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.


1. Pesticides registered in China for use on cotton


As per China Pesticide Registration Watch, as of 9th June, 2020, a total of 2,990 pesticide products were registered for use on cotton that will still stay within the valid period, including 2,117 (70.8%) insecticides, 274 (9.2%) herbicides and 198 (6.6%) fungicides. From January 2019 to the present time, there have been 10 new products granted registration for use on cotton, including two insecticides, three herbicides, two fungicides and three plant growth regulators.
