Embodiment 1

[0031] Embodiment 1: prepare the agricultural water solvent of the compound of the present invention

[0032] Weigh raw materials according to weight (unit: g): 6 g each of stilbostemin E and stemanthrene A, Tween-602 g, and water 50 mL.

[0033] Add 50 mL of Tween-60 and heat to 50-60 degrees Celsius, slowly add stilbostemin E and stemanthrene A respectively, and filter to obtain an aqueous solution.

[0034] Agriculture can be used to kill nematodes by diluting 50mL of the prepared aqueous solution to 2000mL with water for spraying or rhizosphere injection.

Embodiment 2

[0035] Embodiment 2: Preparation of capsules of the compound of the present invention

[0036] Each raw material (unit: g) was weighed according to the following weight: 60 g each of stilbostemin E and stemanthrene A.

[0037] Add 100 mL of ethanol to stilbostemin E and stemanthrene A respectively, filter, add 1.8 g of sodium starch glycolate, mix well, spray dry to make granules, and put them into No. 1 capsules to obtain capsules.

Embodiment 3

[0038] Example 3: Preparation of Tablets of Compounds of the Invention

[0039] Each raw material (unit: g) was weighed according to the following weight: 60 g each of stilbostemin E and stemanthrene A.

[0040] Add 100 mL of ethanol to stilbostemin E and stemanthrene A respectively, filter, add 1.8 g of sodium starch glycolate, mix thoroughly, spray dry to make granules, and send to a tablet machine for tableting.

Abstract

The invention relates to the technical field of pesticides and medicines, in particular to application of two compounds in preparing nematocidal drugs. The two compounds disclosed by the invention aresafe and reliable and can effectively prevent and control nematode diseases in agriculture; nematode parasites can be removed for medical use; in addition, the two compounds have no toxic or side effects and drug dependence to a human body, is superior to existing pesticides and medicines, and can be widely used in the preparation of the nematocidal drugs.

Description

technical field [0001] The invention relates to the technical fields of pesticides and medicines, in particular to the application of two compounds in the preparation of nematicides. Background technique [0002] Nematode refers to the general term belonging to the nematode animal phylum. There are many kinds of records, which can be seen everywhere in the world. Many of them are parasitic. Among them, there are as many as 25 kinds of parasitic nematodes recorded in my country, and the more popular ones are roundworms, pinworms and hookworms. . With the improvement of medical and sanitation conditions, the infection rate of soil-transmitted nematodes in my country has been reduced from 20.88% to 3.12% in 2005-2013, but it still poses a great threat to people's health. And agricultural and forestry nematodes are also very harmful, resulting in reduced agricultural production (such as root-knot nematode, which is estimated to cause global crop losses of 100 million US dollars)...
