China Solicits Comments on List of Class I Agricultural Pests

On 4 June, the Chinese Ministry of Agricultural and Rural Affairs invited a 30-day consultation on the list of Class I agricultural pests, which was drafted as per the “Regulation for the Prevention and Control of Agricultural Pests”.

The regulation was enacted earlier this year, aimed to clarify the responsibilities of government departments at all levels and entities engaged in agricultural production and pest control service, as well as standardize the practices of pest monitoring, forecast, prevention and control.

The Class I agricultural pests are perennially pests impacting an extremely large area which may lead to an extremely serious loss in agricultural production. The development and occurrence of these pests and diseases are monitored and treated under a special response program developed by MoARA.

A total of 16 pests and diseases will be identified as the Class I agricultural pests, some of which are invasive pests and only a few pesticides have registered the targeted uses.
