Embodiment 1

[0076] Embodiment 1 prepares 3% tea saponin · flonicamid microemulsion, the weight ratio of each component is:

[0077] Flunicamid 2.1%, Tea Saponin 0.9%, Methanol 10%, Cyclohexane 9%, Ethyl Acetate 8%, Cyclohexanone 25%, Nongru 5004%, Nongru 7008%, AEO-710%, GP3300.5%, glycerol 0.5%, the balance water. Dissolving flonicamid and tea saponin in methanol, cyclohexane and ethyl acetate according to the ratio, and adding other ingredients after mixing to prepare microemulsion.

Embodiment 2

[0078] Embodiment 2: prepare 5% tea saponin · cornidine emulsifiable concentrate, the weight ratio of each component is:

[0079] Cornidine 3.5%; tea saponin 1.5%; surfactant Nongru 500 10%, Nongru 700 10%; organic solvent cyclohexane 20%, ethyl acetate 10%, DMF 10%, dichloromethane 10% %; cosolvent methanol 5%; stabilizer castor oil 5%; anti-photolysis agent epoxidized soybean oil 5%; penetrant laurocaprison 10%. Put each component into the preparation kettle and mix thoroughly.

Embodiment 3

[0080] Embodiment 3: prepare 80.5% tea saponin dinotefuran wettable powder, the weight ratio of each component is:

[0081] Dinotefuran 0.5%; tea saponin 80%; wetting agent sodium lauryl sulfate 3%; dispersant lignin 2.5%; filler diatomaceous earth 14%. The dinotefuran and the tea saponin original drug are air-pulverized according to the proportion, and then added to the mixer, and the auxiliary agents are respectively added into the mixer according to the proportion, and the mixture is fully stirred evenly to obtain the product.

Abstract

The invention discloses a mixed insecticide of tea saponin and a neonicotine insecticide. The mixed pesticide preparation comprises the components in percent by weight: 0.01% to 80% of tea saponin, 0.5% to 80% of neonicotine insecticide and the balance of assistant agent. The mixed pesticide preparation can be prepared into missible oil, wettable powder, microemulsion, a suspension agent, a suspension emulsion or a water emulsion. The neonicotine insecticide and the tea saponin are selected for mixing, therefore, the mixed insecticide has obvious synergy; compared with a single agent, insecticidal activity is obviously enhanced; and the mixed insecticide has multiple treating effects on various pests, thereby reducing manpower and material utilization in the processes of controlling the pests and enhancing production benefits. At the same time, on the premise of ensuring medical effects, the invention remarkably reduces the cost. The mixed insecticide has various preparations, simple preparation method and high popularization value.

Description

technical field [0001] The invention relates to an agricultural insecticide, in particular to an insecticide mixed with tea saponin and neonicotinoid insecticides. Background technique [0002] Due to the long-term and large-scale irrational use of chemical pesticides, as well as the inherent shortcomings of some pesticides, the "3R" problem has been caused by pests. Therefore, looking for biologically active substances and researching and developing new biopesticides based on natural products have attracted much attention at home and abroad, among which botanical pesticides are the most eye-catching category. The development of botanical pesticides, the mixing of botanical pesticides and chemical pesticides, and the mixing of botanical pesticides and microbial pesticides are the frontiers and hotspots of pesticide research in the world. [0003] Tea saponin (Tea saponin) is a plant insecticide extracted from the seeds of Camellia plants such as tea seed cake and tea cake a...
