At present, China's new pesticide formulation of water-based formulations and dispersible granules development priorities, water-based formulations with water instead of organic solvents as dispersion medium, compared to the traditional forms such as EC and WP help conserve resources, reduce costs, advantages of protecting the environment, and thus has broad prospects for development. Pesticide suspensions is the modern pesticides very important pesticide formulations, has good biological activity, but due to the ingredients of pesticides suspension system is complex, often preparations by poor physical stability, such as hierarchical, analysis of water, flocculation, etc. problem. Based on this, the author of this article in June 2007 to May 2009, a new insecticide indoxacarb objects, research of the indoxacarb its indoxacarb - chlorpyrifos mixed suspension hanging milk system and thixotropic, discover indoxacarb 10% SC and indoxacarb - chlorpyrifos 25% suspension emulsion methods of analysis, evaluation of indoxacarb - chlorpyrifos 25% of the combined effects of the suspension emulsion and made some stage of the research results. According to the research content, the text is divided into six parts. The first part is a literature review. Briefly comment on the the pesticide suspension / suspension emulsion system overview of existing common key technical problems, introduced by indoxacarb and chlorpyrifos physical and chemical properties, the research background and significance of the text. The second part of the study indoxacarb 10% SC System and Its Performance in conflict with the post. The flow point method and orthogonal test method for screening the type and amount of surfactant the indoxacarb suspension system when wetting and dispersing agent D-425, Nongru 1602, NS-500LQ and viscosity modifiers XG dosage 3%, 1%, 1% and 0.10%, the various quality indexes of the of indoxacarb suspension system basically meet the requirements; On this basis, continue to study the bentonite, acidic bentonite, alkaline bentonite, diatomaceous earth, bump rod soil, and magnesium aluminum silicate minerals in suspension form possibilities and the advantages and disadvantages of the thixotropic system, and found that a 1% to 3% and 3% bentonite and magnesium aluminum silicate is added in the system, with a suspension of a thixotropic system has a major impact on thixotropic thixotropic system and reusable; screening the the different antifreeze suspension antifreeze effect, anti-freeze on the system have a certain impact dispersion; explore indoxacarb Formulations of 10% of suspending agent, identified by two Shipping recipe: ① indoxacarb 10% D-425 3%, the 1602 Nongru 1%, the ns-500LQ 1-%, 1 to 3% of bentonite, glycol % xanthan gum the XG 0.2% and the balance water to cover; ② indoxacarb 10% D-425 3%, the 1602 Nongru 1%,. NS-500LQ1%, 3% magnesium aluminum silicate, ethylene glycol 3% , xanthan gum XG 0.1% and the balance water to make. The third part of indoxacarb - chlorpyrifos 25% suspension system of milk. Chlorpyrifos water emulsion formulation optimization processing system had good stability chlorpyrifos 30% emulsion in water and mixed with indoxacarb suspensions, the proportion of different mixed with the mixing process, found that when indoxacarb: chlorpyrifos (m: m) = 1:4 to 1:5 when, indoxacarb placed The chlorpyrifos-water emulsion dispersed phase sanding 3h, good stability can be obtained indoxacarb - Chlorpyrifos 25% suspension emulsion, Formulations composed of indoxacarb 4% Chlorpyrifos 21% D-425 3% Nongru 1602 5%, the ns-500LQ 1-%, PNP 10% cosolvent 1%, 5% ethylene glycol, magnesium 3% of aluminum, the xanthan gum XG0.1% CMC 0.1%, the remainder water. The fourth part of a single dose of indoxacarb and indoxacarb - chlorpyrifos mixture detection method. Through the exploration of the chromatographic conditions, indoxacarb 10% SC and indoxacarb - chlorpyrifos 25% suspension emulsion HPLC analysis method, the established method is accurate, rapid and reproducible, high sensitivity, suitable for product quality testing and analysis. The fifth part of the evaluation of indoxacarb - chlorpyrifos mixture combined effects of the diamondback moth. Using the bioassay measured indoxacarb, chlorpyrifos and its mixed combination of Plutella xylostella and found indoxacarb and chlorpyrifos mixed diamondback moth has obvious synergies, the co-toxicity coefficient of 128.24. The sixth part of the conclusions and recommendations. That part of a summary of the full text of findings of the study of the characteristics of its innovation, to be further studied in the future.
