Which factor primarily contributes to plant loss in greenhouses?

In the context of greenhouse management, overwatering is indeed a significant contributor to plant loss. When plants receive too much water, it can lead to root rot and other fungal diseases, which can ultimately cause the plants to wilt or die. Proper irrigation practices are crucial to maintaining healthy plants within a greenhouse environment.

Pest infestations can also heavily impact plant health by feeding on the plants or transmitting diseases, making it another noteworthy factor in plant loss. However, while pests can cause substantial damage, effective pest management techniques can mitigate their effects.

Exposure to extreme temperatures is a critical environmental factor that can lead to plant stress or lethal conditions. Both heat and cold extremes can severely impact growth and health, potentially leading to death if plants are not acclimatized or if the greenhouse conditions are not properly controlled.

Toxic chemical exposure is an important consideration, but typically greenhouse environments are managed to minimize such risks. When chemicals are used properly, the risks to plants are usually controlled. In contrast, improper watering practices, pest management, and temperature regulation often have more immediate and widespread impacts on plant health, leading to loss.

By addressing the factors of overwatering, pest infestations, and temperature extremes, greenhouse managers can significantly reduce the risk of plant loss, making these
