example 1
To a solution, cooled to 10 C, of 37 g of 3 hydroxydiphenyl ether and 22 g of triethylamine in 500 ml of absolute diethyl ether, 41 g of O-ethyl-S-n-propylthiolphosphoric acid chloride in 60 ml of diethyl ether are added dropwise with stirring so quickly that the temperature does not exceed 30 "-C .
The mixture is stirred for a further two hours at 20-25 ° C. and this is added
Mixture with further stirring with 300 ml ice water. The organic phase is separated off, shaken once with water and twice with ice-cold 5% sodium hydroxide solution and then washed neutral with water. Now the ether phase is treated with activated charcoal, filtered, dried and the solvent evaporated. The above residue is dried for three hours at 70 ° C. and 0.1 torr. The compound of the formula is obtained
EMI3.1
as a yellowish, non-distillable, viscous oil with a refraction of nn20 = 1. <'t2.

Example 2 A. Insecticidal feed poison effect
Cotton plants and potato plants were sprayed with a 0.05% aqueous active substance emulsion (obtained from a 10% emulsifiable concentrate).
After the covering had dried on, the cotton plants were populated with Spodoptera littoralis or Heliothis virescens larvae L3 and the potato plants with Colorado beetle larvae (Leptinotarsa decemlineata). The experiment was carried out at 24 ° C. and 60 ° C. relative humidity.
In the above test, the compounds according to Example 1 showed a good insecticidal feeding poison action against Spodop tera, Heliothis and Leptinotarsa decemlineata larvae.
B Systemic insecticidal effect
To determine the systemic effect, rooted bean plants (Vicia faba) were placed in a 0.01% strength aqueous active ingredient solution (obtained from a 10% strength emulsifiable concentrate). After 24 hours, aphids (Aphis fabae) were placed on the above-ground parts of the plant. The animals were protected from contact and gas effects by a special device. The experiment was carried out at 24 C and 70% relative humidity.
The compounds according to Example 1 acted systemically against Aphis fabae in the above test.
Example 3 Action against Chilo suppressalis
6 rice plants of the Caloro variety were transplanted into plastic pots with an upper diameter of 17 cm and raised to a height of about 60 cm. The infestation with Chilo suppressalis larvae (L1; 3-4 mm long) took place 2 days after the addition of the active ingredient in granulate form (application rate 8 kg active ingredient per hectare) into the paddy water. The insecticidal activity was evaluated 10 days after the granules had been added.
The compounds according to Example 1 were effective against Chilo suppressalis in the above test.
Example 4 Action against ticks A. Rhipicephalus bursa
5 adult ticks or 50 tick larvae were counted in a glass tube and immersed for 1 to 2 minutes in 2 ml of an aqueous emulsion from a dilution series with 100, 10, 1 or 0.1 ppm test substance each. The tube was then closed with a standardized cotton ball and turned upside down so that the active ingredient emulsion could be absorbed by the cotton wool.
The evaluation was carried out after 2 weeks for the adults and after 2 days for the larvae. Two repetitions were run for each attempt.
B. Boophilus microplus (larvae)
With an analogous dilution series as in test A, 20 sensitive resp. OP-resistant larval experiments were carried out. (The resistance refers to the tolerance of Diazinon.)
The compounds according to Example 1 were active in these tests against adults and larvae of Rhipicephalus bursa and sensitive, respectively. OP-resistant larvae of Boophilus microplus.
Example 5 Acaricidal Effect
Phaseolus vulgaris (plants) were covered with an infected piece of leaf from a mass cultivation of Tetranychus urticae 12 hours before the test for acaricidal activity. The overflowing mobile stages were dusted with the emulsified test preparations from a chromatography atomizer so that the spray mixture did not run off. After two to 7 days, larvae, adults, and eggs were scored under the binocular for living and dead individuals.
During the holding time, the treated plants stood in greenhouse cabins at 25 C.
In the above test, the compounds according to Example 1 were effective against adults, larvae and eggs of Tetranychus urticae.
