Embodiment 1

[0076] Embodiment 1 prepares 3% tea saponin emamectin microemulsion, the weight proportion of each component is:

[0077] Emamectin 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. Emamectin and tea saponin are dissolved in methanol, cyclohexane and ethyl acetate according to the proportion, and after mixing, other components are added to prepare the microemulsion.

Embodiment 2

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

[0079] 3.5% of pyrimaben; 1.5% of tea saponin; 10% of surfactant Nongru 500, 10% of Nongru 700; 20% of organic solvent cyclohexane, 10% of ethyl acetate, DMF10%, 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 · pyridaben wettable powder, the weight ratio of each component is:

[0081] Pyridaben 0.5%; tea saponin 80%; wetting agent sodium lauryl sulfate 3%; dispersant lignin 2.5%; filler diatomaceous earth 14%. The pyridaben 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.

Abstract

The invention discloses a mixed insecticide of tea saponin and an acaricide. The mixed pesticide preparation comprises the components in percent by weight: 0.01% to 80% of tea saponin, 0.5% to 80% of acaricide 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 acaricide 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 control process 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 acaricide. Background technique [0002] Judging from the currently used acaricides, although most of them are high-efficiency, low-toxic compounds and are relatively easy to decompose, most of them are nerve agents, and their toxicity to mammals cannot be ignored, and they also have certain effects on the environment. Influence, and at the same time, pest mites are prone to develop resistance. Due to the long-term and large-scale irrational use of chemical acaricides, as well as the inherent shortcomings of some agents, pest mites have developed resistance. In the long run, the research and development of acaricides is moving towards new non-biocide (insect hormone) compounds and biological compounds to solve the problems of their toxicity to animals, pollution to the environment, and drug resistance of harmful mites. Moreover, the cost o...
