Embodiment 1
[0030] Take by weighing 12g of bucchini alcohol, dissolve with 1g acetone solution, add 1g Tween-80, dissolve, according to routine process, make bucchini alcohol insecticide, then in the prepared bucchini alcohol insecticide Add acetone to dilute, so that the concentration of bocicol, that is, the bulk drug, is 7%. Finally, the biological activity of the diluted potiole alcohol insecticide was measured indoors on beet armyworm larvae by spot method. After 24 hours, the number of dead and alive insects in each treatment was investigated, and the control effect was 77.8%.
Embodiment 2
[0032] Take by weighing 18g of bucchini alcohol, dissolve with 96g ethyl acetate, add 53g of emulsifying agent etc. therein, according to routine process, make bucchini alcohol insecticide, then in the buccal alcohol insecticide made Add acetone to dilute, so that the concentration of bocicol, that is, the bulk drug, is 12%. Finally, the biological activity of beet armyworm was measured indoors with the diluted potiole alcohol insecticide by spot method. After 24 hours, the number of dead and alive insects in each treatment was investigated, and the control effect was 94.6%.
Embodiment 3
[0034] Take by weighing 40g of bucchini alcohol, dissolve with 28g ethanol, add emulsifier Span-20 etc. 12g therein, according to routine process, make bucchini alcohol insecticide, then in the bucchini alcohol insecticide of making Add acetone to dilute the agent, so that the concentration of bocicol, the bulk drug, is 31%. Finally, the diluted potiole alcohol insecticide was used for bioassay on beet armyworm larvae by spot method, and the mortality rate was counted after 24 hours, and the control effect was 99.2%.

Abstract
The invention provides application of patchouli alcohol. The patchouli alcohol is used for preparing a pesticide for controlling noctuidae pests. The invention further provides the patchouli alcohol pesticide which is prepared from the following components in percentage by mass: 0.05 percent to 99 percent of patchouli alcohol, and 1 percent to 99.95 percent of conventional ingredients. When in use, water is added into the patchouli alcohol pesticide under stirring at the room temperature, and the patchouli alcohol pesticide is diluted until the patchouli alcohol only accounts for 0.5 to 40 percent by weight of the concentration so as to be sprayed and applied. The invention firstly discovers that the patchouli alcohol has insecticide biological activity and is prepared into the pesticide for controlling the noctuidae pests for the first time. The pesticide adopts the patchouli alcohol as an active compound so as to be a natural product, has the characteristics such as low toxicity andeasiness in degradation, is friendly to human beings, animals and an ecological environment, and is the safe pesticide.
Description
technical field [0001] The invention relates to an insecticide in the technical field of pesticides, in particular to a use of bocicol as an insecticide for controlling Noctuidae pests and the insecticide. Background technique [0002] Noctuidae is the largest family of Lepidoptera insects. This family contains more than 20,000 kinds of insects. Many species can harm crops. They are a very important agricultural pest in the world. Among them, beet armyworm, Spodoptera litura, Noctuidae pests represented by cotton bollworm are mostly omnivorous pests, which can cause serious damage to many crops such as vegetables, fruit trees, flowers, and food crops. In addition, the Spodoptera frugiperda, which originated in the tropical and subtropical regions of America, which invaded my country in January 2019, is also a pest of the Noctuidae family. This type of pest has the characteristics of strong migratory ability, wide host range, heavy damage, and difficult control. , is an impor...
