There is a need for a selective, low-risk herbicide that can be used to control weeds in cereal cultures and turf. The present invention discloses that a bacterial secondary metabolite, thaxtomin and optionally another herbicide is an effective herbicide on broadleaved, sedge and grass weeds. Thaxtomin A and structurally similar compounds can be used as natural herbicides to control the germination and growth of weeds in cereal, turf grass, Timothy grass and pasture grass cultures with no phytotoxicity to these crops. As a natural, non-toxic compound, thaxtomin can be used as a safe alternative for weed control in both conventional and organic farming and gardening systems.
A method for modulating germination and growth of monocotyledonous, dicotyledonous and sedge weeds in a non-rice cereal crop growth system and/or a turf grass growth system and/or Timothy grass growth system and/or pasture grass growth system, comprising applying to said weeds or soil in said growth system at least one herbicidal agent, wherein said herbicidal agent is thaxtomin, in an amount of effective to modulate growth of said weeds but not modulate growth of non-rice cereal crop in said non-rice cereal crop growth system and/or turf, pasture and/or Timothy grass in said turf, pasture and/or Timothy grass growth system.
The method according to claim 3, wherein said turf grass is selected from the group consisting of Festuca sp., Poa sp., Bromus sp., Lolium sp., Agrostis sp., Zoysia sp., Cynodon sp.
A method for modulating growth of monocotyledonous, dicotyledonous and sedge weeds and aquatic weeds selected from the group consisting of Ammania sp., Alisma plantago-aquatica, Cyperus sp., Leptochloa sp. comprising applying to said weeds or soil an amount of at least two herbicidal agents effective to modulate growth of said weeds, wherein a first herbicidal agent is thaxtomin.
An herbicidal composition comprising at least two herbicides wherein a first herbicide is thaxtomin and a second herbicide is a bioherbicide or chemical herbicide.
