Embodiment 1

[0032] Embodiment 1: prepare the agricultural water solvent of the compound of the present invention

[0033] Weigh raw materials according to weight (unit: g): 3′-(4-hydroxyphenyl)-propanol-benzoate and 4-hydroxycinnamic acid methyl ester 6g each, Tween-602g two parts, water 50mL two parts .

[0034] Add Tween-60 into 50 mL of water and heat to 50-60 degrees Celsius, slowly add 3'-(4-hydroxyphenyl)-propanol-benzoate and methyl 4-hydroxycinnamate, and filter to obtain an aqueous solution.

[0035] 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

[0036] Embodiment 2: Preparation of capsules of the compound of the present invention

[0037] Each raw material (unit: g) was weighed according to the following weight: 60 g each of 3'-(4-hydroxyphenyl)-propanol-benzoic acid ester and 4-hydroxycinnamic acid methyl ester.

[0038] Add 3'-(4-hydroxyphenyl)-propanol-benzoate and methyl 4-hydroxycinnamate to 100mL of ethanol, filter, add 1.8g of sodium starch glycolate, mix well, spray dry to make granules , into No. 1 capsules to obtain capsules.

Embodiment 3

[0039] Example 3: Preparation of Tablets of Compounds of the Invention

[0040] Each raw material (unit: g) was weighed according to the following weight: 60 g each of 3'-(4-hydroxyphenyl)-propanol-benzoic acid ester and 4-hydroxycinnamic acid methyl ester.

[0041] Add 3'-(4-hydroxyphenyl)-propanol-benzoate and methyl 4-hydroxycinnamate to 100mL of ethanol, filter, add 1.8g of sodium starch glycolate, mix well, spray dry to make granules , sent to the tablet machine for tableting.

Abstract

The invention relates to the technical field of pesticides and medicines, and particularly relate to an application of two compounds to preparation of a pesticide for killing nematode. The two compounds are safe and reliable, effectively prevents and controls the nematode disease agriculturally, can be medically used to repel nematode parasites, has no toxic or side effect on the human body, doesnot cause chemical dependency, is superior to the conventional pesticides and medicines, and can be widely used to the preparation of the pesticide for killing the nematode.

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)...
