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 times, kaolin combined with spreaders and stickers applied as a spray at concentrations of 1–6% in water has been found to be an effective method for controlling pests in agriculture and protecting plants from environmental stress. Studies on these kaolin-based sprays conducted since 1999 have revealed that they deposit a "particle film" which offers numerous benefits to both plants and insect pest management.
