Q

Why are chronic health effects more difficult to diagnose than acute health effects?

A

complexity of human health, genetics, diet, and exposure to substances in the environment makes it difficult to diagnose the exact cause of a chronic health effect.

Q

Cholinesterase

A

enzymes found in humans, insects, and other species that are necessary for normal function of the nervous system

Organophosphates and Carbamates can block and inhibit these enzymes

Q

When should you have your cholinesterase level in your blood monitored?

A

establish a baseline for normal activity and be alerted to any drop in enzyme levels before they reach values low enough to make you sick. Workers can be removed from exposure before symptoms occur. Natural recovery normally occurs when exposure stops

Q

How do you compare pesticide formulations that are more and less toxic to bees?

A

dusts are more hazardous that sprays.
wettable powders usually provide a significantly longer toxic hazard that EC because dry particles cling to the body hair of bees

Microencapsulations are the most hazardous type

Q

How does temperature affect the impact of pesticides on bees?

A

honey bees can become active at temperatures as low as 55

temperature has a significant modifying effect of the bee poisoning hazard of a pesticide.

Bees act differently depending on the temperature (foraging at night, drinking puddles)

Q

What is the difference between bees are actively visiting and bees are visiting ?

A

actively visiting - bees that you see on the plants
are visiting - bees that are on the plants as well as bees that may visit the plants after treatment (indicates an extended residual toxicity)

Q

Why do neonicotinoid insecticides pose a risk to bees?

A

they degrade relatively quickly in the environment and are persistent. even as they degrade they continue to remain toxic to bees

Q

What is the purpose of monitoring?

A

regular and through inspecting of a site. important in determining the need for control actions as well as a way to assess whether control actions actually worked

21
Q

Assessment

A

the process of determining the potential for pest populations to reach an action threshold

22
Q

How is forecasting used to manage pests

A

an assessment process can help you determine if weather conditions will be favorable for the development of disease and insect pests

23
Q

Cultural Control strategies

A

plowing, crop rotation, removal of infected plant material, sanitation

24
Q

physical/mechanical control strategies

A

structural modification, barriers, light traps, heat treatment, handpicking

25
Q

How can natural enemies manage pests

A

natural enemies can help manage pests either as predators, parasites, or disease

26
Q

biological control: introduction

A

the release of natural enemies of pests into new areas or regions

27
Q

biological control: augmentation

A

the addition of natural enemies directly into a system to reduce pest numbers

28
Q

biological control: conservation

A

methods which preserve and encourage natural enemies that are already present

29
Q

microbial peticide

A

microorganisms such as guns and bacteria formulated as pesticids

30
Q

biochemical pesticide

A

include pheromones, and insect and plant growth regulators, and hormones

31
Q

minimum risk pesticide

A

active ingredients that pose little harm to humans and the environment such as corn oil, mint oil, garlic etc.

32
Q

role of record keeping in implementing IPM

A

involves the systematic storing and retrieval of IPM information extensive records can provide indications of increasing or decreasing pest

33
Q

role of communication and education in IPM

A

having informed individuals available to report pest problems or conditions conducive to these problems

34
Q

What are the four major components of IPM

A
  1. take preventive measures
  2. monitor
  3. assessing the pest situation
  4. determine the best action to take
35
Q

biological pesticides

A

pesticides that are natural occurring and genetically engineered microorganisms, and naturally occurring compounds that are not toxic to the target pest

36
Q

applicator license (core license)

A

required to use general use pesticides on the property of another for hire or as part of your current job duties on the property of your employer

can only apply restricted use pesticides under the supervision of an appropriately certified applicator

37
Q

private certification

A

required to use restricted use pesticides on an agricultural operation

38
Q

commercial certification

A

required to use restricted use pesticides on the proper of another for hire

39
Q

dealer license

A

required to sell products classified as RUP to pesticide applicators

40
Q

what is the definition of under the direct supervision of a certified applicator

A

if it is applied by a competent person acting under the instruction and control of a certified applicator who is available if and when needed, they are responsible for the pesticide applications made by that person

41
Q

What is the role of the US EPA and MDAR in registering pesticides

A

EPA is responsible for registering pesticide used in the US

The pesticide manufacturing co has to register the product in every state they plan to distribute and sell to. MDAR can determine that a particular pesticide product will be reclassified and register as a state RUP

42
Q

What is the purpose of consumer bulletins

A

documents that pesticide applicators must give to their customers before pest management service occur .

43
Q

What is the location and/or type of pesticide applications that require consumer information bulletins?

A

lawn, trees, indoor areas, schools, day care facilities, after school program, buildings

44
Q

Goal of OSHA

A

to assure the healthful working conditions for working people

45
Q

employees responsibility regarding Hazard Communications in the workplace

A

identify hazards and take steps to minimize those hazards for their employees

46
Q

what is the difference between MSDS and SDS

A

they are the same but the SDS has a standard 16 section format

47
Q

how does the info found on pesticide labels differ from MSDS/SDS

A

SDS includes information about chemical ID, hazards, first aid measures, fire fighting measures, handling and storage, exposure control and toxicological info

48
Q

Why should pesticide applicators read and understand the MSDS/SDS

A

required to comply with the MSDS/SDS
ensure that you have access to important information
contains info not always found on the pesticide label
