Active ingredient
|
Chemical in pesticide product that controls target pest and has toxicity
|
|
|
Calibration
|
Measurement and adjustment of your application equipment to ensure that it is delivering the proper amount of pesticide
|
|
|
Concentrated
|
Having a high percentage of active ingredient
|
|
|
Diluent
|
Anything used to dilute pesticide
|
|
|
Dilute
|
To make less concentrated
|
|
|
Formulation
|
Pesticide product as sold, usually a mixture of active and inert ingredients
|
|
|
Tip-and-pour
|
Built-in measuring device that fills with a given amount
of pesticide when the container is tilted |
|
|
Why is it so important to apply the correct amount of pesticide to the target site?
|
If you apply too little, you may not fully control the pest.
Overdosing may cause damage or injury, leave illegal residues, and cause you to be fined or to be liable for damages |
|
|
Where can you find how much pesticide to apply?
|
From the "Directions for Use" section of the labeling, and from other sources such as consultants, industry organizations, specialists, USDA Cooperative Extension agents, university specialists, or pesticide dealers
|
|
|
What are some of the ways that application rates may be stated?
|
1. Amount per unit of area or per unit of volume
(such as pounds or gallons per acre, per square foot, or per cubic foot) 2. Amount per volume of mixture (such as 3 tablespoons of product per five gallons of kerosene or 1-pint per 100-gallons of water) 3. Amount of active ingredient per unit of area or per volume of mixture (such as 1-pint active ingredient per 1,000 square feet, or 0.5 pound active ingredient per 500-gallons of water) 4. Percentage of the final dilution (such as .05% by volume or 1% by weight) |
|
|
Why is it important to calibrate some types of pesticide application equipment?
|
So that the correct amount of pesticide will be released to the target site
|
|
|
How do you calculate the application rate?
|
The amount of pesticide dispersed, divided by the distance of the area covered
|
|
|
Why should you calibrate equipment frequently?
|
Clogging, corrosion, and wear may change the delivery rate, or the settings may gradually get out of adjustment
|
|
|
What pesticide formulations must be diluted before application?
|
Must dilute all except those sold as ready-to-use
or those designed to be applied at full strength |
|
|
What information do you need to get from the pesticide labeling or other souces before you can dilute correctly?
|
1. What to use to dilute
2. How much to dilute 3. How much of the dilute pesticide to apply per unit of area |
|
|
What information do you need to know about your own situation before you can calculate how much pesticide and diluent to combine to achieve the correct amount of dilute mixture in your application equipment?
|
1. How much your equipment holds when full or how much mixture you will need to complete the job
2. How much mixture your equipment applies per unit of area 3. The size of the site you need to treat |
|
|
What is the purpose of a valve?
|
1. Shut off or start flow of a liquid
2. Prevent hazardous dripping |
