Why wouldn't you choose granular if you were going to treat a tree or lettuce crop?

Choosing granular formulations for treating a tree or lettuce crop may not be ideal because granular products often have limited adherence to the leaf surfaces. When treating crops, especially with delicate leaves like lettuce, ensuring that a sufficient amount of the treatment actually contacts the foliage is crucial for effective pest management. If too little of the active ingredient adheres to the leaves, the treatment may not deliver the desired level of pest control, thus undermining the effectiveness of the application.

In the context of crop treatment, it is vital to maximize efficacy while minimizing any negative impact on the plants. Liquid formulations or sprays are often favored in such situations because they can evenly coat the surfaces of the plants, providing better coverage and promoting greater absorption of the pesticide by the target pests.
