Embodiment Construction

[0015] The present invention will be further described below in conjunction with embodiment.

[0016] test 1

[0017] Bacteriostasis test of pesticides on the fungus of anthracnose

[0018] 1. Identification of pathogenic bacteria

[0019] 1.1 Potato dextrose agar (potato dextroseagar, PDA) medium: glucose 20g, potatoes 200g, agar 20g, distilled water 1000mL.

[0020] 1.2 Isolation and purification of pathogenic bacteria Cut out 5mm×5mm tissue at the junction of diseased anthracnose, disinfect in 70% alcohol for 5s, disinfect with 0.1% mercuric chloride for 30s, rinse with sterile water for 3 times, place in On the PDA plate, after culturing in an incubator at 25±2°C for 5 days, the hyphae at the edge of the colony were picked for isolation. The obtained strains were further purified and cultured and stored in a refrigerator at 4°C until use.

[0021] 1.3 Inoculation of pathogenic bacteria Anthracnose bacteria cultured in PDA for 7 days, and the edge of the anthracnose bac...

Abstract

The invention relates to the technical field of plant protection, in particular to a control method for tsaoko anthracnose. The prevention and treatment method for the tsaoko anthracnose comprises the following steps: S1, land selection and garden cleaning: selecting a land parcel without epidemic situation and insect attack outbreak, and disinfecting soil with 50% carbendazim; s2, seed treatment: selecting a disease-resistant variety, performing seed treatment before sowing, and soaking the seeds in warm water at 50 DEG C for 30 minutes; s3, cultivation management: increasing the shading degree, improving the ventilation condition and reducing the humidity of the cultivation area; in the seedling stage and the vigorous growth stage of the amomum tsao-ko, spraying Difengtian dew or medium trace element leaf fertilizer; in the earlier stage of flowering and after harvesting, fully decomposed organic fertilizer is applied, diseased shoots are cut off in time, and diseased fruits are removed in time. According to the method for preventing and treating the anthracnose of the Amomum tsao-ko, the occurrence of the anthracnose of the Amomum tsao-ko can be effectively controlled, agricultural measure links such as land selection and garden cleaning, seed treatment, cultivation management and the like are emphasized, and the harm of the anthracnose of the Amomum tsao-ko is scientifically solved in cooperation with spraying of a novel chemical agent.

Description

technical field [0001] The invention relates to the technical field of plant protection, in particular to a method for preventing and treating grass fruit anthracnose. Background technique [0002] Caoguo (Amomumtsao-ko) is a perennial evergreen herbaceous plant belonging to the genus Zingiberaceae. It has a long history of food and medicine in my country. Medicinal functions such as cutting off malaria. At present, according to the investigation of grass fruit diseases and insect pests in Nujiang Prefecture from 2014 to 2018 by the expert team of Yunnan Academy of Agricultural Sciences, the grass fruit leaf spot disease has the greatest impact on yield and quality, with a high incidence and a wide range of occurrence. The total area of ​​disease occurrence in the state is 1.67×10 4 hm 2 , The average annual loss of Tsaoko is 5030 tons, and anthracnose in the planting area can cause the loss of Tsaoko to reach 10-30%. [0003] Grass fruit anthracnose is mainly caused by a...
