The photosynthetic ability of the leaf is reduced with even a small amount of larva damage, and the feeding injury becomes susceptible to opportunistic fungal infection. [3] The buoyancy of the plant is reduced.

Calcium silicates are produced by treating calcium oxide and silica in various ratios. Their formation is relevant to Portland cement. [5]Calcium silicate is a byproduct of the Pidgeon process, a major route to magnesium metal.
A powder is a dry solid composed of many very fine particles that may flow freely when shaken or tilted. Powders are a special sub-class of granular materials , although the terms powder and granular are sometimes used to distinguish separate classes of material.
Dry chemical powder is used on all classes of fires. Dry chemical powder puts out the fire by coating the burning material with a thin layer of dust, thereby separating the fuel from the oxygen in the air. The powder also works to interrupt the chemical reaction of fire, so these extinguishers are extremely effective at putting out the fire.
