Are Shipboard Pesticides
A substance used to control mites, scorpions, spiders, ticks and related organisms
Acaricides
Used to control the adult stage of an insect
Adulticide
Used to control the larval stage of an insect.
Larvicide
Used against the egg stage of an insect.
Ovicide
Used to control rodents.
Rodenticide
Are compounds of mineral origin and mainly include arsenic, copper, mercury, sulfur or zinc
Inorganic pesticides
Are a group of synthetic organic compounds with one or more chlorine atoms. Chlordane, dieldrin, and DDT are examples
Chlorinated hydrocarbons
Synthetic compounds containing phosphorous
Organophosphates
Are synthetic compounds of salts or esters of carbamic acid. Carbaryl and propoxur are examples
Carbamates
Are pesticides of plant origin. Pyrethrums and rotenone are examples.
Botanical
They are effective for penetrating cracks and crevices. They may be used around electrical equipment or power
Oil Solutions
Consists of droplets of an emulsifiable pesticide dispersed in a diluent in such\na way as to prevent separation of the two components
Emulsions
Are preparations of pesticide impregnated into particles of highly\nabsorptive clays and earths which are graded by sizes ranging from coarse pebble–like pellets to those with a consistency of fine sand
Granules/Pellets
This miscellaneous grouping includes the application of pesticides by brush or roller, as a paste, grease, or cream, or as solid formulations which vaporize slowly in air.
Nonparticle pesticides.
Are materials that enhance the effectiveness of basic toxicant chemicals by altering their physical or chemical characteristics
Additives
Used only in airtight spaces which prevent dissipation
Gases and Vapors
Suspension of liquid or solid particles in air
Aerosols
Are dispersed particles in which the particles are intermediate in size
Mists
Spray droplets are considered to be from 100 to 400 microns in diameter
Fine Sprays
Consist of droplets over 400 microns in diameter
Coarse Sprays
What is Highly Toxic? (How much does it take to administer death)
0–50 mg/kg
What is Moderately Toxic? (How much does it take to administer death)
50–500 mg/kg
