Application of solid TiO 2 -NPs
against rice weevil Sitophilus
oryzae
Application of solid TiO 2 -NPs (anatase-hydrophilic,
anatase-hydrophobic, rutile) separately, at 0.5–2.0 g Kg
−1
showed up to 90% mortality against rice weevil Sitophilus oryzae
after 7 day of treatment.

TiO 2 -NPs
Use of TiO 2 -NPs treated leaves
for insecticidal activity against
Spodoptera littoralis (Egyptian
cotton leaf worm)
TiO 2 -NPs was more effective against the 2nd instar larvae
(LC 50 62.5 ppm); than the 4
th instar (LC 50 -125 ppm);
malformations in larvae, pupae and adult stages.

Ag-doped hollow and
solid TiO 2 -NPs
Against phytopathogens
Fusarium solani and Venturia
inaequalis
Hollow Ag doped TiO 2 -NPs were found to be more efficient than
solid. Visible light exposure further increased its antifungal
activities; inhibited naphthoquinone pigment production: a
pigment responsible for pathogenicity of F. solani.

TiO 2- NPs
Against—Pectobacterium
betavasculorum, Xanthomonas
campestris pv. beticola
(Pammel), and Pseudomonas
syringae pv. Aptata
Application TiO 2 -NPs (0.25 and 0.50 mLL
−1 ) increased plant
growth, chlorophyll, carotenoid, antioxidative enzymes, proline
and H 2 O 2 contents, but decreased MDA content in presence or
absence of bacteria; also reduced the disease indices of beetroot
(Beta vulgaris L) pathogens-Soft rot and bacterial pocket, leaf
spot caused by pathogens.
