ILLINOIS PESTICIDE APPLICATOR EXAM RIGHTS-OFWAY STUDY QUESTIONS WITH ANSWERS ( )

1. For the formulation application rate, the concentration rate is based on what? - Answer>>>
Total volume of spray solution rather than area (gallons of formulation per 100 gallons spray
solution)
2. What are the typical injury symptoms of growth hormones? - Answer>>> Leaf rolling
(strapped/cupped), twisting of stems/petioles, root meristem damage; restricted/malformed
lateral roots
3. What are the three steps to estimating pesticide allowance in regards to seasonal restriction
limits? - Answer>>> Determine how many pounds of active ingredient have been
applied, calculate how many pounds of active ingredients are remaining based on the limit,
convert pounds of active ingredient remaining to a product rate to find out how much product
can still be applied without exceeding the limit

6. What five steps can be taken to prevent herbicide resistence? - Answer>>> Scout regularly to
identify resistant weeds, rotate herbicides with different sites of action, apply herbicides in tankmixed/prepackaged/sequential mixtures with multiple sites of action, use mechanical and other
non-chemical control practices, and clean equipment before moving from areas infested with
resistant weeds to areas that are not infested
7. To make a fair comparison between two products or formulations, true equivalents are based
on , not -
Answer>>> Acid equivalency per gallon/lb, lbs active ingredient per gallon/lb
8. What two things does droplet size impact? - Answer>>> Coverage and drift potential
9. Spray droplets smaller than______ microns are at high risk of drifting - Answer>>> 150
10. What are the three ways that droplet sizes can be expressed? - Answer>>> Volume Median
Diameter, percentage of spray volume in droplets smaller than 150 micros, and droplet spectrum
