Not regularly reapplying protective chemicals can indeed heighten the chances of disease spread. This is primarily because protective chemicals, such as fungicides or insecticides, are designed to create a barrier on plants or protect them from certain pests and diseases. If these chemicals wear off or degrade over time without being reapplied, the plants are left vulnerable to pathogens and pests that can cause diseases.

When protective measures are not in place, the likelihood of diseases establishing themselves increases significantly. For example, if a fungicide is not reapplied as needed, fungal spores can infect plants, leading to widespread disease that can compromise plant health. This can not only affect individual plants but can also lead to an outbreak that can adversely impact neighboring crops or plants in the area.

By ensuring that protective chemicals are reapplied regularly, the risk of these diseases can be managed effectively, helping maintain plant health and yield.
