Problems solved by technology

[0002] my country is a large agricultural country. The input of agricultural materials such as chemical fertilizers and pesticides has maintained the continuous and stable growth of my country's grain and agricultural product output. However, the long-term inefficient use of traditional chemical pesticides has also caused food safety and ecological environment problems.
It is understood that the amount of pesticides used in my country is as high as millions of tons per year, and chemical pesticides are easily lost into the soil and water sources through dripping, dust drifting, rain erosion, etc., and the utilization rate is only about 30%. The application of pesticides not only increases production costs, but also leads to serious environmental pollution and excessive pesticide residues, which has become a bottleneck restricting the sustainable development of agriculture in my country

Embodiment l

[0093] 1. At room temperature, according to the mass parts, 400 parts of main material A leaching solution, 200 parts of main material B leaching solution, 200 parts of main material C leaching solution, 100 parts of main material D leaching solution, nano-membrane 100 parts of destoned powder, mix and stir evenly, let stand in the storage tank for 24 hours, and stir once during the period.

[0094] 2. After stirring, filter through a 200-mesh filter to obtain a composite plant-derived nano-pesticide.

[0095] 3. Measuring, bottle-packing and storing the composite botanical nano-pesticides.

[0096] Preparation of major ingredient A extract comprises the following steps:

[0097] 1. Crush the deer vine to 100 mesh to obtain the deer vine powder residue.

[0098] 2. Add 60°C clear water with 10 times the weight of the deervine powder residue and 0.5% compound enzyme agent of the weight of the deervine powder residue, mix evenly, and soak at 60°C for 24 hours.

Embodiment 1

[0112] Example 1 was applied to a honey pomelo garden in Meizhou, Guangdong, spraying 5 times, spraying 1 time every 20 days. Use 200ml per mu of land each time, mix with 30kg of clean water and spray evenly on leaves, branches and small green fruits. The honey pomelo tree is growing well, the control of diseases and insect pests reaches 90%, the yield increases by 25%, and the proportion of first-grade fruit (commodity) reaches 90%.

Abstract

The invention discloses a composite plant-sourced nanosized pesticide and a preparation method thereof, and achieves the purpose of protecting the environment and reducing the agriculture production cost. The composite plant-sourced nanosized pesticide is prepared from the following raw materials: derris extract liquid, synedrella nodiflora extract liquid, melia azedarach extract liquid, rhododendron molle extract liquid and nano montmorillonite powder. The preparation method comprises the following steps: uniformly mixing the derris extract liquid, the synedrella nodiflora extract liquid, themelia azedarach extract liquid and the rhododendron molle extract liquid, adding the nano montmorillonite powder, uniformly stirring, standing in a storage tank, and filtering, thereby obtaining thecomposite plant-sourced nanosized pesticide. Compared with the prior art, the composite plant-sourced nanosized pesticide has the advantages that the water solubility and the dispersibility of poorlysoluble drugs are improved, the pollution to soil and a water source, which is caused by a harmful solvent and an additive, is avoided, the foliar deposition rate and the retention volume in the pesticide spraying process are improved, the pesticide loss is reduced, the duration is prolonged, the pesticide effect is slowly released, the pesticide applying dosage and times are reduced, and meanwhile, the agriculture production cost is reduced, and the composite plant-sourced nanosized pesticide can be applied to various crops.
