摘要:
A herbicidal composition which comprises as an active ingredient a trifluormethanesulfonanilide of the formula: wherein R 1 and R 2 are the same or different and are each independently a hydrogen atom, a halogen atom or a C 1 -C 4 alkyl group, a C 3 -C 6 cycloalkyl group, a C 3 -C 4 alkenyl group, a C 3 -C 5 alkynyl group, a C 1 -C 4 alkoxy group, a C 6 -C 7 aralkyl group, a C 1 -C 4 alkoxy(C 1 -C 4 )alkyl group or a C 2 -C 4 acyl group or taken together with the nitrogen atom to which they are attached form a morpholino group and X is a hydrogen atom a C 2 -C 4 acyl group, provided that R 3 and R 4 are not both hydrogen.
摘要:
The invention belongs to the field of chemical synthesis and discloses a new crystal form of tembotrione, which is a herbicide, a preparation method thereof, and an application thereof as a preparation for plant protection. The present invention obtains a previously unknown, stable, new crystal form D of tembotrione by a suitable method and overcomes the disadvantages of amorphous tembotrione. The crystal form D has a crystal structure completely different from three crystal forms A, B and C reported in WO08110621A, and thus fills a gap in national patent protection of this technology. Compared with tembotrione in other crystal forms, tembotrione in crystal form D has the advantages of a higher melting point, better chemical stability, lower dissolution rate, reduced solubility, and is thus suitable for long-term storage. The crystal structure is highly suitable for storing a tembotrione compound.
摘要:
Disclosed herein are herbicidal compositions comprising a synergistic herbicidally effective amount of (a) clomazone or an agriculturally acceptable salt thereof, and (b) benzobicyclon or an agriculturally acceptable salt thereof. Also disclosed herein are methods of controlling undesirable vegetation in rice, which comprise applying to vegetation or an area adjacent the vegetation or applying to soil or water to prevent the emergence or growth of vegetation (a) clomazone or an agriculturally acceptable salt thereof, and (b) benzobicyclon or an agriculturally acceptable salt thereof, wherein (a) and (b) are each added in an amount sufficient to produce a synergistic herbicidal effect.
摘要:
Compounds of formula (I) wherein the substituents are as defined in claim 1, and the agrochemically acceptable salts and all stereoisomers and tautomeric forms of the compounds of formula I can be used as agrochemical active ingredients and can be prepared in a manner known per se.
