摘　　要：我国是农业大国,水稻是主要粮食作物。我国人口基数庞大,对水稻的需求量也较大。水稻稻瘟病是水稻生产中较常见的病害,主要由稻瘟菌引起,水稻整个生育期均可能出现,导致水稻大面积减产,甚至颗粒无收。在处理这类病害时,化学杀菌剂的应用成效较好,但化学杀菌剂的随意会导致病原菌抗性问题和化学农药残留,因此需要研究一种低毒性、有效性强的杀菌剂。而植物源天然化合物麝香草酚的主要成分为百里香,这类植物挥发油抑菌性好、安全性高,将其应用于农作物病原菌处理具有较好的抑菌效果。就植物源天然化合物麝香草酚对水稻稻瘟病的防治效应进行探究,为水稻稻瘟病的安全高效防治提供思路。China is a big agricultural country,and rice is the main food crop.China's population base is huge,the demand for rice is also large.Rice blast is a common disease in rice production,mainly caused by blastomyces oryzae.It can occur throughout the whole growth period of rice,resulting in a large area of rice yield or even no grain harvest.In the treatment of such diseases,the application of chemical fungicides is effective,but the random use of chemical fungicides will lead to the problem of pathogen resistance and chemical pesticide residues,so it is necessary to study a low-toxicity and effective fungicide.The main component of the natural compound thymol from plants is thyme.This kind of plant volatile oil has good bacteriostasis and high safety,and it has good bacteriostasis effect when applied to the treatment of crop pathogens.The effect of plant derived natural compound thymol on rice blast control was studied to provide ideas for safe and efficient control of rice blast.
