too much movement can transfer a pesticide away from the target pest

How do pesticides harm plants?
In addition to killing non-target plants outright, pesticide exposure
can cause sublethal effects on plants
. Phenoxy herbicides, including 2,4-D, can injure nearby trees and shrubs if they drift or volatilise onto leaves (Dreistadt et al., 1994).
How long do pesticides stay in your body?
Pesticide half-lives can be lumped into three groups in order to estimate persistence. These are low (less than 16 day half-life), moderate (16 to 59 days), and high
(over 60 days)
. Pesticides with shorter half-lives tend to build up less because they are much less likely to persist in the environment.
What happens if you breathe in pesticides?
Respiratory exposure is particularly hazardous because pesticide particles can be rapidly absorbed by the lungs into the bloodstream. pesticides can
cause serious damage to nose, throat, and lung tissue
if inhaled in sufficient amounts. Vapors and very small particles pose the most serious risks.

can contaminate soil, water, turf, and other vegetation
. In addition to killing insects or weeds, pesticides can be toxic to a host of other organisms including birds, fish, beneficial insects, and non-target plants.
How long do pesticides stay in plants?
Under most situations we would encounter in an agricultural setting, a pesticide
half-life can range from a few hours to 4-5 years
. Most pesticides are broken down by microbes in the soil, so environmental conditions that reduce microbial activity (cold, dry conditions) will extend pesticide remaining in the soil.
What are the pros and cons of pesticides?
| Pesticide Pros Pesticide Cons | Pesticides can increase crop yields Pesticides can harm the health of farmers | May improve the growth behavior of plants Pesticides may contaminate crops | Can help to stop the spread of diseases May lead to soil pollution |

What happens if you spray pesticides abnormally on crop plants?
Phytotoxicity, or unintentional pesticide damage to plants, results in abnormal growth,
foliar burn, leaf drop, and discolored, curled, and spotted leaves
(ex. 2, 4-D herbicide injury to grape). If phytotoxicity is severe, the plant may die.
Do pesticides leave your body?

broken down and removed from the body by the liver and kidneys
.
