More recently, kaolin mixed with spreaders and stickers and applied to plants as a spray at 1–6% concentration in water form has been shown to be an effective approach to agricultural pest control and to protect plants from environmental stresses. Kaolin-based sprays have been studied extensively since 1999 and research has established that these sprays deposit a "particle film" that has numerous beneficial effects on plants and in insect pest control.
In recent years, kaolin mixed with spreaders and stickers has been used as a spray at concentrations of 1–6% in water to manage pests in agriculture and protect plants from environmental stress. Research since 1999 indicates that these sprays deposit a "particle film" which provides various benefits for both plants and insect pest control.
