系统调查鉴定了菊花病毒病、霜霉病、叶斑病、叶面害虫、蚜虫天敌种类及其流行规律,研究了组培脱毒苗、地膜覆盖移栽、与高秆作物套作、摘顶稍、利用昆虫天敌及化学防治等综合治理效果.测定了农药残留量.结果表明,菊花组培苗脱毒率在60%左右,脱毒苗增产50%以上,叶枯病、霜霉病病叶率下降28%~30%,虫口密度下降40%,在收菊花前1个月使用拟菊酯杀虫剂,农药残留量低于允许值,不会对菊花和环境造成污染.
A systematic investigation identified chrysanthemum virus disease, downy mildew, leaf spot, foliar pests, aphid natural enemy species and their prevalence, study of tissue culture virus-free seedlings, plastic film mulching transplanting, and high-stalk crop sets, Slightly, the use of insect natural enemies and chemical control and other comprehensive control effect.Determination of pesticide residues.The results showed that the detoxification rate of chrysanthemum tissue culture seedlings is about 60%, the virus-free seedlings yield more than 50%, leaf blight, downy mildew disease Leaf rate decreased by 28% to 30%, population density decreased 40%, 1 month before the use of chrysanthemums to be used pesticides, pesticide residues below the allowable value, will not cause pollution to the chrysanthemums and the environment.
