Endophytic bacteria, compositions comprising the same, and methods of use thereof are disclosed which suppress growth of aggressive, invasive weed species which grow in the same habitat of target plants of interest.

The invention provides herbicidal compositions and methods for weed control with the herbicidal compositions comprising auxin or auxin-like herbicide and ethoxylated lecithin. The undesired vegetation may be controlled using the herbicidal compositions and methods within and without damage to agricultural crops, turf grasses, or ornamental plants. The herbicidal compositions and methods of use disclosed provide for the improvement in post-emergence undesired vegetation control.

An isoxazolin-5-one derivative represented by the following (1): ##STR00001##
wherein R.sup.1 represents a C1-C6 haloalkyl group, and R.sup.2 to R.sup.4 and X each represents a certain substituent or the like; and n represents an integer of 1 to 4, wherein X's may be different from each other when n represents an integer of 2 to 4, and an herbicide containing the isoxazolin-5-one derivative as an active ingredient are provided.

Disclosed are compounds having a monoterpenoid and/or phenylpropanoid moiety and methods of their making and use as pesticidal compounds, such as seed treatments.

The present invention uses compound 3-OH-β-apo-13-carotenone (zaxinone) as a negative regulator of the plant hormone strigolactones (SLs). The compound 3-OH-β-apo-13-carotenone is a positive growth regulator which triggers the formation of crown roots and promotes growth in size and number of roots and shoots. Disclosed herein is a method of using 3-OH-β-apo-13-carotenone as a growth-promoting compound for cereal, grain and vegetable crops. The 3-OH-β-apo-13-carotenone compounds is also a negative regulator of strigolactone biosynthesis and release. Disclosed herein is a method of combating root parasitic weeds affecting cereal, grain and vegetable crops. Application of 3-OH-β-apo-13-carotenone to plant growth media down-regulates strigolactone production in cereal, grain and vegetable crops preventing root parasitic weed infestation of the crops by inhibiting germination of parasitic weed seeds.

Disclosed are methods for selectively controlling or modifying the growth of Poa annua in a turf grass using a composition comprising an herbicidally-effective amount tebuconazole, or a salt thereof.

The present invention provides methods of reducing injury to rice and achieving weed control by treating the rice with both a safener and a microencapsulated Group 15 herbicide. Herein, the inventors demonstrate that the tolerance of fenclorim-safened rice to the Group 15 herbicide acetochlor is substantially enhanced when this herbicide is applied as a microencapsulated formulation, particularly when it is applied preemergence or delayed preemergence. Rice plants produced by these methods and seeds produced by said rice plants are also provided.

The present invention relates to a method for effectively controlling herbicide resistant weeds such as Spermacoce verticillate. The present invention provides a method of reducing the population Spermacoce verticillate weeds by applying sequentially a herbicide combination to target said weeds.

The present invention relates to Halauxifen based multi component, and particularly two-component herbicides, comprising, combinations, that comprise, as component (a) Halauxifen, and agriculturally acceptable derivatives including salts and esters thereof, and most particularly, Halauxifen-methyl, applied with component (b) co-herbicides which are each chosen to be tailored to be particularly useful in combination with a) for weed control options in specific crops, weeds and application modalities, be they cereals, oilseed rape, sunflower and soy crops. The b) co-herbicides are each chosen from, Propaquizafop; Clethodim; and any and all combinations thereof, for tailored and or selective control of unwanted vegetation. Besides other advantages, the invention has particular utility in inter alia, reducing each herbicidally active ingredient in the multi component, and particularly two-component herbicide to below the herbicidally effective amount applied while providing selective control of undesired vegetation or weeds, particularly Broadleaf weeds.
