Usage

General Description

(2,4,5-Trichlorophenoxy)acetic acid, also known as 2,4,5-T, is a synthetic herbicide that was commonly used to control broadleaf weeds. However, due to its toxic and harmful effects on humans and the environment, it has been banned in several countries. Exposure to 2,4,5-T has been linked to various health issues, including skin and eye irritation, respiratory problems, and potential carcinogenic effects. This chemical was also one of the components of Agent Orange, a herbicide used during the Vietnam War, which has led to severe health problems in exposed individuals. Despite its ban, 2,4,5-T continues to have long-lasting environmental impacts, as it can persist in the soil and water for an extended period.

Synthesis, Structure, and Properties of the 2-[5-(Aryloxyacetyl)-Amino-1,3,4-Thiadiazol-2-Ylthio] Propionate Derivatives

A series of novel 2-[5-(aryloxyacetyl)-amino-1,3,4-thiadiazol-2-ylthio] propionate derivatives were synthesized in high yield, and their structures were characterized by IR, 1H NMR, 13C NMR, and elemental analysis, coupled with one selected single-crystal X-ray structure determination. The herbicidal activities of target compounds were assessed. The preliminary bioassay results showed that some compounds exhibited moderate to strong herbicidal symptoms in preemergence and postemergence tests. At 150 g/ha, S. tritici. show tolerance, while E. crus-galli L., E. Dahuricus, A. retroflexus, and C. glaucum L. were killed or severely injured. The activity of some compounds was comparable to the commercial herbicide 2,4-D. A suitable electron-withdrawing substituent at the 2-and/or 4-position of the phenyl ring was essential for high herbicidal activity. Moreover, the antifungal activities of the compounds have also been studied. The compounds were found to possess broad-spectrum antifungal activity.

Soluble polymer based matrix for chemically active water insoluble components

This invention relates to a water soluble matrix composition comprising an anionic surfactant, a C6 to C18 alkyl pyrrolidone, urea and a water insoluble copolymer of vinyl pyrrolidone with not more than 50 wt. % of a comonomer selected from the group of an α-olefin, vinyl acetate, an acrylic or methacrylic acid ester and methacrylamide as a free flowing particulate solid which matrix is suitably mixed with a water insoluble, chemically active component, such as an agrochemical, to provide a clear sprayable film forming emulsion, such as a non-leachable film on a plant or other substrate surface. The invention also relates to the method of preparing the matrix and to the incorporation of an agrochemical concentrate and plant spray composition.
