Q. What are pesticides?


A. The Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), defines “pesticide” as (1) any substance or mixture of substances intended for preventing, destroying, repelling, or mitigating any pest, (2) any substance or mixture of substances intended for use as a plant regulator, defoliant, or desiccant, and (3) any nitrogen stabilizer. The term “pest” includes, for example, weeds, insects and rodents.


So, pesticide is an umbrella term that includes herbicides, insecticides, fungicides, and other “-cides.”


Etymology: -cide originates from the Latin word caedere to kill 

Q. What is the difference between pre-emergent and post-emergent herbicides?


A. Pre-emergent herbicides are pesticides that kill plants before they emerge from the soil, while they are still underground. Post-emergent herbicides are pesticides that kill plants that have already emerged from soil, that are visible. Unlike pre-emergents, post-emergents can be used to spot-treat; treating entire areas is not necessary.

Pre-emergents are less toxic than post-emergents.


FALSE

One category is not safer than the other. They simply have different mechanisms of action.
