Coleus plants (approximate height 29 cm) in 6-inch pots which have been infected approximately 4 weeks before the treatment with citrus mealybug Pseudococcus citri (PSECCI) are drenched, in three replications, with an active substance solution containing the active substance I-4 (cis isomer, formulation: 240 SC) and, by way of comparison, with the commercial standard imidacloprid (240 SC) at the application rate stated. The greenhouse temperature is 29° C. The test is evaluated 7, 14, 21 and 28 days after the treatment by determining the efficacy with the aid of Abbott's formula.
Coleus plants (approximate height 29 cm) in 6-inch pots which have been infected approximately 4 weeks before the beginning of the experiment with Madeira mealybug (Phenacoccus madeirensis) are drenched, in three replications, with an active substance solution containing the active substance I-4 (cis isomer, formulation: 240 SC) and, by way of comparison, with the commercial standard imidacloprid (240 SC) at the application rate stated. The greenhouse temperature is 29° C. The test is evaluated 7, 14, 21 and 28 days after the treatment by determining the efficacy with the aid of Abbott's formula.

Furthermore very especially preferred is the control of the following species from the family of the leaf-mining flies (Agromyzidae) in the following crops:
Liriomyza brassicae
Liriomyza bryoniae
Liriomyza cepae
Liriomyza chilensis
Liriomyza hunidobrensis
Liriomyza sativae
Liriomyza trifolie
Liriomyza quadrata
Pegomya hyoscyami
Pegomya spinaciae
Plots approximately 2×5 m in size which contain bell pepper plants are treated, in three replications, against Liriomyza sp. The active substance example (I-4) cis isomer (240 SC) is drenched in an active substance solution at the application rate stated. The water application rate is 700 l/ha. Three treatments are carried out at intervals of 7 and 14 days. The test is evaluated in each case 7 days after the 2nd and 3rd treatment and 14 days after the 3rd treatment by scoring the kill rate of the larvae in the leaves.
Plots approximately 2×5 m in size which contain bell pepper plants are treated, in three replications, against Bemisia sp. The active substance example (I-4) cis isomer (240 SC) is drenched in an active substance solution at the application rate stated. The water application rate is 700 l/ha. Three treatments are carried out at intervals of 7 and 14 days. The test is evaluated in each case 7, 14, 21 and 28 days after the 3rd treatment by scoring the kill rate of the larvae on the leaves.
Furthermore very especially preferred is the control of the following species from the family of foliar nematodes (Aphelenchoididae) in the following crops:
Aphelenchoides ritzemabosi in ornamentals and strawberries
Aphylenchoides fragariae
Aphylenchoides besseyi
Aphylenchoides blastophthorus
The bulbs of 15 lily plants cv. “L.A. Glow” (growth stage 14/16) are dipped, in four replications, into an active substance solution containing the active substance I-4 (cis isomer, formulation: 240 SC) at the concentrations stated and subsequently planted into boxes 40×60 cm in size. The bulbs came from a field which was homogeneously infested with the foliar nematode Aphelenchoides fragariae. The number of infested plants is determined by examining leaves under the microscope for foliar nematodes 92 days after the dip treatment.
