  • Chloramphenicol home made: melting point 229-230 ° C o 1H NMR (300 MHz, CDC1 3 ) ⁇ 10.10 (s, IH, Ph-H), 8.45 (dd, IH, Pyridin-6-H), 7.85 (dd , IH, Pyridin-4-H), 7.37 (dd, IH, Pyridin-5-H), 7.23 (d, IH, Ph-3-H), 7.21 (d, IH, Ph-5-H), 7.13 (s, IH, Pyrazole), 6.20 (d, IH, H), 2.94 (d, 3H, CH 3 ), 2.17 (s, 3H, Ph-CH 3 ).
  • the chemical structure is as follows:
  • the test method is as follows: Determination of in vitro bactericidal activity: The molten AEA medium is cooled to 60 ° C to 70 ° C, and the quantitative agent is added according to the set concentration to prepare a toxic medium containing different doses. After it was sufficiently cooled, the inoculum of 0.5 cm in diameter was inoculated and placed in an incubator for cultivation. The culture was carried out for 10 days in an incubator, and the growth diameter of each treated colony was measured and the inhibition rate was calculated.
  • Determination of in vivo protective activity A live pot assay was used. The test compound was first dissolved in a small amount of acetone and diluted to the desired concentration with water containing 0.1% Tween 80. The spray was applied to the plant test material, and the disease was inoculated 24 hours later. After inoculation, place the plants in a constant temperature and humidity incubator to continue the infection, after the control is fully ill (usually Conduct an assessment survey for a week).
  • In vitro antibacterial activity assay When the concentration of the drug solution is 25 ppm, the inhibition rate of rice blast by compounds 1-4, 2-10, 2-18, 2-31, etc. is more than 50%. The inhibition rate of rice blast with the control agent chlorantranil at 25 ppm was . .
  • the control agent chlorantranil had a control effect on cucumber downy mildew and anthracnose at a dose of 400 ppm.

Abstract

L'invention porte sur des composés anthranilamides représentés par la formule I, possédant une activité insecticide à large spectre. Les substituants dans la formule I sont tels que définis dans la description. A dose faible, les présents composés possèdent une bonne activité contre les lépidoptères nuisibles : pyrale du maïs, pyrale de la canne à sucre, pyrale tordeuse de la pomme, tordeuse des bourgeons de la pomme, lymantride, pyrale des herbes, pyrale du maïs, pyrale du tabac, petite tordeuse des bourgeons, petite mite plutellidae, légionnaire de la betterave, légionnaire asiatique et similaires, notamment la petite mite plutellidae et le légionnaire de la betterave. Les présents composés ont également une activité élevée contre les nuisibles homoptères, comme les pucerons. De plus, certains desdits composés ont une activité puissante comme bactéricides et peuvent être utiles dans la lutte contre la pyriculariose du riz, le mildiou de la tomate, le mildiou du concombre et la pourriture grise des légumes.
