What is the mesh size recommended for soluble materials during agitation?

The correct choice, which recommends a mesh size of 100 mesh for soluble materials during agitation, is based on the need for effective mixing and dissolution while avoiding clogging of the spray equipment. A 100 mesh screen, with openings of about 0.15 millimeters, is fine enough to catch larger particles that could disrupt the flow and application of the herbicide, while still allowing smaller, soluble particles to pass through and dissolve efficiently.

Using a finer screen aids in maintaining a smooth flow during agitation, which is essential to ensure that the herbicide is well mixed and subsequently delivered effectively to the target area. This size balances the need for filtration against the desire to ensure that as many soluble particles as possible are included in the solution, promoting uniformity in the application process.

In contrast, coarser mesh sizes, such as 50 or 75 mesh, may allow larger particles to pass through, which could lead to uneven mixing and potential clogging in nozzles or other equipment during application. Conversely, a mesh size like 150 mesh is excessively fine for many situations and could restrict flow too much, leading to operational difficulties and inefficient agitation. Therefore, 100 mesh is recognized as an optimal choice for achieving the goals of proper agitation and
