Which type of pesticide is known to control most of the plants it is applied to?

The correct choice is a nonselective pesticide, which is designed to kill a broad range of plant species. These pesticides do not discriminate between different types of plants, meaning they will affect most of the vegetation they come into contact with. This makes nonselective pesticides highly effective for clearing out unwanted weeds or vegetation, especially in areas where you want to eliminate all plant life before replanting or for maintenance of non-cultivated areas.

In contrast, herbicides that are selective target specific plants while leaving desirable plants unharmed, making them suitable for use in agricultural settings where crops are grown alongside weeds. Insecticides, on the other hand, specifically target insect pests and do not have a direct effect on plants. Therefore, the ability of nonselective pesticides to control almost all plants they are applied to makes them a unique category in pest management.
