| 摘要 |
<p>The invention provides insect control compositions comprising aqueous dispersions of a hydrophobic substance and a hydrophilic substance. The hydrophobic substance is insecticidal or insect-deterring and can be silica dioxide. The hydrophilic component increases the physico-chemical stability of the dispersion and modifies the textural, visual and/or olfactory characteristics of surfaces to which the compositions are applied; it can be a powdered or finely-divided organic or inorganic substance. The compositions can be applied to plant surfaces by spraying.</p> |
