It damages leaf tissues, which significantly reduces the rate of photosynthesis

It stimulates the production of more flowers to increase reproductive success

It encourages roots to grow longer to reach more alkaline soil layers

It increases the stability of the stem to prevent wind damage

speed up growth

disrupt hormones

increase respiration

block digestion

It causes the overproduction of methane by soil bacteria

It prevents plants from absorbing shortwave radiation

It increases the pH of the soil, making it too alkaline for roots

It slows down the essential processes of decomposition and nutrient cycling

Pesticides often harm non-target organisms like soil microbes and pollinators, disrupting nutrient cycles and reproduction

Pesticides increase the rate of photosynthesis, causing plants to exhaust their nutrients
