Embodiment 1

[0013] Embodiment 1: the preparation of pollution-free fungicide herbicide

[0014] The present invention provides a plant-derived nanometer slow-release pesticide composition of the fruit of the plant, which is characterized in that it is prepared from the following raw materials in parts by weight: 40-50 parts of the fruit, 10-20 parts of Eupatorium adenophorum, 10-20 parts of water, 20-25 parts of nano slow-release carrier;

[0015] The preparation method of described nano sustained-release carrier is:

[0016] (1) Mix silicon hydroxyapatite and attapulgite according to the mass ratio of 35-45: 10-15, add to the mixed solution of 230 parts of dimethyl sulfoxide (DMSO) and 50 parts of methanol, at 65 Stir at 60°C for 60 hours, filter, wash 3 times with hot ethanol at 60°C to remove excess dimethyl sulfoxide (DMSO), put it in a vacuum drying oven, dry at 60°C for 24 hours, grind and sieve to obtain a primary modification Complex;

[0017] (2) Mix 1 part of primary modif...

Embodiment 2

[0020] Embodiment 2: the test area is located in the potato test area of ​​the farm, and the potatoes are made before, and the soil type is black soil, the soil organic matter content is 5.3%, and the pH value is 6.6; Spring fertilization; 175kg of phosphoric acid, 160kg of urea, and 125kg of potassium sulfate were applied per hectare.

[0021] There are 3 treatments in each test, 4 repetitions, each plot area is 10m2, and the test design is carried out according to a completely random design, wherein A: clear water blank control; B: compound carbendazim 800 times dilution positive control; C: this The 300-fold dilution of the botanical pesticide of the invention is used for seed dressing.

[0022] Survey content and data processing: 30 samples were randomly selected in each plot, investigated before the application of the drug and 30 days after sowing, recorded the number of diseased plants, and observed the emergence rate.

[0023] The test results show that the seedling em...

Abstract

The invention relates to a semen momordicae plant source nanometer slow-release pesticide composite and a preparation method thereof. The semen momordicae plant source nanometer slow-release pesticide composite disclosed by the invention can be used for soil treatment after sowing before seedlings emerge, prevents and controls farmland weeds and has a broad-spectrum bactericidal characteristic. Compared with the prior art, the composite has the characteristics of good weeding effect, safety to the environment, difficulty in weed drug resistance generation, wide application prospect, and the like.

Description

technical field [0001] The invention belongs to the technical field of pollution-free fertilizers, and in particular relates to a plant-derived nano slow-release pesticide composition of wood beetle. Background technique [0002] Plants will encounter various diseases and insect pests during their growth in nature, especially fungal diseases. There are many types and serious diseases. For example, gold disease, red gold disease, and black gold disease are common and difficult to control on many crops. Diseases have brought huge losses to agricultural production, and mainly occur in the tender seedlings, buds, shoots and other parts of crops. When severe, the leaves withered, curled, turned brown, and died. At present, a large number of chemical means are used for prevention and control. The main agents used for the prevention and treatment of powdery mildew in China are methyl. Harmful, and there are residues in a large amount, which are difficult to remove and cause harm t...
