1. Which of the following best describes the primary legal principle
governing pesticide use under federal and Texas regulations?
A. Pesticides may be applied according to manufacturer preference if safety
precautions are followed
B. Applicators may modify label instructions if environmental conditions
require adjustment
C. Pesticide labels are advisory unless otherwise stated by state law
D. Pesticides must be used strictly in accordance with label directions, as
the label is the law
Rationale: The Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA)
establishes that the pesticide label is a legal document, meaning all use
must strictly follow label directions and restrictions without deviation.
2. What is the primary purpose of the Worker Protection Standard
(WPS)?
A. To regulate pesticide pricing in agricultural markets
B. To ensure pesticide manufacturers meet environmental standards
,C. To protect workers from pesticide exposure in agricultural settings
D. To certify pesticide applicators for restricted-use products
Rationale: The WPS is designed to reduce pesticide exposure risks for
agricultural workers and pesticide handlers through training, notification,
and protective measures.
3. Which of the following is a Restricted Use Pesticide (RUP)
requirement?
A. It may be purchased by any consumer without restriction
B. It can be applied only by certified applicators or supervised personnel
C. It is exempt from labeling requirements
D. It does not require recordkeeping of applications

A. Soil texture
B. Wind speed and droplet size
C. Pest resistance levels
D. Tank mixing compatibility
Rationale: Drift is primarily affected by environmental conditions such as
wind and application variables like droplet size and spray pressure.
7. What is the primary purpose of Integrated Pest Management (IPM)?
A. Eliminate all pests using chemical control only
B. Use multiple control methods to manage pests economically and
environmentally
C. Replace all pesticide use with biological control
D. Increase pesticide application frequency to prevent resistance
