What are the symptoms of soil compaction, pesticide or fertilizer excess, temperature and moisture extremes?

  1. Noninfectious disease

  2. Pest infestation

  3. Fungal infection

  4. Bacterial disease

The correct answer is: Noninfectious disease

Noninfectious disease refers to symptoms that are not caused by a living organism or pathogen. In this question, the symptoms of soil compaction, pesticide or fertilizer excess, temperature and moisture extremes are all abiotic or nonliving causes. Therefore, they are not considered as noninfectious diseases. Option B, C, and D are all types of pest or pathogen infestation which are incorrect as they are referring to infectious causes rather than noninfectious ones.
