Pesticide resistance describes the decreased susceptibility of a pest population to a pesticide that was previously effective at controlling the pest pest species evolve pesticide resistance via natural selection: the most resistant specimens survive and pass on their acquired heritable changes traits to their offspring. Prolonged pesticide use also brings in a lower agricultural output and reduces soil fertility by deteriorating several necessary compounds previously mentioned, such as nitrogen genetic diversity is another notion aimed to increase pesticide resistance. A problem currently limiting the usefulness of herbicides is that they must distinguish between the crop and the pest — plants that often have biochemical similarities thus researches have looked for more and more specific herbicides to kill the pest but spare the crop.
