Abamectin and Emamectin Benzoate
As an efficient broad-spectrum insecticide, abamectin is relatively safe to mammals and environmental compatibility. With more extensive use, pests’ resistance to abamectin has enhanced. Therefore, the development of the industry will turn to produce abamectin derivatives products such as ivermectin, emamectin, acetyl abamectin and milbemectin. The market will be expanded in fields such as insecticide miticide, livestock dual-use insect repellents and home health medication.
Since 1995, production of abamectin’s active compound has been increased at an annual rate of 50%, and the production capacity is also expanded yearly. In recent years, with the improvement of production technology year by year, sales price fall offsets rising costs associated with resistance increases, so the abamectin products maintain its advantage in the price performance ratio. Besides, since the low cost and high toxicity pesticides are gradually restricted to use, abamectin products will be widely used in developing countries.
Currently, production capacity of abamectin insecticide reaches 3,800 tons per year in China, with actual production about 2,400 tons per year in 2009. From 1995 to 2008, there is a 50% increase in demand. In 2009, with lighter pests and substantial expansion of production capacity and other reasons, supply and demand situation of abamectin is serious at first but then easy. Its total demand increased with an annual growth rate over 30%. The growth rate fell back. Among the demand, emamectin benzoate significantly stimulates the demand for abamectin concentrate.
From analysis above, experts believe that there will be a new round of substantial expansion with the price of abamectin active compound soared. By reason of expanded production scale and further improved technology, the cost of abamectin further declines. This helps to maintain a low price of abamectin active compound. It is estimated that Chinese advantage in the price performance ratio of abamectin can keep 2 to 4 years during which Chinese market will enter into a mature stage.
Emamectin benzoate is abamectin’s derivatives. Its active compound is moderately toxic, while its preparation is lowly toxic. Besides, it is not affected by the bad weather. Its activity to lepidopteran is higher 1 to 3 grades compared with abamectin. Abamectin’s active compound has highly toxic. Currently, abamectin preparation has been excessively used and led to exceeding residue. Since avermentin products are mainly made from emulsifiable concentrate and discharge much organic emission, they are not conductive to environmental safety. Relatively speaking, emamectin benzoate is characteristic of higher activity, fewer residue, lower toxicity and better security. In addition, it has advanced formulations which are beneficial for environmental protection.
From the global pesticide market, sales of bio-pesticides and transgenic pesticides only account for 10% of global pesticide sales. However, it accounts for less 5% in China, which shows that abamectin has a good market prospect in China. With farmer’s increasing awareness of properties of abamectin and its derivatives, it has become the most popular and highly competitive product in the bio-pesticide market. With abamectin and emamectin extensive use in rice, the last big market has been opened. It is estimated that future development will focus on replacing abamectin with emamectin.
