Third, due to the chemical properties of the active ingredients, some excellent surfactants often react chemically with the active ingredients and affect the stability, so they cannot be added
[0007] 2. Poor permeability
The quality of penetration performance mainly depends on the surfactant, which is also subject to the content and chemical properties of the active ingredients. Many excellent surfactants are either insufficient or cannot be added, resulting in poor permeability
[0008] 3. Poor dispersion
However, because surfactants are mostly liquid or paste, it is difficult to process into solid preparations, which limits their application in pesticide or fertilizer solid preparations
[0010] Agricultural effervescent granules, that is, effervescent granules used in pesticide preparations or fertilizers to play an auxiliary role, no related products and reports

Abstract
The invention belongs to agricultural effervescent granules, and in particular relates to an effervescent granule applied to a pesticide preparation or a fertilizer, and a preparation method and application thereof. The agricultural effervescent granule comprises an acid source, a carbonate source and a surfactant. The optimized proposal of the invention is that the agricultural effervescent granule comprises 1 to 40 percent, preferably 2 to 30 percent of the surfactant in percentage by weight. The preparation method comprises the steps of weighing, mixing, crushing and granulating a formulation material to obtain the agricultural effervescent granule. The agricultural effervescent granule is mixed with the pesticide preparation and the fertilizer in use, and the dosage of the agricultural effervescent granule is 0.1 to 50 percent, preferably 0.5 to 40 percent in percentage by weight. A liquid medicine or a liquid fertilizer prepared by adding the agricultural effervescent granule has good wetting property, permeability and ductility, improves the utilization rate of effective components, reduces wastes and environmental pollution, and has obvious advantages of performance, cost, and environmental protection, and has extensive market application prospect.
Description
technical field [0001] The invention belongs to agricultural effervescent granules, and relates to an effervescent granule used for pesticide preparations or fertilizers, a preparation method and application thereof. Background technique [0002] The object of the present invention is to provide an agricultural effervescent granule with high efficiency, rapid dissolution (dispersion), and high stability. Another object of the present invention is to provide the preparation method and application of the above-mentioned agricultural effervescent granules. [0003] In the field of agriculture, pesticide formulations and fertilizers must meet a wide range of practical constraints. In addition to providing excellent properties such as insecticide, fungicide, weed control, regulation of plant growth, and supplementation of plant nutrients, they also need to meet many physical constraints that exceed these basic requirements. For example, the liquid medicine or fertilizer should ...
