Embodiment 1

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

[0077] Paulanne 2.1%, Tea Saponin 0.9%, Methanol 10%, Cyclohexane 9%, Ethyl Acetate 8%, Cyclohexanone 25%, Agricultural Milk 5004%, Agricultural Milk 7008%, AEO-710%, GP3300 .5%, glycerol 0.5%, the balance of water. According to the proportioning ratio, savoryne and tea saponin are dissolved in methanol, cyclohexane and ethyl acetate, and after mixing, other components are added to prepare the microemulsion.

Embodiment 2

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

[0079] Methoprene 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·pyridoxone wettable powder, the weight ratio of each component is:

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

Abstract

The invention discloses a pesticide by mixing tea saponin with an insect growth regulator. The mixed pesticide preparation comprises the following materials in percentage by weight: 0.01-80 percent of tea saponin, 0.5-80 percent of insect growth regulator and the balance of additives and can be prepared into missible oil, wettable powder, micro-emulsion, suspending agents, suspending emulsion or aqueous emulsion. By compounding the insect growth regulator with the tea saponin, the invention has notable synergy and obviously enhanced insecticidal activity than a single preparation, and takes the effect of simultaneously killing a plurality of insects by one pesticide, thereby lessening the labor and material investment in the insect-preventing process and improving the production benefits while obviously reducing the cost on the premise of ensuring the pesticide action. The invention has a plurality of preparation forms, simple preparation method and higher popularization value.

Description

technical field [0001] The invention belongs to the technical field of agricultural insecticides, and in particular relates to an insecticide mixed with tea saponin and an insect growth regulator. 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 suc...
