Volumizing agents

A method of treating plants comprising:

• applying an amount of a slurry to a plant surface, said slurry containing water and a composition, wherein the slurry when dried forms a volumized high opacity particle film having a thickness of about 3 μm to about 3,000 μm on said plant surface, said composition comprising:
• (a) between about 70% to about 99.9% by weight of mineral particles having a median individual particle size of about 3 μm or less;
• and
• (b) 0.35% by weight or more of at least one volumizing agent, wherein the volumizing agent is present in an amount sufficient to increase the opacity of the high opacity particle film compared to the opacity of a film formed by the same amount of an identical composition except not having the volumizing agent.

A method of treating plants comprising:

• applying an amount of a slurry to a plant surface, said slurry containing water and a composition, wherein the slurry when dried forms a structured particle film having a thickness of about 1 μm to about 750 μm on said plant surface, said composition comprising:
• (a) between about 70% to less than 99.65% by weight of mineral particles having a median individual particle size of about 3 μm or less;
• and
• (b) 0.35% by weight or more of at least one volumizing agent, wherein the volumizing agent is present in an amount sufficient to cause individual particles to form structures resulting in the film to be volumized upon drying, having a substantially greater structured volume compared to the volume of a film formed by the same amount of an identical composition except not having the volumizing agent.
