Systemic Pesticides and their Effects on Plants and Animals

The claim that systemic pesticides penetrate all organs and tissues of plants and animals is true. Systemic pesticides are designed to be absorbed by plants and animals and then distributed throughout their systems. This allows the pesticides to target pests that may be hidden or difficult to reach. The ability of systemic pesticides to move within the plant or animal is what sets them apart from contact pesticides, which remain on the surface of the plant or animal.

Systemic pesticides can indeed cause allergies and sensitivities in both plants and animals. When these pesticides are absorbed and distributed throughout the tissues, they can potentially trigger allergic reactions or sensitivities in organisms that come into contact with them. However, it is important to note that the severity of these effects can vary depending on the specific pesticide and the organism involved.

The claim that systemic pesticides accumulate the most in lower trophic levels is true. Trophic levels refer to the different levels in a food chain, with lower levels consisting of primary producers (plants) and higher levels consisting of consumers (animals). Since systemic pesticides are absorbed by plants and accumulate in their tissues, it is expected that the highest concentrations of these pesticides will be found in the lower trophic levels. As organisms consume plants or other organisms that have been exposed to systemic pesticides, the concentration of these pesticides may decrease at higher trophic levels.

Regarding the claim that birds are the least affected by pesticides, it is important to note that the impact of pesticides can vary depending on the specific pesticide and the species of bird. While it is true that some bird species may have developed certain adaptations or behaviors that reduce their exposure to pesticides, it does not mean that birds are completely immune to the effects of pesticides. Pesticides can still have negative effects on bird populations, including reproductive issues, reduced fertility, and direct toxicity.

The claim that sterile pesticides make the soil infertile is false. Sterile pesticides, also known as soil sterilants, are designed to kill or inhibit the growth of microorganisms in the soil. They are often used to control weeds or prevent the growth of unwanted plants in specific areas. While sterile pesticides can temporarily reduce the microbial activity in the soil, they do not make the soil permanently infertile. Once the effects of the pesticide wear off or are diluted, the soil can regain its fertility through natural processes.

Overall, systemic pesticides can indeed penetrate the organs and tissues of plants and animals, and they can cause allergies and sensitivities. These pesticides tend to accumulate more in lower trophic levels, but it is important to consider the specific pesticide and the organism involved. While birds may have some adaptations that reduce their exposure to pesticides, they can still be affected by their negative effects. Lastly, sterile pesticides do not make the soil permanently infertile, but they can temporarily reduce microbial activity.
