Uses and applications

What the substance is used for, by industry and function

For Carbophenothion (USEPA/OPP PC Code 058102) there are 0 labels match.

The active ingredient is no longer contained in any registered pesticide products ... "cancelled.".

Carbophenothion is a non-systemic acaricide and insecticide with a long residual action. It is used in combination with petroleum oil, as a spray to control overwintering aphids, mites and scale insects on dormant deciduous fruit trees, and as an acaricide on citrus trees and cotton, in combination with parathion-methyl as a spray to control mites on grapevines, also with sulfur against mildew oidium species, in combination with mevinphos to control mites on top fruit, as a seed treatment against Debia coarctata on wheat. (former uses).

Effectiveness of different insecticides against first and second instar nymphs and gravid females of Drosicha mangiferae was studied under laboratory as well as field conditions.

Carbophenothion at 0.05% gave 100% kill of first-instar nymphs of the pest. Out of 24 insecticides screened against gravid females under laboratory conditions, carbophenothion at 0.025%, was found very effective. Under field conditions, carbophenothion at 0.05% was found to be most effective against gravid females of Drosicha mangiferae.

Use classes: Insecticides.
