example 1

[0007] Example 1: Clean the green bark of the fruit of the Chinese catalpa and the leaves of the Chinese catalpa, dry it, crush it, and sieve it with a 20-mesh sieve to obtain the raw material powder; weigh 50 kg of the powder, add 100 kg of clear water to it, and control the water temperature at 30°C Left and right, leaching for 20 hours; solid-liquid separation to obtain the filtrate, that is, the green bark and leaf insecticide of the fruit of Juglans catalpa. The solid slag at this time can be used again for leaching operations to avoid loss and waste of raw materials.

example 2

[0008] Example 2: Clean the green bark of the fruit of the Chinese catalpa and the leaves of the Chinese catalpa, dry it, crush it, and sieve it with a 20-mesh sieve to obtain the raw material powder; weigh 100 kg of the powder, inject 400 kg of water into it, and control the water temperature at 90°C The above, decocting for 2 hours; solid-liquid separation to obtain the filtrate, that is, the green bark and leaf insecticide of the fruit of the Chinese catalpa.

[0009] The insecticide has a good control effect on field and crop pests and weeds.

Abstract

Belonging to the technologies of pesticide preparation, the invention relates to a method for extracting a pesticide from juglans mandshurica fruit green peels and leaves. The method comprises: washing, air drying and crushing juglans mandshurica fruit green peels and leaves, sieving the crushed material through a sieve of 20 meshes, adding water into the sieved juglans mandshurica fruit green peel and leaf powder for immersion extraction or decoction extraction, then conducting solid-liquid separation, thus obtaining a juglans mandshurica fruit green peel and leaf pesticide. The method provided in the invention has the characteristics of simple extraction process, low production cost, high extraction efficiency, as well as good quality of the pesticide product, and can meet the use of industrial batch production.

Description

technical field [0001] The invention belongs to the insecticide preparation technology, and mainly relates to a method for extracting the insecticide from the green bark and leaves of the fruit of the Chinese catalpa. Background technique [0002] Walnut catalpa is a wild tree species in the cold region of northern my country, mainly distributed in the Greater and Lesser Khingan Mountains in the northern part of Heilongjiang Province. In recent years, scientific research has found that the green bark and leaves of Juglans fruit contain juglone, which has analgesic, antibacterial, anti-inflammatory and anti-tumor effects in medical treatment, and has a long acting time, no addiction and non-toxicity Side effects; at the same time, in agricultural production, scientists have discovered that juglone also has the effect of killing crop pests, so it can be used as an agricultural pesticide. In addition, after the crops are used with insecticides containing juglone, the crop seed...
