When making a pesticide application on large trees, you usually need:

The need for low pressure and slow application speed when making a pesticide application on large trees is based on the goal of achieving even coverage and minimizing potential damage to the tree and the surrounding environment.

Using low pressure helps to ensure that the pesticide is not applied too forcefully, which can lead to drift, causing the chemical to move away from the target area and potentially affecting non-target plants and wildlife. Additionally, lower pressure decreases the chances of causing harm to the tree itself, such as bark damage or improperly penetrating the canopy.

A slow application speed allows the applicator to pay attention to coverage and ensures that the pesticide has sufficient time to settle into the foliage, providing more effective treatment. This method helps in achieving better adhesion and absorption of the pesticide, which is crucial for effective pest control on large trees where the canopy can be dense and difficult to penetrate effectively.

Overall, this approach aligns with integrated pest management principles, emphasizing responsible and effective pesticide use while minimizing negative impacts.
