Cao Yazhong, Chief Expert of this research team from the IPP says, grubs are the principal culprit for peanut planting in China. They can cause sprout deficiency at the seedling stage and eat fruits exclusively at the fruiting phase, generally decreasing the yield by 20~30%, and even by 60~70% when outbreak happens, just as farmers often say "the number of grubs is equal to peanuts or even more". And in order to control against grubs in some particular areas, farmers usually use highly toxic pesticides like carbofuran and phorate, which subsequently cause food security problems.

Yang Daibin, inventor of the 18% fipronil•chlorpyrifos CF from IPP introduced, it consists of two active ingredients with different mode of action. It is produced with sophisticated technique, and the microcapsules in this formulation are just several microns with above 95% of active ingredients encapsulated, thus makes this microcapsule formulation of high safety, high efficiency and longer duration.

In 2013, it has been applied in more than 200,000 mu (13,333 hectares) in the Provinces of Shandong, Henan, Hebei and Liaoning. And in 2014, as estimated by experts, its application area is about 1,000,000 mu (66,667 hectares).
