[0046] Two, the preparation method of Liwu powder composite granule

Embodiment 10

[0047] Example 10, a preparation method of Ligularia fruticosa powder composite granule (formulation of Example 5) comprises the following steps:

[0048] (1) Preparation method of effective active ingredients

[0049] Ligularia chinensis powder below 250 microns: In early August, pick the leaves of Ligularia spp. and quickly dry them in the shade at a temperature of 30°C. The dry leaves are ultrafinely pulverized for 3 times, and passed through an 80-mesh sieve to obtain ultrafine powder of Ligularia fructus leaves with a particle size of less than 250 microns.

[0050] Coptis chinensis powder below 250 microns: In November, 5-year-old Coptidis rhizome roots were harvested and dried quickly at 35°C. The dry root of Coptidis rhizome is ultrafinely pulverized five times, and passed through an 80-mesh sieve to obtain superfine powder of Coptidis rhizome root with a particle size of less than 250 microns.

Embodiment 11

[0054] Example 11, a compound granule of Ligularia chinense powder (formulation in Example 1), the preparation method comprises the following steps:

[0055] (1) Preparation method of effective active ingredients

[0056]Ligularia chinensis powder below 250 microns: in July, pick the leaves of Ligularia spp., and quickly dry them in the shade at a temperature of 25°C. The dry leaves are ultrafinely pulverized for 3 times, and passed through a 60-mesh sieve to obtain the ultrafine powder of Ligularia cloverleaf leaves with a particle size of less than 250 microns.

[0057] Coptis chinensis powder below 250 microns: In October, 6-year-old Coptidis rhizome roots are harvested and dried quickly at a temperature of 30°C. The dry root of Coptis rhizome is ultrafinely pulverized four times, and passed through a 60-mesh sieve to obtain ultrafine powder of Coptidis rhizome root with a particle size of less than 250 microns.

Abstract

The invention provides ligularia virgaurea powder composite granules as well as a preparation method and an application technology thereof. The ligularia virgaurea powder composite granule is prepared from 70%-85% of effective active ingredients and 15%-30% of auxiliaries. The main effective active ingredients are micronized by using a superfine powder technology, and then are prepared into granules by using a modern granulation technology. The insecticidal composition is mainly used for preventing and controlling coleoptera, lepidoptera, orthoptera and diptera underground pests such as grubs, wireworms, cutworm mole crickets and root maggots, and also preventing plant diseases caused by pathogenic bacteria such as pathogenic fusarium, phytophthora, rhizoctonia solani and lauraceae. The method is suitable for a modern large-scale mechanical planting production mode; the pesticide is efficient, multiple in effect and long in lasting period, diseases and insect pests are prevented, and the average prevention and control effect on target diseases and insect pests is 60%-85%; soil is improved, and continuous cropping obstacles can be prevented and controlled; the application target is clear and the control spectrum is wide.

Description

technical field [0001] The invention belongs to the field of biopesticides, and specifically relates to an insecticidal and antibacterial composite granule whose main active ingredients are Liwu powder and Coptis chinensis powder, as well as its preparation method and application technology. Background technique [0002] Since environmental factors such as geological features and climatic conditions have a great impact on the nutrition, quality and yield of agricultural products, agricultural products such as vegetables, grains, fruits, and Chinese medicinal materials all pay attention to regional characteristics. In order to maintain stable production and economic benefits, it is difficult to rationally rotate crops and stubble, coupled with the extensive use of chemical fertilizers and pesticides, the soil ecological environment is deteriorating, and the incidence of underground diseases and insect pests is becoming more and more serious. Fusarium wilt, root rot, blight, b...
