- Abstract
[Objective] To discover the types of plant diseases and insect pests in Chrysanthemum morifolium cv. Fubaiju in Hubei Province, and to make effective control measures for brown spot. [Methods] During the growth period of C. morifolium cv. Fubaiju, the types of plant diseases and insect pests were preliminarily investigated. Randomized block experiment on brown spot was designed to carry out comparative tests on chemical reagents and filed control. [Results] Investigation showed that there were five types of pests and diseases, which were brown spot, downy mildew, virus disease, powdery mildew and aphids. Among them, brown spot was the most serious, followed with virus disease. Results of control effect test showed that 600 times diluents of 3% polyoxin and 800 times diluents of 50% carbendazim had relatively ideal control effects. After the second drug application, control effects reached 80. 88% and 79.66% ; and disease indexes decreased to 9.16 and 10.23, respectively. [Conclusions] Both 600 times diluents of 3% polyoxin and 800 times diluents of 50% carbendazim could control the development and spread of brown spot, which were relatively ideal reagents.
