Polyvinylpyrrolidone (Esther-PVP K30)

1.      Seed Surface Treatment(Seed Coat)

PVP K30 can be used as a seed coating agent for the surface treatment of crops or other plant seeds. By forming a protective film, PVP K30 can improve seed physical properties (such as resistance to mechanical damage), enhance seed stress resistance (such as drought resistance, saline-alkali resistance), and may improve germination rate and seedling survival rate by regulating the seed germination microenvironment.

2.      Anti-Browning Agent In Plant Tissue Culture

PVP K30 was used as an anti-browning agent in plant tissue culture. For example, in the tissue culture test of Gala' leaves, the addition of 400 mg/L PVP K30 can effectively inhibit leaf Browning, especially the Browning rate of adult leaves is significantly reduced, thus improving the survival rate and differentiation potential of explants.

3.      Functional Additives For Agriculture-Related Preparations

Due to its dispersion, thickening and film-forming properties, the PVP K30 may be used in the following areas:

Pesticide Or Fertilizer Preparations: Acts as a dispersant or stabilizer to help distribute the active ingredient evenly and prolong its effect.

Water Treatment Membrane Material: In agricultural irrigation or hydroponics systems, PVP K30 can be used as a pore-causing agent for water treatment membranes to improve the separation performance of the membranes. there by optimizing water quality.

4.      Auxiliary Agent For Foliar Fertilizer And Plant Growth Regulator

Promotes Nutrient Absorption: The wettability of Tween can help trace elements in leaf fertilizer to penetrate plant leaves quickly and improve fertilizer utilization.

Stable Nutrient Solution: Span is used to emulsify oily components of foliar fertilizer to prevent delamination and ensure uniform spray.

5.      Other Agricultural Related Applications

Seeds Treatment: Span and Tween can be used as emulsifiers or wetting agents for seeds coating agents to help pesticides or nutrients adhere evenly to the surface of the seeds, improving germination rate and disease resistance.

Equipment Cleaning: Tween 80's low foaming and decontamination capability is suitable for cleaning pesticide spray equipment to reduce residue clogging. Water treatment: in irrigation systems, the dispersion of the pan prevents mineral deposits in pipes, while Tween helps dissolve organic impurities and optimizes water quality.

6.      Environmental And Safety Considerations

Biodegradability: Span and Tween based on natural fatty acid structure, some models are biodegradable reducing the risk of contamination to soil and water.

Low Toxicity: Non-ionic characteristics make it less irritating to plants and mammals, suitable for green agriculture needs.
