Q

What is LD50

A

When a concentrated pesticide active ingredient is dissolved in oil, and both are mixed with emulsifiers, they form emulsifiable concentrates. When emulsifiable concentrates are then mixed in water within a spray tank, they form an emulsion. Emulsions are typically milky in appearance

Termite wings are not clear, but have a milky, translucent appearance. Most wings will be quite clear when held to light. 3. Ants usually have a thin-waisted appearance, because of the modified abdominal segments called pedicel, Termites have a broad-waisted appearance, because they have no pedicel. 4. Ant antennae are elbowed and have the first segment elongated into a scape. Termites have straight antennae, and all segments are bead-like.
