Applying herbicides directly to cotton is harmful to the cotton because it is

The reason why applying herbicides directly to cotton is harmful relates primarily to its classification as a broadleaf plant. Broadleaf plants, including cotton, can be particularly sensitive to certain types of herbicides, especially those that are designed to target broadleaf weeds. These herbicides often affect the growth and development of broadleaf crops as well, leading to potential damage or reduced yields.

Herbicides that are effective against broadleaf weeds may inhibit essential physiological processes, such as photosynthesis or nutrient absorption, in cotton plants. This susceptibility means that not only do the herbicides harm the weeds, but they can also unintentionally cause significant harm to the cotton, leading to decreased plant health and productivity.

In contrast, the other options do not accurately reflect the main issue with herbicide application on cotton. While cotton may grow at a slower rate than some weeds, this is not the primary reason for herbicide damage. Similarly, being shorter than weeds does not contribute to susceptibility; it's more about the specific plant structure and function that determine how cotton responds to herbicide exposure. Lastly, the idea that cotton is “attracted” to herbicides is misleading, as it implies a voluntary interaction, whereas the reality is that herbicides can be toxic regardless of attraction,
