EPA Proposed Conditional Registration of Nanosilver Pesticide
2010-8-30
EPA is proposing to conditionally register a pesticide product containing nanosilver as a new active ingredient for a period of 4 years. The antimicrobial pesticide product, HeiQ AGS-20, is a silver-based product that is proposed for use as a preservative for textiles. Under its new policy concerning public involvement in registrations, EPA is providing a 30-day opportunity for public comments on the proposed registration. Public comments will be accepted until September 11, 2010.
As a condition of registration, EPA is proposing to require additional product chemistry, toxicology, exposure, and environmental data. The Agency will evaluate these data as they are submitted during the period of the conditional registration to confirm the product will not cause unreasonable adverse effects to human health and the environment.
The data requirements are based in large part on a November 2009, independent consultation EPA held with the FIFRA Scientific Advisory Panel(SAP).In its final report,(http://www.epa.gov/scipoly/sap/meetings/2009/november/110309ameetingminutes.pdf), the SAP addressed a number of questions associated with assessing the hazard of and exposure to nanosilver and other nanoscale metal-based pesticides. EPA is closely following the scientific recommendation from the SAP.

A New Generation of Pesticides Nitenpyram
2010-8-30
Nitenpyram is a new generation of insecticide used in agriculture and veterinary medicine to kill insect external parasites of livestock and pets. It has good performance, with reliable technology, raw materials and good prospects, but until the end of 2009 domestic production capacity is only 1,000 tons/year, which still unable to meet domestic demand, the status of domestic pesticide production deserves more attention.
We should speed up Nitenpyram similar products research and development, such as Clothianidin Lin, Thiamethoxam, Thiophene insects amine, Furosemide insects amine, chlorine and other insects morpholine.
According to the current domestic production and market demand, there are some recommendations for new suppliers: First of all, constantly promote Chinese pesticide production and application upgrades; Secondly, speed up high-level nitenpyram development in order to meet domestic market demand, on the other hand, develop the downstream of neonicotinoid pesticides series; Thirdly, synthetic route optimization, focus on 2 - chloro -5 - chloromethyl pyridine and nitro oxide (or nitro-vinyl) materials such as route selection, to further reduce production costs of raw materials; Fourth, to speed up nitenpyram similar products research and development, such as clothianidin, thiamethoxam, thiophene insects amine, furosemide insects amine, chlorine and other insects morpholine. Finally, to meet the needs of the domestic market, while strengthening the international market expansion.

The Concerns For The Future of Nicosulfuron
2010-8-27
Nicosulfuron is the world's dominant sulfonylurea herbicides, mainly for corn, is a perennial grass weeds effects of herbicides. In early 2007 the patent expired in China, 2007 -2008 International crude oil prices surge, the huge market demand for bio-ethanol triggered a global wave of corn, nicosulfuron pesticide companies competing to become one of the best. Rapid expansion of production capacity, excess capacity situation is gradually showing the same time, continued low prices, export growth slowed down, cautiously optimistic about the future market demand, competition and other factors determine the emerging Nicosulfuron future expansion should not be blind. Nicosulfuron herbicides as a corn field, no doubt about its performance and effectiveness. With the promotion of in-depth research and application, good prospects for the domestic market demand. According to the State Grain Bureau information shows that in 2009 corn acreage increased by 2% in 2010 to continue growing corn planting area will stabilize at about 30 million hectares. The steady growth of planted area, making Nicosulfuron good prospects for the domestic market demand. Despite the excellent performance prospect, there are some uncertainties. Firstly, major movement of feed corn consumption and bio-ethanol, due to the uncertainty of world economic recovery, there are many uncertainties in time. Secondly, the development of coal chemical industry, indicating that ethanol fuel will be officially recognized, is bound to impact on bio-ethanol market. Thirdly, is the sulfonylurea herbicide usage and as time requirements more stringent,to some extent, affected Nicosulfuron market. Lastly, emerging competitors due to safety and weed control efficiency was highly praised by the market, while new sulfonylurea herbicide being developed and applied, such as a sulfonamide ethyl. Therefore, the uncertainties of the future prospects, nicosulfuron cautiously optimistic about the future of the market should be. From：http://www.chinapesticide.gov.cn/doc10/10082504.html
