First Aid

If swallowed: Immediately call poison control center or doctor. Do not induce vomiting unless told to do so by poison control center or doctor. Do not give any liquid to the person. Do not give anything by mouth to an unconscious person.

If in eyes: Hold eye open and rinse slowly and gently with water for 15-20 minutes. Remove contact lenses, if present, after the first 5 minutes, then continue rinsing eye. Call a poison control center or doctor for treatment advice.

If on skin or clothing: Take off contaminated clothing. Rinse skin immediately with plenty of water for 15-20 minutes. Call a poison control center or doctor for treatment advice.

If inhaled: Move person to fresh air. If person is not breathing, call 911 or ambulance, then give artificial respiration, preferably mouth-to-mouth if possible. Call a poison control center or doctor for further treatment.

Note To Physician

POISONING SYMPTOMS: Symptoms include weakness, headache, tightness in chest, blurred vision, non-reactive, pin-point pupils, salivation, sweating, nausea, vomiting, diarrhea and abdominal cramps.

TREATMENT: Atropine is the specific therapeutic antagonist of choice against parasympathetic nervous stimulation. If there are signs of parasympathetic stimulation, Atropine Sulfate should be injected at 10 minute intervals, in doses of 1 to 2 mgs. until complete atropinization has occurred. Pralidoxime chloride (2-PAM) may also be used as an effective antidote in addition to and while maintaining full atropinization. In adults, initial dose of 1 gram of 2-PAM should be injected, preferably as an infusion in 250 cc of saline over a 15 to 30 minute period. If this is not practical, 2-PAM may be administered slowly by intravenous injection as a 5 percent solution in water over not less than two minutes. After about an hour, a second dose of 1 gram of 2-PAM will be indicated if muscle weakness has not been relieved. For infants and children the dose of 2-PAM is 0.25 gram. Morphine is an improper treatment.

Clear chest by postural drainage. Oxygen administration may be necessary. Observe patient continuously for 48 hours.

Repeated exposure to cholinesterase inhibitors may, without warning, cause prolonged susceptibility to very small doses of any cholinesterase inhibitor. Allow no further exposure until cholinesterase regeneration has been attained, as determined by blood test.

Contains petroleum distillate. Vomiting may cause aspiration pneumonia.

Directions For Use

It is a violation of Federal law to use this product in a manner inconsistent with its labeling.

When properly applied, the repellent effect against above insects will last two days.

For use in areas under general category of farm buildings, (farm yards); dairy and farm premises; feed lots, including around feed lots, stockyards, corrals, holding pens, fences, etc.; animal buildings, including barns, feeding areas, shelters and stables; dairy barns (including milk rooms, equipment and barnyards); and livestock feeding areas.

In a complete fly control program these sprays should be used in combination with residual insecticides and sanitary measures.

To develop a residual repellency to stable flies, mosquitoes and gnats on dairy cows, apply 1 to 2 ounces of PROZAP DAIRY CATTLE SPRAY to each animal for a three day period. The spray should be applied with a good hydraulic-type hand sprayer so that the animal’s entire body has been uniformly covered. Special care should be used in spraying the legs, belly and shoulders. Avoid areas around the nose, eyes and mouth. Avoid wetting the hide. Do not make direct application to livestock more frequently than once per day. Spray in the same manner again after two days have elapsed and every second day thereafter or when insects again disturb the animal. Be sure the teats and udder are washed with warm water prior to milking. Calves should be sprayed very lightly once a day instead of attempting to build up a residual repellence by spraying more heavily. Brahman and Brahman cross cattle should not be treated as they may show hypersensitivity to organic phosphates.

For control of lice on livestock, spray the animals with 2 ounces of PROZAP DAIRY CATTLE SPRAY. Immediately rub the spray into the hair (do not use bare hand), paying particular attention to infested areas. Repeat as necessary, but not more frequently than once every three weeks.

To kill flies, mosquitoes and gnats in the barn prior to milking, close all doors and windows and direct the spray towards the ceiling. The barn should remain closed for 10 to 20 minutes. Sweep up and destroy fallen insects. Repeat as necessary, but no more than once per day. Apply at the rate of one ounce spray per 1,000 cubic feet. Do not remain in the treated areas and ventilate the area after treatment is complete. Do not use this solution for fogging or misting in areas where animals have received direct application of dichlorvos or other organophosphate within 8 hours. Do not contaminate water, feed or foodstuffs, milk or milking utensils. Avoid over spraying which will result in wetting the animal’s hides. Avoid contamination of milk and milk handling equipment.
