What is the main target of Diazinon?

• A. Foliar insects
• B. Soilborne insects
• C. Seedborne diseases
• D. Fungal pathogens

Answer: (B)

Diazinon is primarily targeted towards soilborne insects, making it effective for controlling pests that are found in the soil, such as certain larvae and grubs that feed on plant roots. This insecticide works by disrupting the normal functioning of the insect's nervous system and is often used in agricultural settings where such pests can significantly affect crop yields.

In contrast, foliar insects, seedborne diseases, and fungal pathogens represent different categories of agricultural threats that are not specifically addressed by Diazinon. Foliar insects are typically managed with insecticides designed for leaf applications, while seedborne diseases and fungal pathogens require fungicides or treatments specifically formulated to protect seeds and seedlings from infections. Therefore, the main action of Diazinon against soilborne insects highlights its specific use and efficacy in addressing that particular agricultural challenge.
