杂草的生物防治是草害综合防除的重要组成部分。它是利用寄生物、昆虫等的生物作用将某一种杂草的密度控制在经济允许水平之下,不致成灾,而达到防治的目的。近二、三十年来,由于长期地、大量地施用化学农药来防治病虫草害,而产生了环境污染问题。因此,生物防治越来越引起人们的兴趣和注意。现将有关国内外杂草生防资料加以荟集整理,并对杂草生防的展望进行粗浅剖析,以供参考。
The biological control of weeds is an important part of the comprehensive control of weeds. It is the use of parasites, insects and other biological role of a certain weed density control under the economic allowable level, not disaster, and achieve the purpose of prevention and treatment. Nearly two or three decades, due to the long-term, large-scale use of chemical pesticides to control pests and diseases, resulting in environmental pollution problems. Therefore, biological control has drawn more and more people’s interest and attention. At present, the biocontrol data on weeds at home and abroad are compiled and summarized. The prospect of biocontrol of weeds is briefly analyzed for reference.
