  • Biological Control Of Weeds Using The Metabolites Of Alternaria Alternata
    Publication number: 20080280761
    Abstract: The present invention is about a method of controlling weeds using the metabolites tenuazonic acid, iso-tenuazonic acid and their salts isolated from the cultures of Alternaria alternata (Fr.) Keissler. The spray of one of these compounds at the rate of 5 to 800 ?g/g can cause the main broad leaf, grassy and sedge weeds to hurt, wilt, even dry to death which exhibits herbicidal activity with broad spectrum, quick killing and efficient effect. The addition of adjuvants improves their herbicidal activity.

  • NOVEL HERBICIDES AND METHODS FOR PREPARATION THEREOF
    Publication number: 20080176748
    Abstract: A series of herbicidal molecules derived from 3-acetyl-4-hydroxy-5-sec-butylpyrroline-2-ketone, a natural substance, and their potential use in agriculture for weed control. Through the modification of the 5-sec-butyl hydrocarbon chain and 3-acetyl group and the analysis of their biological functioning, newly designed molecules are superior to the original compound in herbicidal activity. These molecules inhibit the photosynthesis of the plants. The treated plants show significant damage in 24 hours and die within 3-5 days after the chemical treatment. In addition, the new molecule has relatively simple structure, they are easy to make and they have better physical properties. They are broad-spectrum, high potency herbicides.
