China Pesticide Registration: Assessment of Risk to Aquatic Ecosystems
Pesticides are wildly used in agricultural production in China. The use of pesticides affects the environment significantly. Pesticides are introduced to the aquatic ecosystem in a variety of ways such as, leaching, evaporation and precipitation cycles, surface runoff etc. Chinese manufacturers produce a large amount of pesticides every year. Technical material production accounts for about 60% of global production capacity. This article will briefly introduce assessment of risk to aquatic ecosystems in China. Pesticide registration in China is based on tiered assessment whereby increased production volume incurs increased regulatory compliance requirements including the evaluation of pesticide impact to aquatic ecosystems. If primary evaluation is unacceptable, senior assessment is necessary. Environmental risk assessment consists of: Exposure assessment (predicted environmental concentration, PEC) Effect assessment (predicted no effect concentration, PNEC) Risk characterization (risk quotient, RQ). Exposure Assessment Exposure assessment is made up of primary exposure assessment and senior exposure assessment. For primary exposure assessment, a model is used to predict the surface water exposure level in which worst case scenarios are chosen for model parameters. Generally, the PEC is the maximal predicted environmental concentration, or the weighted predicted environmental concentration. For senior exposure assessment, modified parameters or field test data are often used in the exposure model, to find parameters similar to the actual situation. Actual monitoring data of common pesticides is also used as the exposure level. When using a model to analyze the exposure concentration, the areas of use, sites of application and methods of application should be considered to obtain the final PEC. During the exposure analysis, we need to find the appropriate endpoint, including soil adsorption coefficient, hydrolysis half-life, photolysis hal

11 New Active Ingredients to be Fully Approved in China
On 25 Aug 2016, China MoA released the meeting-minutes of the 19th session of the 8 National Expert Committee of Pesticide Registration, which was held on 26 Jul in Beijing. A total of 43 pesticides using 21 new active ingredients were reviewed for full registration.  20 pesticides using 11 new active ingredients were approved, of which 3 were submitted by MNCs: halauxifen-methyl herbicide by Dow Agroscience, fluoxastrobin fungicide and amicarbazone herbicide by Arysta.

Overview of Chinese Pesticide Market in 2015
A double digit decrease in exportation figures and a muted performance from China’s domestic market have reduced the profits of Chinese agrochemical producers; The full chain agronomic services offered by multinationals and domestic distributors have forced the traditional middleman out of the supply chain equation; Rising costs of compliance with China’s EHS regulations has transmitted to the agrochemical industry; Domestic products saw reduced or flat prices while imported products achieved 10 to 20 percentage growth; In 2015, China produced 1.33 million tons of pesticide active ingredients, down from 1.49 tons in 2014. Exportation fell by more than 10% in both volume and value terms. Influenced by complex factors including weather, regulatory policies and changing distribution channels, the domestic usage was slightly lower than expectation at 0.3 million tons, causing Chinese producers to feel the pinch of higher fuel and labor costs. Production and International Trade The largest percentage reduction occurred in herbicide and insecticide categories, decreasing the total production by about 11.7% compared to 2014, representing a 4-year low.

117 Soybean Pesticides to be Reevaluated in Brazil
On 17 Aug 2016, the SDA/MAPA (Secretary of Defense Agricultural, MAPA) published a departmental ordinance on administrative procedure for the agronomic revaluation of 117 pesticides registered for soybean rust (Phakopsora pachyrhizi), most of which are bestselling triazoles and strobilurins. Affected companies will have 60 days to submit the scientific evidence to confirm the efficacy of their products against biological targets, otherwise pesticide approvals will be suspended within 30 days.

IBAMA to Register Glyphosate and Triclopyr for Emergency Environmental Use
On 18 Jul 2016, the IBAMA released a normative instruction (IN No.3 on 15/07/2016) concerning the emergency registration of two active ingredients to combat invasive species in reserved land. Glyphosate and triclopyr herbicides which meet specific criteria for a designated use site, dosage and application method could be granted with a 2 year extendable emergency registration.

China ICAMA Hosts Panel Discussion on Efficacy Data Requirement for Pesticide Registration
Four major aspects associated with efficacy data requirements have been clearly defined in the new regulation: comparative analysis with existing pesticide, resistance management, efficacy validation test by subsequent applicant and necessary data to justify the scientificness of multiple compound pesticides.
