True or False: It is almost impossible to spray a crop with a herbicide to kill the weeds without injuring the crop.

The statement is false because herbicides are designed to target specific types of plants, primarily weeds, while minimizing damage to crops. This selective action is achieved through the use of different active ingredients that affect the biology of the target species without harming the crop species.

For example, there are many herbicides that are specifically formulated as "selective" herbicides, which means they can control weeds without harming certain crops. This is made possible through the understanding of plant physiology and biochemistry, allowing for targeted applications that protect the desired crops. Additionally, the timing of the application and the method of spraying also play critical roles in achieving effective weed control while reducing the risk of crop injury.

Herbicides can be chosen specifically based on the type of crop and the species of weed present, further enhancing their effectiveness while preserving the health of the crop. Consequently, with proper selection and best practices, it is indeed quite feasible to spray crops with herbicides to control weeds without causing injury to the crops.
