Description
Conquest Chlorsulfuron 750 WG Herbicide contains 750 g/kg chlorsulfuron. It controls Annual (Wimmera) Ryegrass and certain broadleaf weeds in winter cereals. Growers apply it across wheat, barley, oats, cereal rye and triticale. Conquest Crop Protection registers this product under APVMA number 55189.
This herbicide belongs to the sulfonylurea group. Therefore, it works through a Group 2 (formerly Group B) mode of action. It inhibits the enzyme acetolactate synthase, or ALS. As a result, treated weeds stop growing quickly and then die.
What Does Chlorsulfuron 750 WG Herbicide Control?
Chlorsulfuron 750 WG Herbicide targets Annual (Wimmera) Ryegrass in wheat and triticale. In addition, it controls many broadleaf weeds across all five cereal crops. These weeds include wild radish, capeweed, Paterson’s Curse and wireweed. Growers can apply it two ways. Firstly, they use it pre-sowing, incorporated by sowing. Secondly, they apply it post-crop and weed emergence.
How to Get the Best Results
The product moves through the leaves and green stems of actively growing weeds. Then it travels into the root system. For post-emergence sprays, always add a non-ionic wetting agent. Moreover, apply before Annual Ryegrass reaches the three-leaf stage. Rain or irrigation within four weeks also improves uptake.
Frequently Asked Questions
Q. Which crops can I use Chlorsulfuron 750 WG Herbicide on?
A. You can use it on wheat, barley, oats, cereal rye and triticale. Pre-sowing use suits wheat and triticale only. Post-emergence use suits all five cereals.
Q. What weeds does it control?
A. It controls Annual (Wimmera) Ryegrass and many broadleaf weeds. Common targets include wild radish, capeweed and wireweed. It also suppresses brome grass and saffron thistle.
Q. Do I need a wetting agent?
A. Yes, for post-emergence sprays. Add a non-ionic surfactant at 100 mL per 100 L of spray. However, skip it if your tank mix already contains a surfactant.
Q. Is there a grazing withholding period?
A. No withholding period applies when used as directed. However, avoid grazing treated areas within 24 hours. This timing gives the best weed control.
Q. Can it affect my next crop?
A. Yes, because it has soil residual activity. Therefore, follow the crop rotation table on the label. Higher soil pH also extends the recropping interval.
