Binding of paraquat and diquat on melanin
Experimental Eye Research, 1977The binding on melanin of the quaternary dipyridylium salts paraquat and diquat has been studied in vivo in mice by autoradiography and in vitro by reaction with pigment from beef eyes. It was shown that paraquat and diquat were strongly bound on melanin in vivo and in vitro.

Diquat and endothall: Their fates in the environment
1976In recent years, the increasing use of herbicides in the U.S. has been accentuated by the aquatic weed problem caused by eutrophication. Certain herbicides developed mainly for agriculture are being used successfully to control aquatic weed nuisances. Among the herbicides gaining wide acceptance for the control of terrestrial and aquatic vegetation are

DESICCATION OF SUNFLOWER WITH DIQUAT
Canadian Journal of Plant Science, 1985Diquat was applied at 0.3 kg (a.i.)/ha to sunflower (Helianthus annuus L.) at various stages of maturity in a 3-yr study to determine its effects on some agronomic and quality characteristics. The applications effectively hastened drying of the leaves and heads but stem drying was variable.

Photochemical Degradation of Diquat
Nature, 1967DIQUAT as the dibromide (I) is the active constituent of ‘Reglone’* herbicide, which is being used in a wide variety of weed control problems1. It has been shown2,3 that the related bipyridylium herbicide ‘Gramoxone’*, based on the paraquat cation, is subject to significant photochemical degradation in sunlight at certain times of the year; the present

The dipyridylium herbicides, paraquat and diquat
1968Since the discovery of their herbicidal potential in the mid-1950’s, the dipyridylium herbicides 1,1’-dimethyl-4,4’-bipyridinium salts (paraquat) and 6,7-dihydrodipyrido[1,2-a:2’, l’- c]pyrazinediium salts (diquat) have been used extensively for control and management of terrestrial and aquatic vegetation.

DESICCATION OF FLAX WITH DIQUAT
Canadian Journal of Plant Science, 1981Diquat treatments were applied to flax (Linum usitatissimum L.) over a 5-yr period to determine its effect on some agronomic and quality characteristics when applied at 0.28 and 0.56 kg a.i./ha at the 75, 50, 25 and 0% green capsule stages. In most cases the spray applications effectively hastened drying of the plants, eliminating the need for ...

HERBICIDES exert selective effects on soil microorganisms as well as on higher plants, a fact which is implied by reports that certain soil organisms, and in particular bacteria, adapt themselves and are able to decompose chemicals, such as 2,4-dichlorophenoxyacetic acid1, methylchloro-phenoxyacetic acid2, dalapon3, amitrole4, paraquat5 and simazine6 ...
