Application cases of nanocellulose in pesticides

Nanocellulose (Nanocellulose) has gradually become a hot topic in the field of pesticides due to its unique physical and chemical properties, such as high specific surface area, excellent mechanical properties and biodegradability. The following are some practical applications of nanocellulose in pesticides:

1. Pesticide carrier and controlled release system

• Case: The lasting pesticide release nanocellulose
in vineyards can be used as a carrier or controlled release material for pesticides, helping to extend the time of pesticides acting on crops and reducing the amount of pesticides. For example, in vineyards, nanocellulose is used to wrap insecticides and form nanoparticles, which provide long-term pest control effects by slowly releasing drugs, while reducing volatility and loss of pesticides.

• Case: Nanocellulose-polymer composite carrier
By combining nanocellulose with biodegradable polymers, pesticide particles with a lasting sustained release effect can be prepared. This application has been used in soybean fields to control pests. Experimental results show that nanocellulose carriers can effectively control drug release, extend the time of pesticides, and reduce the frequency of pesticide use.

2. Nanocellulose-anti-bacterial composite material

• Case:
Nanocellulose in plant disease prevention and control can be combined with natural antibacterial agents or bactericides to prepare biocompatible and environmentally friendly antibacterial pesticides. For example, compounding nanocellulose with silver nanoparticles or plant extracts can have a lasting inhibitory effect on plant pathogens, especially in greenhouse vegetable planting, reducing the occurrence of diseases.

3. Pesticide preparation stabilizer

• Case: Nanocellulose stabilized emulsion Pesticide
In pesticide emulsion preparations, nanocellulose can be used as an emulsifier and stabilizer to prevent the emulsion from layering or precipitation. For example, in certain pesticide emulsions used in cotton fields, the addition of nanocellulose can improve the stability and durability of the formulation.

4. Green packaging materials

• Case: Degradable pesticide packaging
Nanocellulose is also used in degradable pesticide packaging. Traditional plastic packaging can cause pollution to the environment, while nanocellulose packaging can naturally degrade in the soil, reducing the negative impact of pesticide packaging waste on the environment. For example, in some small orchards or tea gardens, pesticide products packaged with nanocellulose have been accepted and promoted by farmers.

5. Synergists and adsorbents

• Case: Improve pesticide absorption efficiency
Nanocellulose can be combined with certain organic pesticides to increase its adsorption capacity in the foliar surfaces of plants or soil, thereby improving the efficacy of medicine. For example, the application of nanocellulose in glyphosate herbicides allows herbicides to better adsorb on the weed surface, thereby improving the herbicide effect.

6. Environmentally friendly soil improvers

• Case: Nanocellulose and pesticide composite soil improvement agent
In the field of soil improvement, nanocellulose can be combined with pesticides to make environmentally friendly composite materials, which can not only release pesticides, but also improve soil structure and maintain soil moisture and nutrition. Effectively reduce environmental pollution.

These cases show that nanocellulose can not only improve the efficiency of pesticide use, but also reduce the impact on the environment and make agricultural production more sustainable.
