Persistence of pesticides in soil leachates: effect of pH, ultraviolet irradiation and temperature: Persistence of pesticides in soil leachates: effect of pH, ultraviolet irradiation and temperature. Elbeit, I. O. D.; Cotton, D. E.; Wheelock, V. (Plant Prot. Dep., Garyounis Univ., AlBayda, Libya). Int. J. Environ. Stud., 21(3-4), 251-9 (English) 1983. CODEN: IJEVAW. ISSN: 0020-7233. DOCUMENT TYPE: Journal CA Section: 5 (Agrochemical Bioregulators) Section cross-reference(s): 19 The effects of pH, UV irradn., and temp.There are some commonly used reagents with their cas registry numbers 60-57-1 and 58-89-9 in this article. on the persistence and breakdown of dieldrin [60-57-1] endosulfan [115-29-7], g-HCH [58-89-9], and pyrolan [87-47-8] were studied in leachates from a loam soil. Except for dieldrin which remained exceptionally stable throughout the pH range, persistence of pesticides decreased progressively as pH increased. After exposure to UV irradn., dieldrin was broken down in activated charcoal. Pesticide losses from covered leachates incubated at different temps. increased with increasing temps. .

Karanja oil and its components as synergists to insecticides: Karanja oil and its components as synergists to insecticides. Sighamony, S.; Naidu, M. B.; Osmani, Z. (Entomol. 87-47-8 and 119-38-0 are cas registry numbers. These chemicals are also mentioned in this article. Div., Reg. Res. Lab., Hyderabad 500 009, India). Int. Pest Control, 25(4), 120-1 (English) 1983. CODEN: IPCLBZ. ISSN: 0020-8256. DOCUMENT TYPE: Journal CA Section: 5 (Agrochemical Bioregulators) To avoid insect resistance and environmentally harmful insecticidal residues, certain vegetable oils can be used as synergists against insect species. Oil of Pongamia glabra and its constituent compds. karanjin [521-88-0] and pongamol [484-33-3] were mixed sep. with the insecticides Isolan [119-38-0], Pyrolan [87-47-8], Sevin [63-25-2], Endrin [72-20-8] and heptachlor [76-44-8], and tested topically against male and female houseflies and red cotton bugs. Insecticides in combination with the oil and its components produced high mortality compared to the insecticides alone. Thus, karanja oil, karanjin and pongamol synergize the above insecticides against both insect. Karanjin and pongamol exhibited a higher level of synergism that the untreated oil. .
