  • the active ingredient compounds were formulated separately into individual solutions of Pymetrozine and Triflumezopyrim.
  • a mixture was prepared using the same solutions of Pymetrozine and Triflumezopyrim at different weight ratios from 7:1 to 9:1.
  • Insecticide applications were made to 2- week-old rice plants using a turntable spray applicator (360 l/ha, 18 ml solution, 2 bar pressure for 12 seconds). After the spray solution had dried (approximately 3 hours) each plant was infested with approximately 30 Nilaparvata lugens N4 nymphs. Plants and insects were contained within a sealed plastic cylinder. Insect mortality was assessed at 1 and 3 days after infestation.
  • Results from the tests outlined above are as set forth in Table 1. These data show that a faster response in terms of pesticidal activity is observed for the combination of Pymetrozine and Triflumezopyrim against Nilaparvata lugens with weight ratios from 7:1 to 9:1 for the compositions C1 to C3. After only 1 day from the application, the combination of Pymetrozine and Triflumezopyrim shows a very high control of Nilaparvata lugens, advantageously at low weight ratios from 7:1 to 9:1 , whilst the individual active ingredients show no pesticidal activity or lower pesticidal activity under the same conditions.
