Overall review Flashcards
How do fungi reproduce?
Fungi reproduce asexually by fragmentation, budding, or producing spores. Fragments of hyphae can grow new colonies. Mycelial fragmentation occurs when a fungal mycelium separates into pieces with each component growing into a separate mycelium. Somatic cells in yeast form buds.

What factors increase drift?
- Wind speed. Wind speed and wind direction are the No. 1 factor to influence drift, over and above everything else.
- Boom height. You might think that boom height would only influence drift in small ways. …
- Distance from the susceptible crop. Drift isn’t a concern in the target crop. …
- Spray particle size.
What factors increase leaching?
- Particle size.
- Temperature.
- Concentration of reagent.
- Stirring/Agitation rate.

Who can spray restricted use pesticides?
Restricted use pesticides or “RUP” are pesticides not available to the general public in the United States. The “Restricted Use” classification restricts a product, or its uses, to use by a certificated pesticide applicator or under the direct supervision of a certified applicator. This means that a license is required to purchase and apply the product.
Which formulation is most absorbed through skin?
Emulsifiable Concentrates (E or EC)
What is a wetable powder?
Wettable Powders (WP or W) Wettable powders are dry, finely ground solid materials. Most include wetting and/or dispersing agents. Usually, they must be mixed with water and applied as a spray. A few products, however, may be applied dry or as a liquid suspension. Wettable powders contain 5% to 95% active ingredient—usually 50% or more. Wettable powder particles do not dissolve in water. When mixed with water, they form a suspension. They will settle out quickly without constant agitation to keep them suspended. To prepare a spray suspension, you must form a slurry. Mix a WP with a small amount of water, and then dilute this slurry mixture further. Wettable powders are effective for most pest problems and in most types of spray equipment where agitation is possible. They have excellent residual activity and do not usually harm treated surfaces. When you apply a WP spray suspension to a target, most of the pesticide remains on the surface. This is true even for porous materials, such as concrete, plaster, and untreated wood. In such cases, only the water carrier penetrates the porous material. Wettable powder particles remain on the treated surface.
Who do you report spills to?
Who regulates/requires respirators?
NIOSH
Who regulates transportation of pesticides?
Who regulates pesticides applied to agriculture?

Who regulates pesticides treated for aquatic pests?
Department of Ecology
