At present, bagging technology has been widely applicated in fruit cultivation. Impact of bagging treatment on the pesticide residues have different results. On the basis of existing achievements, this paper systematically analyzed the influence of different bagging treatments on pesticide residues:such as different ways of applying pesticide, pesticide concentration, number of applying pesticide; bagging materials, bagged layer; the type of pesticide(systemic pesticide, nonendoscopic pesticide); different portions of the fruit, crop varieties and so on. The way of applying pesticide had great impact on pesticide residue, pesticide application after bagging could largely reduce the pesticide residue, and pesticide application before bagging could increase pesticide residues; The four factors including pesticide appliacation dosage, the type of pesticides and fruit portion and fruit varieties on the effects of pesticide residues, had interaction each other. The pesticide applying several times, bagging could significantly reduce pesticide residues and control within the security level. Different bagging materials could reduce pesticide residues, but the impact on pesticide residues had no significant difference. More bagging layers caused less pesticide residues.
