Embodiment 1

[0016] Embodiment 1. Solidago canadensis oil is dissolved in acetone to form a medicinal solution, and the concentration of goldenrod canada oil in the medicinal solution is 0.4g / 100ml. Use this medicinal liquid to prevent and control bean spider mites in soybean fields, and spray on the surface of bean stems, leaves and other organs, so that the medicinal liquid is distributed on the surface. According to the investigation results, the corrected acaricidal effect reaches 86.3%.

[0017] Corrected acaricidal effect = 1-[(amount of mite in treatment area × amount of acarid in control area before treatment) / (amount of acarid in treatment area × amount of acarid in control area)] × 100%

Embodiment 2

[0018] Embodiment 2, dissolving solidago canadensis oil in acetone to form a medicinal liquid, the concentration of goldenrod canada oil in the medicinal liquid is 0.8mg / 100ml. Use this medicinal liquid to prevent and control spider mites in cotton fields, and spray on the surface of cotton plant stems, leaves and other organs, so that the medicinal liquid is distributed on the surface. According to the investigation results, the corrected acaricidal effect reaches 92.1%.

Embodiment 3

[0019] Embodiment 3, dissolving solidago canadensis oil in acetone to form a medicinal liquid, the concentration of goldenrod canada oil in the medicinal liquid is 2g / 100ml. The medicinal liquid is used to prevent and control spider mites in soybean fields, and sprayed on the surface of soybean stems, leaves and other organs, so that the medicinal liquid is distributed on the surface of the plants. According to the investigation results, the corrected acaricidal effect reaches 100%.

Abstract

The invention discloses a Canadian flouve oil as the application of acaricide. The Canadian flouve oil comes from the plants and will not produce pollution to the human and the environment; the invention is a novel active substance which has toxic effects to the agricultural acarus.

Description

technical field [0001] The present invention relates to the application of goldenrod canadensis oil, especially as an acaricide. Background technique [0002] According to their sources, pesticides can be divided into three categories: biological sources, mineral sources and chemical synthesis. There are few types of mineral source pesticides, and the development prospects are not great. Chemical pesticides have their high efficiency and can play a role when a large number of pests and diseases occur; however, the "three Rs" problems generated during the use of chemical pesticides, that is, residues, drug resistance and pest re-infestation are becoming more and more serious. The problem of environmental pollution is also becoming more and more serious. According to statistics from the United Nations Environment Program, 2 million people suffer from acute pesticide poisoning every year in the world, and about 40,000 of them die. In some places, the amount of pesticide resid...
