Paddy Queen
Quinclorac 30% + Bispyribac sodium 5% WP
Product Feature
- Paddy Queen is a systemic and selective herbicide.
- It absorbed by the plant and translocated to growing regions, ensuring through control of both the roots and shoots of the weeds.
- Quinclorac is a synthetic auxin (plant hormone mimic) that disrupts weed growth by affecting cell division and elongation, causing the weed to grow irregularly and eventually die.
- It is particularly effective against crabgrass and other grassy weeds like barnyard grass, as well as some broadleaf weeds such as clover.
- Bispyribac sodium is a ALS inhibitor (acetolactate synthase inhibitor). It stops protein synthesis and cell division, effectively halting plant growth.
- It is especially effective against grassy weeds like barnyard grass, as well as certain broadleaf weeds in rice field.
- Paddy Queen is highly effective for post-emergence control of both broadleaf weeds and grassy weeds in rice field.
- It provides a synergistic effect, where quinclorac controls grassy and broadleaf weeds, and bispyribac sodium helps manage difficult-to-kill grass species and certain sedges.
