Insecticidic agent

专利摘要:
1449967 Thiophosphoric acid esters CIBAGEIGY AG 14 March 1974 [15 March 1973 30 Jan 1974] 11455/74 Heading C2P The invention comprises compounds of the general formula wherein R 1 is methyl or ethyl, R 2 is n-propyl, isopropyl, isobutyl, secbutyl, or n-amyl, R 3 is H or methyl, X is H, Cl, Br, F, CH 3 , CH 3 S, CH 3 S(O), CH 3 O or acetyl, and n is 1, 2 or 3. They may be obtained by the following reaction procedures where Hal is halogen and Me is an alkali metal, ammonium or alkylammonium. In some eases copper or copper chloride should be present as catalysts. The compounds have pesticidal properties and may be used as active ingredients in conventional pesticidal compositions which may also contain other pesticides.

(54) INSECTICIDAL. MEANS
; :. ; I -,. The invention relates to plant protection products, namely, insecticides containing O-ethyl-0-aryl-8-alkyl-thiophosphoric acid esters as a1 of the active component. A known agent whose active starting point is O-alkyl; -8-alkyl-0- (lower alkyl) -alkylcarboyl nylphenylthiophosphoric acid esters tU. Closer to the invention is an agent whose active ingredients are O-ethyl-S-propyl-O- (methylthio) alkylphenylthiophosphoric acid 2 esters. However, the known compounds have insufficient insecticidal activity. The aim of the invention is to find an insecticidal agent having only a higher activity than the known ones. In Kazan, the goal is achieved by using the compounds of the general formula where R is ethyl; R. - and from o-propyl, isoi sec-butl, n-amyl; RJ is hydrogen, methyl; X is hydrogen, halogen, methyl, methylthio, methylsulfinyl, m tox, acyl; P -1-3-. -.,: In a weight ratio of 0.5 to 95 wt.%, As well as an additive selected from the group of diluent, dispersant, wetting agent. Usage forms are common: dusts, emulsion concentrates, granulates, dispersions, sprayable preparations, solutions, suspensions. They are prepared by methods common in the preparation of pesticide formulations. The proposed compounds are obtained by reacting compounds of the formula "" s. with phenolism foemule
in the presence of an acid binding agent, corresponding to the corresponding alkali phenol. In the table. 1 shows the compounds that can be obtained in the above mentioned manner.,
An example. Prolonged insecticidal gastrointestinal dovodye action .-,.: -,. :.
Cotton infestations are sprayed with a 05% aqueous emulsion containing a valid start (consisting of 1 P% emulsifiable concentrate) ...
After drying, each plant is covered with larvae of L Spodoptera ijittoritlis or Heliothis virescens. Percentage destruction occurs after 2, 4, 24, and 48 hours. In the case of a 100% killing, after 48 hours, the plants are again covered with new EXTRA PEST and continue to be killed at the same time intervals (3 hN5

up to 48 hours. If they again achieve 100% killing, then the test is carried out again after 8 days.
The test was carried out at 24 ° C and 60% relative humidity; known compounds were used as comparative compounds.
