Q

Define Adjuvant

A

An adjuvant is a substance added to a pesticide mixture to enhance the pesticide’s qualities.
Adjuvants are substances that are added at the time of application to make the product safer to use, more effective, more convenient to handle, or easier to apply. Adjuvants are registered for specific uses with a specific pesticide. Adjuvants work by:
• Making the spray stick to the surface of the target better
• Improving spray droplet uniformity to give more complete coverage
• Altering the pH of the spray water
• Increasing/decreasing evaporation to improve the drying of the spray mixture.

44
Q

Integrated Pest
Management (IPM):

A

IPM is a systematic decision-making process that aims to prevent pests from becoming problems, and to determine what actions to take if pest problems occur.

45
Q

Injury Threshold

A

The injury threshold is the point when a pest population reaches numbers
such that it causes unacceptable injury or damage, sufficient to justify treatment.
A few individuals of a pest population can usually be tolerated. Treatments should only be considered if numbers increase to, or are likely to increase to, the injury threshold.

Pest treatments have financial costs, and may have other impacts, such as on wildlife or fish habitat or beneficial species. These impacts must be weighed against the benefits of treatment, to determine whether or not treatment is justified.

46
Q

Action Threshold

A

The action threshold (sometimes called treatment threshold) is the point at which a treatment should be started in order to prevent the pest population from reaching the injury threshold. The action threshold depends on the type of treatment as well as on the life cycle and reproductive rate of the pest.

47
Q

The action threshold depends on one or more of the following factors:

A

• Type of pest
• Numbers or extent of pest
• Value/importance of the crop/area being protected
• Stage of the pest in its life cycle or reproductive cycle
Weather conditions
• Type and cost of treatment to be used.

48
Q

Once a decision has been made to treat and manage a pest problem, there are a number of different options to consider in selecting the best form of control. Most treatments fall into one of the following groups:

A

Cultural
Mechanical/Physical
Biological
Behavioural
Chemical (pesticide).

50
Q

Legal Status of Label

A

Legal Status of Label
Pesticide labels are legal documents defined under the Pest Control Products Act. Label information serves as both a practical and a legal guide for proper handling and use of pesticides.
A pesticide label provides basic information on use, limitations, disposal, first aid, contents, precautions, formulation and toxicology. It is required by law that applicators follow the label information in order to make effective, safe and environmentally sound pesticide applications.

The information on a pesticide label helps applicators make sound decisions on pesticide storage, handling, application and disposal. Each pesticide has its own label; the format of the label, however, is standard. Those who buy and use pesticides must know how to interpret the label.

51
Q

Two Components of a Label
A pesticide label has two parts:

A

Two Components of a Label
A pesticide label has two parts:
1. The front or principal information
2. The back or secondary information.

52
Q

Principal Information

A

The principal information is located on the front of a pesticide container. This panel contains information that enables an applicator to identify a pesticide in a number of ways. The principal information also warns of hazards and their nature. Applicators must understand the principal information to ensure that they are using the right product and handling it safely. Principal information consists of ten things.

53
Q

Principal Information Items (Front):

A

Principal Information Items (Front):
1. Trade name or product name
2. Formulation
3. Class designation
4. Purpose or Use
5. Guarantee statement
6. Registration number (PCP Act number)
7. Precautionary shapes, symbols and
words
8. Directions to “Read the label”
9. Name and address of the registrant
10. Net contents.

54
Q

Secondary information gives instructions on how to use the pesticide and what to do in order to protect the health and safety of both the applicator and public. This information is typically found on the back or side of pesticide containers. Sometimes some of the information is in attached booklets or adjacent to the primary information.

A
55
Q

Safety Data Sheet (SDS)

A

Labels on Commercial and Restricted class products may make reference to a document called a Safety Data Sheet (SDS). The Safety Data Sheet provides additional information about a pesticide product. This information can enhance the label information. Under the Pest Control Products Act, a pesticide manufacturer must produce an SDS for all Commercial and Restricted class products.

56
Q

LD50

A

LDs0 stands for Lethal Dose for 50% of the Test Population. The LDs0, or Lethal Dose 50%, is the amount of a substance which in one treatment kills half (50%) of the animals in a test. Test animals are given the pesticide through the skin, (dermal) or through the mouth (oral). The LD50 value is measured in mg of pesticide per kg of body weight of the test animal. The smaller the LDso number, the more toxic the pesticide.
These LD50 values allow us to compare toxicity of different pesticides. They are, however, not an accurate way of determining the amount of pesticide that is likely to kill a person. They only tell us how much pesticide will kill half of the test animals. We assume that people will be affected in a similar way to the test animals, but we cannot be sure. Also, the number does not tell us at what levels the first animals died; it could be at considerably smaller dose than the amount needed to kill half the test animals

57
Q

LC50

A

Toxicity can also be measured with an LC50 test result. The LC50 (Lethal Concentration 50%) is the concentration (expressed in parts per million) of a pesticide in the air or water sufficient to kill half of the test animals exposed to the pesticide. NOTE: The smaller the LC50 number, the more toxic the pesticide. As with LDso, LCso gives us a way to compare the toxicity of different pesticides but does not tell us what levels can harm people.

58
Q

Symptoms of Chronic Toxicity

A

• skin irritation
-Loss of weight
• Tumours
• Organ damage
Nerve damage
• Birth defects.

Q

PCPA

A

Pest Control Products Act
The Pest Control Products Act (PCP) is the most important piece of federal legislation regulating pesticides in Canada.

61
Q

Purpose of the PCP Act

A

The Pest Management Regulatory Agency (PMRA) of Health Canada administers the Pest Control
Products Act.
The main purpose of the PCP Act is to:
• Prevent unacceptable risks to people and the environment from the use of pest control products.
-Ensure that only pest control products of value (that are effective and beneficial) are approved for use in Canada.
-Encourage the development of sustainable pest management strategies by helping to provide access to products that pose lower risks.
-Support sustainable development designed to meet the needs of both present and future Canadians.
-Encourage public awareness and public participation in the pesticide registration process.

62
Q

Pesticide Registration

A

Before a pesticide can be imported, sold or used in Canada, it must first be registered under the PC and have a PCP number.
In order to obtain approval to register a pesticide with the Pest Manager Regulatory Agency of Health Canada, the Registrant must provide scientific data and information
• Product effectiveness in Canadian conditions
• Toxicity to humans, animals and plants
- Food and feed residues
Product fate in the environment
Chemistry of the pesticide.

63
Q

Pesticide Applicator Responsibilities Under the PCP Act

A

Although much of the PCP Act relates to the production, testing and marketing of a pesticide, pesticide applicators have specific responsibilities under the Act. Those responsibilities include the following:
• To possess and use only registered pesticides unless special authorization has been obtained to use an unregistered pesticide.
• Following the instructions contained on the label. It is the applicator’s responsibility to ensure that the pesticide is used, stored and disposed of safely.
-Following label directions when disposing of unused pesticide.
-Not repackaging pesticides for distribution.
