An overview of pesticides registered in China for application on cotton

Posted on 2020-07-02
As the largest cotton producing country in the world, China's total cotton output in 2019 was 5.89 million tons, accounting for 22.5% of the global total, with Xinjiang's total cotton production amounting to 5.02 million tons, accounting for 84.9% of the national total.
 
However, some of the factors restricting the quality of cotton production are cotton diseases and insect pests, including seedling disease, blight, greensickness, spoiling boil disease, aphid and cotton bollworm, which occur periodically and cause considerable pressure on prevention and control. This article is a brief summary of the present status of pesticide registrations used on cotton.
