Many thanks my dears Jasim and Mohamad for your helpful answers .

My comments about EC & G are as under-

Both the formulations are good for specific purpose, we need to use. please see the following note-

Emulsifiable Concentrates ( EC) An emulsifiable concentrate formulation usually contains an oil-soluble liquid active ingredient, one or more petroleum-based solvents, and a mixing agent. The mixing agent allows the formulation to be mixed with water to form an emulsion.

Advantages:

• Relatively easy to handle, transport, and store.

• Easy to pour and measure.

• Leave little visible residue on treated surfaces.

Disadvantages:

• High concentration of active ingredient(s) makes it easy to overdose or underdose through mixing or calibration errors.

• Easily absorbed through skin of humans or animals.

• Many have a strong odor. .

Granules (G) Granular formulations are having larger granular particles and heavier. & are not water-soluble. . The coarse particles that serve as carriers for granular formulations are adsorptive substances like clay or absorptive plant material such as ground corncobs or walnut shells. The active ingredient either coats the outside of the granules or is absorbed into them. The amount of active ingredient is relatively low, usually ranging from 1% to 15%. Granular pesticides are mostly used to apply chemicals to the soil, where they control weeds, nematodes, and insects or are absorbed by plant roots.

Advantages:

• Ready-to-use; no mixing.

• Drift hazard is low, and particles settle quickly.

• Weight carries the formulation through foliage to soil or water target.

• Applied with simple application equipment, such as seeders or fertilizer spreaders.

Disadvantages:

• Application equipment needs frequent calibration

Granules do not stick to foliage or other uneven surfaces. For this reason, contact products are rarely formulated this way. .

• May need moisture to release the active ingredient; may not be effective in drought conditions.
