Oxykill contains oxyfluorfen as active ingredient which belongs to diphenyl ether.
As pre-emergence, Oxykill forms a chemical barrier on the soil surface and affects weed plants through direct contact at emergence.
Actively growing plants are very susceptible to Oxykill as post-emergence action.
CROPS - Onion, Tea, Potato, Groundnut, Direct Seeded Rice, Mint.
MODE OF ACTION -
Oxykill inhibits specific enzyme, Protoporphyinogen oxidase, which leads to accumulation of phototoxic heme and chlorophyll precursors, which in presence of light, produce activated oxygen species.
These oxygen species disrupts membrane. Sunlight is essential for performance of Oxyfluorfen.
