ingredient moves upward into the plant system. For best results MARATHON II should be applied to the growing part of the plant for more absorption of the active ingredient. Nitrogen containing fertilizer may be added to the solution to aid in the uptake of the active ingredient where applicable. MARATHON II may be applied as a foliar spray or by soil applications such as soil injection, drenches, chemigation and broadcast sprays.
Soil applications to plants with woody stems will require applications of MARATHON II before expected pests infestations due to the delay in the uptake of the active ingredient and the time until the product is taken up throughout the plant.
For outdoor ornamentals, do not exceed a total of 1.6 pints (0.4 lb of active ingredient) per acre per year.
Bark Media: The length of protection after treatment with MARATHON II may be shortened if the media has 30% or more bark content.
RESISTANCE: Some insects are known to develop resistance to insecticides after repeated use. As with any insecticide, the use of this product should conform to resistance management strategies established for the use area. Consult your Cooperative Extension Service for resistance management strategies and recommended pest management practices for your area.
Application Equipment For Ornamentals And Vegetable Plants
MARATHON II mixes with water and may be applied with different types of application equipment. After mixing with the correct amount of water, follow the application directions for the selected use pattern.
For applications on hard to wet foliage such as holly, pine, or ivy, the use of a spreader/ sticker is recommended. For application by concentrate or mist type spray equipment, the same amount of product should be used on the area sprayed, as would be used in a dilute application.
MARATHON II is compatible with frequently used fungicides, miticides, liquid fertilizers. Compatibility may be tested in a small jar by using the correct proportion of products if compatibility information is not available.
APPLICATION THROUGH IRRIGATION SYSTEMS
MARATHON II may be applied alone or as a tank mixture with other chemicals or pesticides registered for application through irrigation systems. The normal dilution ratio is 1:100 to 1:200, depending on the system. Always meter the product into the irrigation water during the first part of the irrigation cycle. The product may be mixed separately prior to injection. Agitation may be necessary if the mixture is allowed to stand more than 24 hours.
Remove scale, pesticide residue and other foreign matter from the tank and entire irrigation system.
Apply MARATHON II only through micro irrigation (individual spaghetti tubes), drip irrigation, overhead irrigation, ebb and flood, or hand-held or motorized calibrated irrigation equipment.
Do not apply this product through any other type of irrigation system. Crop injury or lack of effectiveness can result from nonuniform distribution of treated water.
If you have any questions about calibration, contact your State Extension Service specialist, equipment manufacturers or other experts in this area.
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.
A person knowledgeable of the chemigation system and responsible for its operation, or a person who is under the supervision of the responsible person, shall shut the system down and make necessary adjustments should the need arise.
Do not graze treated areas or use clippings for treated areas for feed or forage. Avoid runoff or puddling of irrigation water following application.
Do not apply MARATHON II to soils which are water logged or saturated, which will not allow penetration into the root zone of the plants.
Do not allow leachate run out for the first 10 days after application, in order to retain the product and facilitate full plant uptake of the active ingredient.
For outdoor ornamentals grown in beds or turf, applications of MARATHON II cannot exceed a total of 1.6 pt (0.4 lb of active ingredient) per acre per year.
Food Crops: Treated areas may be replanted with any crop specified on an imidacloprid label, or with any crop for which a tolerance exists for the active ingredient.
For crops not listed on an imidacloprid label, or for crops for which no tolerances for the active ingredient have been established, a 12 month plant-back interval should be observed.
Do not apply this product, by any application method to linden, basswood, or other Tilia species.
APPLICATION TO GRASSY AREAS IN NURSERIES
MARATHON II may be used on nursery grass in areas such as under or around field or container grown plants, on roadways or other grassy areas in or around nurseries. MARATHON II is not for use on commercial sod farms.
MARATHON II controls soil inhabiting pests of grassy areas of nurseries, such as Northern and Southern masked chafers, Cyclocephala borealis, C. immaculata, and/or C. lurida; Asiatic garden beetle, Maladera castanea; European chafer, Rhizotroqus majalis; Green June beetle, Cotinis nitida; May or June beetle, Phyllophaga spp.; Japanese beetle, Popillia japonica; Oriental beetle, Anomala orientalis; Billbugs, Spherophorus spp.; Annual bluegrass weevil, Hyperodes spp.; Black turfgrass ataenius, Ataenius spretulus and Aphodius spp. and mole crickets, Scapteriscus spp. MARATHON II can also be used for suppression of cutworms and chinchbugs.
For optimum control, make applications preceding or during the egg laying period of the target pest. The active ingredient in MARATHON II has enough residual activity so that applications can be made preceding the egg laying activity. Application timing can be based on historical monitoring of the site, previous records or experiences, current season adult trapping or other methods. Most favorable control will be achieved when applications are made prior to egg hatch of the target pests, followed by sufficient irrigation or rainfall to move the active ingredient through the thatch.
Do not make applications when grassy areas are waterlogged or the soil is saturated with water. Sufficient distribution of the active ingredient cannot be achieved under these conditions. The treated grassy area must be in such a condition that the rainfall or irrigation will penetrate vertically in the soil profile.
Application cannot exceed a total of 1.6 pints (0.4 lb of active ingredient) per acre per year.
Application Equipment for Use on Grassy Areas in Nurseries
Apply MARATHON II in enough water to provide sufficient distribution in the treated area. Use accurately calibrated equipment typically used for the application of soil insecticides which will produce a uniform, coarse droplet spray, using a low pressure setting to eliminate off-target drift. Check calibration periodically to ensure that equipment is working properly.
