摘要:
The decrease in soybean rust control using fungicide mixtures (DMAs+QoIs) reached very low levels for the harvest of 2012/13 (an average of 37% for the three main mixtures). This decrease is due to a decrease in Pp sensitivity to individual DMIs and QoIs, and mixtures thereof. Anti-resistance strategies have not been introduced in Brazil for preventing/delaying the development of resistance of the fungus that is the casual agent of rust (Phakopsora pachyrhizi) in soybean [plant form the family Fabaceae, Glycine max (L.) Merr.] and of the fungus that is the casual agent of yellow leaf spot (Drechslera tritici-repentis) in wheat [plant of the family Triticea, Triticum aestivum L.], as well as other disease complexes that attack the main crop plants in Brazil, such as corn, beans, cotton, inter alia. By means of said method it is possible to recover the efficiency of several mixtures (DMI+QoI and QoI+SDHI) due to a decrease in fungal sensitivity. The methods described by the present invention seek to increase the effective useful life of fungicides and increase grain yield.
摘要:

摘要:
The present invention provides a temperature stable herbicidal composition comprising 2-amino-4-[hydroxy(methyl) phosphinoyl]butyric acid, its salts, its isomers, mixture of isomers, derivatives or their lower alkyl esters or salts thereof with acids or bases, (C8-C20) alkyldimethylamine N-oxide and an inorganic ammonium salt. Also provided is a process for preparing the composition by mixing said active ingredient in a formulation vessel with water and solvent followed by the addition of calculated amount of (C8-C20) alkyldimethylamine N-oxide and inorganic ammonium salt, and if required further customary adjuvants, solvents or other components such as wetting agent, coloring agent or defoamer followed by homogenizing the resultant mixture to obtain a clear solution. A method of weed control applying the composition of the present invention as well as a multipack herbicidal product comprising the composition are within the purview of the present invention.
摘要:
A capsule suspension formulation comprising microencapsulated pendimethalin comprising a herbicidally effective amount of pendimethalin being encapsulated within a polymeric wall, said polymeric wall being in-situ formed by an interfacial polymerization reaction occurring between a first phase dispersed in a second phase, at least one of said first and second phases being characterized in comprising a pre-defined amount of at least one alkali or alkaline earth metal salt of an organic acid; and a herbicidally effective amount of a second herbicide.
摘要:
A compound of formula (I), wherein R1 is hydrogen or a hydroxyl protecting group; and R2 and R3 are same or different and are independently selected from halogen or —O—SO2—X; wherein X is —C1-C4 alkyl; C1-C4 alkyl substituted with one or more halogen; or substituted or unsubstituted phenyl wherein said phenyl substituent is selected from halogen, nitro and C1-C4 alkyl; provided that when R3 is bromine, X is not p-toluoyl; and a process for the preparation thereof.
摘要:
This invention relates to a synergistic herbicidal composition comprising Component A comprised of i) 25 to 40% asulam, or its sodium salt; ii) 10 to 20% of a surfactant; iii) 0 to 1% of an antifoam; iv) 0 to 5% adjuvants and auxiliaries; and v) 40 to 65% water; and Component B comprised of trifloxysulfuron, or its herbicidally effective salts; wherein the ratio of Component A to Component B is in range of 80:1 to 380:1 based on active ingredient. The invention furthermore relates to a method of controlling weeds in crops of useful plants, especially in postemergence sugarcane, and to the use of this novel composition for this purpose.
