1. Very safe to rice.
2. Taking respective advantages of both Penoxsulam and Fluroxypyr-mepthyl, it is more effective than single formulation, especially more effective to Barnyard Grass, Monochoria Vaginalis and Sagittaria Trifolia.
3. Longer safe treatment period. It can be used from 2 leaf stage to 4 leaf stage.

Barnyard grass, Monochoria Vaginalis., Sagittaria Trifolia, and other broadleaf weeds.

Rice(Direct-sowing field)(Annual weeds).

1.Dosage：Dosage depends on the density and leaf age of weeds, high density and elder weeds need larger dosage. If barnyard grass is over 5 leaf stage or above one tiller stage, then treat with 1.33g/l -1.67g/l Quinclorac 50% WP mixed in bucket.

2. Water layer management：Shallow-layer (at least moist soil) is needed when spraying and make sure 2/3 of weed stems and leaves are out of water. Irrigate within 1-3 days after treatment; keep the height of water layer at 2-3cm for 5-7days.

3. Weather influence：As high temperature and drought may reduce the efficacy, avoid spraying at high temperature especially at noon. High temperature may cause slightly yellowing phenomenon, but it will disappear within 7-10 days and would not affect the yield. Irrigate the field before treatment in dry rice field. Low temperature（<15℃）during spraying may cause slightly yellowing phenomenon of the leaf, but it will disappear within 2 weeks and that would not affect the yield. Normally it will show symptom of phytotoxicity around 5 days, if during low temperature, it may delay to day 10 and dead time will be delayed to week 2 - week 3.

4. For the dry direct-sowing rice field with poor water management, there are a lot of both leptochloachinensis and barnyard, leptochloachinensis comes out later than barnyard grass, treat with Penoxsulam 3%•Fluroxypyr-mepthyl 26% OD + Cyhalofop-butyl together.

6. Small-scale experiments should be conducted before applying with other insecticides and fungicides (mixed in bucket), or consult local department of plant protection.
