Type of liquid pesticide formulation that contains a liquid a.i. one or more petroleum-based solvents, and a substance that makes them miscible with water. Among its advantages are their versatility and no much need for agitation. However, its disadvantages are the fact that given its high concentration of active ingredient, it is easy to overdose or underdose them and cause phytotoxicity on crops

• A. Emulsifiable concentrate
• B. Wettable powder
• C. Granular
• D. Aqueous dispersion

Answer: (A)

Emulsifiable concentrates are liquid formulations in which a liquid active ingredient is dissolved in one or more petroleum-based solvents along with an emulsifier that lets the mix form a stable emulsion when diluted with water. This setup makes the product highly versatile: it can be stored as a concentrated liquid and then diluted to the needed spray volume, and it generally requires less agitation to maintain a uniform mixture once diluted because the active ingredient is already in solution and the emulsifier helps it blend with water. The notable downside is the risk of phytotoxicity because the concentrate contains a high concentration of active ingredient and solvents; improper dosing or incomplete mixing can injure crops. Other options don’t fit the description: wettable powders are solid materials that must be wetted and dispersed in water; granular formulations are dry particles; aqueous dispersions are suspensions of solids in water.
