Effective weed control for Trifolium tumens and Dorycnium hirsutum seed crops
Summary Two new legume species under development, Dorycnium hirsutum and Trifolium tumens, offer new opportunities to develop persistent and productive perennial pastures in dry and challenging areas of temperate Australia. The success of the introduction of these species into Australian farming systems is heavily dependent on commercially viable seed production, of which developing a suitable weed control programme is critical. The principal project objective is therefore to advance the development of commercial seed production for Trifolium tumens and Dorycnium hirsutum, through establishment of an effective herbicide program for management of weeds in seed crops of these species.
Two cultivars of T. tumens, and one cultivar of D. hirsutum will be assessed in a range of field and glasshouse experiments. A range of pre and postemergent herbicides will be used at multiple rates, both at establishment, and on mature legume stands. The effect of the herbicides on the legumes will be monitored, using such measurements as vegetative yield at various growth stages, floral numbers, floral structure, and seed yield.

Objective summary The principal project objective is to advance the development of commercial seed production for two new alternative perennial legume species, Trifolium tumens and Dorycnium hirsutum, through establishment of an effective herbicide program for management of weeds in seed crops of these species.
Component objectives include:
1. Production of guidelines in the use of pre and postemergent herbicides for T. tumens and D. hirsutum commercial seed crops.
2. Increased ability of seed producers to economically produce seed of T. tumens and D. hirsutum, through improved pre and postestablishment weed control.
3. Facilitating commercial production of two perennial legumes that are potentially both economically and environmentally important.
