With the in-depth promotion of agricultural sustainable development and the concept of green and environmental protection, the greening and efficientization of pesticide preparations has become an important development direction of the agrochemical industry. In recent years, Nanocellulose , as a natural, efficient and renewable functional nanomaterial, has shown broad application potential in the field of pesticide preparations and has gradually become a hot topic of attention in the industry.
Nanocellulose is a nano-scale fiber material prepared by mechanical, chemical or enzymatic methods based on natural plant cellulose as raw materials. Nanocellulose has high specific surface area, high strength, good dispersion and biodegradability, and is a typical green sustainable material. At present, nanocellulose has been widely used in many fields such as food, papermaking, coatings, medicine, petrochemicals, etc., and has gradually expanded to agricultural fields such as pesticide preparations.
1. As a high-efficiency dispersion stabilizer
In pesticide suspension agents, microemulsions, wettable powders and other preparations, nanocellulose can be used as a natural dispersion stabilizer, which can form a three-dimensional network structure in the aqueous phase or the oil phase, effectively prevent the settlement, aggregation and stratification of the active ingredients, and significantly improve the stability and storage performance of pesticide preparations.
2. Improve the controlled release effect.
Nanocellulose has good drug-carrying ability. It can coat pesticide active ingredients through physical adsorption or chemical combination to delay the pesticide release rate, achieve the sustained and controlled release effects, reduce the loss of effective ingredients, and improve pesticide utilization rate.
3. Enhance adhesion and rainwater erosion resistance.
After spraying on the crop surface, nanocellulose can form a dense microscopic network membrane, improve the adhesion of the preparation on the leaves, reduce the probability of pesticide loss due to rainwater erosion, and prolong the biological activity time of pesticides.
4. Improve safety and environmental protection.
Nanocellulose is naturally sourced and biodegradable, which can effectively reduce the secondary pollution caused by traditional chemical additives to the environment, and meet the needs of green agriculture and sustainable development.
Green and natural, environmentally friendly : a wide range of sources, has little impact on the environment during preparation, and can naturally degrade.
Improve the performance of the formulation : significantly improve the dispersion, suspension, stability and adhesion of pesticide preparations.
Improve pesticide utilization rate and reduce usage : extend the effectiveness of pesticides, reduce pesticide usage and application frequency, and help save costs.
Flexible application and suitable for a variety of dosage forms : it can be widely used in different dosage forms such as pesticide suspension agents, emulsion oils, microcapsule suspension agents.
Against the backdrop of ' dual carbon ' goals and green agriculture, the application of nanocellulose in pesticide preparations is gradually moving from laboratory research to practical application. In the future, with the continuous maturity of nanocellulose preparation technology and the further reduction of costs, its potential in pesticide sustained release, green additives, etc. will be developed to a greater extent, and is expected to become an important technical support for promoting sustainable agricultural development and reducing pesticide environmental residues.
