Pesticides registered and used in locust in China

UNITED NATIONS, Feb. 14-A number of East African countries are suffering serious locust infestation, with Kenya experiencing its worst in 70 years, which, if left unchecked, could grow 500 times in scale by June, a UN spokesman said.

 

According to the FAO, the increasing desert locust swarms in Ethiopia and Somalia have continued to migrate into Kenya, where they spread to 14 northern, central and southwest counties, reaching within 200 km of northeast Uganda and southeast South Sudan, stretching from west Africa all the way to Pakistan and India.

 

Locust, a large-sized insect, is a short-horned grasshopper of migratory habit, which attacks crops or green vegetations. It causes extensive damage due to its feeding behaviour. The most devastating of all locust species is the Desert Locust (Schistocerca gregaria). Locusts have a high capacity to multiply, form groups, migrate over relatively large distances (they can fly up to 150 km per day) and, if good rains fall and ecological conditions become favorable, rapidly reproduce and increase some 20-fold in three months.

 

China currently has become the world’s largest pesticide producer. In 2019, China’s pesticide TC output reached 2.254 million tons, an increase of 1.4% year-on-year, and pesticide exports were 1.470 million tons, a slight decrease of 1.5% year-on-year. Among them, the African is China’s fifth largest export region, where the pesticide export value in 2018 was 820 million US dollars, up by 14.7% year-on-year, showing a rapid development trend. The outbreak of “African locusts” may stimulate the growth of China’s pesticide exports.

 

At present, there are 27 pesticides registered and used to control locust in the valid period in China, which are as follows:
