2,4-D is the largest herbicide in the phenoxy acetic acids. 2,4-D can make the stems and leaves of weeds distort and swell through disturb the balance of hormones and destroy the metabolism of nucleic acid and protein; 2,4-D usually has two kinds of action modes: either growth stimulation or growth inhibition; the growth inhibition mode enable 2,4-D applied as a herbicide, while the growth stimulation mode enable 2,4-D applied as a PGR to improve the quality and yield.

Invention of 2,4-D is an important milestone in the agrochemical history. It first came to the market in 1945 and then rapidly applied in cereals, maize, soybean, rice and sugarcane as the first selective herbicide. The product has been used for 70 years with low cost, good efficacy for control of broad leaf weeds and rare report of resistance. Recently, 2,4-D has been used for the control of Glyphosate resistance weeds when Glyphosate-resistance getting severe. A significant opportunity for 2,4-D is the imminent introduction of the Enlist Weed Control System from Dow, which will incorporate both glyphosate and 2,4-D tolerance into crops. It is expected that the use of 2,4-D will be further expanded in future with the commercialization of Enlist technology.

2,4-D industry in China has been lagging behind in the world. The traditional manufacturing process is not competitive in oversea markets because of the low quality and high pollution etc. CAC Nantong had developed an clean 2,4-D production process with more than 10 years of continuous development; the clean process broke through the key problems of China 2,4-D including high pollution, effluent treatment, and low quality etc. The innovative technology was elected as the “12th 5 years science and technology supporting project”.


Below is the key advantages of CAC Nantong’s 2,4-D clean process:

1.     The first commercialized odorless 2,4-D product in the world, make the products more friendly to farmers;

2.     The innovative clean process avoided the pollution of waste gas and effluents;

3.     Creative crystalline, make the products no dust and better solubility, give better environment for formulation manufacturing;

4.     Largest capacity in the world, to ensure the stable and competitive supply;

5.     Participated in the FAO standards and Chinese industry standards to keep the healthy development of 2,4-D industry.



Chlorothalonil is one of the most important multi-site broad-spectrum protective fungicides in the world. Its mechanism is that chlorothalonil acts on the Glyceraldehyde-3-phosphate dehydrogenase (GAPDH) in fungal cells and combines with the protein containing cysteine in the enzyme, thereby destroying this enzyme activity and destroying the metabolism of fungal cells. Chlorothalonil is widely used in main kinds of crops to control plant diseases and has little risk of resistance. So far, there has been no report on Chlorothalonil resistance.


Since its launch in 1963, Chlorothalonil has been widely used as a major fungicide in the global market. In 2016, the global sales of Chlorothalonil amounted to $330 million, and the market demand increased steadily. Although new fungicides are launching into the market, the problem of resistance is also growing, and the more selective of single-site fungicides, the faster development of their resistance. Therefor the importance of multi-site protective fungicides is increasing and the future market demand for Chlorothalonil will maintain a stable growth.


CAC has established the following unique advantages through more than 20 years of continuous R&D and production technology innovation for Chlorothalonil.           

1.      Own CAC patented core catalyst and unique ammonia oxidation technology with self-production of intermediate products;    

2.      Has first –class production base with advanced automation level and high standard of EHS;            

3.      The world's largest Chlorothalonil production scale and the largest single-line capacity in the world.           

CAC’s technology advantage, high standard level and big scale of production will ensure the leading position of CAC in Chlorothalonil; so that CAC can continuously provide customers with more stable supply, more cost-effective and better quality products.



Azoxystrobin is the largest strobilurin fungicide in the world. Its mechanism is to inhibit mitochondrial respiration of pathogenic fungi and destroy energy synthesis of pathogenic fungi. Azoxystrobin work against pathogenic fungus by 3 ways of the protective, the curative and the eradication. It has broad spectrum of disease control and work well against almost all fungal diseases, such as powdery mildew, rust, glume blight, net blotch, downy mildew and rice blast etc.


Azoxystrobin was first reported at the Brighton Plant Protection Conference in 1992. It entered the market in 1997 and its global sales reached US$200 million in 1998 just one year after commercialized. The sales increased steadily year by year. By 2015, the global sales reached US$1.3 billion, which is the largest agro-fungicide in the world. It account for nearly 10% of the global Fungicides market. At present, Azoxystrobin has been registered in hundreds of countries to control more than 500 diseases on hundreds of different crops. Due to its broad-spectrum, high efficiency, its’ promoting the healthy growth of plants, and the continuous decline of farmer cost, the market demand for Azoxystrobin will have big potential to grow in the future.

CAC has become the largest manufacturer of Azoxystrobin in China through the continuous R&D and technological innovation of Azoxystrobin over the years, and has established the following unique advantages:           

1.      Own CAC patented unique Azoxystrobin production process which can support customers to develop high value market.           

2.      Have self-production for 2 core key intermediates which can ensure stable production and cost competitiveness.           

3.      Participate in the formulation of the national standard of Azoxystrobin; Initiate the application of Azoxystrobin FAO standard, and pass the evaluation in 2019.


All these will enable CAC’ Azoxystrobin product quality always to be in the leading position in the country and even in the world.
