Prevention
•
Use certified clean seed for growing crops; seeds considered as the main means of spread
•
Clean tools and farm machinery to prevent spread of weed seeds
•
Control established populations near waterways to prevent spread during flooding and storm events
•
Repeated ploughing/cultivation of the field to destroy weed seedlings when the soil is moist before planting or during off-season in order to reduce the population of weeds germinating after planting
Monitoring
•
Annual and erect grasses with an open leaf-sheath, upper leaves have a swollen leaf-sheath which envelopes the inflorescence before flowering
•
Inspect the crop fields a fortnight after sowing for the presence of the weeds, consider control using mannual or chemical control when found
Direct Control
•
Hand-weeding once (3-4 weeks after sowing) for moderate infestation, however if severe infestation additional hand weeding before heading of the crops
Restrictions
•
Use of chemical herbicides may lead to the development of herbicide resistance.
•
When using a pesticide, always wear protective clothing and follow the instructions on the product label, such as dosage, timing of application, and pre-harvest interval.
Direct Control
Post-emergence application 2-3 weeks after planting of Fenoxaprop-p-ethyl (75%) at 1 L/ha, Clodinafop-propargyl (8%) at 1 L/ ha, Pyroxsulam (45%) at 500 mL/ha use to control the weeds
WHO classification: Clodinafop-propargyl: III (slightly hazardous): Pyroxsulam: III (slightly hazardous); Fenoxaprop-p-ethyl: not classified by WHO; based on rat LD50 data considered unlikely to be an acutely hazardous substance in normal use and can be classed as "slightly hazardous to human health"
