Recently, the group standard review meeting of " Guidelines for the Safe and Scientific Use of Pesticides for Rice, Wheat and Maize " organized by China Pesticide Industry Association and led by Hailir Pharmaceutical Group was held in Qingdao.

	

Rice, wheat and corn are the three major food crops in China and the most important food crops in the world. The production and income increase of the three major grain crops is directly related to the effective supply of agricultural production and provides an important guarantee for food security. The scientific use of pesticides in the planting and production links is very important. The group standards of ' Rice Safety Scientific Use of Pesticides Guide ', ' Wheat Safety Scientific Use of Pesticides Guide ' and ' Corn Safety Scientific Use of Pesticides Guide ' reviewed in this review are important components of this series of group standard projects. The three standards were officially launched in November 2011, which lasted for two years. After several rounds of consultation, discussion, modification and improvement, they finally entered the review. 
This review will take the form of a combination of online and offline. As the lead unit for the formulation of the above standards, the group fully embodies the industry leadership 's recognition of Hailer 's professional and in-depth research on the three major crops of rice, wheat and corn.
