摘要
为提升柑橘病虫害的防控能力,对湖南省13个主产县(市)柑橘病虫害发生情况进行调查,明确了该省柑橘主产区主要病虫害的发生规律及防控现状。结果表明:湖南省柑橘主产区大范围发生的病虫害有柑橘黑点病、红蜘蛛、潜叶蛾和柑橘大实蝇,其中黑点病和柑橘大实蝇对果实的危害最为明显,直接影响果园的经济收入;柑橘黄龙病和柑橘木虱主要局限在湘南地区发生,柑橘溃疡病集中在甜橙和柚主产区发生;不同地区的黑点病、潜叶蛾和柑橘大实蝇发生规律存在一定差异。目前,湖南省柑橘病虫防治以化学药剂防治为主,农业防治和物理防治等绿色防控措施为辅,需加快绿色防控措施的推广应用。
Hunan Province is one of the main citrus producing areas in China.In order to promote the control of citrus diseases and insect pests,an investigation on the occurrence and control strategies of these pests was made in thirteen main citrus growing counties and cities of Hunan Province.The results show that citrus black spot disease,Panonychus citri,Phyllocnistis citrella and Bactrocera minax are found popular in the main citrus producing areas of Hunan.Particularly,black spot disease and Bactrocera minax are the most harmful to the fruit,directly affecting the economic income of the orchard.Citrus Huanglongbing and Diaphorina citri mainly concentrate in southern Hunan.Citrus canker mainly occurs in the main producing areas of sweet orange and pomelo.The occurrence regularities of black spot disease,Phyllocnistis citrella and Bactrocera minax have regional differences.At present,the control of citrus diseases and pests in Hunan Province mainly depends on chemical agents with the supplement of green control measures like agricultural control and physical control.It is necessary to accelerate the promotion and application of green control measures.
