The difference between traditional pesticides and water-soluble pesticide beads lies in their physical forms and modes of application. Traditional pesticides are often in liquid or powder form and require to be mixed with water before application. On the other hand, water-soluble pesticide beads are already in a concentrated form and dissolve in water easily.

As for which one is better and more suitable for agriculture, it depends on various factors such as the type of crops, pests, and environmental conditions. Both traditional pesticides and water-soluble pesticide beads have their own advantages and disadvantages. Traditional pesticides may be more readily available and have a longer shelf life, while water-soluble pesticide beads may offer more precise dosing and reduce environmental pollution.

Ultimately, the choice between traditional pesticides and water-soluble pesticide beads should be based on careful consideration of the specific circumstances and needs of each farming situation.
