Abstract

PURPOSE:To provide a novel herbicide containing excelsin, etc., extracted from vegetables as organic components, exhibiting excellent herbicidal effect to various weeds and free from phytotoxicity to important crops such as corn, wheat, rice, soybean, cotton, etc. CONSTITUTION:The objective herbicide contains, as active component, excelsin of formula I separated from Ailanthus excelsa (a plant of Simaroubaceae family) and reported to have carcinostatic activity, or the compound of formula II [ailanthinone (R is group of formula III) or glaucarubinone (R is group of formula IV)], or an extract containing excelsin, ailanthinone or glaucarubinone extracted from a plant. The extraction of the above active component is carried out by conventional process for the extraction of natural component, e.g. by the extraction with an organic solvent such as methanol, acetone, ethyl acetate, etc., followed by concentration, etc. The herbicide is effective against broad- leaved weeds such as white-bird's-eye, green amaranth, etc., gramineous weeds such as barnyard grass, green foxtail, etc., commelinaceous weeds such as dayflower, etc.

DETAILED DESCRIPTION OF THE INVENTION A novel product characterized in that the active ingredient is an extract of a plant containing stamin, exercinone, illancinone, glaucarbinone, or exercinone, illancinone, or glaucarbinone. Conventionally, typical natural organic compounds with herbicidal activity include antibiotics produced by actinomycetes and other microorganisms; ) K-related pheno-/I/-based compounds, acetylene-based compounds, flavone-based compounds, and norditerpenoid lactones are known. As a result of our search for plant components that have herbicidal activity against weeds, the present inventors found that: Quassinoids extracted from plants, such as exercin, ilansinone, and glauca μ.
We have obtained the new knowledge that extracts containing binone or m-reed exercin, ailansinonke young L< or glauca, and binone exhibit significant herbicidal effects against various weeds, and have developed the novelty of the present invention. This led to the completion of a herbicide.
