Their triggers for germination (rising temperatures coupled with light and anaerobic flooded soils) occur simultaneously with the broadcasting of pre-germinated rice seed into ponded fields. Barnyard and silvertop grasses may also occur in these fields, however they tend to be concentrated on the higher points of a layout where low water levels increase the availability of oxygen. Recommended herbicide programs for water seeded rice entail overlaying alternate modes of action to cover a broad suite of weed species. Many weeds continue to compete with water seeded (aerial sown) rice, maintaining the pressure for ongoing development of herbicide products and programs for use in rice crops. QUICK TAKE l  Two new herbicides with alternate modes of action are demonstrating promise in water seeded (aerial sown) rice for control of annual sedge and broadleaf weeds. l  Both herbicides can be delivered directly to floodwater at early growth stages to maximise application efficiency and rice crop yield potential. l Aerial view of herbicide program trials at Cobram in January 2015.
