BEIJING — Chinese police have intensified the crackdown on crimes of counterfeiting seeds, pesticides, fertilizers and other farming supplies during the plowing season, public security authority said on March 22.

Du Yan, an official from the Ministry of Public Security, told a press conference that public security departments at various levels have made progress in the investigations into farming supplies-related criminal cases.

Police in provinces including Liaoning, Heilongjiang, Jiangsu and Fujian have cracked a number of cases involving the manufacturing and selling of counterfeit and low-quality seeds, fertilizer, pesticides and veterinary drugs.

In one case involving a bio-tech company in the South China's Hainan province, police seized more than 50 kinds of counterfeit pesticides with a total worth of over 19 million yuan ($2.67 million).

Public security departments have strengthened the collection of clues to counterfeiters' dens and detection of online sale of fake farming supplies, said Du.

Police operations have targeted all the links, elements and chains of the cases to root out such crimes.

Cooperation between the police and departments of agriculture and market regulation has been strengthened in information sharing, product examination and case transfer.

Du said the ministry will continue to strengthen coordination and guidance for law-based, prompt and harsh crackdowns on such crimes.
