Drift and runoff may be hazardous to aquatic organisms in water adjacent to treated areas. Use care when applying in or to an area which is adjacent to any body of water, and do not apply when weather conditions favor drift from target area. Poorly draining soils and soils with shallow water tables are more prone to produce runoff that contains this product. Reporting Ecological Incidents: To report ecological incidents, including mortality, injury, or harm to plants and animals, call (901) 774-4370. When applying as a wide area mosquito adulticide, before making the first application in a season, it is advisable to consult with the State or Tribal agency charged with primary responsibility for pesticide regulation to determine if other regulatory requirements exist. This product is highly toxic to bees exposed to direct treatment on blooming crops or weeds. Do not apply or allow to drift onto blooming crops or weeds while bees ar e actively visiting the treatment area, except when applications are made to prevent or control a threat to public and/or animal health determined by a State, Tribal or local public health or vector control agency on the bas is of documented evidence of disease causing agents in vector mosquitoes or the occurrence of mosquito- borne disease in animal or human populations, or if specifically approved by the State or Tribe during a natural disaster recove ry effort. When applying as a wide area mosquito adulticide, do not apply over bodies of water (lakes, rivers, permanent streams, natural ponds, commercial fish ponds, swamps, marshes or estuaries), e xcept when necessary to target areas where adult mosquitoes are present, and weather conditions will facilitate movement of applied material away from the water in order to minimize incidental deposition into the water body. Do not discharge effluent containing this product into lakes, streams, ponds, estuaries, oceans, or other waters unless in accordance with the requirements of a National Pollutant Discharge Elimination System (NPDES) permit and the permitting authority has been notified in writ ing prior to discharge. Do not discharge effluent containing this product to sewer systems without previously notifying the local sewage treatment plant authority. For guidance contact your State Water Board or Regional Office of the EPA. PHYSICAL OR CHEMICAL HAZARDS Do not use or store near heat or open flame.

This timing restriction prohibits applications when bees are most active (mid-day). This restriction does not apply when applications are made as a spot treatment or to prevent or control a threat to public and/or animal health determined be a state, tribal or local public health or vector control agency on the basis of documented evidence of disease causing agents in vector mosquitoes or the occurrence of mosquito borne disease in animal and human populations, or if specifically approved by the state or tribe during a natural disaster recovery effort. Calibrate and inspect nozzles at least once a year to ensure they are in good working condition. Mandatory spray Drift Management Ultra Low Volume Applications x Apply when ground wind speeds are equal to or greater than 1 mph. x All types of applications should be conducted when temperatures at ground level are at or above 50°F. For Ground Applications: x Create an optimum swath when possible. An optimum swath width can be achieved when this product is applied from a truck that is being driven perpendicular to the wind direction. Direct the spray head of equipment to ensure even distribution of the spray cloud throughout the area. x FOR BEST RESULTS treat when mosquitoes or insects are most active and weather conditions are conducive to keeping the spray cloud in the air column close to the ground. x An inversion of air temperatures and a light breeze is preferable. Application during the cooler hours of the night or early morning is recommended. For Aerial Applications:

Page 4 of 7

x Do not apply by fixed wing aircraft at a nozzle height less than 100 feet (30.5 m) above ground or canopy, or by helicopter at a height less than 75 feed (22.9 m) above the ground or canopy, unless specifically approved by the state or tribe based on public health needs. Adult mosquito control applications should be limited to trained personnel. x For use only by federal, state, tribal or local government officials responsible for public health or vector control or by persons certified in the appropriate category or otherwise authorized by the state or tribal lead pesticide regulatory Agency to perform adult mosquito control applications, or by persons under their supervision, or as allowed by state regulations for persons treating private property. x This pesticide is toxic to aquatic organisms. Runoff from treated areas or deposition of spray droplets into a body of water may be hazardous to aquatic organisms. x Do not apply over bodies of water (lakes, rivers, permanent streams, natural ponds, commercial fish ponds, swamps, marshes or estuaries), except when necessary to target areas where adult mosquitos are present, and weather conditions will facilitate movement of applied material beyond the body of water to minimize incidental deposition into the water body. Do not contaminate bodies of water when disposing of equipment rinsate or wash waters. x Before making the first application in a season, consult with the state or tribal Agency with primary responsibility for pesticide regulation to determine if other regulatory requirements exist. x Treatment of a site must be based on surveillance results. Do not treat any site with malathion more than 1 time per day. Do not apply more than 0.23 lbs ai/acre of this product per day by air or 0.06 lbs ai/acre per day by ground within any 24-hour period. Do not treat any site with more than 0.46 lb ai/acre within a 7 day period and the amount of undiluted product applied to any site must not exceed 5.75 lbs ai/acre per year. More frequent treatments may be made to prevent or control a threat to public and/or animal health determined by a state, tribal or local health or vector control agency on the basis of documented evidence of disease causing agents in vector mosquitoes or the occurrence of mosquito- borne disease in animal or human populations, or if specifically approved by the state of tribe during a natural disaster effort. RESISTANCE MANAGEMENT RECOMMENDATIONS For resistance management, MALATHION ULV 96.5% contains a Group 1B insecticide or acaricide. Any insect/mite population may contain individuals naturally resistant to this product and other Group 1B insecticides/acaricides. The resistant individuals may dominate the insect/mite population if this group of insecticides/acaricides are used repeatedly in the same fields. Appropriate resistance-management strategies should be followed. To delay insecticide/acaricide resistance, take the following steps: x Rotate the use of this product or other Group 1B insecticides/acaricides within a growing season, or among growing seasons, with different groups that control the same pests. x Use tank mixtures with insecticides/acaricides from a different group that are equally effective on the target pest when such use is permitted. Do not rely on the same mixture repeatedly for the same pest population. Consider any known cross-resistance issues for the targeted pests between the individual components of a mixture. In addition, consider the following recommendations provided by the Insecticide Resistance Action Committee (IRAC): MALATHION GROUP 1B INSECTICIDE

Page 5 of 7

o Individual insecticides selected for use in mixtures should be highly effective and be applied at the rates at which they are individually registered for use against the target species. o Mixtures with components having the same IRAC mode of action classification are not recommended for insect resistance management. o When using mixtures, consider any known cross-resistance issues between the individual components for the targeted pest(s). o Mixtures become less effective if resistance is already developing to one or both active ingredients, but they may still provide pest management benefits. o The insect resistance management benefits of an insecticide mixture are greatest of the two components have similar periods of residual insecticidal activity. Mixtures of insecticides with unequal periods of residual insecticide activity may offer an insect resistance management benefit only for the period where both insecticides are active. x Adopt an integrated pest management program for insecticides/acaricides use that includes scouting, uses historical information related to pesticide use, crop rotation, record keeping, and which considers cultural, biological and other chemical control practices. x Monitor after application for unexpected target pest survival. If the level of survival suggests the presence of resistance, consult with your local university specialist or certified pest control advisor. x Contact your local extension specialist or certified crop advisor for any additional pesticide resistance-management and/or IPM recommendations for the specific site and pest problems in your area. x For further information or to report suspected resistance contact Drexel Chemical Company at 1- 901-774-4370. MOSQUITO CONTROL IN POPULATED AND RURAL AREAS PRECAUTIONS AND RESTRICTIONS Before making the first application in a season, it is advisable to consult with the State or Tribal agency with primary responsibility for pesticide regulation to determine if other regulatory requirements exist. Restrictions: • Do not apply more than 0.23 pound a.i. per acre per day. • Only treat when mosquitoes are swar ming or biting. Do not retreat a site more than 3 times in any one week. However, more frequent treatments may be made to prevent or control a threat to public and/or animal health determined by a State, Tribal or local health or vector control agency on the basis of documented evidence of disease causing agents in vector mosquitoes or the occurrence of mosquito-borne diseases in animal or human populations, or if specifically approved by the State or Tribe during a natural disaster effort. • Apply when wind speed is greater than or equal to 1 mph. • Do not apply by fixed wing aircraft at height less than 100 feet, or by helicopter at a height less than 75 feet unless specifically approved by the State or Tribe based on public health needs. Precautions: • IMPORTANT: IN AREAS WHERE AUTOMOBI LES, TRAILERS, TRUCKS AND PLEASURE BOATS ARE PRESENT, undiluted spray droplets of this product will permanently damage vehicle paint finishes unless the aircraft used for the ultra low volume application meets all of the specifications listed under AERIAL APPLICATION. AERIAL APPLICATION Adult Mosquitoes on Rangeland, P asture, and Other Uncultivated No n-Agricultural Areas (Wastelands, Roadsides): Spray equipment must be adjusted so that the volume me dian diameter produced is less than 60 microns (Dv 0.5 < 60 um) and that 90% of the spray is contained in droplets smaller than 100 microns (Dv 0.9 < 100 um). The effects of flight speed and, for non-rotary nozzles, nozzle angle on the droplet size spectrum must be considered. Directions from the equipment manufactur er or vendor, pesticide reg istrant or a test facility using a wind tunnel and laser-based measurement instrument must be used to adjust equipment to produce acceptable droplet size spectra. Application equipment must be tested at least annually to confirm that pressure at the nozzle and nozzle flow rate(s) are properly calibrated.

Adult mosquito control over cities, towns, and othe r areas where automobiles, trailers, trucks, and pleasure boats are present: Apply 2.6 to 3.0 fluid ounces of this product per acre. Apply only when weather conditions are favorable. Wind and rising air currents may cause undesirable spray drift and reduce insect control. See "Precautions and Restrictions" for additional instructions. BUFFER ZONES FOR AERIAL APPLICATION Do not apply within 100 feet of aquatic habitats (such as, but not limited to, lakes, reservoirs, rivers, streams, wetlands, ponds, estuaries, and commercial fish ponds). This 100-foot buffer is in addition to the full swath displacement upwind that applicators must use at the downwind edge of the field. Applications made by mosquito control districts and other public health officials are exempt from this requirement. GROUND-BASED APPLICATION Spray equipment must be adjusted so that the volume median diameter is less than 30 microns (Dv 0.3 < 30 um) and that 90% of the spray is contained in droplets smaller than 50 microns (Dv 0.9 < 50 um). Directions from the equipment manufacturer or vendor, pesticide registrant or test facility using laser-based measurement instrument must be used to adjust equipment to produce acceptable droplet size spectra. Application equipment must be tested at least annually to confirm that pressure at the nozzle and nozzle flow rate(s) are properly calibrated. Do not apply within 50 feet of aquatic habitats (such as, but not limited to, lakes, reservoirs, rivers, streams, wetlands, ponds, estuaries, and commercial fish ponds). This 50-foot buff er is in addition to the full swath displacement upwind that applicators must use at the downwind edge of the field. Applications made by mosquito control districts and other public health officials are exempt from this requirement. Thermal Aerosols or Fogs For control of adult mosquitoes with thermal aerosols or fogs: Apply this product at the rate of 3.9 to 5.2 gallons of this product in 100 gallons of finished solution by ground equipment delivering 40 gallons per hour at a vehicle speed of 5 miles per hour to treat a swath width of 300 fe et (equivalent to 180 acres per hour). At 3.9 gallons of this product per 100 gallons of finished solution, this is equivalent to 0.08 pounds active per acre. At 5.2 gallons per 100 gallons of finished solution, this is equivalent to 0.11 pound active per acre. Non-thermal Aerosols Adult Mosquito Control - Control of adult mosquitoes over a 300-foot swath can be obtained with non-thermal aerosols of this product using the following rates at the indicated vehicle speeds: Rates for This Product Undiluted Apply As Follows: Pounds A.I. per Acre per Day Application Rates Fluid Ounces per Minute at Vehicle Speed Fluid Ounces of This Product per Acre5 mph 10 mph 15 mph 20 mph 0.03 to 0.06* 1.0 to 2.1 2.0 to 4.3 3.0 to 6.3 4.0 to 8.6 0.38 to 0.75 *Use higher rate of application when vegetation is dense and/or mosquito populations are heavy. OPERATING EQUIPMENT Each non-thermal aerosol generator used for dispersal of this product to control adult mosquitoes must have minimum capability of producing the droplet spectrum described under GROUND BASED APPLICATION. The initial determination of droplet size is made after the unit is installed in a vehicle and prior to its use in mosquito control operations. Recheck the unit frequently to insure that proper droplet size is maintained for each operation. Determination of droplet size every two months is usuall y sufficient if the unit has been maintained in good operating condition. Equipment manufacturer's instructions setting forth cleaning and maintenance of the unit must be followed. The unit must be inspected before each op eration to correct any leaks or obstructions in the spray system; to detect whether the nozzle, hoses, or other parts are worn and need replacement; to insure that the flow meter is properly calibrated and to determine that the pressure recommended by the manufacturer is being maintained. Flow Rate - Must be regulated by accurate flow meter
