General Information


SEVIN brand XLR PLUS Carbaryl Insecticide is a suspension of microfine SEVIN brand carbaryl insecticide in an aqueous medium. It readily disperses in water to form a spray which may be applied by air or ground.


Application to wet foliage or during periods of high humidity may cause injury to tender foliage. Do not use on Boston Ivy, Virginia creeper and maidenhair fern as injury may result. Carbaryl may also injure Virginia and sand pines. The use of adjuvants may increase the potential for crop injury to sensitive crops.


For all listed crops and uses, do not apply at greater rates or at more frequent intervals than stated on the label. If forage is grazed or used as feed for dairy and meat animals, follow all use restrictions in order to avoid illegal residues in crops, meat or milk. Do not use reclaimed irrigation water from crops treated with carbaryl on crops for which carbaryl tolerances are not established.


Calibrate and adjust application equipment to insure proper rate and accurate placement. To clean spray system after use, drain and flush with a water and detergent mixture. Rinse thoroughly with clean water. Refer to the Storage and Disposal section for disposal instructions.

NOTE: Staining may occur on certain surfaces such as stucco, brick, cinder block, and wood. Spray deposits on painted or stained surfaces or finishes (i.e., cars, houses, trailers, boats, etc.) should be immediately removed by washing to prevent discoloration. Avoid applications to surfaces where visible spray residues are objectionable. For outdoor use only.


All references to armyworm on the crops listed below refer to the species, Pseudaletia unipuncta, often called the “true armyworm”. Except where indicated otherwise, this product is not registered for other armyworm species. Regional differences have been noted in the susceptibility of certain strains of fall armyworm, diamondback moth, Colorado potato beetle and Southern green stink bug to carbaryl. If local experience indicates inadequate product performance, use an alternative pesticide.


SEVIN brand XLR PLUS Carbaryl Insecticide, when diluted with at least an equal volume of water, is compatible with a wide range of pesticides. It is not compatible with diesel fuel, kerosene, fuel oil or aromatic solvents. If compatibility with another product and the resulting crop response is unknown, the mixture should be tested on a small scale. Curdling, precipitation, greasing, layer formation or increased viscosity are symptoms of incompatibility. Incompatibility will reduce product performance and may cause application and handling difficulties or plant injury. Observe all cautions and limitations on labeling of all products used in mixtures. WHEN PREPARING COMBINATION SPRAYS, FIRST ADD SEVIN BRAND XLR PLUS CARBARYL INSECTICIDE TO AT LEAST AN EQUAL VOLUME OF WATER, MIX THOROUGHLY, AND THEN ADD COMBINATION PRODUCTS TO THE MIXTURE. DO NOT APPLY TANK MIX COMBINATIONS UNLESS YOUR PREVIOUS EXPERIENCE INDICATES THE MIXTURE IS EFFECTIVE AND WILL NOT RESULT IN APPLICATION PROBLEMS OR PLANT INJURY.

Carbaryl is unstable under highly alkaline conditions and mixtures with strong bases, such as Bordeaux, lime-sulfur and casein-lime spreaders, will result in chemical degradation of the insecticide. Do not use this product in water with pH values above 8.0 unless a buffer is added. If necessary, water should be buffered to neutral (pH = 7.0) before adding this product to the spray tank. Overhead irrigation with alkaline or muddy water after application will also accelerate chemical degradation and may result in reduced product performance.


On all crops use sufficient gallonage to obtain thorough and uniform coverage. Observe crop label instructions for specific directions regarding spray volume where they occur. Calibrate spray equipment to deliver the required volume. The flow rate of this product diluted 1:1 with water is similar to water. Use of 50 mesh slotted strainers in spray system and 25 mesh slotted strainers behind nozzles is recommended.


Dilution of 1 volume of SEVIN brand XLR PLUS Carbaryl Insecticide with 1 volume of water provided maximum resistance to washoff by rainfall or overhead irrigation. Dilutions higher than 1 part SEVIN brand XLR PLUS Carbaryl Insecticide to 39 parts water (1:39) are not recommended when washoff resistance is desired.

To achieve washoff resistance, SEVIN brand XLR PLUS Carbaryl Insecticide must be diluted as stated above, and droplets must dry on the foliage. When atmospheric humidity is low, a drying time of at least two hours is generally adequate. Under high humidity a longer drying time is required. Washoff resistance cannot be expected if this product is applied to wet foliage and has not thoroughly dried prior to rainfall or overhead irrigation.

On all crops, use sufficient spray volume to obtain thorough coverage. The best product performance under certain crop, pest or climatic conditions may require spray gallonages higher than the 1:39 dilution. For example, in hot, arid weather (low humidity), higher spray gallonage per acre may be required to compensate for loss from evaporation and insure thorough coverage. The total spray volume required for effective product performance can best be determined by previous experience, pest and crop conditions and local recommendations.


Apply in sufficient volume for adequate coverage on all crops and sites.


For adequate distribution, use at least 10 gallons of spray mixture per acre for application for tree and orchard crops or at least 2 gallons of spray mixture per acre for application to other crops. EXCEPTION: For the use of SEVIN brand XLR Plus Carbaryl Insecticide on rangeland as a pest management approach for grasshoppers under the Reduced Area and Agent Treatments (RAATs) program only, use at least 16 ounces of finished spray mixture per acre for aerial application.


Begin application when insect populations reach recognized economic threshold levels. Consult the Cooperative Extension Service, Consultants, or other qualified authorities to determine appropriate threshold levels and timing for treatment in your area. Where a dosage range is indicated, use the lower rate on light to moderate infestations, young plants and early instars and use the higher rate on heavy infestations, mature plants, advanced instars and adults. Thorough and uniform spray coverage is essential for effective product performance.


The RAATs approach takes advantage of grasshopper movement to allow SEVIN brand XLR Plus Carbaryl Insecticide to be applied at reduced rates on a reduced treated area while maintaining acceptable protection against grasshopper. Under this program, SEVIN brand XLR Plus Carbaryl Insecticide may be applied to as little as 50% of the infested area (treating a 100 ft swath, skipping a 100 ft swath), up to 100% of infested area. The amount of area treated will depend on grasshopper age, density and plant canopy. By leaving untreated swaths, the RAATs program provides reserves for natural biological control agents. This strategy fully utilizes an Integrated Pest Management approach for grasshopper.

Apply 8 ounces to 16 ounces by air or ground on 50 – 100% of infested area for grasshopper nymphs between the 2nd and 5th instar. The rate to use per acre will depend on grasshopper age, population density and plant canopy.

Use the higher rates on more mature grasshoppers, severe infestations and dense vegetation. Use the lower rates on younger grasshoppers, light to moderate infestations and sparse vegetation. Consult with the local grasshopper control experts in your area for the proper rate and swath width to use under your conditions.

Computer software packages such as HOPPER (USDA) and CARMA (University of Wyoming) are available to assist in grasshopper management decisions.

The best spray gallonage will depend on the plant canopy (foliage density), air temperature and wind speed.

Under favorable application conditions (sparse vegetation, low air temperatures and 0 – 5 mph wind speed), use 16 ounces to 2 gallons of finished spray per acre. This product cannot be applied in a concentration greater than 1 part SEVIN brand XLR PLUS Carbaryl Insecticide to 1 part water. Under adverse conditions (dense vegetation, high temperatures and low humidity) higher spray gallonage per acre may be required to compensate for loss from evaporation and ensure thorough coverage.

NOTE: The use of SEVIN brand XLR Plus Carbaryl Insecticide under the RAATs program is meant to provide ranchers with an economic and environmentally sound means to reduce grasshopper competition on their rangeland. RAATs program results indicate that this reduction in grasshopper competition for range forage provides economic protection against most species under most conditions. However, if a higher level of protection is required, refer to the SEVIN brand XLR PLUS Carbaryl Insecticide label for specific recommendations.
