Question on: JSS1 Agricultural science - Common Pests and Diseases in Crops

The causes and spread of crop diseases involve various factors:

  - Pathogens: Microorganisms such as fungi, bacteria, and viruses are primary causes of diseases in crops.

  - Environmental Conditions: Favourable conditions, including temperature and humidity, can facilitate pathogen growth and disease development.

  - Vectors: Insects and other organisms can transmit pathogens from infected to healthy plants, contributing to disease spread.

  - Soil and Water: Contaminated soil and water sources can harbour pathogens, leading to the spread of diseases.
