What are some Pros for Dust (DU) pesticides.
Consists of a active ingredient diluted with powedered material
Spot treatment to control insects and deases on plants. Insect conttrol on animals. Seed treatment. insect control in enclosed areas of building.
It is ready to use.
What are some Cons for Dust (DU) pesticides.
Consists of a active ingredient diluted with powedered material
Spot treatment to control insects and deases on plants. Insect conttrol on animals. Seed treatment. insect control in enclosed areas of building.
Drifts away from target, visible residue, and easily inhaled.
What are some Pros to Granule (GR) pesticides.
Controls insects, desease and weeds, with different treatments.
Mixture of large, free flowing partlicles with a low concentration of active ingredient
It is ready to use, no mixing required, There is little danger to drift.
What are some Cons to Granule (GR) pesticides.
Controls insects, desease and weeds, with different treatments.
Mixture of large, free flowing partlicles with a low concentration of active ingredient
Possible to inhale associated dust, and may be eaten by birds.
What are some Pros to Soluble Granules (SG) pesticides.
Weed control
Similar in appearance to a granular formulation but the particles are dissolved in water before application.
Reasonably safe to handle. There is little danger of exposure through eyes, skin or inhaling.
What are some Cons to Soluble Granules (SG) pesticides.
Weed control
Similar in appearance to a granular formulation but the particles are dissolved in water before application.
Mixing is required.
What are some Pros to Wettable Powder (WP) pesticides.
Sprays for insect, weed and disease control.
A dry powder material made of an active ingredient, a wetting agent and other formulants. It is mixed with water to form a suspension. In a suspension the particles of the active ingredient are not dissolved.
It is easy to store in un heated locations. Slower absorption by skin than with emulsion. More cost effective than liquid formation.
What are some Cons to Wettable Powder (WP) pesticides.
Sprays for insect, weed and disease control.
A dry powder material made of an active ingredient, a wetting agent and other formulants. It is mixed with water to form a suspension. In a suspension the particles of the active ingredient are not dissolved.
High risk of exposure through skin, eyes and inhaling. Requires constant agitation. abrasive to equiment, and may leave a visible residue.
What are some Pros to Wettable Granule (WG) or Dry Flowable (DF)
Most are sprays foor weed control. Some or for insect control.
Consists of small granules or spheres that break down into wettable powders
Less dusty than wetable powders so less chance of exposure.
What are some Cons to Wettable Granule (WG) or Dry Flowable (DF)
Most are sprays foor weed control. Some or for insect control.
Consists of small granules or spheres that break down into wettable powders. in suspension.
Requires constant agitation, abrasive to equipment, and may leave visable residue.
What are some Pros to Bait pesticides.
Used to control slugs, rodents and certain insects.
Consists of an active ingredient mixed with substances to attract pests such as food or edible substances.
Can be target specific with minimal risk to non targets. Most are ready to use.
What are some Cons to Bait pesticides.
Used to control slugs, rodents and certain insects.
Consists of an active ingredient mixed with substances to attract pests such as food or edible substances.
Could be eaten by pets, wildlife or children. Safe use may require the use of tamper-resistant bait station.
What are some Pros to Tablet Pesticides
Pesticides formulated into pre-measured ‘doses’ of dry material.
Some are meant to be mixed with water and sprayed (a certain number of tablets in a certain volume of water), some are meant to be used ‘as is’ (e.g., some fumigants are applied as tablets to stored grain. the tablets give off toxic gas when exposed to air and kills insects in the grain).
Ease of measuring, and easy to handle.
What are some Cons to Tablet Pesticides
Pesticides formulated into pre-measured ‘doses’ of dry material.
Some are meant to be mixed with water and sprayed (a certain number of tablets in a certain volume of water), some are meant to be used ‘as is’ (e.g., some fumigants are applied as tablets to stored grain. the tablets give off toxic gas when exposed to air and kills insects in the grain).
They may not mix quickly with water, and they could be attractive to, and ingested by children and animals.
What are some Pros for Fumigant Pesticides.
Work as gases during application to control pests.
Pressurized liquids, pressurized gases or solids such as tablets or pellets that produc gases when exposed to air or water.
Penetrates hard to reach areas (e.g., grain bins, flour mills, bags of products in warehouses). Toxic to all pests in a enclosed area so one application will control heavy infestations.
What are some Cons for Fumigant Pesticides.
Work as gases during application to control pests.
Pressurized liquids, pressurized gases or solids such as tablets or pellets that produc gases when exposed to air or water.
Extremely toxic so there is a very high risk of respiratory exposure. Specialized personal protective equipment required for all applicators and assistants. Buildings and soil need to be prepared and sealed prior to, or immediately after, application. Can react with some metals and wiring in buildings. Damages and kills non-target organisms.
What are some Pros with Pressurized Product (PP) pesticides
Areosol spray, foam or dust packed in a pressurized container.
These particles are applied straight from their containers into the air, onto surfaces or into cracks and crevices, depending on the product. Most are used to control or repel pests
Ready to use, and portable.
What are some Cons with Pressurized Product (PP) pesticides.
What are some Pros with Pressurized Product (PP) pesticides
These particles are applied straight from their containers into the air, onto surfaces or into cracks and crevices, depending on the product. Most are used to control or repel pests
Risk of inhalation, and may be difficult to cofine to target area.
What are some Pros to Soluble Powder (SP) pesticides.
Sprays for insect or weed control, or deer repellent.
Consists of powder active ingredients and inert material that is dissolved in water.
Cost effective, and containers empty easily. After mixing, no agitation needed.
What are some Cons to Soluble Powder (SP) pesticides.
Sprays for insect or weed control, or deer repellent.
Consists of powder active ingredients and inert material that is dissolved in water.
If inhaled as powder, it can be hazerdous to health of applicator. Risk of exposure through skin or eyes when mixing.
