Australian Rice Weed Management


Rice herbicide development in Australia has been supported by RIRDC since 1993 and led to some important local innovations (such as registration of benzofenap and clomazone, and SCWIIRT application technology). We propose to continue and expand this work after a muchreduced program during the drought years on 200220010. Field trials of new and improved weed control programs will be conducted at dedicated sites and in growers commercial rice fields. Specific objectives will include identification and development of alternate mode of action herbicides for waterseeded and drill seeded rice, improved weed control programs for aerobic rice, testing of herbicide drift reduction strategies pertinent to rice and improving agronomist knowledge in relation to rice weeds.

Objective Summary

Seek to identify alternate mode of action herbicides to maintain rice crops free from weed competition, whilst addressing resistance management objectives. Develop data that supports the safe, effective and sustained use of rice herbicides. Test herbicide drift reduction strategies that meet contemporary needs in rice production. Develop improved weed management programs for aerobic/delayed ponded rice crops. Evaluate the tolerance of commerial rice varieties to new and existing herbicide treatments. Improve the knowledge base of Australian rice agronomists by holding annual rice field trial inspections and addressing preseason grower meetings.
