DIRECTIONS FOR USE
It is a violation of Federal Law to use this product in a manner inconsistent with its labeling. Read all directions for use carefully before applying. This product is for use in commercial settings only. Use in residential settings is prohibited.
Do not apply this product 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.

CHEMIGATION PROHIBITION
Do not apply this product through any type of irrigation system.

DIRECTIONS
This product is an insecticide used to control aphids, leafhoppers, leafminers, pear psylla, and mites(except rust mites) as specified in this labeling.
Do not apply when weather conditions favor drift of spray from areas treated. Spray drift may result in injury to non target crops or vegetation. To avoid spray drift, do not apply when wind speed is greater than 10 MPH or during periods of temperature inversion. Do not apply when weather conditions, wind speed, or wind direction may cause spray drift to non-target areas. AVOIDING SPRAY DRIFT AT THE APPLICATION SITE IS THE RESPONSIBILITY OF THE APPLICATOR. See Requirements for Reducing Spray Drift section for further information.
FOR AERIAL OR GROUND APPLICATION by commercial growers or commercial applicators, on the crops listed below, apply specified amounts in sufficient water for good coverage.
FOR AERIAL APPLICATION use the specified amount of Dimethoate 25WP in 2 to 10 gallons of water. High Pressure Handwand Equipment: When application is made by high pressure handwand equipment, the maximum application rate for all crops and use patterns is 0.0025 pounds active ingredient per gallon. Requirements for Reducing Spray Drift:
Do not apply under circumstances where possible drift to unprotected. persons or to food, forage, or other plantings that might be damaged or crops thereof rendered unfit for sale, use, or consumption can occur.
1. Use the largest droplet size consistent with acceptable efficacy. Formation of very small droplets may be minimized by appropriate nozzle selection, by orienting nozzles away from the air stream as much as possible, and by avoiding excessive spray boom pressure. For groundboom and aerial applications, use medium or
coarser spray nozzles according to ASAE 572 definition for standard nozzles or a volume mean diameter (VMD) of 300 microns or greater for spinning atomizer nozzles.
2. Make aerial or ground applications when the wind velocity favors on-target product deposition. Apply only when the wind speed is less than or equal to 10 mph. For all non-aerial applications, wind speed must be measured adjacent to the application site on the upwind side, immediately prior to application.
3. Do not make aerial or ground applications into areas of temperature inversions. Inversions are characterized by stable air and increasing temperatures with increasing distance above the ground. Mist or fog may indicate the presence of an inversion in humid areas. Where permissible by local regulations, the applicator
may detect the presence of an inversion by producing smoke and observing a smoke layer near the ground surface.
4. Low humidity and high temperatures increase the evaporation rate of spray droplets and therefore the likelihood of increased spray drift. Avoid spraying during conditions of low humidity and/or high temperatures.
5. All aerial and ground. application equipment must be properly maintained and calibrated using appropriate carriers.
6. For groundboom applications, apply with nozzle height no more than 4 feet above the ground or crop canopy.
7. For airblast applications, turn off outward pointing nozzles at row ends and when spraying the outer two rows. To minimize spray loss over the top in orchard applications, spray must be directed into the canopy.
8. For aerial applications, release spray at the lowest height consistent with efficacy and flight safety. If the application includes an aquatic buffer zone, do not release spray at height greater than 10 feet above the ground or crop canopy.
9. For aerial applications, mount the spray boom on the aircraft so as to minimize drift caused by wing tip vortices. The minimum practical boom length should be used and must not exceed 75% of the wingspan of 90% of rotor blade diameter. Use upwind swath displacement.

Resistance Management
Dimethoate 25 WP contains a Group 1 B insecticide/miticide. InsecUmite biotypes with acquired resistance to Group 1 B may eventually dominate the insecUmite population if Group 1 B insecticides/miticides are used repeatedly in the same field or in successive years as the primary method of control for targeted species. This may result in partial or total loss of control of those species by Dimethoate 25 WP or other Group 1 B.
Contact your local extension specialist, certified crop advisors, and or manufacturer for insecticide resistance management and or IPM recommendations for the specific site and resistant pest problems. To delay insecticide resistance in insects that are at risk of developing resistance to insecticides consider:
• Avoid the consecutive use insecticides on the same insect species.
• Use tank-mixtures or pre-mixes of insecticides from a different target site of action.
• Base insecticide use on a comprehensive IPM program.
• Monitor treated insect populations for loss of field efficacy.
• Contact your State Agricultural Experiment Station, State Extension Specialists, other turf experts and/or Arysta LifeScience North America Corporation for insecticide resistance management and/or IPM recommendations for the specific site and resistant pest problems.
• For further information or to report suspected resistance, you may contact Arysta LifeScience North America Corporation at 1-866-761-9397.
