By Syndicated Content By Dominique Patton WEI COUNTY, China (Reuters) â Agrichemicals giant Syngenta Group is rapidly expanding its rollout of farm services in China ahead of a huge stock market listing, as it seeks to meet surging demand from farmers crucial to Beijingâs increasing focus on food security. The worldâs biggest crop-protection maker and No. 3 seed supplier says it is boosting grain yields and raising farmersâ incomes just as the pandemic fuels government worries about food supplies and pushes up the cost of key farm materials. That means opportunity for Swiss-based, Chinese-backed Syngenta to grab market share in a fragmented farm chemicals market, positioning the company for growth as Chinese farmers expand their holdings.
