Embodiment 1

[0012] Embodiment 1: the preparation of pollution-free fungicide herbicide

[0013] The invention provides a nano-sustained-release suspension of neem bark plant source, which is characterized in that it is prepared from the following raw materials in parts by weight: 10-30 parts of neem bark, 10-20 parts of chrysanthemum chrysanthemum, 10-20 parts of water, nano-suspended Release carrier 30-35 parts;

[0014] The preparation method of described nano sustained-release carrier is:

[0015] (1) Mix silicon hydroxyapatite and kaolin according to the mass ratio of 30-40: 27-35, add to the mixed solution of 250 parts of dimethyl sulfoxide (DMSO) and 50 parts of methanol, at 55 ℃ Stir for 50 hours, filter, and 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 modified compound thing;

[0016] (2) Mix 1 part of the primary modified compound, 25 parts of potassium ...

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 chinaberry bark plant based nano carrier water suspending agent and a preparation method thereof. The invention is characterized in that the suspending agent is prepared from the following raw materials in parts by weight: 45-55 parts of chinaberry bark and the like. The suspending agent provided by the invention can be used for soil treatment after planting before seedling, and has the characteristics of farmland weed eradication and broad-spectrum sterilization. Compared with the prior art, the formulation provided by the invention has the characteristics of favorable weed eradication effect, high safety for environment and the like, and the weed can not easily generate drug resistance, thereby having wide application prospects.

Description

technical field [0001] The invention belongs to the technical field of pollution-free fertilizers, and in particular relates to a plant-derived pesticide composition of neem bark. 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 to people who eat the...
