Applying too little pesticide leads to inadequate pest control, which is the correct outcome in this situation. Pesticides are specifically formulated to target pests effectively, and their application rates are based on the manufacturer's guidelines and research that ensures optimal pest management. When an insufficient amount is used, it may not reach the levels necessary to affect or eliminate the pest population. As a result, the pests can continue to thrive, potentially leading to increased damage to crops or plants, and further challenges in managing their populations later on.

The other consequences mentioned stem from using pesticides improperly but do not directly relate to the problem of under-application. For instance, increasing residue on plants typically comes from over-application, while higher likelihood of runoff is associated with excessive use or improper application techniques. Legal penalties can arise from misuse or failure to adhere to regulations, but these do not directly correlate with the quantity of pesticide being too low. Hence, inadequate pest control stands out as the primary consequence of applying too little pesticide.
