Problems solved by technology

However, the use of organophosphorus insecticides alone is very easy to produce resistance and the toxicity of this type of pesticides is high
[0006] At present, there is no technical report on the technical scheme for the combined use of tea saponin and organophosphorus insecticides

Embodiment 1

[0076] In Example 1, a 3% tea saponin·trichlorfon microemulsion was prepared, and the weight ratio of each component was:

[0077] Trichlorfon 2.1%, tea saponin 0.9%, methanol 10%, cyclohexane 9%, ethyl acetate 8%, cyclohexanone 25%, agricultural milk 500 4%, agricultural milk 700 8%, AEO-7 10 %, GP3300.5%, glycerol 0.5%, the balance water. Dissolve trichlorfon and tea saponin in methanol, cyclohexane, and ethyl acetate according to the ratio, mix and add other ingredients to prepare a microemulsion.

Embodiment 2

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

[0079] Pythion 3.5%; tea saponin 1.5%; surfactant Nongru 500 is 10%, Nongru 700 is 10%; organic solvent cyclohexane 20%, ethyl acetate 10%, DMF 10%, methylene chloride 10%; cosolvent methanol 5%; stabilizer castor oil 5%; anti-photolytic agent epoxidized soybean oil 5%; penetrating agent laurin 10%. Put each component into the mixing kettle and mix thoroughly.

Embodiment 3

[0080] Example 3: Preparation of 80.5% tea saponin·malathion wettable powder, the weight ratio of each component is:

[0081] Malathion 0.5%; tea saponin 80%; wetting agent sodium lauryl sulfate 3%; dispersant lignin 2.5%; filler 14% diatomaceous earth. According to the ratio, malathion and tea saponin are jet-pulverized and added to the mixer, and the additives are added to the mixer according to the ratio, and the mixture is fully stirred to obtain it;

Abstract

The invention discloses a mixed insecticide of tea saponin and an organophosphate insecticide. The mixed pesticide preparation comprises the components in percent by weight: 0.01% to 80% of tea saponin, 0.5% to 80% of organophosphate 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 organophosphate 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 belongs to the technical field of agricultural insecticides, and specifically relates to an insecticide mixed with tea saponin and organophosphorus insecticides. Background technique [0002] Due to the long-term and large-scale unreasonable use of chemical pesticides, as well as the inherent shortcomings of certain pesticides, the problem of "3R" in pests has been caused. Therefore, looking for biologically active substances and researching and developing new biological pesticides for natural products have attracted much attention at home and abroad. Among them, plant-derived pesticides are the most eye-catching category. The development of botanical pesticides, the blending of botanical pesticides and chemical pesticides, and the blending 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 Camel...
