Example Embodiment

[0019] Example 1: 41% afidopyropen·pymetrozine suspension (afidopyropen: pymetrozine=40:1)

[0020] It is prepared according to the conventional process, including 40g afidopyropen, 1g pymetrozine, 4g sodium lignosulfonate (dispersant), 4g ethylene glycol (antifreeze), 3g bentonite (thickener), and organosilicone (defoamer) ) 3g, make up to 100g with deionized water.

[0021] In this embodiment, the weight ratio of afidopyropen and pymetrozine can be changed between 40:1 and 1:40 to form a new embodiment.

Example Embodiment

[0022] Example 2: 60% afidopyropen·pymetrozine water dispersible granules (afidopyropen: pymetrozine=1:5)

[0023] Prepared according to the conventional process, afidopyropen 10g, pymetrozine 50g, sodium alkyl naphthalene sulfonate (dispersant) 5g, sodium lignosulfonate (dispersant) 7g, sodium lauryl sulfate (wetting agent) 2g, sulfuric acid Ammonium (disintegrant) 5g, light calcium carbonate (filler) make up to 100g.

[0024] In this embodiment, the weight ratio of afidopyropen and pymetrozine can be changed between 40:1 and 1:40 to form a new embodiment.

Example Embodiment

[0025] Example 3: 55% afidopyropen·pymetrozine wettable powder (afidopyropen: pymetrozine = 10:1)

[0026] afidopyropen 50g, pymetrozine 5g, sodium lauryl sulfate (wetting agent) 2g, sodium lignosulfonate (dispersant) 3g, NNO (dispersant) 5g, kaolin make up to 100g.

[0027] In this embodiment, the weight ratio of afidopyropen and pymetrozine can be changed between 40:1 and 1:40 to form a new embodiment.

Abstract

The invention discloses a synergistic pesticidal composition. The synergistic pesticidal composition has the active components of afidopyropen and pymetrozine, wherein the mass ratio of the afidopyropen to the pymetrozine is 1:80 to 80:1. The synergistic pesticidal composition has a significant synergistic effect, has significantly-enhanced pesticidal activity compared with a single agent, and has a very good control effect on planthoppers, leafhoppers, whiteflies, thrips and other pests.

Description

technical field [0001] The invention relates to a synergistic insecticidal composition containing two active ingredients and its application. Background technique [0002] Afidopyropen (test code ME5343) is a new type of insecticide jointly researched and developed by Japan's Meiji Pharmaceutical Co., Ltd. and Japan's Kitasato Research Institute. This product is a new structure and has a new mechanism of action, can be used for vegetables, fruit trees, vines, row crops and ornamental plants, etc., against sucking mouthparts pests such as aphids, planthoppers, scale insects and leafhoppers efficient. [0003] Pymetrozine, common name in English: Pymetrozine, is a triazone insecticide with good systemic activity and is effective against aphids, planthoppers and other Homopteran pests. The disadvantage of pymetrozine is that it has no direct lethal effect on pests and its effect is slow. [0004] At present, there is no technical report on the technical scheme for the combin...
