– Banning or deregulation of most toxic products-Regulation and appropriate use of registered products-Using the least toxic, yet effective products-reduce pesticide use-Ablility to measure pesticide risk
Differentiate between Organic and Conventional Pesticide use
-Organic: pesticides derived from natural sources.
Pesticides permitted for use in agricultural systems
Botanical, mineral, microbial
synthetic origin of natural resources or “man-made” chemical classes
not permitted in organic systems.
What is safer? a) Caffeineb) Insecticide
How do we measure Acute Toxicity?
LD50 = the dose of the compound needed to cause the death in 50% of the test population.

The lower the LD50 the more toxicthe compound
Which is safer ? Rotenone (natural insecticide) or DDT (synthetic insecticide)
LD50 Values Rotetone: 132mg/kgDDT: 113 mg/kg
What is the environmental impact quotient?
A method to measure the environmental impact of pesticides
How are environmental impacts assecced?
EIQ= Environmental Impact Quotient(used to rank the relative impact of a given pestcide) Afunction of farm worker, consumer and ecological risks. EIQ is a per unit mass rating of the relative impact of a pesticide-Calculated from MSDS values for toxicity to fish mammals, pollinator, half life, systemicity, etc. EIQ= (farmworker risk + consumer risk + ecological risk)/3
Farm worker risk= C[DT*5) + (DT*P)] What does this equation represent?
-Chronic toxicity x Applicator exposure plus picker exposure.
C= Chronic toxicity C
DT= Dermal toxicity
P= plant surface 1/3 life.
Consumer Risk = [C ((S+P))/2 * SY) + (L) ] What does this equation represent?
Consumer exposure potential + leaching potential)
Consumer exposure = chronic toxicity (C)
x Average for residue potential in soil (S) and plant Surfaces (P) x Systematic potential rating (SY) of the pesticide
