Why do farmers use pesticides?
Janna Splitter explained that protecting the soil is part of the reason why they use pesticides on their farm.
What happens when pesticide fails?
When the pesticide fails, you’re back to where you started in that the weed and the crop cannot be separated through the use of the herbicide (the herbicide has become ineffective to control that weed). However, before the weed became resistant, the producer had good choices on how to control weeds.”.
How do weeds develop resistance to herbicides?
Graybill: “As weeds grow and continually adapt to their environment, they will develop resistance to herbicide. It’s a natural process. This is to be expected and there are ways which farmers are working to minimize this. One practice is to no longer use just a single product, but partner two products together. Glyphosate (Roundup) is one herbicide for which some weeds have become resistant. This was due to it being over used. It was also often used as the only product. Today, when farmers are spraying herbicides they will use multiple products which slows or even prevents the development of resistant weeds.”

Numerous scientific studies show that eating fruit and vegetables regularly reduces the risk of many cancers , high blood pressure, heart disease, diabetes, stroke, and other chronic diseases.
What Is the Environmental Impact Of Pesticides?
Because pesticides are sprayed over large areas of land, they have a widespread impact on the environment. Research has shown, for example, that over 95% of herbicides and over 98% of insecticides do not reach the targeted pest. This is because pesticides are applied over large tracts of land and carried away by wind and water runoff. As these chemicals travel to other areas, they affect a number of plant and animal species. Additionally, storage, transportation, and production allow some quantities of pesticides to be introduced to the environment.
What is the effect of pesticides on the atmosphere?
Some pesticides also emit volatile organic compounds that react with other chemicals in the atmosphere and create tropospheric ozone, a greenhouse gas that affects how long methane and other hydrocarbons remain in the atmosphere.
How do pesticides get into the air?
Pesticide drift occurs when pesticide is sprayed on crops and carried off by the wind before reaching the plants or when it undergoes volatilization. Herbicide (or pesticide) volatilization is what happens when the chemical reaches its intended destination and later evaporates into the air, being carried downwind. It is more common in warmer climates and seasons when evaporation occurs at a faster rate, preventing the pesticide from being absorbed into the ground.
What happens when pesticides are sprayed on crops?
Pesticide drift occurs when pesticide is sprayed on crops and carried off by the wind before reaching the plants or when it undergoes volatilization. Herbicide (or pesticide) volatilization is what happens when the chemical reaches its intended destination and later evaporates into the air, being carried downwind.
How to prevent pesticides from being carried through the air?
In order to prevent pesticides from being carried through the air, many countries have implemented regulations that require windbreaks or buffer zones around targeted crops. These can take the form of tall pine trees planted around the agricultural land or empty fields surrounding the pesticide-treated area.
How do pesticides affect soil?
Perhaps the most detrimental of these effects is that pesticide causes biodiversity loss in soil. This means the soil has a lower quality overall and is less fertile. Additionally, it removes a large percentage of organic matter .
