PESTICIDE MOVEMENT IN SOIL

DR. MICHAEL PFEIFFER

The relative ease with which pesticides move in soil

has a profound effect on control of target pests in soil

and on protection of the environment. The ability of a

pesticide to move within soil can be quite beneficial in

controlling pests in soil and can potentially be very

damaging if the material reaches groundwater and

becomes a pollutant. Knowledge of the potential

movement of specific pesticides is essential for

successful control of soil borne pest and in protecting

the environment.

Many things have to be factored in when considering

the potential of a specific pesticide to pollute ground

water. Some of the factors which determine whether a

particular pesticide could pollute ground water are:

nearness to the surface of the groundwater, soil type and

pH, microbial populations, amount of irrigation or

rainfall, water solubility of the active ingredient (a.i.),

degree of absorption or adsorption of the a.i. to soil or

organic matter, persistence of the a.i. and the amount of

product applied. None of these single factors by

themselves can be used to reliably predict whether or

not a particular product will become a ground water

pollutant.

The tables below are only general guidelines for the

potential of specific products to pollute ground water

and should not be considered as an endorsement.

Remember, many factors are involved in whether or not

a particular product is likely to pollute groundwater.

The data in these tables in most cases was generated

from the OSU, Extension Pesticide Properties Database.

The OSU database relies heavily on databases devel-

oped by USDA. References are presented.

The relative leaching potential of specific materials are

grouped by type of pesticide: insecticides, herbicides

and fungicides. The common names for pesticides are

presented followed by some or all of the currently used

trade names in parenthesis. Due to space limitations, not

all trade names could be included in these tables.

Apologies are extended to companies whose trade

names are not entered in these tables.
