Herbicide membranes

Bleaching Herbicides. Membrane-based modes of herbicidal action relevant to photosynthesis (37) include those of inhibitors of carotenoid biosynthesis, eg, norflura2on, diftmon, y -phenoxyben2amines inhibitors of chlorophyll biosynthesis, eg, oxadia2on, DTP or... [Pg.43]

Other auxin-like herbicides (2,48) include the chlorobenzoic acids, eg, dicamba and chloramben, and miscellaneous compounds such as picloram, a substituted picolinic acid, and naptalam (see Table 1). Naptalam is not halogenated and is reported to function as an antiauxin, competitively blocking lAA action (199). TIBA is an antiauxin used in receptor site and other plant growth studies at the molecular level (201). Diclofop-methyl and diclofop are also potent, rapid inhibitors of auxin-stimulated response in monocots (93,94). Diclofop is reported to act as a proton ionophore, dissipating cell membrane potential and perturbing membrane functions. [Pg.46]

Microencapsulation means the envelopment of liquid droplets or solid particles with natural or synthetic polymers.The encapsulation of a substance with a polymer membrane is undertaken for various reasons, for example, as protection against moisture, or to obtain delayed dissolution of fertilizers, herbicides, or drugs by microencapsulation with semipermeable membranes. [Pg.295]

Ozone changes plant cell membrane (17, 18) and chloroplast membrane permeability (19). Loss of membrane integrity is also caused by plant pathogens (20), drought (21), herbicides (22) and frost (21). [Pg.98]

B. Spills cause acute high-dose exposures. The symptoms are referable to an acute high exposure to an organochlorine or pyrethroid insecticide. While organochlorine pesticides are not used in this country, they are manufactured for export. An acute high exposure to herbicide would be primarily irritation of skin and mucous membranes. The solvents in printing ink would cause CNS depression. [Pg.71]
