Avermectin, a groundbreaking bio-pesticide, has emerged as a pivotal innovation in agricultural science, offering a low-toxicity and low-residue alternative to traditional chemical pesticides. This article delves into the development of avermectin, its applications, and the market dynamics that have shaped its journey from discovery to becoming a cornerstone in sustainable farming practices.
Avermectin is a series of 16-membered macrolide compounds, known for their potent insecticidal, acaricidal, and nematicidal properties. These compounds are derived from the fermentation of the soil bacterium Streptomyces avermitilis. Among the avermectins, abamectin stands out as a particularly effective antibiotic with a unique structure, suitable for both agricultural and veterinary applications.
The demand for bio-pesticides like avermectin has surged with the global push towards green food and sustainable agriculture. According to a report by MarketsandMarkets, the global biopesticides market size is projected to grow from USD 4.3 billion in 2020 to USD 8.5 billion by 2025, at a Compound Annual Growth Rate (CAGR) of 14.7% during the forecast period. This growth is driven by the increasing preference for organic products and integrated pest management practices.
The bio-pesticide market has seen significant growth in various regions. In 2004, Europe's bio-pesticide sales jumped from $100 million in 1997 to $169 million, with its usage accounting for 20% of the global market. North America led the market with a 44% share, followed by Asia (13%), Oceania (11%), Latin America and the Caribbean (9%), and Africa (3%). This trend indicates a shift towards bio-pesticides, with avermectin at the forefront of this movement.
Abamectin suppliers have anticipated that the 21st century will be dominated by biological pesticides, with abamectin being a highly sought-after product in the competitive bio-pesticide market.
The original abamectin drug appears as white or yellowish crystals. It has a low vapor pressure (<200nPa) and a melting point ranging from 150 to 155°C. Its solubility varies across different solvents: 7.8 µg/L in water at 21°C, 100 g/L in acetone, 350 g/L in toluene, 70 g/L in isopropanol, and 25 g/L in chloroform. Abamectin is stable at room temperature and does not decompose readily, even in solutions with pH levels between 5 and 9 at 25°C.
China began producing avermectin in 1995, with an initial export price of around 30,000 RMB per kilogram. Despite fluctuations in the market, the price remained profitable for manufacturers until a sharp decline in 2001, with rates dropping by 30% and reaching as low as 1,000-1,200 RMB in 2002. However, the discontinuation of production in the United States and the widespread use of abamectin in various crops led to a significant increase in demand. By the first half of 2004, the price had risen from 900 RMB/kg to 2,400 RMB/kg.
The European Union's pesticide ban, which came into effect on December 31, 2003, prohibited the sale of 320 types of pesticides, including insecticides, fungicides, and herbicides. This ban also affected imports of agricultural products containing chemical residue, leading to a shortage of avermectin and contributing to the price increase.
In 2004, avermectin experienced a surge in popularity, but the market faced challenges due to a vicious cycle of production and sales imbalances. While U.S. companies reported fermentation unit yields of about 8,000-10,000 µg/mL, Chinese manufacturers typically achieved 3,000-4,000 µg/mL. However, Chinese scientists have made significant strides in improving yields through advanced breeding methods, process optimization, and unique mutagenic measures. These efforts have resulted in fermentation titers reaching 8,400 µg/mL and stabilizing above 8,100 µg/mL.
Avermectin's journey from a novel antibiotic to a leading bio-pesticide reflects the agricultural industry's shift towards more sustainable and environmentally friendly practices. As the largest producer and exporter of avermectin, China plays a crucial role in meeting the global demand for this bio-pesticide, which continues to grow as the world embraces green agriculture.

Exploring the Potentials of Nano-Aluminum Powder
Nano-aluminum powder, a material with remarkable properties due to its minuscule particle size, is revolutionizing various industries with its high reactivity and large specific surface area. Unlike its bulk counterpart, nano-aluminum powder begins to oxidize at a lower temperature of 550°C, compared to the 950°C oxidation point of ordinary aluminum. This lower ignition energy and full combustion without apparent cohesion make it a superior choice for applications requiring high energy and efficiency. The unique characteristics of nano-aluminum powder, such as faster burning rates and greater heat release, are largely influenced by its synthesis method, which determines its particle size, surface area, and shape.
