Suspension concentrate (SC)
Microcapsule suspension (CS)
Microcapsule
Microcapsule suspension is a kind of microcapsule with semi permeable membrane formed by wrapping pesticide active substance (core) with polymer material as the wall or membrane through chemical, physical or physicochemical methods, and they are stably dispersed and suspended in water as a continuous phase in a certain concentration, which is called microcapsule suspension.
Suspension concentrate (SC)
Suspension
In recent years, with the deepening understanding of the hazards of emulsifiable pesticides, water-based formulations have been highly valued. According to the statistics of the world pesticide industry association, the proportion of EC in the world's pesticide preparations is very large, and the organic solvent in the environment is more than 1 million tons per year. In one hand, these non-pesticide active substances increase the cost of pesticide preparation, which consumes about billions of dollars every year in the world; on the other hand, a large number of organic solvents cause great damage to the environment. China is the second largest pesticide producer in the world, producing 900000~1 million tons of pesticide preparations every year. China's water-based formulations account for a small proportion of the total preparations. Compared with other major producers of pesticides, the structure of pesticide formulations in China is facing severe challenges, and the demand for new water-based formulations is also more urgent. In this context, water-based preparations, such as suspensions, microemulsions, water emulsions, and water-based agents, are widely concerned, and their development technology has become a hot spot. Related basic theoretical research, such as surfactant technology, nanoparticle technology, laser particle size and streaming potential detection technology, grinding technology and fluid mechanics, have also gradually extended to the field of pesticide, providing a necessary means and theoretical basis for further research on Suspension Concentration.
Dry flowable(DF)
Dry
Dry Flowable (referred to as DF) is a solid particulate product obtained directly from pesticide by wet grinding and then spray dried and granulated to remove moisture. China's pesticide registration department uses the name of WG (water dispersible granule) instead of DF to register WG and DF. According to the different production processes, WG is divided into dry process and wet process. DF is water dispersible granule produced by wet process. Due to the process, some DW is registered as water dispersing granule, while some DW is registered as dry suspending agent, which puzzles the users. In fact, there are obvious differences between dry WG and wet WG (i.e. DF) in appearance, and their water entry performance is also different, so it is not difficult to distinguish them.
Microcapsule Suspension- Suspension Concentration
Microcapsule
Microcapsule suspension is a kind of compound preparation, which is to compound microcapsule suspension and suspension, so that the product can meet the requirements of quick effect and extend the period of validity. It is a new formulation with both quick effect and effectiveness, and can expand the prevention and control objects, with a broad market prospect.
Dispersible Oil suspension (OD)
Dispersible
An insoluble pesticide solid active component in non-aqueous medium (mainly including oil-based medium or solvent medium), which is processed into fine particles and suspended in non-aqueous medium by the action of surfactants and additives to form highly dispersed and stable suspension liquid preparation, called oil suspension agent (of), oil suspension agent used for water dilution is called dispersible oil suspension agent, code is OD Oil suspension agent can increase the adhesion of pesticide on plant leaves and reduce the surface tension, so as to make the efficacy play better.
Seed Treatment
Seed
Seed Treatment agents play an obvious role and advantage in reducing and enhancing pesticide efficiency and preventing diseases and pests in crop seedlings and even the whole life cycle. Seed Treatment agents play an increasingly important role in agricultural production. Pilarquim has already launched two kinds of Seed Treatment agents, Miao De Yi and seed guard, which are loved and sought after by many growers. In 2020, Pilarquim will introduce three new Seed Treatment agents, Miao Wanjin, Miao Jianqiang and Miao Mei Qi. In addition to continuing to walk along the line of disease and insect pests, microcapsule technology will also be applied to Seed Treatment agent, so that Seed Treatment agent can play a longer and better efficacy.

According to the statistics of the world pesticide industry association, the proportion of EC in the world's pesticide preparations is very large, and the organic solvent in the environment is more than 1 million tons per year. In one hand, these non-pesticide active substances increase the cost of pesticide preparation, which consumes about billions of dollars every year in the world; on the other hand, a large number of organic solvents cause great damage to the environment. China is the second largest pesticide producer in the world, producing 900000~1 million tons of pesticide preparations every year.

Pilarquim's original "three essence process" and "three essence guarantee" have raised the production process and quality level of China's Suspension Concentration to a new level. In cooperation with foreign preparation suppliers, Pilarquim has also made many breakthroughs in the research of additives. Make the quality indicators of Pilarquim Suspension Concentration catch up with imported products, which has been praised by users.

1.     Overview of Suspension Concentration

Suspension Concentration, also known as water Suspension Concentration, colloidal suspension and concentrated Suspension Concentration, is a kind of important dosage form which represents the development direction of modern pesticide preparation technology. The basic principle is to disperse insoluble or water-insoluble raw materials into water under the action of surfactants and other auxiliaries and form a uniform and stable coarse suspension system. Suspensions are mainly composed of pesticides, wetting agents, dispersants, thickeners, antifreeze, pH adjustment agents, defoamer and water. Since the dispersing medium is water, the Suspension Concentration has the characteristics of low cost, production, storage and transportation and use safety, and can be mixed with water in any proportion, and is not affected by water quality and water temperature and is convenient to use. Compared with the pesticide formulation with organic solvent as the medium, it has the advantages of less environmental impact and less damage. In recent years, the development of microcapsule suspension and water-based suspension seed coating agent, although the names are different, but from the perspective of its dispersion principle, they also belong to the category of suspension agent, except that the former dispersion phase is microcapsule, and the latter has the function of forming membrane on the seed surface due to the introduction of film-forming agent on the basis of suspension agent.

2.     Development status of Suspension Concentration

Suspension agent is a new type of pesticide formulation which has a short history of development and is in constant improvement. The emergence of this new dosage form provides a new opportunity for the production and application of solid pesticides which are difficult to dissolve in water and organic solvents.

The developed countries have developed the Suspension Concentration earlier and popularized faster. Since the development of suspension concentrate in China in 1970s, great progress has been made in formulation research, processing technology and variety and quantity of preparations. In recent years, the development of specific suspensions is very fast, such as the emergence of a number of new compound suspending seed coating agents, and the registration of dry suspensions, microcapsule suspensions and Suspension Concentrations has increased year by year.

      

3.   Expectation

As people pay more and more attention to the living environment, it has become a hot topic in the field of pharmaceutics to seek to reduce the risk of pesticides and their use through the innovation of preparation technology. The uneven distribution of pesticides is caused by the inappropriate use of technology and pesticide formulations. In the future comprehensive strategies for insecticide resistance, pesticide formulations and pesticide use technologies must be used as necessary components in drug resistance management research. Technological development factors are the most direct influence factors of promoting pesticide pollution-free. In recent years, suspension agent, seed coating agent, microencapsulation agent, microemulsion agent, water dispersing agent and other technologies are effective ways to make pesticide pollution-free based on modern preparation processing technology. Suspension Concentrations conform to the trend of pollution-free pesticides in reducing the amount of organic solvents, using and storing safely and conveniently, maintaining a long period of time, and producing no "three wastes"(waste of water, gas and rests) in production. Starting from the above significance, the water-based preparation represented by Suspension Concentration will become one of the important means to solve the problem of pesticide pollution.
