To control jassid infestation in mango (Mangifera indica) crop, Maheshbhai Vasawa of Bharuch district, Gujarat boils "kunaja" leaves in water till it becomes greenish. He then filters this decoction and uses it for spraying on mango trees in proportion of 300 gm to 3 L plain water.
Crop: Mango

Crop Scientific Name: (Mangifera Indica)
Crop Vernacular Name: AAM
Formulation: 300 gm kunaja leaves to 3 L plain water.
Ingredients: Leaves of "kutaja" tree (Wrightiatinctoria)

"Biosynthesis of silver nanoparticles using leaf aqueous extract of Coleus aromaticus, Wrightiatinctoria provides a potential source for the larvicidal and pupicidal activity against Cx. quinquefasciatus. Between the two plants studied, the LC50 and LC90 values indicate that Coleus aromatics synthesized silver nanoparticles were more effective than Wrightiatinctoria.
