Embodiment 1

[0021] Weigh spinosyn and flonicamid, and prepare spinosyn and flonicamid emulsifiable concentrate with a mass percentage of 40% of spinosyn and flonicamid respectively by using conventional preparation methods. For specific ratios, see Table 1, 2.

[0022] The indoor synergistic bioassay was carried out by dipping leaves and insects, and the resistant diamondback moth was selected as the target pest, and each treatment was repeated 3 times, and LC 50 Calculate the co-toxicity coefficient according to Sun Yunpei's method:

[0023] Table 1. Indoor toxicity determination of spinosad and flonicamid synergistic insecticidal composition and its single agent against resistant diamondback moth:

[0024]

[0025] The data in the table shows that spinosad and flonicamid have a synergistic effect on Plutella xylostella after mixing, and the co-toxicity coefficients of the three ratios listed in the table are all greater than 120, so the mixed spinosyn and flonicamid With a signific...

Embodiment 2

[0039] Weigh 2g of spinosad and 8g of flonicamid and dissolve it in 8g of solvent oil, then add 1g of ethylene glycol and 5g of emulsifier 600#, and stir evenly. Slowly pour the above solution into the remaining amount of water, and fully stir to prepare a 10% spinosad-fluonicamid emulsion in water.

Embodiment 3

[0041] Weigh 8g of spinosad, 2g of flonicamid, 8g of sodium lignosulfonate, 2g of sodium lauryl sulfate, 5g of ammonium sulfate, 5g of polyvinyl alcohol, 2g of borax, and 28g of kaolin, and disperse the above raw materials into granules by water 10% spinosyn · flonicamid water dispersible granules were prepared by the method.

Abstract

The invention relates to a synergistic insecticidal composition containing spinosad and flonicamid, and an application thereof. The synergistic insecticidal composition employs spinosad and flonicamid as main effective components, wherein a weight ratio of spinosad to flonicamid is 0.1-80 : 0.1-50. The insecticidal composition can produce a relatively high synergistic interaction effect, overcomes or delays insect resistance, enlarges prevention spectrum, has fast insecticidal speed and reduces pesticide cost. The insecticidal composition can be used for preventing lepidoptera pests and has an effect obviously higher than that of a single dosage.

Description

technical field [0001] The invention belongs to the field of pesticides, and in particular relates to a synergistic insecticidal composition containing spinosad and flonicamid and its application. Background technique [0002] Spinosad compounds are the first new natural insecticides developed by Dow AgroSciences. The secondary metabolites obtained by fermentation, the active ingredients are spinosyns spinosyn A and spinosyn D. [0003] [0004] Spinosad can effectively control Lepidoptera, Diptera and Thysanoptera pests, and can also control certain pests in Coleoptera and Orthoptera that eat leaves in large quantities. [0005] Flunicamid (flonicamid, flunicotamid), chemical name: N-cyanomethyl. (trifluoromethyl) nicotinamide. Flunicamid is a low-toxicity insecticide. This agent is effective against various piercing-sucking mouthparts pests, and has good penetration. It can penetrate from roots to stems and leaves, but the penetration from leaves to stems and roots ...
