What is a common sign of pest infestation in plants?

A common sign of pest infestation in plants is the visible injury on leaves or fruit, such as holes or discoloration. This type of damage often indicates that pests like insects are feeding on the plant's tissues, which can lead to stunted growth, reduced vigor, and even plant death if the infestation is severe. Identifying these physical signs is crucial for early detection and effective management of pest problems, allowing growers to take appropriate action before the issue becomes more serious.

The presence of beneficial insects does not directly indicate a pest infestation. In fact, beneficial insects can help control pest populations, and their visible signs may be more indicative of a balanced ecosystem rather than a problem. Accumulation of soil nutrients is a sign of good soil health and fertility, but it does not reflect the presence of pest issues. Rapid plant growth generally suggests good growing conditions and does not necessarily correlate with the presence of pest problems, as pests often hinder rather than promote healthy plant development.
