Embodiment 1

[0024] A betulin plant aphidicide consists of the following components in parts by weight: 50 parts of N-methylpyrrolidone, 10 parts of betulin, 30 parts of turpentine, and 10 parts of Tween 85 with an HLB value of 15.

[0025] The preparation method is as follows: first dissolve betulin with N-methylpyrrolidone, then add Tween 85 and turpentine and mix well.

Embodiment 2

[0027] A betulin plant aphidicide consists of the following components in parts by weight: 50 parts of N-methylpyrrolidone, 5 parts of betulin, 30 parts of turpentine, and 15 parts of Tween 85 with an HLB value of 15.

[0028] The preparation method is as follows: first dissolve betulin with N-methylpyrrolidone, then add Tween 85 and turpentine and mix well.

Embodiment 3

Abstract

The invention discloses an application of betulinol in preparation of an aphicide and the aphicide. Compared with traditional pesticides, the betulinol plant aphicide has the following characteristics and advantages that 1, a large amount of betulinol exists in the nature, especially in plants, the betulinol content is high, the toxicity is low, the betulinol plant aphicide is easy to degrade, and the betulinol plant aphicide is safe to the environment; 2, betulin can be extracted through a supercritical carbon dioxide method, and the extraction method is relatively simple; and 3, betulinol can be dissolved in various solvents due to physical and chemical characteristics, can be easily mixed with other aphid killing components to prepare medicines, and can play a role in improving the aphid killing effect. Experimental results prove that betulin has remarkable contact activity on green peach aphids, and the indoor contact activity on the green peach aphids is greatly improved along with the increase of the concentration. According to the invention, a harmonious pesticide which is safe to human and livestock and environment-friendly is provided, and has profound significance in long-term development of ecological environment, health of human beings, full utilization of environmental resources and comprehensive treatment of diseases.

Description

technical field [0001] The invention relates to the application of betulin in preparing an aphidicide and the aphidicide, which belong to the field of pesticides. Background technique [0002] Peach aphid (Myzus persicae Sülzer), also known as peach red aphid, greasy insect, tobacco aphid, oily man, belongs to Homoptera, Aphididae. My peach aphid has a wide distribution range and occurs in North Korea, Japan, Indonesia, India, North America, Europe, Africa and other places. It is one of the most widely distributed aphids in the world and is distributed in the main peach producing areas of my country. Peach aphid has a wide range of hosts and can feed on more than 400 kinds of plants in more than 50 families, mainly including Rosaceae plants such as peaches and plums, Brassicaceae plants such as rapeseed, and Solanaceae plants such as tobacco and potatoes. Moreover, peach aphid has a strong ability to transmit viruses, and can transmit 115 kinds of plant viruses, accounting ...
