NOXIOUS ARTHROPOD CONTROL AGENT CONTAINING AMIDE COMPOUND

An object of the present invention is to provide a compound having the controlling activity on a noxious arthropod, and a noxious arthropod controlling agent containing an amide compound of formula (I): wherein X represents a nitrogen atom or a CH group, p represents 0 or 1, A represents a tetrahydrofuranyl group or the like, R1, R2, R3, R4, R5, R6 and R7 represent a hydrogen atom or the like, n represents 1 or 2, Y represents an oxygen atom or the like, m represents any integer of 0 to 7, and Q represents a C1-8 chain hydrocarbon group optionally having a phenyl group or the like, has the excellent noxious arthropod controlling effect.

NUCLEOPHILIC ENHANCEMENT OF BETA-ENDOSULFAN IN AN ENDOSULFAN MIX

The invention relates to a process for the preparation of endosulfan enriched in the ?-isomer thereof (?-endosulfan). The invention also provides a process for enriching the ?-isomer content of a mixture of a- and ?-endosulfan, and to processes for obtaining ?-endosulfan in substantially pure form.

Use of citric acid derivatives as pesticidal adjuvants

The invention provides the use as a pesticidal adjuvant of at least one citric acid derivative and compositions containing the derivative, which has a log octanol-water coefficient (log P) of 2.6 to 11 and an equivalent hydrocarbon (EH) value of 29 to 47. The invention has been shown to enhance the efficacy of a range of pesticides.

Nitro- and cyanoguanidines as selective preemergence herbicides and plant defoliants

There are provided novel nitroguanidine and cyanoguanidine compounds. A method of dessicating and defoliating plants by applying to the foliage thereof certain nitroguanidine or cyanoguanidine compounds and a method for the selective preemergence control of undesirable broadleaf weeds and grasses in the presence of graminaceous crops are disclosed.

Photoinduced Reactions: Part IV - Studies on Photochemical Fate of 6,7,8,9,10,10-Hexachloro-1,5,5a,6,9,9a-hexahydro-6,9-methano-2,4,3-benzodioxathiepin-3-oxide (Endosulphan), an Important Insecticide

The photolysis of the cyclodiene insecticide endosulphan (6,7,8,9,10,10-hexachloro-1,5,5a,6,9,9a-hexahydro-6,9-methano-2,4,3-benzodioxathiepin-3-oxide) has been examined under different conditions, including environmental.Two new photometabolites, photo-α-endosulphan and photo-β-endosulphan have been isolated from α- and β-isomers of endosulphan respectively and characterised on the basis of their 13C NMR spectra and other data.Irradiation in polar solvents gives metabolites similar to those formed under biotic conditions.When exposed to sunlight on plant leaves, α-endosulphane not only forms the photometabolite but also undergoes isomerisation to β-isomer.On the other hand β-isomer is relatively more stable.This explains the relatively longer persistence of β-endosulphan in the environment and may have some significance on their toxicity.

Triplet Sensibilized Isomers of the Insecticide Thiodane

The photoisomerization reactions of cyclodiene insecticide Thiodane were investigated in different solvent systems, with wavelengths above 290 nm.The results show that β-isomer (2) can be converted in the presence of acetone into the α-isomer (1).Photokinetic experiments give sufficient information on the character of the excited state of these compounds. - Key words: Thiodane, Photochemical Reactions, Isomerization
